TomTom Spark (Runner 2) In-Depth Review


It’s been about 50 days since I started testing the TomTom Spark watch (also branded as the Runner 2).  These were TomTom’s new entrant into the market by combining an optical HR sensor with music and GPS tracking capabilities.  In many ways the core of the unit isn’t super different than past GPS watches from the company, yet at the same time it makes those slight but important additions that make it incredibly competitive – especially in the mid-range running watch category.

For this review TomTom provided me a final production unit back in late October.  Additionally, I also purchased my own TomTom Spark unit as well to test.  My testing has been on a mix of both of those units, and following this review I’ll return the media loaner to TomTom like normal.  That’s just the way I roll.



The Spark comes in a bunch of different variants, though the internal packaging is actually the same on all of them (unless you get the headphones).  That’s because it’s only the innards that differ between the different models.  Externally of course on the box it’ll say which model you’ve got.  For example, on this music one, you can see it lists music as a feature – but for this model I bought, it didn’t include the headphones (that’s a different bundle).

Next, note there are different sizes, which is just the wrist band.  The pod that goes in the wrist bands are all the same.  And remember, it also could be named differently too (Runner vs Spark).  In any case, the box:


Inside the box there aren’t really too many pieces.  You’ve got the watch, the charger, and a chubby little manual:


The charger is actually different from previous generations.  It’s less plump, and is a bit more aero.  Thus, it won’t work with previous TomTom watches.  The cable both charges and allows download to Mac/PC.  But of course you can also download via your phone (iOS/Android).



Next, with the watch it comes as a little pod that fits into the wrist strap.  Because the pod is a bit different, it’s not compatible with older TomTom straps.  You can get different colored straps, as well as different sized straps.

You navigate through the menus using the little joystick thingy at the bottom.  The screen is NOT a touch screen.


Meanwhile, if you flip it over you’ll see the optical sensor on the back.  Obviously, if you didn’t buy the version with an optical sensor then you’ll just see a black backing.


Finally, the manual.  It’s super-chubby, but actually doesn’t have a lot of content in it.  Rather, you can use it to learn how to plug in a USB cable in 48 different languages.


With that, let’s talk size.

Size & Weight Comparisons:

First, you’ll notice that the TomTom Spark (blue) is a bit slimmed down from the TomTom Cardio (red) units.  Not so much the pod itself, but rather the strap.  The strap lost the thicker edging and also just some of the bulk.


They also have a pile of different colors/combos:



This thinner strap translates into lost weight as well.  If you look at the TomTom Spark, it comes in at 51g (for the version with the optical sensor & music):


However, if you have the black strap, you’ll save a bit of weight – it’s only 47g (45g for the small strap):


The pod itself is 35g, though you can’t very well run with just that.


Meanwhile, the older TomTom Cardio comes in at 63g:


For reference, a few other watches’ weights:

Garmin FR225 (optical): 53g
Garmin FR235 (optical): 40g
Garmin FR620 (non-optical): 42g

Next up is size.  Here’s a round-up of most of the more popular current generation GPS watches on the market, and how things look size-wise.  The TomTom Spark is 2nd from the right, in the blue configuration.  Like in real life, it appears slightly slimmer when you go with the black strap.


Left to right: Garmin Epix, FR920XT, Suunto Traverse, Suunto Ambit3 Peak, Polar V800, Garmin FR225, Garmin FR630, Garmin FR235, TomTom Spark, Garmin FR25

And here’s the depths of them.  The rolling pin is held level (by two 9V batteries), thus allowing you to see the height between the table and each watch face).


Ok, comparison time is over.  Let’s start using the darn thing.

Basic Overview:


For those that have experience with past TomTom GPS watches, it’s probably easiest to know that outside of the new feature areas – almost everything else remains the same.  Meaning, only these four things have changed:

A) Activity Tracker Added
B) Music Storage/Playback via Bluetooth Added
C) Optical HR sensor changed
D) Smaller/thinner strap than Cardio version

Virtually every other function of the watch remains the same as its predecessors.  About the only minor menu shift you’ll notice is that they’ve moved the two secondary data fields from the top of the screen to the bottom of the screen.

Now, that’s not to say that there aren’t backend changes – because there are.  The company has completely revamped their web platform in a shift off of MapMyFitness to a self-hosted site.  Those changes will start to become more evident in the coming months as they shift from ‘duplicating existing format’ mode to ‘new features’ mode.

Of course, in the meantime there are certainly new features like the ability to see step tracking and distance walked each day.

For those unfamiliar with the watch, it’s probably good to start by knowing there are a bunch of different versions of the device:

TomTom Spark GPS Watch: €149/$149USD
TomTom Spark Cardio GPS Watch: €199/$199USD
TomTom Spark Music GPS Watch: €199/$199USD
TomTom Spark Cardio & Music GPS Watch: €249/$249USD
TomTom Spark Music GPS Watch with Bluetooth Headphones: €249/$249USD
TomTom Spark Cardio & Music GPS Watch with Bluetooth Headphones €299/$299USD

What’s notable here is that all versions of the TomTom Spark are multisport, unlike the past where they had a dedicated runner and a separate multisport version.  Basically, to summarize, you’ve got these core features that you’d pick from/add:

GPS Multisport (all watches)
Music via Bluetooth in Music versions (option)
Optical HR in Cardio versions (option)

All versions have activity tracking, and all versions have multisport capabilities (running, cycling, pool swimming).  And all versions support connecting to Bluetooth Smart Heart Rate Straps and Speed/Cadence sensors.  Whereas the Cardio versions also add an optical HR sensor, and the Music versions allow you to playback music stored on the watch via Bluetooth audio headphones.

Got all that?  Good.

The Optical Sensor:


Probably the most important thing to know about the internals of the watch compared to past TomTom units is that they’ve swapped out the optical sensor for a different brand.  Readers will remember I’ve been a bit nervous about this, since the brand of optical sensor in fitness watches is the most important thing between a crappy accuracy and rock-solid accuracy.  The differences in optical sensor quality is vast, and in general, most suck.

In TomTom’s case they went from licensing Mio’s optical sensor technology, to utilizing a previously unheard of company called LifeQ.  This would be LifeQ’s first product on the market.  Note that technically LifeQ is more about the software than the hardware.  They essentially guide companies (like TomTom) through a package of hardware (optical sensor components), and then layer in their software algorithms.


Since I wrote up a bit about them in my preview post after I visited TomTom’s headquarters and had a conference call with the LifeQ team, I figure much of those few paragraphs are relevant here too.

The key theme when talking to TomTom about the Spark was really about them building a platform for the (or their) future.  This was both on the device side, but also on the web platform.  They noted that while cost of the LifeQ optical solution was certainly less than the Mio/Philips offering, it was actually the deeper integration and future potential that was the major driving factor.  With Mio/Philips, the sensor was essentially plug & play – providing just heart rate as an output to the watch.  That was great for the Cardio, and worked well.  But they were concerned that long term it wouldn’t be as competitive as other companies added more and deeper features.

Whereas with the LifeQ solution they felt that they’d be able to get more ‘out of’ the solution.  In discussing their roadmap during the conference call with LifeQ, I can’t argue with that approach.

To begin, LifeQ is a mostly South African based company that has offices in Atlanta and soon Boston & San Diego.  At 70 employees strong, it’s certainly not four guys in a garage somewhere.  Their focus is really on the bio-mathematical algorithms that are behind the sensor packages they put together.  They don’t actually sell sensors, or hardware.  Rather, they are mostly about algorithms and down the road, big data-esque type solutions.


That said, this is LifeQ’s first product.  That’s both good and bad.  On the obvious-bad front, it means that they lack the real-world user usage that can only come with deploying thousands of units.  No amount of studies or test runs (no matter how many years they’ve done them) will replace that.

On the flip side (the good side), with what is effectively one customer (TomTom) deciding their future as a company, they’re incredibly motivated to ensure they get it right.  They noted they really wanted to partner with TomTom, versus various knock-off brands seen across the CES floor, due to TomTom’s specific baseline requirement that it be just as good (or better) than the existing Mio sensor (in their current Cardio lineup).  The agreement between LifeQ & TomTom is not exclusive, and LifeQ certainly sees a world of potential partners down the road outside of TomTom.

As I alluded to earlier, LifeQ doesn’t make the sensors.  Instead, they take off the shelf components and put forth reference designs to companies like TomTom.  TomTom could, if they wanted to, come to LifeQ with a preferred set of chipset and sensor partners, but in this case they let LifeQ run with what they specialized in (a wise move).  As such, the TomTom Spark uses an multi-wavelength PPG (photoplethysmography) optical sensor from Osram (the SFH-7060).  That sensor includes 1xRed LED, 3xGreen LED, plus a single IR sensor.  That set of multicolor LED’s helps them to ensure greater accuracy across more skin tones.  For example, some companies (i.e. Valencell) use a yellow LED in addition to the green.  LifeQ specifically selected the red over yellow, because it would give them more flexibility down the road for blood oxygenation levels.

You can clearly see the different colored LED’s here. The 1xRed LED to the left, the 3xGreen LED’s in the middle, and then the IR to the right.


Next, they layer in a Texas Instruments AFE 4404 to manage the optical sensor, before calling it done on the hardware layer.  Now it’s really important to note that the firmware that LifeQ has is probably more important than the sensor set selected.  Meaning, just because you have a good sensor does not mean you have good data.  The hard work is taking that raw data stream and making something pretty out of it.  An area that the vast majority of optical sensors within cheaper fitness products today hose up.

As I noted numerous paragraphs ago before we got distracted on company background, a significant reason they selected LifeQ was for the future expandability.  For example, LifeQ is able to measure RR, and then calculate HRV (while resting).  Further, they’re able to calculate VO2Max and VO2 (continuous).  And down the road they’re able to measure lactate threshold, sorta similar to BSX.  All features that could make their way into the TomTom Spark through firmware updates.

Right now TomTom has committed to getting VO2Max and the recording of HRV/RR data into the .FIT files by early next year.  Whereas features like oxygenation levels and lactate threshold probably aren’t on the near-term update list for TomTom, even if LifeQ is able to deliver them.  I’d suspect that any inclusion of those features would probably target a different (more advanced) user audience than the current TomTom watches aim for.  Fwiw, you can actually dive into many of LifeQ’s white papers on their site. Obviously it’s biased in that they’ve published it, but still interesting nonetheless.

Now how did all this optical sensor talk play-out in real-life after about 50 or so days of usage? Let’s dive into it.



To start with the watch, we’ll start with running.  But there are a number of sport modes you can select (on all versions), they are:

Running (GPS on, for outdoors)
Treadmill (GPS off, for treadmill)
Cycling (GPS on, for outdoors)
Indoor Cycling (GPS off)
Swimming (GPS off, for pools only)
Gym (GPS off, for indoors)
Freestyle (GPS on, for whatever the heck you want)
Stopwatch (when you’ve simply given up)

All of these modes then show the type of workout later on while online.  But again, in our case, we’re going running:


At this point it’ll find satellites and also acquire your heart rate via the optical sensor.  If you have a HR strap, it’ll talk to that instead (if configured as such).  Note that the unit does NOT support any footpods.


I found that as long as I connected the watch to the TomTom platform, it downloaded the GPS quick-assist database, which enabled it to find GPS satellites in under 10-15 seconds virtually every time.  You can validate your quick assist information is up to date by pressing down from the main screen:


In running mode, you can change different training options.  These are:

None (basically free mode)
Goals (Run towards a set distance, time, or calorie goal)
Intervals (Run a structured interval workout)
Laps (automatically triggered laps for time, distance, or manual)
Zones (Set a range to stay within for pace, speed, or heart rate)
Race (Race against a historical activity, a standard distance, or a custom distance)

The vast majority of my time with the watch I was in either ‘None’ mode (free mode) or running intervals.

Before we start running, you can slightly configure data screens.  Specifically, you can configure the two metrics along the bottom to stay put with fields of your choice.


The main (bigger) screen simply will iterate through all of the metrics as you press the buttons.


The metrics that are shown are: Clock, Duration, Distance, Pace, Avg. Pace, Speed, Avg. Speed, Calories, Heart, HR Zone.

Again, for the metrics above, you press up/down to change the main field.  The two smaller fields do not change.  You’ve also got three different graphs related to HR that’ll show up when you press to the right.  These are not customizable.

Once you’ve selected a mode, you’ll go ahead and begin the timer from the main running screen.  At that point it starts recording and you should start running.

As you run, the metrics will display showing your current status:




One of the most common questions on GPS watches is pace stability.  In my case, I’d give pace stability a good but not great rating.  It mostly kept my pace stable, but did seem to wobble a tiny bit more than other GPS watches I was using at the same time (Suunto Ambit3, Garmin FR920XT).  Not enough that it was a deal killer, but just a tiny bit more.

Within the interval mode, you’ll configure the interval portions such as work, rest, and warm-up/cool-down.  These can be set for time or distance:


Then, while running the interval it’ll keep you on track with which set you’re on (i.e. Set 1/4).

However, the interval mode does not specify *what* to do for each section.  Meaning, it doesn’t tell you to run X pace, but instead just that you need to run Y time/distance.  So it’s not as advanced as some units.

Also, to my disappointment the interval mode doesn’t take advantage of the Bluetooth headphones to announce that an interval is about to start (or your finishing splits).  I asked TomTom and they said that’s coming down the pipe though.

So what about GPS accuracy?  Well in general, things did quite well.  Here’s a run-down of my activities and the different watches I was using and distances:

In general, I’m interested in cases where a given unit is substantially different than others.  And if so – why.  Of course, I’m always looking at GPS tracks, because it’s quite possible for both units to have the same end-GPS distance, but with equally horrible tracks.

In the majority of cases, the TomTom tracked very well.  Still, there were a few odd ducks that I checked into.  For example, on Nov 12th it showed a pretty big difference for a hill repeat run I did in the city.  In poking at it, I actually don’t see an obvious explanation there for being so much shorter (1/3rd of a mile).  Only the Suunto Ambit track looks problematic (a rarity for it):


Looking at some of the other big difference activities:

Nov 14th: Spark somehow misaligned one of my loops by a few city blocks (see below)
Oct 28th: 5.00mi (Spark) vs 4.90mi (Epix): The Epix cut corners in the city, Spark was correct.
Sept 24th: 6.07mi (Spark) vs 5.93mi (FR920XT): No obvious differences between track, rather odd (see below)

For example, below is the Sept 24th one, while the purple track shows it going into the water, it’s still parallel where I ran (just offset perhaps 10-20m for a brief chunk).  Obviously, not ideal, but also doesn’t account for the gap of .14 miles.


On the Nov 14th run, it did some super-wonky satellite shift on one of my loops around that area.  You can see I was doing loops between two bridges, and for some odd reason, it shifted one of those loops west a ways, causing a spike in mileage.  Oh, and the FR920XT going waterborne? That section is actually underground, so something weird happens there.  The TomTom, Suunto, and FR235 did handle it well (I’d say about 80% of the time units get it right).


My running turf for this test period included mostly open-sky running along the beach in Mexico, extensive city running in Paris, mountain/forest running in Alberta (Canada), and some trail running in Delaware (US).

Overall, outside of calling out these specific oddities, the unit actually did perform pretty well.  I know it’s easy to look at just the odd duck cases, but do pay attention to the entire table – since it shows that in general, despite challenging conditions (mostly city running), it held its own.

Lastly, but most importantly – the optical sensor accuracy.  In my testing I found that it did good, but not great.  Specifically, as the weather cooled in the last few weeks, I saw issues where the first few minutes (usually 3-4, but in one case as long as 9 minutes) the unit struggled to accurately display my HR.  It would always undercut my actual HR in these initial minutes.  Once it locked onto my HR though, it almost always nailed it for the rest of the session – no matter what wonkiness I did running pace-wise. Once past that point, it tracks along with the three other HR sensors I was wearing, no problems.


Here’s another example of cooler weather runs.  Note, that none of these were terribly cold – about 50-55°F (10-13°C).  The TomTom Spark briefly had problems in the first two minutes where it dropped low (blue).  The green line you see all wobbly is where the Scosche managed to catch the Velcro on my t-shirt and pulled off and I hadn’t realized it for a moment, so it’s wobbly until I fixed it.  That’s more of a ‘me issue’ than a ‘them’ issue.


Here’s another run, where the unit has trouble during first few minutes finding lock.  But once it finds it – boom, good to go!  Though, you see one brief blip at the end of the 5th interval.


In warmer weather I saw no issues at all with the optical sensor in the first few minutes.  For example, this run here I only saw one tiny segment of a few seconds where it diverged.  It’s entirely possible that I had adjusted the band at that moment for something.


Another example here, where the two units tracked near perfectly.  You see the Scosche ramp up a few seconds slower this morning than the TomTom, but nothing appreciable.  Towards the end you see the TomTom briefly dip for a few seconds, but again, only by a few BPM.


Next, a lukewarm run in the Canadian mountains.  Again, near identical.  You see two random drops of 0BPM data on the Garmin Epix.  Not sure what that’s all about.


Finally a nice fall run in Delaware, where the temperatures dropped as sunset approached, but not overly cold.  You can see it near perfectly matched the other HR sensor (and actually tracked slightly better in the first minute or so).


So ultimately, the HR sensor is pretty good for running, with some minor caveats that it seems a little more susceptible to the first few minutes getting warmed up, than some other sensors out there.  Not a deal-breaker, but something to be aware of.

Note that optical sensors in general struggle on your wrist in cooler weather.  The TomTom Spark probably would have gotten a better review had I posted two weeks ago, since the weather was largely warmer then and didn’t manifest itself until cooler weather.  I’d note though that many units struggle here.  For example, I saw similar issues a year ago with the Mio Fuse during the winter (albeit much colder weather).



The TomTom Spark has a basic cycling mode that enables you to support cycling sensors (the speed/cadence sensor), as well as displays your metrics in speed (MPH/KPH) rather than pace.  Further, it helps to automatically identify those activities later when looking at them via the app or website (or to 3rd party sites).

To select the cycling mode, simply choose it from the list when you press to the right once:


Additionally, you can also use the indoor cycling mode, which disables the GPS and relies on a Bluetooth speed sensor for distance/pace.  This sensor is not required however, so if you were to just join a spinning class you could still just have it categorized as indoor cycling.

To pair the speed/cadence sensor, you’ll go into the sensors menu within the watch.  It’s super basic, and you can’t save multiple sensors if you have multiple bikes:


In my case, I tested it with the Wahoo BlueSCv2 (which is dual ANT+/BLE), it worked just fine.

Whether indoor or outdoor cycling, you may end up mounting your watch to your bike (such as with this simple $10 adapter).  In doing so, you’d obviously lose optical HR since it would no longer be on your wrist.  So in lieu of that you can pair to a separate Bluetooth Smart heart rate strap.

This allows you to still display/record HR, even when it’s not on your wrist.


Using a strap may be a good idea anyway while cycling, because in my testing the optical HR hasn’t been very accurate while wearing it on my wrist riding.  This wasn’t a huge surprise to me, as most (but not all) optical HR sensors worn on one’s wrist struggle here.  For example I’ve seen lackluster cycling optical HR performance with the Apple Watch, Fitbit Surge, Microsoft Band (1 & 2) and Samsung Gear Fit. Meanwhile, I’ve generally had good luck with the Mio Link on my wrist from a sensor standpoint (while I usually wear the Scosche Rhythm+ optical HR sensor, it’s not for one’s wrist).


I’ve also tried it on the inside of my wrist, which is usually a much easier way to get accurate results as it’s a bit more ‘fleshy’ and not as bony.  In this case, no such luck:


For example, in the below you’ll notice the first 25% of the ride it has me just wandering along at 110-120BPM.  In reality, I’m where the Scosche has me at 140’s.  Then, it locks on for a while, before eventually having quite a bit of trouble the rest of the ride.


Yet on a different ride this weekend, it actually tracked quite well for perhaps 80% of it, but then had a really tough time in a few key chunks:


Indoors, I saw no problems at all with optical HR tracking – it tracked beautifully there:


Ultimately, I’m not really sure where to place HR accuracy here in terms of cycling.  I think it’s basically just a crapshoot while outdoors.

(Note: All of the charts in these accuracy sections were created using the DCR Analyzer tool.  It allows you to compare power meters/trainers, heart rate, cadence, speed/pace, GPS tracks and plenty more. You can use it as well, more details here.)

Swimming (Pool):


The TomTom Spark (all versions) includes the ability to track your pool swims.  It DOES NOT track openwater swims. It has no openwater swim mode, though some people have used existing TomTom watches in the ‘Freestyle’ mode with mixed success.

Further, in Swim mode, the optical HR sensor is not enabled.  TomTom says that perhaps down the road if testing pans out, they’ll enable it.  But today, when in swimming mode it’s disabled (but I’ll show you what happened when I tried it anyway).

First up, to get into the swim mode you’ll go ahead and select the ‘Swim’ mode.

Before you press start though, you’ll want to configure your pool size by clicking down to ‘Settings’, and then selecting ‘Pool Size’.  I had pictures of all of this in the pool, but they came out looking downright horrid. Sad smile  See:


It’s here you can specify the exact number of meters or yards your pool is.  You’ll first select the numerical length, (both whole and partial numbers), and then meters or yards.  Super easy.

The configuration options in terms of training are super-limited, and honestly kinda wonky.  For example, if you want to configure sets, you have to do so using ‘Laps’.  Except within the distance option for laps you’d do so in miles or kilometers.  For metric folks, miles isn’t too bad (though, for my 33 1/3m length pool – it can still be tricky).  But miles is just a mess for folks swimming in pools measured in yards.

In any case, with all that set, it’s off to start your set by pressing go.  Once you start swimming you can view the following metrics:

Available Swim Metrics for Main Screen: Lengths, SWOLF, Strokes, Calories, Avg Speed, Miles, Duration (Time Elapsed),  and Clock Time

Further, you can configure two metrics along the bottom, such as distance and time.

Now frustratingly (more mind-boggling actually), you (still) can’t display yards or meters.  Who on earth shows their swim workouts in miles?  Nobody.  That’s who.  Yes, I know, for metric folks you could see meters.  But I’d bet that TomTom sells more of these watches in the US than Metric countries, so it would seem halfway logical to offer both (like every other swimming watch).

In any case, as you swim these metrics will update in real time – typically at the end of each pool length.  As is the case with all swimming watches, it works both with flip and open (non-flip) turns.  However, like most swimming watches you’ll want to ensure you press off the wall crisply.  These watches work by measuring acceleration, and unexpected (or lack of) changes to that can cause problems for all companies.

Afterwards, online you can see your splits from the swim session, divided up by lengths:


Now in my testing, I found things mostly good.  It made one lap error on a recent swim, missing a turn/length, where the FR920XT didn’t miss that length.  To be fair, that was the same length that I totally whiffed the wall and basically just did a flip turn sans-push. I’m not going to hold that over the TomTom’s head.  Note in the above case, I split the workout into two pieces – one without HR, and then one below with HR.

Which brings us to the HR piece.  In this case, I just put the watch into a generic mode, called Freestyle.  In this mode it records your HR, but doesn’t record swim metrics.  So it won’t capture aspects like lengths, distance, or the fact that you were swimming.  It just captures your HR.

I then set out for a short set to see how well it’d track.  I had actually also worn the HRM-SWIM from Garmin to compare HR’s, but somehow that accidentally got into drill mode and oddly I learned it doesn’t record HR data in drill mode.  So, I have just the TomTom data, but honestly, I can pretty much walk you through the accuracy there.

I basically did 6 lengths with it, with the first two lengths at an easy pace, and then the next two lengths springing, and then final two lengths back to an easy pace:


Obviously, the Spark sensor didn’t get the memo.  It appears that it was entirely lost for the first two thirds, but seemed to actually find the plot for the last two lengths, as that HR would be more akin to what I was doing the rest of my swim per the HRM-SWIM.

Now again, TomTom doesn’t advertise they can do this.  In fact, they purposefully turn off the optical sensor in swim mode.  So this is more of a curiosity test than anything else.  Further, optical sensors in the water can be finicky in that it might work for someone else, even if it doesn’t work for me.

Activity Tracker Usage:


Yes, the TomTom Spark has an activity tracker in it – like every other connected watch made in the last 12-18 months.  But how they implemented it is both different and sorta intriguing.  Parts of which I love, and parts of which I hate.

First up – obviously, it counts steps.  It does this anytime you’re wearing it – so that you can see how many steps you walked as well as how far you’ve walked (or ridden) in total each day.


This steps page is accessible by tapping the left button, which changes the display to the activity tracker pages.


While this sounds like it’s pretty innocuous, it isn’t.  See, it’s slow.  Every time I tap I have to wait a few seconds for the screen.  There’s lag, and that’s annoying.  But more than that – is the fact that I just can’t see my darn steps on my home screen.  I don’t care to see the clock in gigantic letters.  I’d rather see my steps or progress towards my goal somewhere on the screen, with the clock a bit smaller.  You know, like every other activity tracker on earth.

So what does TomTom do different that I DO like?  Well, they’ve somewhat shifted away from the idea that you’re going to have a perfectly even daily step count.  And instead overlaid a bit of a 7-day step goal.  The idea being that for various reasons you might have a lower Monday but then make up for it on Tuesday.  For the non-active person that might sound like a bad idea.  But for the athlete trying to recover – that’s actually exactly what you want.  It helps to even out those rest and peak days.


On the steps, the numbers seemed to be in the same ballpark as those of the Withings Activite. As usual with activity trackers, each company tends to do a bit different when it comes to algorithms, so I wouldn’t overthink minor differences like 5% or so.

One minor thing to note is that the distance travelled pages of the activity counter do include cycling.  So if you do that, it’ll probably skew your step/walking mentality a bit.


Next, is sleep. The unit tracks sleep in basically the same manner as steps – on both a daily and running total:



I found the numbers pretty much matched what I got from the Microsoft Band 2 and the Withings Aura. All of this is then uploaded to the TomTom MySports site, via either the desktop uploader or the mobile phone app. Note though that neither connect to Apple Health, though TomTom says that’s on the way.

Music Playback:


The TomTom Spark is one of the few GPS watches out there that has storage for music, as well as Bluetooth playback.  You must have Bluetooth headphones to playback the sound, as there is no headphone port (that would impact/limit waterproofing levels).

You can buy a bundled TomTom Spark that includes headphones, or you can purchase your own.  If you buy the bundled version, you’ll get these ones below:


They look a little…bulky…but in reality I’ve found they actually work really well.  In fact, I’d say just as well as some of the different test headphones I’ve bought that cost $130-$180USD.  But more on that in a second.

The headphones have two buttons on them, and charge via micro-USB.  The buttons allow you to control audio volume, and change the power/pairing state.  To do so you’d hold down the middle button till it goes crazy blue/red flashing.  When it comes to pairing, you’ll do that before you start your run, by pressing up to launch the pairing screen:


Then, once you go to start a run it’ll search for your powered on headphones.  I’ve found this to occasionally be kinda finicky, most notably with 3rd party headphones.  I’ve always gotten it to work, but sometimes it takes a few tries before it finds its headphone friends.

You can play music without going into a running mode, so you can basically just use it as a wireless music player whenever you want, as seen below:


Once connected, you’ll see a headphone icon along the top of the screen:


You can increase/decrease the volume using the two +/- buttons.  Further, you can pause/resume the music using the middle button.  You can also long-hold the volume buttons to skip ahead/back on songs.


The music starts playing pretty much immediately, and then once GPS signal is found, it’ll audibly tell you that too.

While running (or riding I suppose – though that’s a bad idea safety-wise), I’ve found it best to wear the watch on the same side as the headphone transmitter.  In the case of the TomTom headphones, this is the left side.  This ensures consistent signal and reduces drops.  This behavior is similar for other GPS watches I’ve tested that have Bluetooth headphones.  Essentially, range is a bit limited.

In a left & left configuration, I’d rarely get music drop-outs while running.  About the only time would be if reached my left hand over to my right hand to do something (i.e. press buttons on another watch), I’d see a slight drop in audio for a moment before resuming.

Using the TomTom headphones, I found audio quality just fine (you’re running and breathing hard; this isn’t a concert hall with finely tuned audio characteristics).  I quite honestly can’t tell much of a difference while running between those headphones and the far more expensive options.


For 3rd party headphones, the TomTom Spark supports any Bluetooth audio device.  So it technically doesn’t have to be headphones, it could be a Bluetooth water bottle or Bluetooth speaker if you want.  But, they (and other readers) have found that certain brands implement the BT specification better (or worse) on various models.  TomTom has outlined all of those models here.


In my case, I picked up three different headphones.  I polled DCR followers on Twitter back two months ago on their favorite Bluetooth running headphones, and then picked up the two (very pricey) options.  I also then picked up a much cheaper ($20) option that was highly ranked on Amazon (like 2,000+ reviews) and suggested a few times by some readers:

Jaybird X2’s
PowerBeats2 Wireless
Mpow Swift BT4.0 Headphones

I’ve tried running with all three of these over the past 45 days, and all worked well.  All had good quality audio while running, and none dropped out any more than the TomTom units did (which was rare).


So why is a $20 pair just as good as a $170 pair?  Well, I think it’s partly just marketing and partly environmental.  If I were to sit in a quiet room listening to music, yes, the Beats and Jaybird sound better.  No question.  But, when I’m out running I’ve got my breathing, wind, traffic, and all assortment of other noise.  And just the fact that I’m not concentrating as much on the music quality anymore.  So it’s simply not as important.

Note my goal here isn’t a headphone review; I’m not really in that realm right now – so it was more validating they worked with the TomTom unit.  If I were to return them all, I’d probably just keep the TomTom ones.  They fit well (just as well as the expensive options), and the quality was good enough for me.

What is important though is that you find headphones that fit.  If they don’t fit then the experience and the quality will suck.  Most headphones come with various buds or wings that you can swap out to find your ear size.  It’s super important to do that.

But, all that said – unless you already have a pair of wireless headphones, I’d honestly just get the bundled TomTom version.  Mostly because you won’t have to worry about compatibility issues, and if there’s a problem – you have one chicken to choke: TomTom.  There won’t be any blame passing.

On capacity, the unit holds 3GB of music files.  It comes preloaded with a play list of 11 songs that actually aren’t too bad.  A bit of a running focused playlist.  If you have Spotify, I’ve created a Spotify playlist of the songs here to check out.

Finally – note that the audio capability does NOT work underwater.  Simply put, Bluetooth audio cannot transmit underwater, and since it’s transmitting via Bluetooth, that functionality just doesn’t work.

Mobile App & Website:


Obviously a big part of having a GPS watch is downloading that information for review afterwards.  For that, TomTom offers two methods.  First is via their desktop app that connects to your device via USB.  This will then upload the data to the TomTom MySports site, as well as to third party sites like Strava and RunKeeper.


You can configure a vast number of 3rd party sites, as well as saving to standard file formats like .GPX, .FIT, .CSV, and .TCX.  If your app doesn’t use one of these formats, you need a new app – as these are universally utilized.


These files will simply plop out into a desktop folder that you can upload to other services as you see fit.


Next up is the mobile app.  This allows you to pair your phone via Bluetooth Smart and then upload workouts to the MySports site.  Down the road, they’ll also setup backend connections to more 3rd party platforms so you don’t have to use the desktop uploader for all of those.

IMG_2858 IMG_2859 IMG_2860

While I wouldn’t categorize the mobile app as the most category leading, it does seem to get the job done.  You can view your activities pretty easily:

IMG_2862 IMG_2864 IMG_2863

And you can also view your steps, sleep, and related metrics.

IMG_2867 IMG_2865 IMG_2866

And for the most part, that’s it on the mobile app. Like I said, kinda bare bones, but ultimately it gets the core of things done.

Finally, we’ve got the website.  Over the last 6 or so months TomTom has completely rebuilt the website from the ground up.  It used to be that it was on MapMyFitness (platform), but now they’ve built what is basically a parallel version of that.  From there they’ll be able to build out new features (something they felt they were limited on within the MapMyFitness realm).

Right now though, things are still pretty basic.  To begin you’ve got your dashboard.  This shows you steps for the current week, as well as for the day.  It also below shows you all your activities and totals on the right side:


You can click on ‘Progress’ up top to get an overview of how much activity you’re doing, based on any of the different categories within the watch (i.e. cycling, running, general activity, etc…).


For most though, they’ll be cracking open an individual activity.  So back on the main dashboard you can click on any given activity to dive deeper into it.  Here’s one of my recent runs.

You’ll see it has summary metrics on the upper portion, and then splits along the left.


Down below there’s a graph that you can change/select the metrics for, by default it’s just pace and HR.


You can also select to show your HR zones for the run, which is a pretty nifty little graph:


In the event you’re doing a cycling activity, you’ll also get sensor information such as that from the cadence sensor.  You can see that listed below.  Also, you’ll see it for each split.


Finally, at the top of the page is the ‘Race this’ option, which allows you to race any given past activity, or some pre-created activities.  This isn’t an area I poked at too much, since my workouts tend to be different in length/function each day.

Still, if you were to click the ‘Race This’ activity, it would add it to the list on the second tab under ‘Training’:


It would then also show up on the watch as one of the items you could race.  Sorta like a Virtual Partner/Racer feature.

Finally, note that while I displayed everything in statute miles above, you can easily switch to metric (kilometers).

Product Comparison:

I’ve added the TomTom Spark into the product comparison database, so you can compare it against other models that I’ve reviewed or had hands-on time with.  For the purposes of below, I’ve compared the TomTom Cardio (previous edition) with the TomTom Spark, and then threw in the Garmin FR235.  That seems to be the unit most people are interested in comparing against.  But you can customize the tables as you see fit here.

Speaking of which, I’ll have my Garmin FR235 In-Depth Review out next week, so stay tuned for that.

Again, remember you can customize the above comparison charts with any of the products I’ve had hands-on time with.  You can do that here.



In general, the TomTom Spark is mostly the same GPS watch you know and love from previous incarnations.  It’s just that now it has activity tracking and wireless music playback support, with the music playback being the biggest differentiator to competitive units.

When it comes to the optical sensor, if I were a school teacher, I’d give it about a B+ for running, and about a ‘C’ for cycling.  I recognize that despite its cycling mode, I don’t think it’s that much targeted at cycling as it is running.  After all, its alternate name is the TomTom Runner 2 – not the TomTom Cyclist 2 or the Cardio 2.  On the running front, the only issues I saw were really in the first few minutes of the run, and really only in the last few weeks as the weather got cooler.

It’s somewhat funny – companies who release optical sensors during the summer months tend to ‘luck out’ for reviews, compared to those who release them in late fall or winter.  It may sound like a bit of a bad joke, but in reality it is absolutely a core challenge for wrist-based optical sensors, and would absolutely make a difference between tests, even on the same unit (for example, I saw zero issues in my hot/humid Mexico runs, or even my warmer Parisian weather runs).

Now while I’ve outlined many things that TomTom plans for the future, I’d caution that you should really only buy a watch based on what’s there today.  Or, in cases where a company is extremely reliable on adding new features they’ve marketed via official PR channels (meaning, they put it on paper somewhere).  Said differently: TomTom doesn’t have the greatest of track records at adding new features to GPS watches.  Sure they’ve done a couple of sprints for the Spark already – but I worry that many of the features they’ve described for the future may not appear.  So, instead of being disappointed down the road – simply make your purchasing decision based on what’s here today.  If they overachieve – great.  Simple, no?

The good news is that what’s here today is fairly compelling – especially if you want music integration.  There are exceedingly few GPS options in that arena that do stream music, and for me this one worked very well in that regard.

Found this review useful? Or just want a good deal? Here’s how:

Hopefully you found this review useful. At the end of the day, I’m an athlete just like you looking for the most detail possible on a new purchase – so my review is written from the standpoint of how I used the device. The reviews generally take a lot of hours to put together, so it’s a fair bit of work (and labor of love). As you probably noticed by looking below, I also take time to answer all the questions posted in the comments – and there’s quite a bit of detail in there as well.

I’ve partnered with Clever Training to offer all DC Rainmaker readers exclusive benefits on all products purchased. You can read more about the benefits of this partnership here. You can pickup the TomTom Spark or accessories through Clever Training using the link below. By doing so, you not only support the site (and all the work I do here) – but you also get to enjoy the significant partnership benefits that are just for DC Rainmaker readers. And, since this item is more than $75, you get free US shipping as well.

  1. Thanks for the review, Ray. Do you have any feel for if they’re going to make any significant software changes moving forwards?

    I use the TomTom Cardio as my “grab and run” watch and really have very few complaints – its basically the same watch with restrictions on it. The biggest ones are around the running “modes” though. As an example I want mile splits as a watch feature, not something that I have to “select” (that are then incompatible with interval warm-up/cool-downs).

    Having the downloaded files contain real splits would be good too – as it is, whenever you upload the file to TrainingPeaks (or similar) you get one huge segment. Their own website splits them out, but that’s about all it does. Its possible that that’s been fixed – I see the you had “beta” PC software – but it’d be really good to know before recommending this over the equivalent Garmin for holiday giving.

    One more random comment just in case they’re reading these comments and weighting them over their own support requests – (if so, hi TomTom guys) – only showing speed in MPH for intervals on the website is silly. Making it choosable would be better, but is there really any runner out there who uses intervals but wouldn’t prefer to see pace?

    • On the beta, it was just to get one of the firmware updates before it was released. That release was about 2-3 weeks ago now. So on the production versions since.

      As far as updates, I suspect we’ll see good progress on the web side, for the simple reason that them dual-paying probably isn’t something they want to do. So once they start cutting folks over and get comfy there, they’ll focus that team on new features.

      As far as the watch goes, I’m less optimistic on some of the advanced features making it. I think they could easily knock out stuff like auto-pause, but don’t think that HRV will come to light. Just my guess.

    • Frank

      Ray, I think your advice to considering purchase on the TomTom watch with what is available today and not what might arrive in the future is spot on. I say this as a purchaser of the last Multisport watch who was disappointed with how few of the promised (and published) upgrades were actually delivered. Auto-pause was one of them, so I wouldn’t be surprised if it didn’t make it to this generation either. That said, the functionality as initially delivered worked OK.

    • Graham R

      Or the Gym/Indoor cycling mode – Indoor cycling worked with the first MS 1.2 software, then they broke it, and never fixed it – Now if you ask on the forums about any of the old “planned” fixes they point you to the URL for the new product….

      interesting tactic, but yeah… 🙂

    • Rob

      Ray – Do you plan on doing a headphone review? I have struggled and failed to find a solid pair of bluetooth headphones that fit my ear.

      Thanks and great work as always.

    • I don’t plan one at the moment, mostly for the reason you noted around fit – which can be super-tough to narrow down from a review standpoint since everyone is so different.

      Also, it doesn’t help that I tend not to be a big wearer of headphones while running.

  2. Ben Pine

    Thanks for the review Ray! You said the battery life is 11 (?) variable hours. What is it with HR and music?

    • It’s super variable. I find that it’s horrible at the light + music + optical + GPS, down to about 2hrs. But just optical/GPS I’m able to do a weeks worth of workouts and activity tracking.

      Meant to add the backlight battery note in there…good call!

    • Frustratingly there also doesn’t appear to be a way to start a run in “nighttime” mode and then turn it off once the sun rises.

    • Yeah, I wish there was the manual option with a ‘Stays on’ setting like on a Garmin.

    • Ben Pine

      Thanks , I’ll probably hang on till they figure out graphene battery tech then.

    • Kellie

      Thanks for the review Ray. Just to clarify using the heart rate sensor only with workout modes (no GPS) your battery life lasted a few days?

    • Hello Ben, Kellie and all! To add to Ray’s response, here is a breakdown on what the battery life is designed to be: when using GPS only, it should last up to 11 hours. GPS + heart rate monitor is up to 9 hours, GPS + music + heart rate monitor up to 5 hours, activity tracking + music up to 6 hours, only activity tracking up to 3 weeks and clock mode only up to 6 weeks. Hope this helps!

    • Matt Anfang

      Ray, is it possible to use this TomTom spark in ultramarathons to keep it plugged it during a run or does it get disabled? Is there a way to bypass it to allow charging AND a concurrent workout like how you figured out that the vivoactive can do both? I called and technical support did not even know about that trick. 😉
      link to youtube.com

      Thanks for your help!

    • I don’t have one with me at the moment while travelling, but I’m 99% sure I tried it once before and it locked the screen & ended the activity.

      Perhaps someone else is able to double-check again. Note that if trying you need to ensure it’s not being plugged into a computer, since that will start the sync process. Versus something like a wall outlet/USB battery pack will give it just straight juice.

    • Matthew

      Screen locks out while charging whether in computer or in other charger.

    • Matt

      Thanks for the quick comments. That was the main reason why I bought the vivoactive over this tomtom. I’m trying to Boston Qualify but I’d also like to use it to run 100 milers. So unfortunately I had to buy another old Motoactive gps since I don’t like to bring my phone on runs for music and this nice light vivoactive for locking in my pace. I was going to experiment with the Moto 360 Sport but I read a lot of negative reviews so I was unsure if it was worth the gamble. Thanks again!

    • Matt

      Thanks Matthew!

    • Matt


      One last question, does the Garmin 230, 235, and 630 all have the ability to go from usb mode to garmin mode for a long ultramarathon auxiliary battery connection? I’m wondering if the audio prompts were worth it or if I just stick with my combo vivoactive + motoactive for the time being. 🙂

      Thanks again!

  3. Sagar

    Thanks for the review!

  4. Sean

    It’s still a bit baffling to me that TomTom refuses to spend the time to enable an open-water swim mode. Especially when this was advertised way back when as the first Multisport was released. I bought in on that note, and they’ve still refused to put it in. For that reason, I’m out. #sharktank

  5. Tommy

    Ray – Just a note, they have disabled the red LED sensor and are only using the green ones. I am not sure of the reasoning, perhaps not enough added accuracy for the battery usage?

    A big change from the older models is the addition of the indoor cycling and gym modes, which were sorely lacking on the Runner1 and MS models. This is a big highlight for me as it was a real miss on the old models. However, I am still scratching my head over features like auto laps, auto pause and other running basics that have been requested for 2+ years that still did not make it into this model. Perhaps they will come down the road, but as you pointed out they have a spotty track record for updates. They update a lot but it seems to be things that they want that the users don’t necessarily care about.

    Keep up the good work. I don’t make a purchase without checking with you first and the podcast is top of my list!

    • Very interesting on red led, I’ll find out details. It’s funny though, I had the red pick from late Sept and it came out so pretty, and my more recent pics were just green. But I’ve long found that taking photos of optical sensors is super tricky, so I just wrote it off to the wrong combo of camera lighting.

    • Jon Niehof

      It looks like the IR LED isn’t on, either. 😉

      (Only because you said “You can clearly see the different colored LED’s here.”)

    • Hello all, the red LED is not in use at the moment (since software version 1.1.14) as, to measure your heart rate, the red LED does not bring any benefit – it’s the green LEDs that do the hard work there. To save the battery consumption we’ve switched it off for now, and it has no effect at all on the accuracy of the heart rate measurement.

    • Jordie Lewis

      Hey there! Any word on when the TomTom Spark Cardio (GPS and optical sensor, no music) will be released? Thank you.

  6. Philippa

    Thanks for this great review Ray! I am still not sure whether I have made the “right” choice in terms of the TomTom Spark vs Garmin FR 235, but given that I already own the FR 220, I will lean towards trying the TomTom Spark and then getting a FR 235 down the road as a more “serious training” watch, or if we are lucky, perhaps Garmin may decide to manufacture a FR + music storage + BT playback – that would be the best of both worlds for me! 🙂 🙂

    I am honestly disappointed about the lack of interval alerts (vibrating etc), as this is something I really use in my FR 220, as well as the inability to plan workouts and download them to the watch. However, I think the TomTom Spark might be a great watch for relatively easy going runs where you don’t necessarily want or need a ton of stats.

    I look forward to reading your FR 235 review when it is out next week!

    Best wishes,

    • Philippa

      ps: any news on when the TomTom Spark HRM+earphone bundle (US$299) is shipping out? I already pre-ordered on CT (using your discount code – many thanks!) and just wondering when they might actually become available.

    • Sergio Melo - Brazil

      Is it true that this unit does not have interval alerts of any kind (ie vibrate, sound etc)? this is a deal breaker for me.

    • It does have alerts. It vibrates/beeps at the start/end of each set.

    • Richard Lawson

      No when you go into Run mode there is NONE, GOALS, INTERVALS, LAPS, ZONES & RACE. Selecting LAPS lets you pick an alert based on TIME, DISTANCE or MANUAL. So I use LAPS->DISTANCE set to 1km, and every 1km it vibrates/lights up and gives you the lap time. I think you can also get it to show the previous lap time on screen as one of the metrics, but haven’t fiddled with that yet while running.

  7. David

    Sorry. I haven’t read the whole article yet. Couldn’t stop chuckling at this:
    “That’s just the way I role.”
    I believe that’s actually the way you roll.

  8. Beth

    Thanks so much for the review. Did I miss it, or did you not have any input on battery life? In your initial look at the device (which I was reading last night), there were a lot of comments on battery life while running GPS and music and/or HRM. My biggest wish is to run with music and not have to take my phone, but I need it to do that for at least 5 hours (I’m a slow runner). Will this do it, or should I just wait?

    • Hi Beth, to answer your question, when running with GPS, music and heart rate monitor on at the same time, your battery life should be up to 5 hours. If you only run with GPS and heart rate monitor, but no music, then it will be up to 9 hours. With GPS and music, but no heart rate monitor, it’s still up to 5 hours. Cheers!

  9. Chris Watson

    Any idea why they aren’t doing ‘running cadence’ from the wrist?

    • Richard Lawson

      The cadence is recorded, and a summary is shown on MySports for each run e.g.: 170 strides/min, this summary is also exported to Endomondo. However if you get the app ttwatcher from link to github.com you can open the TTBIN file & export a TCX with the full cadence info!

  10. TonyT

    It is very logical that optical HR (from wrist) does not work well in cool weather. In order to work, this method requires blood flowing in the peripheral venous system. The issue is that body cuts peripheral venous flow (through contracting blood vessels in this area) in cold weather in order to maintain core temperature. Cycling is worse because hands do not do any work and the air flow cools down hands even more. Running might have issues too in sub-zero degrees weather.

    What I see interesting in Ray’s optical HR reviews (not only this but others too), that in MAX intervals > 180bpm, when the work quickly ends, the optical HR tends to follow actual HR very very slowly (remains at high HR longer). I’m not sure is it the issue in the algorithms, that could be worked out or physical phenomenon related to blood flow in the hands.

    To me optical HR seems to be ok, for normal running (in warm enough weather), but I’d leave it out for max interval workouts.

    • likepend1

      thx for the explanation Tony! “cycling cold hand”-flashback!!

      there’s lots of “limiting” factors when it comes to optical measurements!
      Temperature, light from outside (noise), skin color, hair, placement of the sensor (watch) on your wrist, …
      You always have to keep in mind that you’re moving away from the source you want to measure, your heart! And the arm is the 2nd worst point (besides the foot/ankle) for measuring the HR.
      The belt still is/will be the best way (place) to measure your HR. And it has been in the business for a long time 😛

      Don’t get me wrong, i’m still impressed how well those things perform, but the above mentioned points are keeping me from a purchase. Let’s wait what the future will hold …

    Best use of a rolling pin evar! BTW spotted a few typos etc…

    • Thanks. Randy is running trough my typos as we speak. I had to leave for a 6hr journey, so wanted to get it posted. I gave it a few read throughs, but alas Randy usually catches the many I miss.

  13. Mike S.

    Great review as always Ray.

    I have a few questions about music.

    1) Is it possible to have playlists? If so, how do you navigate through them during a workout?
    2) Can you only control playback through headphone controls?
    3) Is there a ‘shuffle’ mode?
    4) Is it fairly easy to upload music to the watch?
    5) How often did you get dropouts and how long do they last?

    Happy Thanksgiving (if you are celebrating it)!

    • Troy

      1. Yes there is playlists. If you use Itunes the playlists end up in your mysports tomtom app on your computer. There you can just push what playlist onto your watch.
      2. Playback is only through headphone controls.
      3. Yes there is a shuffle mode.
      4. Only difficulty was converting itunes library playlists export into xml. file. Why you have to do that I don’t know. One the the my sports tomtom see the playlists it is very simple to add and remove them to/from the watch.
      5, For me once I switched the unit to the side I had my receiver I don’t recall hardly any dropoutns on a 9 miler.

    • Asaf

      Hi Troy
      How did you make your Spark “see” the converted playlists?

  14. Gavin

    Thanks…Ray…as always, great review. I have 1 question about HR…the past Tomtom Runner Cardio didn’t use their HR info to calculate calories burned in a work out at all, do you know if that has changed with the Spark? I hope that makes sense…in other words, you would have your HR info and your estimated calories burned but the HR had no sway on estimated calories burned. My wife is eyeing the Spark, but estimated calories burned based on HR info is big for her so I just thought I’d check. Thanks for any info you can give me! Thanks again for your awesome reviews.

    • Tommy

      They still use MET tables to calculate calories for running, cycling and swimming. Freestyle and gym mode use HR based calculations. The problem is they use the same MET tables for indoor and outdoor cycling, when the have different MET values. Plus if you are using indoor cycling without a speed sensor you get no calories burned at all because it has no pace to compare to the MET table.

      I understand why they use METS since they have units with and without HR monitors, but I can’t understand why they can’t simply have it use HR if it detects HR data and METs if it does not (or make it a user option to use HR or METs).

      Ray – Has this ever come up in your discussions with TomTom?

    • Gavin

      Yeah, I figured it would be the same. This is a major fail IMO! Seriously…if they can allow HR to take over in Freestyle and Gym then it should be easy to do with Running, Cycling and Swimming. I think this will be a deal breaker for my wife unfortunately. She wants to see calculations based on her specific heart rate. Thanks for the response Tommy!

    • Hi Gavin, I’ll try to answer your question. As Tommy mentioned, at the moment, the TomTom Spark currently uses HR to measure calories in the Freestyle and Gym modes. In case we will expand this to other modes as well, we’ll make sure to let you know via our regular channels! At the moment, for other sports, the watch estimates calories based on the type of sport, your gender, weight and the intensity and duration of the exercise. I’ve made a note of your feedback and will pass it on to our development team as well. Thanks.

  15. Dr. Matt

    any hints re: FR235 optical sensor quality? I can’t wait….. 🙂

  16. Ken

    Thanks for the review. If I were looking at the watch only (no music, no HRM), would you give it or the Polar M400 the edge? Just looking at it for running/walking the dog and as an activity monitor, and I also want to be able to get the data (as easily as possible) to Map My Run and RunKeeper.

    • Mike S.

      My two cents.

      I’ve been happy with my M400. I just got a Scosche Rhythm+ HRM to pair to it. It has smartphone notifications and the app/website are good enough for me.

      You can export your workouts one at a time for importing to Strava and it seems to import everything, including HRM data.

      Although MapMyRun will import the data, it doesn’t show my route as far as I can tell. I’m not sure about Runkeeper either.

  17. Mike

    Having worn a vivoactive for the last year, it seems that TomTom has missed the boat by not including any smartphone integration. By including activity tracking, this sets the expectation is that this is 24×7 wearable. Nobody is generally going to wear 2 watches at a time, so they are forcing you to choose between smart watch and fitness watch. Moto 360 Sport from the Android Wear lineup looks interesting, but without an optical HRM may not capture much interest nowadays. The Garmin 235 with 24×7 heart rate monitoring, GPS and smartphone integration looks to be the most complete mix of features but is a little chunky for a day-to-day watch. For now I’ll stick with my vivoactive.

  18. MartinF

    Good review. The watch has so much potential, but not there for me yet. Problem is I keep comparing it to my 5 year old Motoactv still in use today. Audio alerts over the headphones to stay in a pace or HR zones, touch screen, and exporting splits properly to training sites are a must one you’ve grown used to them and very helpful. Why no power meter or ANT support?

    Everyone making a do all watch like this today should look at what was on the Motoactv in 2011 and start there. Add in proper waterproofing, swimming, slightly longer battery life, and great third party support with proper exporting. We really do need another Android based fitness watch or to tell Garmin to beef up their Vivoactive. Maybe this watch can gain a bit more through updates, but right now it’s just not there.

    • Daniel Sherman

      Couldn’t agree more. When it comes to training I still haven’t found anything that beats the Motoactv. One day…

  19. What is the battery life of the Tom Tom headphones?


  20. Pratham

    Thanks for the awesome review Ray. Waiting with baited breath for your Microsoft Band 2 review before pulling the trigger 🙂

    Two things to note for me

    1) Is there a link to the GPS + Cardio option that you listed. I did not need the music option, so saving some cash there would be great.

    2) There is a small typo in your Nov 14 run paragraph. In the sentence “That section is actually underground, so something weird stuff happens there.”. That should be “so sometimes” instead.

  21. Randy

    I’ve been using the watch for a few weeks, and most of my complaints center around the way they’ve handled music playback. I was coming from a MotoACTV, so perhaps my bar was set too high.

    Main complaints (which I posted on the first look post as well):

    -Only mode of playback seems to be “shuffle”. It’d be nice if I could pick my track from a list
    -Can’t pause or access any music controls or info on the watch once you’re running. I always end up pulling my headphones halfway out when I have to use the earbud controls; why not add a view that’s “music”? Every other conceivable view seems to be available. It’d be nice to figure out if I’m on episode 4 or 5 of my podcast without listening to the entire intro first.
    -Can’t resume a track from a previous run. No bueno for audiobooks or podcasts. Also can’t fastforward, so far as I can tell. Gotta start over, every time.

    If you just want to shuffle music while you run, it works fine. Anything else is a bit of a challenge.

    Finally, their Android app has some major issues. The Play store and the TomTom forums are littered with bad reviews and problem reports citing dropouts when trying to upload workouts. The best solution is to add the watch as a “trusted device” is you’re using a newer build of Android. You may have to do some factory resets of the watch and re-pair multiple times as well. Mine finally syncs, but it took a lot of headaches to get it working consistently. Even then, it’s not automatic. (Unlike, say, the MotoACTV, which just does it over wifi when I get home.)

    Any chance these things get changed? Alternately, can someone just give me a MotoACTV 2.0 (with an optical HRM built in)?

    • JR

      Shuffle mode only would be a dealbreaker for me, as I primarily listen to audiobooks while running.

    • Thomas

      Could you give me some more details on the way the music player works? You say it plays in shuffle mode only. Does this mean that if I make a playlist of songs, it just shuffles through the playlist and it can’t play the songs in order? I was thinking of making a playlist from chapters of an audiobook, but if this is true it won’t even play those chapters in the right order…

  22. noseat

    I’m not known for grammar but this doesn’t sound correct:
    “My testing has been on a mix of both of those units, and in the following this review I’ll return the media loaner to TomTom like normal.”

  23. Jason

    Thanks, Ray! Disappointed they didn’t add many new features besides the music and activity tracker. If you had to pick for a runner who doesn’t cycle, would you mean towards the spark cardio w/o music ($200), fr225 ($220-250) or save a little and go with the cardio runner.

    I’m also considering getting the 220 ($150-$164) and picking up a scosche rhythm plus later on.


  24. Matt

    Thanks for the great review, Ray. I’m intrigued by this watch because I like the music features. But I have to run with my phone for other reasons, and I already have a tickr x, so I just can’t see making this purchase or any watch purchase right now, except for perhaps the swim features. But even then, the Black Friday deals are making the garmin 920 xt in the ball park. That seems like overkill for someone like me, but it seems to have a better “just works” factor. Thanks again for all your work.

  25. Jimmy Stevenson

    “Said differently: TomTom doesn’t have the greatest of track records at adding new features to GPS watches. Sure they’ve done a couple of sprints for the Spark already – but I worry that many of the features they’ve described for the future may not appear.”

    So true, one of these new features I heard about was the multisport option for the previous multisport watch. To be fair, I never read anything where TomTom said that it was a future enhancement, just something they were looking at as an option. I still like my watch, just hope that someday they will add a true multisport option to be more competitive with the likes of Garmin and Polar.

  26. Nicholas

    Was it ever mentioned how the backlight is turned off or on and options regarding it? I didn’t see it in the review.

    • Mike Lin

      Cover the screen with your palm for a second or two to activate the backlight. Or turn on the night mode which leaves it on all the time, but as noted above it burns the battery. I wish there was a setting that triggers the backlight on button presses, like Garmin.

  27. JR

    How well does the manual lap function work? Do raindrops trigger it like in the previous Cardio Runner?

    • Hi JR, the manual lap function on the Spark should be less sensitive to rain drops than its predecessor since we now have two sensors to trigger laps and back light, on opposite sides of the screen, instead of only one. This means rain drops would need to hit both points at the same time, which is less likely than when there was only one sensor. Hope this helps clarify your question!

  28. Guymac

    Thanks for the review, will definitely consider this next to the FR235.
    Does it have a ‘current’ HR mode, w/out starting some kind of workout? Also, I’d love to see what the HR activity graph looks like! Will check your TomTom Cardio review to get an idea….

  29. Senior Serious

    I never understand the fixation on current pace by runners. It makes no sense, you are a human not a robot trying to achieve a fixed pace. Not to mention the usual lag and it’s never, ever going to be a useful metric. Yet a ton of people…mostly newbies and hobby joggers whine about this the most. I used Avg Pace and call it good.

    How is the Vibration alert? I found the the TomTom Runner had the best vibration alter of any of the watches out there to date. I hope they didn’t change that.

    • It’s still pretty good, I had no issues with feeling it (for example, as a trigger to start an interval).

      While I think instant-pace is less valuable than some make it out to be, I think avg pace is at the opposite spectrum as well. I personally prefer a lap-pace as the best way to pace.

    • Bill L

      I couldn’t agree more re: current/instant pace. I take 30+ people on runs up to 20 miles, and EVERYONE has a different current pace. Many come up to the front to complain that their Garmin says our pace is too (insert fast or slow). Interestingly, the average pace works out to be pretty close. I think it may be because humans simply are too slow running to cover enough distance between readings to not have measurement errors show up. I imagine whether your arm was swinging forward or backward as being enough to influence the reading. Maybe not. I don’t know the actual process involved with measuring instant pace. Nevertheless, I also display at all 3 metrics you mention: current/instant pace, lap pace, and average pace. I am called upon to deliver an average pace but find lap pace to be the more significant for what I’d doing right now. That’s true for all the brands I’ve used.

    • Nighthawk700

      “I never understand the fixation on current pace by runners. Yet a ton of people…mostly newbies and hobby joggers whine about this the most.”

      I can only speak for myself, as a newbie runner. I have a bad habit of starting off my runs too fast, and thus running out of steam before the end of the run. Therefore I look at my current pace to see if I’m going faster than I should be. As I get more experience, I’m starting to get a better handle on it, but until then, something that can instantly tell me if I’m going too fast is useful. Right now I have my phone (Endomondo) set for 2 minute lap times so I’ll get a better reading every two minutes than I get with the “current pace” number.

    • raven

      I have come to prefer lap pace and split lap pace defining a lap as a kilometer, but I also greatly prefer getting pace (and cadence) from a footpad rather than from the wrist accelerometer or from GPS. The latter two are not completely horrible, but if one gives a high priority to pace than I’d suggest they should have a footpad and properly calibrate it.

      So of course, the TomTom units don’t support footpods. Sigh.

    • Troy

      Thanks for this info. This is my first GPS watch and just got it this week. Was frustrated with my first several runs because I wasn’t getting my audio prompts like when using a phone app. Just ran today and was able to see my pace for a certain distance. Again thanks because without that workaround it might have been a deal breaker for me. The buzzing and lighting up of the watch works great or at least similar to the audio prompt from the phone app.

    • Nancy

      Thanks for the comment. Am I to understand the watch doesn’t provide audio prompts of distance or time splits when in use? Is this the case for all running modes or just some?
      I just ordered this watch and I’m worried about not getting prompts as I go.

  30. Brianf

    Ray, I am interested in knowing if Tom Tom has any plans to support the Stryd running power meter? I would consider it if they would provide Stryd support in run mode. I would very very likely purchase if they provided power zone alerts via bluetooth. Cheers.

    • I’ll inquire, but I honestly doubt it. I’d think they’d support cycling power meters first (much wider audience), but I don’t get the impression that’s their target market.

  31. Brody

    I guess I could stop being lazy and go look it up but I didn’t see you mention the memory the watch has allocated for music storage. Set amount or different options?

  32. S-Go

    Hi Ray, thanks for the review. The TomTom’s a good idea of the direction sports watches are going to go. However, I spotted the Suunto Traverse in your pictures and was wondering when we could expect your take on it.

    I might be looking to replace an Ambit 2S soon and I’d like another Suunto. Even just a first impression of the Traverse. would be welcome.

  33. Nice review with great details…have only one question if i understood correct garmin FR235 does 11 days of battery life with activity recording which include HR recording as well. which means it capture sleep data based on HR as well.

    Can you confirm above and how does spark works?

    • The Spark doesn’t measure HR 24×7, so no mode there. They’re talking about it, but that’s it. It does measure sleep, but just total hours – nothing like deep sleep/etc…

      As for the FR235, it does do HR 24×7, as well as more advanced sleep metrics. However, Garmin’s battery claims of 11 days are super-optimistic. I’m getting about 2.25-2.5 days per full charge, assuming 1hr of GPS workout time per day. So, about 25% of claimed battery life.

    • Darren

      Woah! That has to be a hardware issue and not a marketing-vs-reality issue, right? Let us hope.

    • Luigi

      Are they planning to improve the sleep metrics tracking?

  34. Tim Mifsud

    I know it’s probably not your realm, but sports headphones are quite the tool for a number of fitness people. I’ve got x2 and Aftershokz Bluez2. Both are good. I’d love for you to check out the Aftershokz Trekz Titanium when it comes out as I’m interested. I used the Bluez 2 version1 until they died from sweat ingress. I used them cycling quite safely as they don’t block the ears. I’d be interested to know if they work with the TomTom Spark. Love your work.

    • Mike S.

      Interesting. Thanks for the tip.

      Have you had any problems with dropouts? I had a pair of Jlab Epic BT headphones that I returned because of constant dropouts. It seemed to be related to my Polar M400 also being paired to my iPhone 5.

    • Tim Mifsud

      Hi Mike S.

      It did occasionally drop out, but that was mostly due to sweat ingress. I did notice the occasional dropout for like a second here or there if passing certain areas where there were lots of strong wireless signals going by in a similar broadcasting frequency. Otherwise, audio delivery was quite solid. It had a really long range too; At least 15 metres from the broadcasting device.

  35. Tim Mifsud

    I’ll clarify, I don’t work for not am I affiliated with Aftershokz. They just happen to have the best product in my opinion for taking phone calls without having to stop my ride, listening to music while being able to hear the traffic, and can be controlled from my Magellan Cyclo505. They are great when they worked. I’m pissed that after 12 months of solid use, and $120 Aussie dollars they have died and now do not last more than 15mins before they become non-responsive. Company response was they are out of warranty and can’t be replaced under warranty. Pretty annoyed at that response, hence my interest in the next product and their claim for greater sweat resistance. I highly recommend you try them Ray as you could take calls while riding or running and product testing. You could even use them to take voice notes for your reviews while testing other products. Just a thought to help you out.

  36. Faris

    Good review as always ray.. but how accurate the HR during gym work or cross fit?

    • For better or worse, I’m not really a cross-fit person, so can’t say there unfortunately. Perhaps a few readers can weigh in.

    • Tommy

      Gym mode is a bit hit or miss honestly, but I think that may be more of a function of the technology than the watch itself (although it may be how they have implemented). On activities that requires a lot of forearm tension and flexion it seems to struggle as those movements contract the blood vessels in the forearm so it reads it as a reduced HR at times. Is it a material difference? Probably not. I have worn multiple HR straps during weight training workouts and even though there is some variation within the activities, they generally hit about the same overall average. I might not have even noticed the difference if I was not wearing two different HR monitors for comparative purposes.

  37. Richard

    I am histiorically a smart phone runner (if you understand) and it definitely appealed for the ability to go phone free (I like listening to music)

    however I like an audio update each K as to pace/speed, and it does not do that

    It also has known issues with certain headphones depending on which arm the watch is worn on, which feels pretty rubbish really, my own (admittedly very cheap headphones) would not work on left aarm, but would on right

    I’m waiting for the moto sport and hoping that will meet my requirements.

    thanks for the review

    • To be fair, most wireless headphones are finicky when it comes to cross-body wearing. I’ve seen that on other devices (Adidas for example), as well as phone use, depending on where exactly I wear it. The challenge is companies try to minimize battery consumption as much as possible, given the tiny batteries – which hits strength of transmission.

  38. Pedro Lobo


    Another good review, thanks! 😉
    One question about the straps. I really like the blue strap, witch is a large strap. But I have a small size wrist(155cm), I wonder if it fits nicely, and if it doesn’t get too lose.
    Can you advise on this?

    • Pedro Lobo

      Ups…155mm! 🙂

    • Mike Lin

      Probably not. I have a 190mm wrist and I’m within 20mm of the very smallest hole on the large strap.

    • Hi Pedro, there’s a way for you to measure which strap fits you best. The small strap fits a wrist size between 121-175 mm and the large one any wrist that measures between 143-206 mm. There’ll also be plenty of colours to choose from. The colours that the watch comes in are black and purple haze for the small size and black and ale brown for large. You can also purchase straps in other colours separately, like green, orange, blue, pink, grey and/or combinations, depending on the strap size.

    • RA

      Where Could we buy straps for this new phone?

  39. Nathan Budd

    Hi Ray,

    The cycling part of this review has spiked my interest. I already have a Garmin Edge 520, and was looking at purchasing a Forerunner 235 for running, which I was also going to use as my HR monitor in broadcast mode whilst cycling.

    Your review mentions that optical sensors aren’t very useful when cycling. Is this likely to be the case for the 235, or is it simply down to the Apple Watch, Fitbit and Samsung Gear fit having lesser optical sensors?

    Apologies for discussing Garmin in a TomTom review, but it’s sort of related.

  40. a_circelli

    so a 199$ multisport watch with optical heart rate is super competitive against Garmin! I don’t care about music; FR 235 is 329$ with some extra features but also an extra of 130$! I can’t undestand Garmin prices policy… Now in Europe ) 920xt is 469 E without heart rate. Tom tom cardio (runner 1) was 249, now runner 2 is 199 (without music). Instead, vivoactive is 249$

    • Jason

      yeah but you can get the Forerunner 225 for $250 right now. I would argue that the 225 has more features than the $199 spark cardio (except cycling), and the 235 has even more features than that (several features that only the 620 used to have). The spark didn’t add many additional features except for music and activity tracking. The 235 has many, many new features (see Ray’s post about it and the 630). Not to mention that the Garmin website is better. So, if you consider those things, I’d say the price is about right. I’m not sure I would spend $330 on the 235, but it depends on what you’re looking for.

      Also, is the $199 spark Cardio even a real thing? Haven’t seen that version anywhere yet.

    • Dan

      Correct me if I’m wrong, The spark has a gym mode which I can use with HR and calories. FR225 doesn’t have that.

    • Jason

      True, you can only upload activities as runs on the 225. From a purely running standpoint 225 seems better to me, but the spark is perhaps a more well-rounded product.

    • Troy

      Not to mention you can get it at a discount far easier than a Garmin product. Ended up getting 20% off from backcountry.com bringing my total to $199 for the everything watch. That is $130 less then I can get the Garmin 235 right now which is a significant difference. ALthough I think I would like some of the features on the Garmin. Being a $130 cheaper at this point and having music this is a great buy specially for a first time GPS watch owner like myself.

    • Jason

      I decided I probably wouldn’t use the music feature much and if I want music, I will just use my phone. Think I’ve settled on FR220 for $150 + Scosche ($64 w/ a coupon code). One feature that I really want is the lap pace, which isn’t on the TomTom. Also, I look forward to the personal records. Since I just started running ~6 months ago, I hope that I will be setting PR’s fairly often in the coming year :).

      But that’s definitely a great deal on the Spark, hope you like it!

  41. Brody

    Great review!

    Question, I had an earlier model and found when I wore it I would bump the “joystick” thingy and change screens or hit enter. Did you have that problem or have they changed the ergonomics or the amount of force it takes activate the buttons?

    Thanks again!

    • I haven’t see any issues there. In fact, almost the opposite – it’s often slow to respond to presses.

    • Brody

      Thanks to the replies and clarification on both questions I had.

      Side note that I don’t know where to add… I am having issues with your new ad system when browsing on my phone, my method of choice. I don’t mind the pop up or redirect but I am normally getting a blank page and it’s not coming back to your site. Hopefully it’s just me and not happing to multiple people.

    • Hmm, very odd on the ads – hadn’t seen that reported yet. Let me know if you see it again. 🙁

  42. burgess eberhardt

    Ray, (or anyone else)
    Have you used an optical heart rate sensor device while cross country or downhill skiing? I’m curious about the problems heart rate sensors demonstrate in cold weather.

    Thanks for another fine review!

    • Not cross-country skiing, thought I think I may have done one optical last year downhill skiing. I’ve used the Scosche many times downhill skiing without issue (on upper arm, below clothes).

      That said, the last week I’ve spent in cold sub-0*C weather up north in the Arctic Circle. So lots of fun testing optical sensors.

  43. Ela

    Again a very good review, thanks for that!
    I’m running with the older model, the tomtom multisport cardio. Yes, there’s a lack of updates and i don’t think that there will come more in the future. although i would love to have some more options like for example autopause. The tomtom forum is full of wishes 😉

    What i’d like to know is whether the wristband from the spark fits also to the unit from the multisport cardio. Would be great to have a smaller wristband!

  44. Dan

    Great review Ray. Additionally, have you try the accuracy of the gym mode? How’s the HR and calories compared to an old styled chest strap?

  45. Jason

    Ray, did you not have a chance to try out the treadmill accuracy? I’m assuming it’s not been improved any since they didn’t change much on the watch at all besides music and the activity tracker.

    I see in the comparison that the Spark does not have personal records, but does anyone know if the website has them?

  46. Patrick

    Thanks for this review Ray.

    Quick question for you or others. I’m still using a Garmin FR10 and want to upgrade to include heart rate. My price range is $225-$250 (usd) and I’m down to the FR620 with hr strap or TomTom Spark. Between the two the 620 is a no-brainer, right?

    • Jason

      620 is definitely a better deal imo. However, I can’t see myself putting on the chest strap for every run, optical is just more convenient.

    • Afzal

      I am also deciding between the Garmin 620 and the Tom Tom Runner 2 Cardio. The Garmin 620 is an old model but seems to have more features than the Tom Tom Runner 2 Cardio. However Ray indicated that the Tom Tom Runner might have firmware updates that will then offer more running dynamics data. In light it this, is it wise to buy the Garmin 620. Note the Garmin 620 is discounted by around 40% and is now sold for 33% more than the Tom Tom Runner 2 Cardio. I am in South Africa

    • Where did Ray indicate that? The TomTom Spark has no sensors for running dynamics metrics other than cadence. TomTom doesn’t make or sell a chest strap HRM that tracks running dynamics data, and won’t work with something like the Garmin HRM-Run or the Wahoo TICKR RUN.

      No amount of firmware updates alone can give the TomTom Spark running dynamics related capabilities.

    Hey Ray,

    Thanks for the review.

    How do you like the button controller on the watch? Is it fairly easy to use? A better idea than separate buttons or a touchscreen?

  48. RETH

    I find watch based optical sensors very impractical when training in cold or inclement weather where I typically where my watch on the outside of of my outerwear. Who really wants to pull up their sleeve to check their stats when it’s extremely cold or raining? Love my Scosche.

    • KAP

      you can have a “window” on your shirt wrist area 🙂 It doesn’t need to be too big and can be through a transparent cloth, may be a 3M reflecting cloth stitched ? .. If you see tomtom commercial, they clearly mentioned that HR monitoring works better if you do some what warm up prior to running. I guess this is because of similar concern that you/most of us have. If you wear the watch on top of your outer wear, I am afraid, it may not even work (HR monitoring) !!

  49. Martin

    I’ve had lots of problems with my Runner 2 Cardio + Music and have sent it back for a refund. I suspect I had an early production model with some hardware glitches as I’ve not seen anyone else complaining (mine kept crashing half way through a run). I didn’t go for a replacement as I’d really lost confidence in TomTom plus was frankly underwhelmed by the Runner 2. My previous watch (now current again) was a Nike Sportswatch “powered” by TomTom. On the assumption that TomTom wrote the software for the Nike watch then they seem to have left out many of the good features eg tap to lap and then showing details of the lap. The music side of things worked ok but need the watch to be on the same side as the headphone bluetooth antenna to avoid drop out. The heart rate sensor worked fine for me and in general seem less prone to spikes than the polar strap I wore with the Nike. I did like that I could upload direct to Strava but the TomTom site itself was very poor. The activity and sleep tracking really do seem like an afterthought just to say they do activity tracking. Have put in an order for FR235 so will see how that pans out.

    • Anna

      Hi Martin, similar story to me, I am sending my Runner 2 back and about to replace with a FR235. Not sure if you also experienced this but I found the average pace / current pace to be incredibly inaccurate when using the runner 2 on running mode.

  50. Jemma

    Thanks heaps for the review! I really appreciate how thorough you are.
    I’m super excited to buy one now. I’m going to get the Jabra Sport Rox earphones to go with it as well.
    Hopefully TomTom do follow through with their promised updates, but either way the watch has all the features I am currently looking for. 🙂

  51. Jamie Duguid

    Does the Spark have smart phone notifications?
    Your table says it does but it isn’t mentioned anywhere else in the review, or in other reviews.

  52. Tyler

    I know you said you weren’t doing head phone reviews, but did you wear the $20 Mpow’s long enough to gauge comfort/ability to stay put while running, and sweat-proofness.
    Have yet to find sweat-proof earbuds that’ll survive more than a month or two.

  53. James

    Will a long sleeve over the watch affect the GPS performance? Like my cold weather running tops that hang down over my wrists; I have always just pulled them up for a second when I wanted to check my regular watch, or I have worn a watch over the sleeve, but since this has a HRM that needs to be in contact with my skin, that won’t be an option. Does it need to be both in contact with my skin and uncovered? Thanks.

  54. Steven Griffin

    Appreciate your articles.

    I’ve used the multisport for 16 months. My old eyes appreciate the interface. I wish the online tracking was more helpful. Something similar to trainer road would be helpful. On the hardware side, my right button failed after last week’s swim. Since the warranty is 1 year, I am glad that I purchased the extended warranty from a supplier on amazon. Hope to have fixed and back on my wrist next week. I swim 3 to 4 times a week and assume that the water proof seal is not robust enough to last longer than 1.5 years for many users so I’d at least buy the extended warranty.

  55. Jaime Barillas

    Definitively was waiting for this in-depth review. Thanks!.
    I’ve been waiting for a GPS watch for running with vibration alerts and the ability to store music.
    If it had the ability to cue distance, pace, etc. through the bluetooth headset will be perfect to completely leave the phone at home.

    It looks like it is not compatible to ANT+ HRM straps, right?. I didn’t want to pre-order the one with optical HRM, and I was hoping to use my existing Garmin strap.

  56. Asaf

    Hi Ray
    Maybe you know this one:
    Can you set mutliple zone limit/alert? For example, vibrate once out of zone 2 AND 3?

    • Hi Asaf, what you’re able to do is set a specific zone – for example to vibrate once you are out of zone 2, OR of zone 3. It can’t however vibrate once out of each zone – so the answer is OR instead of AND. Thanks!

    • Asaf

      Thanks for your reply! Perhaps I didn’t phrase my question correctly. I just want to know my heart rate is not too high (staying out of zone 5). Can the watch help with this matter? If I have to specify one zone only as a range, then I’ll get vibration alert when my heart rate is too low, which I care less for.

    • Hi Asaf, I see, thanks for the clarification. Yes, there is a way for you to do that. You can select to train in a specific HR zone (let’s say zone 4), or also set up a custom heart rate zone (where you choose a minimum and a maximum BPM). You will then receive alerts to tell you if you are in your zone or outside of it (also specifying above or below), which will also be shown visually on the watch screen.

  57. Rob

    Hey Ray(and community),
    As a 2year multisport cardio user I warn everybody about a total ignorance of the manufacturer once the product is out and selling. Don’t take me for my word. Go checking the support forum on your own. Like here:
    link to en.discussions.tomtom.com
    Forget about any reasonable updates or features.
    The watch is NOT a “grab and run” but rather a “connect to a PC if you want to go running later that day”. The quick GPS fix file expires in 2-3 days max. The blutooth connection takes forever to use and forget about Windows7x64ult(no support).
    The watch lacks sporting essential features like the Autopause….and many others easily implemented by other brands. After 2 years of complaints they add the MP3 player!!!! Just try to count how many of the requested features they did implement: ZERO. OK, listening to customers is not an obligation-fair enough. So let’s count how many features originally promised by the manufacturer have been implemented in the updates: ZERO. The forum is full of BUG reports and minor reasonable feature requests-never even taken seriously by the brand.
    TOMTOM wants to make easy money on the wearable wave of the market. They have never been a fitness brand. Get used to it. The only reason why they changed the HR sensor is its price. They just want all of the Myo margin for themselves. The future promises about new features thanks to the new sensor are straight lies for some of them are technically not possible to do with optical sensor of any source at all.
    The UI is outdated(4years old-no change) and not very friendly. The system is sealed against any enthusiast developer’s will to experiment.
    Maybe Garmin or Suunto are also far from ideal but I want to give them a chance. Tomtom got one but obviously all they wanted was the $300. Never again.
    I am looking forward to the Forerunner 235 review. It looks like the better choice as far as the reviews go.

  58. Phil

    My old Nike/Tomtom Sportwatch is getting close to biting it and I’m looking at getting a replacement, but I’d like to keep the lap information I’m used to seeing when doing intervals/repeats.

    What information is given at the completion of a lap?
    Can I access lap history on the device?

    The old Tomtom was missing quite a bit of this, and I was curious if it had improved any this iteration.

    • SS76

      This is what is holding me back, thanks for writing this. The app right now sucks, I want to see it update before I commit to the Tom Tom spark cardio +. I too am looking at the Garmin forerunner F235 however the music capabilities of the spark is a big draw for me.

  59. Jordie Lewis

    Hey Ray! Thanks for the review. Quick question: Did you get the Spark connected to the Scosche Rhythm Plus? I’d like the pick up the GPS only version and use it with the Rhythm Plus. Thank you.

  60. Joel Roth

    I bought my first GPS watch Black Friday 5 years ago – a Garmin Forerunner 410. Although I run and bike occasionally, the thing I use the watch for the most is I do quite a bit of soccer refereeing. Last year, I bought a Polar M400. The first thing I noticed is that the total miles on the 410 was 33 to 50% higher than on the M400. So, I had refereed over 200 games at this point thinking that I had run a certain number of miles and now realizing I was possibly way off. I’m assuming that with the SMART recording vs. 1 sec. intervals, the M400 is more accurate. Also, I used a phone a couple of times and it tracked closer to the M400. With refereeing, I’m of course going back and forth in a fairly small area, so I think I need the frequent intervals. In any case, even though I’ve only had it a year, I’m thinking of changing again. After reading your reviews, I think I’m leaning towards the TomTom Spark or possibly the Forerunner 235. Thank you for your great reviews and information.

    • KTS

      Hi, what did you do in the end? did you go for the TomTom?
      I’m in the market… looking to treat myself.. i’ve narrowed it down to the M400 and the new TomTom Runner 2 Cardio… i run a few times a week and use my smartphone for music and i use sportstracker which i like… but i want to get a watch i can use for daily activity also…

      i’d be interested to see what you changed from M400 to as i cant decide…

    • Joel Roth

      As of now, I decided to stick to the M400. I decided that the things that were annoying me weren’t enough to upgrade when it still does what I want, particularly now that notifications from Androids was finally released. I’m still a bit perplexed that the Forerunner 410 had almost 50% higher miles of running (when refereeing) than the Polar.

  61. Angel

    Can you get audio cues such as pace and distance through Bluetooth? Using the headphones with that set they wouldn’t last 4 1/2 hours? Also with GPS and music is there a chance it could die before 4 1/2 hours? I’m doing my first marathon next summer and would hate for it to die at the end.

    • Mike Lin

      There are some audio cues – HR zone, etc. but surprisingly not pace and distance. I find the manufacturer’s battery rating is best case for brand new device. There are a few tricks to help, like leaving the watch on the charger until the last minute and not turning on the GPS and BT until the very last minute before the race starts. In your specific situation, I’d say it’s borderline for a 4:30 marathon. Also, check that your headphones can last that long too!

  62. great review – many thanks
    i want it for indoor rowing, so presumably would use indoor cycling mode
    bit concerned that hr is less reliable for cycling than running. wonder if that’s because one is gripping the handlebars -in whihc case may be flaky for rowing as well
    intend to give myself early Xmas present and will report back

    any special relationships in UK? as with amazon US etc. sadly it is £s=$s pricewise – as usual

  63. Jeff

    I’m really confused about which version of the TomTom’s have an optical heart sensor. Looking for the least expensive GPS watch with one.

    • Hi Jeff, to add to what Ray and Diana mentioned, the Spark starts with its basic version, which includes GPS, 24/7 activity tracking and multi-sport modes. The next step is adding either music or cardio (line-up may depend on country) and the high end model has both music and cardio. Hope this clarifies your question. The bottom line is that if you are looking for the optical heart rate sensor, this will be mentioned in the watch name (e.g. TomTom Spark Cardio + Music) and on the box.

  64. Monica

    Thanks, great review!
    I just wondered why the older multi sports model is more expensive than the spark/ runner 2 model on certain sites, e.g. Amazon…

  65. ay

    Thanks Ray for another top notch review.

    I originally bought the Multi-sport after reading many of your other reviews and I’m relatively happy with my purchase and being my 1st main running watch its done as much as I ‘roughly’ expected. Given this new model I’d be reluctant at present to purchase this new version whilst mine still runs perfectly which is good as shows the original watch lasts well.

    What has let it down though as others have stated on this thread and the initial review was the lack of comms from TomTom on software/watch updates being released on their main forum – mostly the virtual racer and lack of ability to customise your own race (only 5 defined races and you need to actually run a race before you can update a new one with no auto facility – very poor). This proposed update has been on-going for well over a year as a mega flaw in the watch and I don’t think this new one has this facility either. So couple of quick questions to aid me please –
    1. Am I correct in think no improvements in race modes on this new watch?
    2. I like my Multisport other than this so can you advise a low budget watch that has a good race mode facility where you can set distance and target finish time to pace you?

    Since TomTom Community Mgr is making appearance a quick question –
    1. On your forum for over a year the virtual racer/pacer has repeatedly been requested and limited response but I note ‘Julian’ has now stated it will be a facility added to watch – timescales for this update?


  66. diana

    really would have liked to see comparison betweenn fitbit surge and tomtom spark cardio
    incline to tomtom BUT
    does fitbit have any major advantage?
    not interested in garmin as have iphone that does not do ant so need bt samrt
    nb for those who want hrv, the ithlete hr app [about £7 in UK] on iphone should pick up the hr from the tomtom watch. works very well with polar h7 chest band transmitting bluetooth smart. it may be different for real athletes, but my am hrv does not predict my pm performance, but hrv surely knows when i have a cold

    • DougM

      Hi Diana, I’m a rower too (just indoor at the moment), but do a lot of running too. More running presently. First, I just returned a Fitbit Surge. I found the GPS to be prone to occasional huge errors, didn’t like that it wasn’t water resistant at all (Don’t need depth, but would find it fun for windsurfing.), and most of all, found the HRM wildly inaccurate. I tried shaving my arm, sealing the device in duct tape, sliding it up my arm as far as the large wristband would allow, and found it useless, unless I nearly sat still (Some call it a “Sitbit”.). I will probably try out the Spark+Cardio+Music. I find the music feature downright seductive, it’s waterproof, and so far it seems to get the best ratings of all optical HR sensors. Having said that, I’m scared to death about the HRM reliability (the great graphs above notwithstanding), since the technology is very similar. I’ve learned much from this review, and the comments, and my own experience with Surge. The coldness problem makes sense if one allows themselves to get cold, constricting their capillaries. Seems to me a good strategy is to get a good warm-up first, and then dress to stay sufficiently warm. As for us rowers, another issue may be the wrist side to side articulation. If one nudges the watch into different positions continually, I can see how the sensor would reasonably have problems. I plan to always wear a wrist sweatband distal to the watch, keeping it away from the wrist joint, and blocking some leakage daylight. I did find that the Surge worked better this way, though not sufficiently. I’ll feel I’ve been fooled twice if I find the Spark no more reliable in HRM. But what seals the deal with me is that it is also compatible with a smart Bluetooth HR strap. That’s my backstop. I can envision using the strap if needed for very serious training, and getting by with a so-so optical sensor the rest of the time, if need be. Hope it’s not the case, or that there’s some continuous improvement with the algorithms, but we’ll see. Wish me luck.

  67. GMRO

    Thanks for another great review. BUT I notice that in a few of your latest “in depth” reviews you don’t test the units on a treadmill. Due to weather in PA/USA I have to run on a treadmill approx. 4 to 5 months of the year. SO for me this data, that is if it’s accurate or allows you to tweak the data – tune it if you will, is important.

    Any reason why you don’t do the treadmill run tests these days?


    • Sometimes I fit in treadmill runs, sometimes not. Really just depends on timing. For example, I did actually do one on the FR235, but didn’t include it in the review. I may try and go back and update the review to include it.

      The TomTom Spark does not allow you to tweak it, nor to pair to a footpod (unfortunately).

    • GMRO

      Thanks for the feedback Ray! A;ways enjoy your info…

      I guess at this point I’m swaying towards the Garmin 235…maybe. Though the HR is important to me. I’ve nothing but my ol’nike GPS sportswatch. It’s seeing lots of wear and I think it’s time to upgrade.

      My list of wish’s:
      Optical HR with accuracy.
      Treadmill accuracy, don’t care if I need a pod or not. As long as the internal acclmtr can do the job.
      Uploads my runs to nike+ site.

      Again many thanks for the work/testing you provide!

  68. Angel

    I’m seeig the Spark listed in a color with black. is there a difference in thickness between this and just a black band?

  69. Phil

    What information does the watch display at each lap completion, and can I view lap times in history on the device? For the interval work I do, I found it limiting that the original Runner didn’t have much in that area.

  70. YLC76

    Great review as always…
    I pre-ordered the watch and was eagerly awaiting to received it to try out the Music function, the true unique selling proposition of the device IMO.
    Quite disappointed to say that the watch is guaranteed to work only with 6/7 rather high-end bluetooth headsets out there. Many (including some posters above) have reported audio drop outs when the watch is not perfectly line-of-sight with the headset (which happens every toher step when running right?). I have 2 mpows and Motorola BT headsets and none of them work properly. On the Tomtom support forum they are saying that they are working on a solution but again can only guarantee compatibility with that short list of expensive headsets. If you havent bought it yet and you are not willing to shell out an extra $90-100 on a new headset, I’d wait for if/when the solution will be found.
    In my personal opinion, this is a major technical issues and one that Tomtom should be handling better with loyal customers who have jumped the gun to get this product.

    • Guy C

      I bought a pair of the mpow headphones and have been using them paired to an iPhone 5 to listen to music whilst running. I also use a Garmin Vivoactive to record my run with that also paried via bluetooth to the same phone. I have been very disappointed with the mpow headphones as they consistently drop out – at least 30 times in a 30 mins run! I’m convinced that they cause a BT conflict / interference between the Garmin VA, the IPhone and the MPows as everythin works fine without them. So much so that I’m going to send the MPows back and revert to using wired headphones.

    • DougM

      This is a Spark review, so maybe irrelevant to say how these headsets work with devices other than the Spark. But yeah, maybe they don’t work with anything. The post replied to was an old one, and I originally experienced all the dropouts as well. Would sometimes run with my left arm slightly elevated, or hang the headset receiver away from my head. But, as others might’ve mentioned, TT totally fixed this problem with their latest firmware rev. No dropouts at all now, at least with my TT brand headset.

    • Ryan

      I actually picked up a few pairs of the Mpow Swift for gifts (tough not to for $10 at the time). Ended up making g use of a pair whem my bluebuds walked at the gym. I use the comply foam tips and thr cord clips from thr jaybirds. I wear them reversed, left in right and right in left so they go over the ear and the cord ends up almost hugging thr back of my head like you’d wear the Jaybirds. Never once had them fall out. And the comply’s are comfy and give a great seal. I had extra cord clips from a warranty exchange of thr bluebuds, but you can pick them up from the accessory section of jaybird’s site. They ding you on the shipping so you can always get the comply foams from them as well, or if you know someone else with the Mpow’s, you can split the cost as they send you a couple pair.

      I was surprised to like the Mpow’s to the point I had no desire to replace the bluebuds even when Walmart had them for $68. For $10 plus the comply foams and cord keepers, it’s still a steal. Looking forward to next generation versions as they seem to close the quality gap and show how overpriced the bluebuds and others are.

  71. Aaron

    Hi Ray!

    Thanks a lot for that review, very complete as usual!

    I’d be curious to hear your opinion if you do test it on a treadmill, as I have found it to behave weirdly so far.

    Also, in gym mode, HR seems to be very unstable, I’m not sure why that is.

  72. Diana

    A big disappointment
    What I need is a watch that measures HR and transfers to iphone in EXACTLY same format as polar or cardiosport chest strap. Then I can use my much loved iphone apps in real time
    e.g. ithlete heart rate: shows hr and zone in big display while exercsing – so easy to keep in training zone
    or polar beat: very good but has stoppend working with ios 9, even after following all polar advice on deleting, reloading and pairing and unpairing
    ithlete hrv: whihc measures haert rate variability form my polar h7 chest strap and is wanted by lots of ‘real’ athletes.

    Would also like export of sleep and daily activity (hr every minute – say)

    Finally, as I was contemplating whther to keep it the connection pins distorted so i can no longer connect to MAC or charge, obviously they will replace it but connections do seem more fragile than other watches and do not need the hassle. I note that all app store iphone app reviews are very negative – like mine


    • I’m confused. This is a TomTom Spark Review – it sounds like you had some sort of other product? Also – what connection pins? There are no pinouts on the TomTom Spark (just copper pads)?

    • Diana

      It IS a tomtom spark review.
      To charge the watch you have to attach to a computer via cable supplied. the pins on the cable connector got deformed – see picture.
      Other comments apply to the software on iphone app: tomtommypsorts.
      Watch has great potential, but not there yet imho
      Also do want to know if there are other hr watches that transmit to iphone in real time – but do not know where to ask. Alos asked on your blog onstrapping equipment to byke.

      Your reviews are truly great – recommend to everyone. Thanks

    • Interesting, very odd on connector.

      Yes, the iPhone app is pretty basic. In looking at my notes, TomTom did/does plan to enable BLE broadcasting of the HR signal over standard HR profile (BLE), but not till next year (and no specific time within that).

      As far as other GPS watches, oddly no. Garmin’s FR235 & Vivosmart HR do, but only over ANT+ and not BLE. So those wouldn’t help you. And Polar’s new A360 doesn’t either. Mio’s do, but those aren’t GPS watches unfortunately. The Microsoft Band doesn’t, and neither does the Apple Watch (also not a GPS watch).

      Then you’ve got the Epson units, while their non-GPS bands do rebroadcast, their running GPS watch doesn’t.

      So basically…sigh. 🙁

    • Hi Diana, thanks for your comment. It’s strange to see the pins on the dock distorted as this should not be happening. We’d like to help and see why this happened – can you please send us an email at inbox.reviews@tomtom.com so we can be in touch with you for a solution? Thanks!

  73. Elizabeth

    I am wondering: Can the spark be used right out of the box? Say…umm…Christmas afternoon, when I haven’t been able to update it from my laptop yet, but want to go for a run? Thanks!

  74. Mike

    Hi, I’m a 1 or 2 times a week part time runner (up to 8 miles ave speed) 2 x spinning class sort of person and cant choose between the Spark and the Fitbit Surge. I’ve read both reviews on here plus many more. One of my issues is the size of the unit – I work in an office so wear long sleeve shirt and note the big ‘joystick’ on the Spark and wondered if anyone can advise how this affects them during the working day as compared with the Surge. As only a part time fitness chap am wondering which will be best for me. Any advice appreciated
    Thanks, Mike

    • For workouts, I’d focus on the Spark. Though, I’d agree that the Surge tends to look a bit better as a day to day watch. I didn’t see any issues with dress shirts catching on the Spark pod.

    • I have worn with long sleave cuffed shirt – no problems
      Also considered both
      SPARK is a bit clumsier to change view as it is single button with 4 move directions each going through several menus. so after starting a run and viewing hr, elapsed time calories ther are SEVEN presses to get to clock time. I need to know whether i will have time for shower before next task.
      FITBIT has 3 buttons and swipe to navigate.
      BUT I wold definitely choose SPARK because it can dwon load to pc or MAC. Apparnetly FITBIT only goes tp phone, so view over long period not so useful, although app itself is better.
      Have decided to stick woth chest strap until someone can provide continuous real time transfer to iphone, BLE.

    • Luigi

      I’ve both: the most annoying thing with the FitBit is that you cannot choose the three displayed values (just one, the smaller on the lower part of the display) while with the other one you can easily customize them freely; no options for intervals, training zone, etc. too, but absolutely better app (flawless synchronisation where TomTom MySport on Android is pretty crappy, IMHO: sometimes I’ve to switch off/on the bluetooth, sometimes reset the phone, etc.), far better activity/sleep tracking; I also really enjoy the possibility to pause/start/skip track with the watch. But as a sport watch, the Spark is better. At the moment, I’m not sure in the end which one I’ll keep: actually, they still can be improved and at the moment I don’t feel they’re the definitive choice (=I’ll need to upgrade in the future).

  75. Nandini

    Thanks for the review. I have a 170mm wrist size. Should I get me a small or large size TomTom spark ?

    • Hi Nandini, the small strap fits a wrist size between 121-175 mm and the large one between 143-206 mm. This means both would work for you, depending on your preference, though, since you are towards the higher end of the small strap, getting the large one would leave you with more room to loosen and tighten it.

  76. Bobby Patronaggio

    Thanks for the review, really informative! Just a quick question regarding the cycling mode – do you need to also buy the Cadence and Speed sensor, or will the Spark work fine without it? Will the Spark still give you some details and info if you don’t pair it with a cadence and speed sensor?

    • It’ll work just fine without it (outdoors), you just won’t get cadence. And indoors, you won’t get speed.

    • Elizabeth

      I see that there is a bluetooth Polar cadence sensor on amazon for much cheaper than the TomTom one. I would think that they’re compatible, seeing as it’s all BT. It’s on my Christmas list! 🙂

  77. Steve

    For those looking for another alternative to have music in a fitness watch or are die hard MotoActv fan, the details on Moto360Sport are starting to come out with availability in January. Hope it’s close to MotoActv feature list. link to motorola.com

  78. Bobby P

    Thanks for your reply! I have one more question which I hope isn’t too silly. The gym I go to actually uses the Mio Link heart rate bands and so I was thinking that I could just pair this with the spark instead of spending the extra money on the HR model. However, if I did this, would I also be able to pair Bluetooth headphones or a speed/cadence sensor as well? Basically I’m wondering if you can laid multiple Bluetooth devices at the same time to the spark. Thanks!

  79. Mario

    Hi Ray

    Is it confirmed that they’ll get phone notifications soon?

    I need as xmas gift for my brother and cannot decide between garmin vivoactive and tomtom spark cardio. Cost is more or less the same. I really like that he would be able to run just dressing the watch (w/o the HR strap). Any suggestion? Does it have a good firmware as garmin? I see several posts complaining about bugs.


  80. Just to get some clarification… does the Spark on play music in a shuffle mode?

  81. What I meant was “ONLY” play in a shuffle mode…

    • Stephen Casey

      No – you can upload playlists to define what order it’ll play in (and choose between them).

      By default, it’ll just play in shuffle though.

  82. Joeri Nysen


    I have a couple of questions if you have any time to answer them.

    Would you choose this over the Garmin Forerunner 225 taking everything into account and why (not)? To me it doesn’t matter if I can listen any music via my watch, I just want the most accurate measurements and best value for the money. My workouts mostly consist of running, working out in the gym and occasional swimming (although I’ve never worn any sportswatch whilst swimming).

    Have they already done any of the updates they’ve been promising and how have these turned out? I’ve read that they no longer use the red LED’s because it doesn’t add to the measurement, which seems odd because why would you’ve chosen to install them in the first place then?

    Kind regards,


    • I would generally say the FR225 is more accurate than the TomTom Spark (but note the FR225 is not the same as the FR235).

      My guess is that the use of red LED’s has nothing to do with not adding to measurement, but with causing battery drainage challenges.

    • Joeri Nysen

      Have you had any chance to try the function where you can race against a previous time? Might be something that interests me as I’m trying to get my pace up on the 10K runs and that might be an extra motivator.

      Thank you for the awesome reviews!

  83. Robert McNabb

    Great review. I am a bit of a luddite, so please bear with me. I actually want a watch such as this to measure my fitness during pick up soccer games. Two questions: 1) Do you think this watch would be good for that task? and 2)Do I need to have a smart phone to operate? In other words, can i just show up at the field with my watch, adjust settings and track my distance travelled, HR etc.



    • Fast stops/starts can be tricky for an optical sensor (of most types), so it’s hard to know as I haven’t tested in that scenario.

      You do not need to use the phone at the field (or anywhere else).

  84. Asaf

    Hi fellow Spark users
    Can someone please explain why I don’t see any playlist on the TomTom MySport Connect? Using Windows 10, tried to export playlist from itunes to music folder. XML, M3U… With no success.
    Help appreciated!

  85. Dave

    I bought this exact watch (with the music feature) for my wife along with jaybird headphones and it has some problems. Pairing the the headphones along with the phone is not easy and it appears that it is not very consistent. She spent at least a couple hours trying to get both devices paired, and then one would drop off and she would have to start all over. Also, the watch does not calibrate well for the treadmill. Way Off!!! Upon reading about the issue… it doesn’t seem like there is an actual callibration, rather a correction. Unlike my 310xt, you can’t manually set a callibration factor. I understand that the watch uses arm motion to judge distance, but it just doesn’t work. It is recommended to do this 5 times to get it callibrated, but it just doesn’t callibrate. It gives the same half distance after the 5 times needed for “callibration”. I understand that it is tough to get it 100% accurate but the watch is consistently half the distance off.

    • Phil

      I’ve been experiencing the same issues with the treadmill calibration. No matter how many times I set it, the watch continues to report distance half of the actual value run. This leads me to believe it’s just a distance adjustment for the current run, not a calibration for future runs. The forums on tomtom’s site seem to indicate it’s a common/known issue.

      Considering most of my winter running is indoors, I may have to return this if it doesn’t get fixed quickly. I shouldn’t have to count laps on the indoor track or remember to update the distance afterwards. That’s what I got an indoor-capable watch for.

    • GMRO

      ANNDDDD this is exactly why I have not pulled the trigger as of yet. And why I asked Ray about the treadmill feedback above.

      IF device manufacturers are going to 1/2 arse products that cant track accurately HR via optics and have solid GPS and indoor track/treadmill – I’m out.

      Shame they waste our money on things that fail per what they are “promised” to do. Not as if these things are cheap far as pricing…

      What a shame.

      So for now I’m still in a holding pattern.

      Thanks for the feedback on the device short comings!

    • Phil

      After seeing all the comments about the treadmill distance being half of actual, is it possible that the calibration is working, but someone forgot to multiply distance by 2 (for two arms/legs but only one watch)?

      Not sure which case is worse, but whatever the error is, it needs to be fixed quickly.

    • JGav

      Yes, I too just got this watch and do 80% off my running on the treadmill. I was hoping to see a treadmill review here but have not :/ So far, it is not accurate at all and upsetting that is has not been fixed. I will give this 1 more week but then will be returning it.

  86. Mike

    Just done my first run with new tomtom runner 2. Very impressed! However couple questions. Calories – I did steady 4.5 Mile 45 minute run but says I burnt 709 calories! I thought the average burn was 100 calories per mile? Heart rate- ave 149! think this is far too high??( I only pushed hard 2 or 3 times)
    Any thoughts?

    • TomTom Community Manager

      Hi Mike,
      The calorie count is directly related to the heart rate. If the heart rate is off, the calorie count might be incorrect as well. This link will give you more instructions on how to improve the heart rate readings link to bit.ly.

    • Richard

      Thanks for the excellent review, Ray.

      I just got a TomTom Spark and have completed two runs. I have the basic unit, with no heart rate sensor and no music. So far, it’s great. It met my expectations. One minor issue is that the mileage and time measurements show up differently on the watch and on the TomTom MySports website. At the end of my runs, the watch showed:
      8.04 mi in 1:12:06
      2.04 mi in 17:10

      Once I connected it to my PC and the info uploaded to the TomTom MySports website, the info was:
      8.09 mi in 1:12:05 (0.62% longer distance)
      2.05 mi in 17:09 (0.49% longer distance)

      Anybody know why this happens?

    • Jennifer

      I thought running was done through MET, not HR? At least that is what was said by TomTom earlier in this thread of discussions…

  87. DO NOT lose the charging cord or you will end up with $249.00 worth of plastic junk. The charging cord and accessories are not available in the USA and after NUMEROUS phone calls to customer service, which is down right horrible and sounds like it’s based in India, there has been no resolution and no cord provided. Just a “I’M SORRY”

  88. Can I connect (pair) the TomTom spark cardio + music with a Bluetooth HR chest monitor? I already know it does have a built in HR but just thinking about trying to get more accuracy.

    Regards and thanks in advance for zyour answer-

  89. Angel

    Just got spark for Christmas. spark synced to my phone great the first time now it won’t do it again. The watch picks ap the phone and gives me the code but my sports app says it can’t find it. The watch is listed and there is an x on it or it will let me tap it circle spins but then says it can’t find it. Earbuds work great. I’m assuming it’s the app. Uninstalled and reinstalled the app no luck. Any ideas?

    • Asaf

      Angel, you can always do a full factory reset. Also, try deleting the BT from the list and then pairing it again (via settings on your mobile). Finally, make sure no other app is simultaneously running when trying to sync (just in case…) and that the TT app is open in the background.

    • TomTom Community Manager

      Hi Angel, please contact our Customer Service via link to bit.ly; they should be able to help you out.

  90. Nuno

    I Bought this watch (Spark + Cardio + Music) in November and tested for about two weeks, before I returned to the store, it was an enormous disappointment.
    The main problem for me was the GPS, it was very slow and sometimes I couldn’t acquire GPS signal, this was very strange, since I didn’t have any problem acquiring GPS signal using the the tomtom Multi Sport cardio, in both locations I used to train, the multisport cardio was very fast getting the signal.
    Honestly I Expected more, for me it’s probably the end with tomtom, the app is still very week, had to use the mapmyfitness.com, the updates to the previous watch multi-sport cardio didn’t added new features, and probably the same will happen to this watch.

    • It would have been interesting to know whether or not you received the GPS QuickAssist information download (can check via settings, but now that it’s been returned – hard to know) – since GPS signal acquisition should be in the seconds.

    • Nuno

      I Ray, first thank you for your reply, I had received the GPS QuickAssist Information, the first time I tried the watch, I believed this was the problem so I connected the watch to the computer an check the quickgps I got the information it was up-to-date
      But the problem persist, I execute a factory reset of the watch and updated again but the gps was still slow, and again the quickgps was up-to-date, it was strange since as I said before, I am using the multisport cardio in both locations i use to train and didn’t have any problem.

  91. Mike

    I have updated my account (couldn’t change any settings on phone app) on web from 24 hour time to 12 hr time. It will not change on watch. It shows up correctly in app now, have seen it update gps fix 3 times, but my phone and watch doesn’t look like it is syncing good. It wouldn’t updat steps yesterday, I had to repair this morning. It has steps now. Have not done an activity yet. Will do one today. App syncing needs improvement.

  92. Nicole

    Hi Ray,

    Thanks for your insightful reviews!

    After doing much research, including on your site, I had narrowed my wishlist down to the Tomtom spark gps cardio + music and the garmin 235. I received the Tomtom for Christmas and have been using it for a few days, so I thought I’d share my thoughts here. ..

    1) I have a Samsung Galaxy s5 and I’ve had a lot of issues syncing between the mobile app and the watch. All apps and software are up to date. It’s very frustrating.

    2) I was under the impression that the Tomtom tracked sleep, but I cannot find these data anywhere on the website or the mobile app, so apparently this is false (or it may exist, but I just can’t figure this out)? The manual on the Tomtom site says to go to the “Progress” tab in the mobile app, but that tab doesn’t exist in the android app right now?

    3) I was also disappointed to find that you can’t really check your heart rate at any given time; you can only see your heart rate during an activity.

    4) I’m still really hoping for continuous heart rate

    In summary, I’ve found that it works well as far as tracking runs (heart rate and gps), but sleep tracking seems basically nonexistent. Also, even if it doesn’t record heart rate continuously, I’d like to be able to check it manually, without starting an activity.

    I’m really disappointed that, according to a Tomtom reply above, calories burned aren’t calculated using heart rate?!?! That was one of the main reasons I narrowed my choices to the Tomtom and the garmin 235…I really hope I read that wrong and this isn’t the case…

    I will give the Tomtom a few more days, but I’m on the fence about keeping it. I may return it and spend the extra money on the garmin 235.

    I hope other readers find this helpful.

    Does anyone know anything about the sleep tracking issue? Or whether the calories burned calculations use heart rate at all?

    • Regarding sleep, I only have the iOS app, but you can see it within the screenshots in the review (both on the device, and on the app). Perhaps you can find those same pages on your Android app.

      (To find, just search on this page for the word ‘Sleep’, it’s the second instance you’ll see.)

  93. Larry

    Thanks for this and all the other great reviews! You mentioned that, “The TomTom Spark is one of the few GPS watches out there that has storage for music.” What other choices are there?

    • Adidas Smartrun GPS. Also there are a few smartwatches, such as I believe one of the Sony units.

    • Ryan

      The Sony SW3 is one. Samsung Gear S2 is another. The S2 can also take a SIM and be your phone, but it runs Tizen and not Androidwear so your options for running apps is limited to Nike I believe. Many were getting excited about the LG Urbane 2, but LG pulled it. It seemed to be as close to a Motoactive replacement as one would get.

      I’m guessing you can’t transfer music from your phone to the Spark. So that’s a dealbreaker for me. I’m also a jilted multisport owner. Over promised and under delivered on the updates and improvements. Not to mention simple things that should be on/off type settings are modes forcing you to choose a mode to get something you want while sacrificing something else. Never understood it. I downgraded to the Runner for $50 after having too many problems with the MS. I sold my warranty replacement I was shipped and pocketed the change. Then the button on the Runner snapped off which made a morning alarm pure hell. I think I’m going old school with the new garmin 230 to get my 4 metrics on the screen and my Sandisk Clip and wired buds. Still relegated to transferring via the computer for music. Or I can just pop the card from my Note 4 in the Clip before a run.

  94. James

    Has anyone else had problems with activities not exporting to TomTom MySports Connect? I have had the watch for a month and three runs have not uploaded when I connect to my PC by the USB cable. They show up on my watch, I can see all the details of the run there; but the day of the run is not in the folder file and did not export. There is an answer in the Troubleshooting section online about how to Re-export old activities, but I get stuck on Step 5 when it says to go to the activity folder and select the date of your activity, because mine is not there. Again, I can see the runs on my watch. If this keeps happening and can’t be fixed, I am going to return it.
    Also, after I disconnect from my PC, the 12 hour clock goes back to the 24 hour clock, anyone know how to lock in the 12 hour clock?

    • Mike

      Mine will not change from 24hour clock either, WTH?

    • Lil

      You should be able to go into setting screen (press down from main screen), clock and 24hr and change from on to off and that hopefully should fix the problem.

    • Mike

      How I did not see that! Thanks!!!

    • James

      The problem is that it will not stay on the 12 hour clock after I disconnect from my PC, it goes back to the 24 hour clock and I have to change it back to the 12 hour every time.

    • Lil

      James do you have your computer set to a 24hour clock? there is an option when you plug your watch in to download your runs, – ‘set time and date to match computer’. Maybe change that to no, and it may stop it from happening.

    • Mike

      Could be the time settings under account on the website as well. On Mon I had it set to 12 on the account, but it wouldn’t change it for me. It may actually update his and its set to 24 there.

    • James

      Thanks Mike! It was the setting on my account on the web site that makes the watch stay on the 12 hour mode after disconnecting from my PC.
      Now, if only I can get a solution to my other problem (see original post) about activities showing up on my watch but not uploading to My Sports Connect. A further development, two days ago, my three missing activities suddenly showed up on My Sports Connect, some up to two weeks late. And today’s run did not upload, who knows when or if it will show up….

    • TomTom Community Manager

      Hi James, the missing activities folder is odd. Please reach out to us via inbox.reviews@tomtom.com with a brief explanation of the problem or just a link to your comment here so that we can give assistance.

  95. Nicole

    Hi Ray,

    I did notice the screen shots in your review, which is why I thought it was operator error…and it could still be, but I’ve uninstalled and reinstalled and restarted and updated, etc., and I still do not see any “Progress” tab in the android app…

    I do see the hours of sleep on my device, by the way, I just don’t see any sleep data anywhere else.

    Maybe it has something to do with the marshmallow update? Does any other readers have the Tomtom app and an android phone? Too bad I can’t get any feedback from Tomtom itself…

  96. Cybermambo

    I am training for my first sprint triathlon. Besides individual training sessions, is the TomTom Spark Cardio suitable for use at a triathlon race (sprint, OD, HIM, IM)? would it be able to work well enough for swim, bike and run legs compared to the Garmin 920XT and Fenix3? (understand there is a big difference in pricing but TomTom may be distrupting this range of products) . Thank you.

  97. LIL

    Thanks for the great review as usual. I had an tomtom multisports and have now purchased the tomtom spark cardio. But I am just wondering if you have tested the Training zone pace setting. I used this on my old mulitsports and once I set the pace training zones and start my run it would go to a graph screen and show a if i was in my target zone or not. But the spark cardio goes to the graph screen but does not show any vertical graph lines while running (see picture). Tomtom now tell me that this feature has been removed because of feedback from customers, however the screen is still there and just stays blank during my run. This is a feature I used all the time with my multisports and I am very disappointed that tomtom have removed it. However I can still get a graph screen working in the Heart zone setting. Have you had any issues with this setting?

  98. joanne

    I’m really confused about the daily calorie count that it displays in the same menu as steps. Yesterday i put my watch on later in the day and after 1 hour of pottering around my h ouse it said 2200 calories. Anyobe know what this means as it clearly is not calories burned. If it is, its wildly inaccurate (i wish)

    • TomTom Community Manager

      Hello Joanne, calories also include the base metabolic rate, which are the calories burned by the body without being active, although 2200 kcal does seem a bit high. Should you ever have inaccurate readings again, please reach out to our Customer Care team so they can evaluate whether your watch is functioning as its supposed to. You can contact the Customer Care team via link to bit.ly.

  99. Matthew

    I appreciate all the reviews you do here. So far, despite a few quirks, this watch is holding up well for me. The one problem I am starting to see is more a problem with long-term use. I am noticing skin breakdown where the hrm contacts. There’s a jagged edge that makes up the unit that I think might be causing it. Normally, I wouldn’t care and just stop wearing it outside of working out. But this is supposed to be used for the long-term. Step counting and monitoring sleep. Wondering if anyone else here is seeing something similar?

    • TomTom Community Manager

      Hi Matthew, I am sorry to hear that. You should be able to use the watch for longterm use, of course. Please reach out to our Customer Care Department via link to bit.ly and explain your situation to them. Thanks!

  100. Angel

    Is it possible to pair up headphones in the middle of a run or do I always have to pair them before I start?

    • TomTom Community Manager

      Hi Angel, to pair your watch with your headphones you have to see the start screen which you only can when you’re not in the middle of an activity. So, no, it is not possible to pair your headphones with the watch during a run.

  101. Peace

    Just got a new tomtom spark cardio music, and after i start using it, i just realised that my unit got no click sounds, it can only buzz (although i already have the the setting as click+buzz)
    Has anyone run into this problem before?
    Thanks a lot in advance.

  102. Mrs Pandi Stepan

    I read your review which seemed accurate and evenly balanced and i bought the TomTom Spark with music – it has just arrived. i cannot properly charge it as i am unclear how to attach the cable to the watch – i took the strap off and managed to get the end of the cable into the charger but it was impossible to remove without using a tiny screwdriver end to loosen it enough to take the cable out – what am i doing wrong??? Help, please, or it is a very expensive mistake!

  103. Kenneth

    Hello Ray (or someone else),

    You have the different training options like goals, intervals, zones, etc.
    Suppose I want to run for 30 minutes in a certain zone, can I choose the training option ‘time’ (set on 30 mins) AND ‘zone’ (set to certain zone) at the same time?

    Another question: for which reasons would you prefer the Forerunner 235 to the Spark?

    Thanks for the great review!

    • TomTom Community Manager

      Hello Kenneth, you can set a goal for one of the 4 metrics on the watch – a combination is not possible at this point.

    • Kenneth

      Hello TomTom-manager 🙂
      Thanks for the answer. I bought the runner 2 + cardio + music this week. Did my first run yesterday and happy with the product!!
      Although it would be nice if a combination of goals is possible in the future.


  104. KTS


    Can anyone tell me if the clock face can be changed. I plan to use everyday but don’t like the way the time is displayed in these pictures…

    struggling to decide on between this and the Polar M400…

  105. Hey, first off, thanks for such a fantastic review as ever! You are always my go-to place when I’m looking for a new sports watch 🙂 Just a couple of questions on switching between running/cycling modes, if that’s OK:

    1) Is it easy to switch between the two? On my Garmin it’s one press of a button – I don’t mind if I have to do a couple of clicks to switch between cycling and running, but obviously it’s inconvenient if I have to dig deep into a menu path every time I want to switch between activities.

    2) Does it store separate metrics setups for each activity? e.g. if I want average pace, current pace and time for running, but distance, speed and time for cycling, will it automatically change the fields displayed on-screen when I change sport mode from running to cycling or vice-versa, or do I need to re-configure the metrics screen every time?


    • Or, alternatively, is it possible to configure different metrics screens I guess, so that I can just switch from my “running” screen to my “cycling” screen as required?

    • Got an answer from TomTom’s twitter feed – for anyone else wondering the same thing, it does indeed store different metrics for different activities, so watch has now been ordered 🙂

  106. Tina OConnor

    Has anyone managed to break the screen on the Tom Tom Spark? My 14 year old got one for Christmas and it lasted all of 8 days. She has no idea how she cracked the screen, but unfortunately it happened in a pool and I am pretty sure that no amount of drying out in rice will help the electronics recover!
    I am a long time Garmin fan so know how they would deal with this. I am waiting for Tom Tom to respond as they are having phone issues today…….

    • Matthew

      My experience with the multisport is the glass is pretty fragile. As I was removing my multisport from wrist band, it dropped all of 2 feet to the ground and cracked from the corner. If it has been only a couple days, call tomtom support because I believe it is still under warranty. Mine was about 3 months old and well outside the window.

    • Tina OConnor

      They responded immediately and will replace the watch.
      So far I am impressed.

  107. Mike

    Hi couple of questions-
    -Does anyone know if the calories burned during say a run also include the day 80 calories burnt naturally when inactive?
    -I did 2 exact same runs, why did the slowest run which took 45 minutes not 40 minutes show me as burning 100 calories more?! The quick run I did interval training so lots of HR spikes – was sure this should have burned more calories?

    • TomTom Community Manager

      Hi Mike, calories are calculated with MET tables which are based on pace and distance. The HR isn’t taken into account which explains why your faster run burnt less calories according to your watch.

    • SS76

      Why wouldn’t the HR not be taken into account when determining calories burnt? That would make it more accurate, so why not?

  108. Allan

    Hi there.

    Got the tomtom for my wife and a garmin 235 myself.
    The pedometer (step counter) seems way off on the tomtom. A work day at home easily counts 10000+ steps. During dinner it counted ~200 steps where garmin counted 0!
    compared to a old school pedometer during a 2km. walk it seemed ok but seems as if small movements are counted also.
    Any experience with this?

    • Matthew Evans

      I had a similar issue when I first got mine. We drove 8 hours from MI to NY and it was calculating somewhere around 4000 steps during the ride. I read you should do a factory reset through the computer to fix it. I haven’t noticed too big of discrepancies, but what I would suggest is to have the same person use both watches for a day to see where you end up after the reset. Planning on having my wife do that this weekend with her fitbit.

    • TomTom Community Manager

      Hi Allen, the watch uses the data from the accelerometer in the watch to calculate steps. Lots of arm movement may result in extra steps; however, you numbers seem very high. I would suggest to get in touch with our Customer Care Department via link to bit.ly.

    • Allan

      Hi I’m glad to hear from you.
      Being a sw. engineer my self I have no problem in seeing the challenge for the watch. It has to determine what is a footstep and what is not. But to be honest if the algorithm used for this, detects eating dinner as 200 steps or driving to work as 4000 it simple isn’t good enough to be sold!
      Then the feature should be removed until the algorithm has been properly maturd and tested.
      I have found out that the issue have been raised at tomtom site a month ago but there is no response about a solution:
      link to en.discussions.tomtom.com

      Garmin faces such issues and releases new firmware often. Even removes features if not found good enough.
      When can tomtom users expect a fix of this relative simple problem which I must ad is a KEY feature of the product? (Only measured value available with one button click)

      Best regards.

  109. Gerhard Olsson

    From the review:
    Note: I’ll put all of these files up in a ZIP file in the coming days for you to download, just compiling them all and wanted to get the review up for you in the meantime.

    Are the tracks posted?

    I am disappointed in my Garmin 920XT GPS and consider a Spark instead. The 920XT is always off the track (compared to a 305 and other), distance calculation is still OK unless you run trails, that are consistently cut in corners (I have tested 35 laps on a 5km trail).

    Any comment about the Spark accuracy compared to other units?

    The first gen had a SirfStar V chipset, is the same used in the Spark?
    (a good start for a good GPS, not all)

  110. Matthew

    This may be more associated with my link than my spark; as I am just now realizing the same things persisted for my multisport. When I ride, I tend to use my Mio Link to handle the hrm function so I can throw the spark on the handlebars. I just realized there are distinct gaps in the heart rate. Not just drop-offs where it mis-reads, but actual breaks in the lines. I think I’ve noticed it on every ride I did this combination. Anyone else try a mio link in this fashion? Are there better interactions with a different hrm dedicated arm band?

    • Matthew

      Some of these gaps range between 20 and 30 seconds as well…so fairly substantial.

    • Gerhard Olsson

      Seem to be some that have problem with Polar H7 too
      link to en.discussions.tomtom.com

      So the Spark seem to be like the first gen: Limited by SW and specific issues

    • Matthew

      I wouldn’t blame it on the spark specifically because as I looked back through my time using the multisport cardio, the same discrepancies existed. Now the link has been criticized in the past for dropping connection with phones. Was thinking that may be the same issue. Both the spark and multisport by themselves worked fine. I’m thinking its more of the ANT hardware that connects to the devices.

    • Gerhard Olsson

      Not ANT but BlueTooth Low Energy for TomTom (and Ambit3 and Polar V800 and phones). The Polar H7 band users had no problems i other setups, I have not heard much from other watches/phones. So I would assume this is the TomTom watch that is the problem

  111. Yes, I found this article VERY helpful. I have been trying to figure out which gps unit I want for running with all the features I want and this article answered all my questions and helped me make my decision. Thank you very much!

    As always, top notch review.
    I noticed in your review and on other review websites (eg engadget) that the smartphone integration (sounds like just notifications?) is planned for Dec 2015.
    I checked the TomTom website but it is scant on detail – are you aware if this has been implemented yet (and what they decided to include – eg missed calls and perhaps ability to read SMS?).
    This watch sounds really promising and quite a bit cheaper than the FR235 – I think this would get me over the line.

    • I haven’t heard of any specific updated dates. I’ll poke in though this week, or perhaps the TomTom Community Rep here will chime in.

    • Matthew

      While the potential is there, I wouldn’t sell myself on this unit unless it is for what it is now. As others have noted here, tomtom tends to make broad claims about potential, but once the device starts selling, they have often failed to deliver.

    • TomTom Community Manager

      Hi Dean, features like message and email notifications, 24/7 heart monitoring, as well as the option to share activities on Facebook and Twitter are in development and will be announced in 2016.

    • Dean E

      Dear Tom Tom,
      Being announced in 2016 is a bit too broad a timeframe for me. Can you be any more specific?
      I don’t care about Facebook or Twitter posting – besides, no doubt you can do that from the app, I don’t need to do it from my watch. Why further complicate and use up precious memory.
      I do care about call/message notifications. 24/7 HR monitoring sounds great.

  113. Chris B

    Torn between the Garmin 235 and the TomTom Runner 2/Spark with cardio. Custom workout programming seems to be a differential – how flexible is the Tom Tom? I note Garmin can be pre programmed from a laptop etc.

    Grateful, and great reviews

    • KTS

      Garmin 235 is a league ahead by the looks of it.. I was torn between the spark and the garmin 225.. same price bracket .. I went with the garmin.. only really because I didn’t like the clock face of the spark for wearing all the time, and it can’t be changed I was told… but happy so far with my purchase…

    • TomTom Community Manager

      Hi Chris, with the Runner 2 and Spark you can choose between different types of activities like Run, Cycle, Swim, Gym, Treadmill, Indoor Cycling, Freestyle, and Stopwatch. For each type of activity you can then choose a training program like Goals, Intervals, Laps, Zones, and Race. If you select Goals for example, you can set a distance, time, or calorie goal, whereas selecting Zones e.g. gives you the option to train within a target zone for pace, speed, heart or cadence. There are lots activities and training programs to choose from which makes the watch a very flexible tool. I hope this helps. If you want to read more about the above, please have a look at pages 29 and following of the user manual. You can find the user manual here: link to bit.ly.

  114. Eric Spenlinhauer

    Thank you for all your in depth reviews I use them as my before any purchase. I have purchased the Garmin vivosmart HR and Band 2 and have returned them both and just bought the TomTom Cardio Spark. My first question is that I can not seem to find out if it monitors my heart rate 24/7 or just when I start an activity, my gut tells me it only when I start an activity, but I hope not this is by far the most comfortable wrist heart rate monitor I have worn to date but looking for something that gives me 24 hour heart rate monitoring. I have looked at the fitbit surge but it just looks too big and uncomfortable. Do you have a suggestion for a wearable 24/7 heart rate monitoring device that I have not bought?

    • TomTom Community Manager

      Hi Eric, 24/7 heart rate monitoring is currently in development and will be introduced this year.

    • Gerhard Olsson

      Nice to see TomTom here – not so often on the TomTom forum.

      I have considered replacing my Garmin 920xt with a Spark but the SW is very limited (I have bought and cancelled the gen 1 due to this). Very limited intervall, no always on lap mode, no last km or current lap pace field, no cadence, only 3 fields. You almost have a winner.

    • Ryan

      Yes. I never understood while simple on/off settings on other watches are mode only on the TomTom. They force you to choose specific things that should be general options. Big complaint for a long time in the forums and never addressed.

  115. SS76

    Ray, any word if the TomTom team is any closer to relaunching the app? In your review you mentioned that TOMTom has devoted an entire team to this, just wondering if they’ve actually released anything?

  116. Mike

    I paired my headphones once and they worked fine. Now I cannot get them to show up on the watch. I have tried to pair again, and it cannot find them. Any suggestions?

  117. Israel

    So I have a Suunto Ambit 2s. I am looking only for an activity tracker. Right now Imy options are the TomTom spark and the Vivosmart hr. Any suggestions?

    • Gerhard Olsson

      There are many in the TomTom forum that are not happy with the Spark as an activity tracker.
      * Step counter reacts on many other than steps
      * One clockface only, not time and steps at the same time
      * (not yet) continous HR

      The Spark seem to have merits, activity tracker is not a strong one though

  118. Mike

    Anyone else have problems with pace? When I set my Runner2 for mile laps (and when I don’t) the current pace is anywhere from 20-40 sec fast. The mile laps will report correct. Sometimes pace starts off okay for the first few minutes but it quickly losses the plot. I sent an email to TomTom and their only response was that they know there is a problem. A little underwhelmed to be told only that they know about it and nothing else; timeline for fix, sorry, etc etc.

    • mike

      the response I received from Tom Tom…..

      “Thank you for taking the time to contact TomTom Customer Support. My name is Jitendar and I will be glad to assist you.
      as I understand from email you are getting inaccurate PACE information of your TomTom Sport watch. I’m glad that you emailed us and I will try my best to answer the query.

      We have indicated that the issue you are experiencing with the PACE inaccuracy of your watch is a situation we know about and which is under investigation.

      I will also ensure that our relevant team is aware of this and take this as a priority. Please be rest assured that we will take all measures to have it fix as soon as possible.”
      Is it possible to get a firmer timeline?
      community manager?

    • TomTom Community Manager

      Hi, the latest release (1.2.0) has small pace accuracy improvements; more to come in future releases as we are continuously working on it. You can always check the latest software updates here: link to bit.ly.

    • Juanjo Ramos

      Just checked those release notes for the 1.2.0 update. Can somebody please confirm that the Tomtom Spark Cardio now supports continuous HR monitoring?

  119. Steve

    Am I able to connect a heart rate strap and headphones via bluetooth at the same time?

    • Michelle Squitieri

      Can you use an HR chest strap or scosche hr strap with tom tom spark in the pool to gather and see hr?

      Thanks, your reviews are great. But I would like to know the answer to this question for other fitness watches too.

    • No, as it won’t transmit through water. Which is the same problem for most watches.

      Some companies have workarounds that sync after the fact, like Garmin with some of their watches being compatible with the HRM-SWIM and HRM-TRI straps. And Suunto with their Movesense straps. And finally, Polar can transmit through water on analog frequencies for certain units as well.

  120. Miranda

    I recently purchased the TomTom Cardio Spark Multi and am having a hard time getting the battery to last past 2.5-3 hours. I bought it for tracking my current pace, my training and getting through a marathon. But at that battery rate I will not. I was running music and GPS of course which is why I bought it. I don’t get a good current pace either. Do you have any suggestions for me. I am probably going to return the unit and get something that last a little longer. I also have very small wrist which makes find a comfortable watch a pain. Any suggestions??

    • TomTom Community Manager

      Hi Miranda, when the battery is fully charged, you should be able to use your watch for up to 10 hours of activities that need GPS reception (e.g. running and cycling). The watch loses charge more quickly if you connect it to sensors like a heart rate monitor or cadence sensor. A lot of beeping and buzzing also drains the battery faster as well as using the back light. If you feel like your watch is loosing battery quicker than it should, please get in touch with our customer care team via link to bit.ly

  121. TZoe

    Hi, thanks for the review!

    Do somebody know, what’s the size of the memory for activities (activity-tracker and workouts)? It’s not the storage used for the music as far as I know, because when you browse the flash-storage there are no files for activities. So there has to be another storage…


  122. Bill

    I was getting increasingly excited about choosing this watch…. until I read…”The metrics that are shown are: Clock, Duration, Distance, Pace, Avg. Pace, Speed, Avg. Speed, Calories, Heart, HR Zone.”

    Thanks for the tremendous review… but I really would have thought that you’d highlight this as a showstopper for a lot of runners. Who doesn’t often use lap pace, and lap distance? And much more. All that technology, and they have chosen not to give flexibility /customisability in the way the data is displayed.

    There is much about the TomTom that I like, but with a slightly heavy heart, I’m going to have to head back to Garmin.

    • TomTom Community Manager

      Hi Bill, you can customize the screen to fit your needs and choose one main metric and two secondary ones. The main metric is shown in a larger figure in the main part of the screen. The secondary metrics are shown at the bottom of the screen. Page 31 of the user manual explains how to change the metrics. You can find the user manual here: link to bit.ly

    • jake

      without lap pace i have to purchase a different watch. it’s a complete show stopper. that’s the feedback mechanism to show whether you need to speed up or slow down to achieve your time goals for the mile, or whatever lap distance you choose. or whether a goal time is achievable after getting gassed running up a hill.

  123. Adam

    Looks like the Spark Cardio versions just got an update to 1.2.0 which includes 24/7 heart rate monitoring.

    link to en.discussions.tomtom.com

    • Joost

      Yes and the update fixes some bugs plus better BT headsetsupport – nice update TT.

    • Does this mean that the heart rate reading is viewable on iphone in real time,as with chest monitors?

    • Ruud

      It does spot checks every ten minutes and uploads it to TomTom Mysports. I’ve attached a screenshot from my Mysports app. (Sorry, it’s in Dutch but you get the idea…) Real time heartrate is only when you start a workout.

    • Thanks Ruud

      It is DURING WORKOUT I need to see on iphone, so I have visual of whether in band.
      Polar chest monitor does tis with either Polar Beat [free] or ithlete HR [£6.75 but very reliable]
      Does current version of spark cardio do this?
      Grateful for any comments, including from TomTom monitoring person, in addition to DC’s great review

    • Ruud

      Hi Diana,

      watching real time HR info via the iPhone Health app or in any other way on your iPhone is not possible. I believe the TomTom Community Manager already addressed this point somewhere in this thread.

    • Diana, why do you need to see it on your iPhone specifically, though?

      The TomTom Spark Cardio can tell you:
      • your heart rate; and
      • the corresponding heart rate zone, according to the individual settings in your MySports account.
      You can set both of them as secondary metrics displayed numerically (on the bottom corners of the watch’s screen) if you want, and/or you can make one of them the primary metric displayed numerically. You can even see a real-time chart of your heart rate on the screen of the watch, as an alternate display to numeric data.

      If you are wearing the watch so that you can use its optical HRM during your workouts, you can definitely get a “visual of whether in band” if needed. You just cannot rely on your iPhone for that, if that’s your personal preference. No apps. No colours or fancy displays, no customisation in the mode of presentation. No integration or uploading of data during workouts.

    • Clearly software is much improved since I tried one few months ago.
      Presumably it can also upload record of HR during training interval?
      I want it for indoor rowing and the angle on the wrist means I cannot see display without turning my head whihc distrube rowing rhythm. iphone is strapped i fron of me and I can see at all times

    • Ah, rowing. Fair enough, I hadn’t thought of that at all, sorry.

      By “upload record of HR during training interval”, I take it you mean uploading only after the workout session is complete, and not while it is in progress? If so, then yes, it can.

      You ventured, in another comment below, that “ONLY advantage of watch, any watch, is HR without chest strap”. For me, the advantage of using a sports watch – with optical HRM or without – is to track and monitor the metrics without looking at or carrying any phone while I run or swim. (In particular, I have no intention of ever getting an iPhone. It irks me that most sports watches don’t support integration with Windows Phone handsets, and I have to resort to using an Android device as a second-best option.)

      Ray’s reviews have certainly convinced me that an ECG-based HRM is still a necessity in one’s toolkit (for measuring HRV, estimating VO2Max, etc.) However, people like me who are simply trying to get fitter in a disciplined way, the optical HRM is good enough for day-to-day HR zone based workouts.

  124. Jana Mottlova


    thank you for the great review. I just have one question regarding the HR. When I set up the HR min. and max. (i.e. 120 – 145), it reports to my headphones (and also vibrates) that my HR is ok or it is too high or too low. But this reporting seems to be very random. Sometimes I get the feedback to my headphones but sometimes I dont at all and I am not pretty sure what I am doing wrong or how this works. Could anyone advice on this? Thank you! Jana

  125. DougM

    This was the best review out there, and instrumental in my decision to buy a Spark. The feature set was what won me over mainly. I just don’t know anything else out there that provides GPS, heart rate and wireless music. The real question for me was how well these features would work, or if they’d work at all. I had just returned a Fitbit Surge because its optical heart rate monitor didn’t seem to work at all for me. It’s GPS got wildly flaky as well at times. This review shows TomTom (TT) data that indicates very acceptable accuracy for all functions. Briefly, here’s my take, today. GPS is great. It may meander a few meters off the trail here and there, but the maps, distance, speed, and elevation gain calculations meet my needs. Don’t really understand the “quickGPS” that needs updating, but whatever. Finds GPS lock relatively quickly. The music quality on the TT headset is better than expected. Really great, actually. It started out with a bad dropout problem, but that was fixed completely with a recent firmware update. So of the big three features (to me), GPS and music are winners.

    But then there is heart rate. If I could get the data shown in this review, it would be a dream come true. Not so, for me. I can say that the optical HRM works better than the Fitbit one. And I can say that very often, it is reading very accurately. But the OHRM is just not consistent enough to perform any semi-serious HR based training. I have worn an old analog Polar cheststrap, and watch on my other arm for all outdoor runs. About half the time, the TT will read 5 or 10 beats low. A few times, it would suddenly be low by 50% or more. Once, it was when I was running toward the low sun, and maybe some sunlight slipped under the (tight) wristband, through my pale winter skin. I have a high, for my age, maximum HR of 180. I’ve never seen the TT reach above 170, while the polar has confirmed 180. When your blasting yourself at these levels, and the lady in your headset thinks you’re at half that and is yelling, “Push it!”, one is inspired to find a new coach. I find that the heart rate zones are meaningless and useless, when using the OHRM. And these results are for running. On a rowing machine, for more obvious reasons, it NEVER comes close to working.

    Having flunked the OHRM like that, I still think it has value in tracking 24/7 low level rates, overnight patterns, and resting HR values. Still nice, but overrated for fitness purposes. As an EE with much measurement technology experience, I think the OHRM is a very tough way to measure heart rate. A very tiny signal with a wildly varying noise background, requiring complex estimation algorithms to deliver some result. It may be the best of the bunch, but I doubt that any of them will ever work very well in strenuous situations. It will never be as reliable as a chest strap ECG reader that simply picks up a loud electrical pulse and counts it directly.

    So, speaking of chest straps, my ace in the hole, backup plan, was to resort to an external chest strap, which TT says will work. With such a poor OHRM, I think maybe they should include these for free, but whatever. I did notice that there are some straps that are waterproof and talk to some gym machines (Polar H7), which the TT strap did not, so I leaned that way. Then, I heard, on the TT message board, that the H7 disconnects and drops out frequently, with the Spark. Looking further into their list of compatible HR strap monitors, I found that the two Mios on the list are optical wrist HR monitors, that the Wahoo strap listed is no longer available, that the new Wahoo Tickr doesn’t work, and that basically, there is no way to tell if there is ANY off brand HR strap that will work with the Spark. One person on the message board said that his Suunto Smart Strap worked. It is not on the TT list. I wrote TT directly. They replied that they haven’t received enough complaints to consider it an issue. I still don’t know how to proceed. I would hope the TT brand strap will work. Seems that they should admit that their strap Bluetooth connection is incompatible with anything else out there. Be nice if it would just work better with more options.

    So, two out of the big three get A-, and HR gets a D. Will give it a C when the chest strap situation is worked out. There are lots of miscellaneous features which I find good, acceptable, or could be improved but not losing sleep over. Bluetooth connection to my Android Nexus7 is very temperamental. Doesn’t seem to automatically sync at all. Need to re-pair every time, and try several times each time. Could do better there. And if it could do better there, then why not have a working Bluetooth connection to my laptop?? When one wants to sync up and download data there, they have to remove the watch, attach the somewhat odd cable, and plug into a USB. Granted, we need to charge the battery also, but not every time.

    So that’s my take. Not as stellar as DCR’s review, but I’ll be keeping the watch. Sooner or later I’ll get a chest strap working, and then it’ll finally do what it needs to do for me. And it really is an awesome idea and potential. GPS, HRM and music, on a wristwatch and a couple lightweight wireless accessories. I think a big improvement on having to carry a heavy phone on runs.

    • DougM

      Oh, and another annoying thing is the treadmill calibration. I’ve tried a few times, and the calibration is off by from 50% to 100%. Either I’m running at 3mph, or 14mph when the treadmill has been set at 7.5. I can’t imagine how an accelerometer on your wrist could tell one anything about “stationary speed” as one gets on a treadmill, but what baffles me is why they try to do it that way. Why not allow calibration or editing of the data on the website record? Something needs to be done better here.

    • “So, speaking of chest straps, …”

      My Wahoo TICKR X (now) works with my TomTom Spark Cardio+Music, and I posted about it in the TomTom discussion forum.
      link to en.discussions.tomtom.com

    • For me the whole point of the watch is to ditch the chest strap – not expecting any time soon, judging by DC’s excellent reviews.
      iphone + apps does excellent monitoring of steps, distance while walk/run and sleep and works well with bluetooth headphones.
      ONLY advantage of watch, any watch, is HR without chest strap

    • Gl00

      Regarding HR straps: you probably noticed that the belts noted as incompatible all offer extra functions from your basic chest strap (and the H7 offers these extra functions only if you have a compatible Polar watch).
      I have issues with the combo H7+Spark, but my other straps when paired with the spark, which are just dumb simple BT HR straps, work just as accurately (a tomtom and another from some supermarket brand).

      Save yourself some momey and just go with any basic chest strap, I’m pretty sure they all work.

    • DougM

      So, this cheststrap question resolved itself in an interesting way. I was browsing through Amazon and came across this.

      link to amazon.com

      Yes, that’s a Bluetooth cheststrap HRM for $5.57, and free shipping. With all my frustrations and confusing reviews, I gave it no hope of working, but ordered one anyway as a long shot. I could risk $6. The darn thing works! At first, I tested it with an Android app, and don’t know if that was needed to kick start it. But now, I just strap it on, switch the watch setting to “external”, and after a short while they find each other on their own. I don’t think one can use the watch and a separate app at the same time, but I don’t see a strong need for that. So I’m good for the time being. Pretty much knew that the optical HRM wouldn’t work, but my chest strap backup plan did. Read up to 178 on a hill sprint the other day, and it’s rock solid during weight lifting and rowing, which is like having a new function altogether. G100 probably right. Basic is better. But TT still needs work on that compatibles list.

    • TomTom Community Manager

      Hi guys, the list with compatible sensors can be found here: link to bit.ly. This list isn’t complete meaning there will be sensors available that work with the Spark / Runner 2 as well. I am sorry to hear about the issue of the combination with the Polar H7 and I will forward this information to the product team.

    • Gl00

      yes… you guys probably could replace this list with a list of “incompatible devices” or “reported to have issues” : this would probably be a lot easier to maintain and probably more useful. As far as I’m aware, it probably is limited to a couple polar belts…

  126. megan

    Any news on when you can get interval notifications through the headphones, or if there will ever be an update that will let you know your current pace, km, etc.

    • Gl00

      just out of curiosity, since I always thought that such functions were implemented in phone apps because some people would run with the phone in their pocket or something hence would not be able to read the screen: in what is this more convenient than just taking a look at the watch?

    • megan

      I’ve had the garmin forerunner 305 for years. I really like it but always found I couldn’t hear the alerts over my music. I found I was constantly looking at my watch and it was hard for me to really get into my runs. I now use my watch and a mobile app. I love that the audio coach updates me with my interval, current time, pace and split pace every km and I can just use my watch as a quick reference. It just works well for me. So ideally I could find a watch that can do both for me and I can save my data!

  127. DaG

    if you were running for longer than hour, can tomtom display time as 1:00:01 (hours:minutes:seconds) or it just displays hours and minutes like 1:01 ?
    And do you find average pace, particularly at the beginning of the run o.k?
    Thank you. Dalibor

    • The duration of your workout is in h:mm:ss format if it is the primary metric on display (i.e. occupying the main section of the session statistics screen) on the TomTom Spark. Where it is a secondary metric (i.e. occupying one of the bottom corners of that screen), it will only be shown in h:mm format.

  128. vignesh

    Hi, I tried Spark TOMTOM.I feel uncomfortable with the charging point for daily use.

  129. Erica

    I have been searching for a GPS watch with a decent wrist-based HRM and music capability. However for music, I typically use Pandora, etc. Can the Tom Tom offer music control like this outside of downloaded songs? I have also heard the gps signal can sometimes take much longer than say a Garmin..thoughts?? Thanks!

    • DougM

      Erica, I’ve never seen anything else that plays music, unless you’re looking at a smartwatch that needs some tethered phone, or something. And it will be a looong while before something is around that does a continuous wifi or cell based streaming of something like Pandora, while running through the countryside. You have to arrange your playlists, with some effort, before workouts. But I think doing it all with a wristwatch, wireless headset, and Bluetooth chest strap HRM, is awesome. Yes, that’s chest-strap. If you spend your life sitting, or mildly walking, the optical wrist HRM of any such device may work. But for any serious heart rate zone based training, you need a chest strap. TT has a feature called quick GPS, which I don’t understand. But if you update it every few days, it apparently speeds up GPS lock. Works for me. All set after a few seconds of stretching before I take off on runs. Good luck. Hope this helps.

    • Erica, the TomTom Spark Music does not and cannot connect to Pandora’s servers or that of any other music streaming service, since it has no Internet connection of its own. If you don’t want to bring storage media (e.g. on-board memory in a watch, a phone handset, etc.) with you and carry a finite amount of downloaded music, then you have to bring a mobile network connected device – which none of the running watches are in today’s market.

      There would also be little prospect of putting the specific controls (e.g. thumbs up, thumbs down, change stations) for Pandora – being just one particular streaming music service in the market – onto a running watch that is connected by Bluetooth to a phone handset that you have to bring with you on your runs. Especially so, when the watch does not even have a touch screen, but rely on four navigational buttons (and one cover-the-screen ‘button’) to control all of its functions.

      DougM, TomTom’s QuickGPSFix functionality is described here:
      link to uk.support.tomtom.com
      and the equivalent functionality for Garmin is described here:
      link to support.garmin.com

    • DougM

      Thanks ASmugDill. I was going to look it up eventually. Am curious why starting at the same location requires updates from what I thought were geosynchronous orbits, but very little matter. I think it’s a good idea for anyone to connect and refresh the watch before any run, not only to get the best most recent GPS update, but to do a soft reset on the whole watch. I noticed one time, having not connected with the wired USB (needed for soft reset), that my Bluetooth chest strap HRM started sticking badly at certain levels. For the second half of my run it’d keep telling me to “push it”, and then all of a sudden it was “too hard”, and repeat. Seemed to go away with a fresh reset, and continuous values returned. Who knows what firmware hairballs collect, without a frequent reset?

    • Luigi

      Actually, there are some wrist watch that can do the trick of streaming music: that’s the case of some Android watch, like the Samsung Galaxy Gear S or S2 with 3G connection. Even if technically they are not sport watched (they are mainly intended to be as smart watches), they pack an optical HR wrist monitor, they are also GPS/GLONASS capable and IP67/68 certified (water resistant) and they ave built-in Bluetooth 4.1 to pair with any BT earphone to play you music (either from the internal storage or from the cloud). Although I’m not sure about Pandora, they do support streaming from Google Play Music and Spotify.

    • Luigi

      You can also try another way: you can use Android Wear Smartwatches, as some of them are packed with HR wrist monitors, like the Motorola Moto 360 and some other models from LG (not sure about other brand, but I think there are more). Although the quite misleading name suggests that they’re smart, they are actually pretty quite dumb: to operate them for almost anything, you need to carry your phone with you (=they relay on the smartphone capabilities, like the GPS), i.e. the watch is a sort of remote control/display for the phone. But I think there IS a suitable setup for running: you can have a small Android phone (maybe an old one or a really cheap new one, as cheap as lower than 50$) in your pocket, start a fitness app like Endomondo (which as a companion app to be installed on the watch) and your preferred music streaming app and then simply control everything from the watch without any needs to pull out your phone from the pocket.

      Note 1: at the moment this work pretty well, but the usability can be improved: e.g. you can have only two metrics per display (let’s say one with HR and current pace and swiping to the next another one with total miles and average pace) or to change from watching on the watch your pace and HR to the music controls, you have to swipe between some watch screens (not exactly ideal when doing an intense workout/run, with your arms swinging around).

      Note 2: there ARE some a Android Wear suitable to be used standalone, as it packs it’s own GPS and internal storage for music: for sure the (new) Motorola Moto 360 Sport or the (old) Sony Smartwatch 3 (which unfortunately lacks the integrated wrist HR monitor).

  130. BPD

    As per the MS Band 2 review, I’ve been looking for a watch / band to replace my Mio Fuse – as I’m not happy with having all my data stuck on a mobile device (especially having just changed phones and having a years worth a of data stuck on a phone I know longer need / use). The device itself is superb – and I’m happy with the HRM accuracy (when compared to my Polar chest strap).

    With that in mind, I thought I’d try out the Spark Cardio+Music from TomTom. I bought 2 – one for the other half and one for me.

    We’ve both worn our Mio Fuse’s AND Sparks at the same time – for direct comparisons. I have to say, I really like the design and functionality of the Spark – it’s a doddle to use and the various training options are great – especially the ability to export the data. For me though, that’s where the positives sadly end.

    For daily tracking the step counter is terrible. My phone and Fuse and generally within a couple of hundred steps of each other, the Spark was always several thousand higher in step count…some days almost double the Fuse. It registered steps when walking fine – but it also seemed to register lots of other actions as steps – even when sat at my desk working, or driving to the office. I tried a factory reset but this made no difference.

    At no point could I ever get the device to pair with my phone. I have a Nexus 6p running the latest version of Android, the latest version of the app and the latest firmware and I simply gave up trying in the end and only used the PC software to sync. My other half had more success here – albeit it was unreliable.

    The biggest issue for me however is the HRM. I know the issue of using OHRM during weight training – my Mio will sometimes drop down a touch on the HRM reading during a heavy lift involving a strong grip – but will rapdily pick up the heart rate after releasing the weight. The TomTom was always 30 seconds or so behind. I could live with that, but when indoor cycling (spinning) and pushing high heart rates I had some real problems. Up to around 150bpm the TomTom would mirror the Mio Fuse almost perfectly (within 1bpm most of the time), however when pushing up to the 170’s and 180’s, the TomTom struggled badly. Numerous times where my Mio showed 170+bpm the TomTom would be sitting between 130 and 140 – and would stay there for up to 5 minutes before suddenly catching up again when my heart rate dropped into the 160’s again. I tried this a number of times and it repeatedly occurred. When pushing hard intervals (shorter ones or sustained) this is no good for me. The Spark seemed to really struggle at high heart rates AND struggles with a rapidly increasing heart rate. The Mio Fuse is superb in these scenarios.

    I have to say, my other half had a little more success (not perfect) – but she generally doesn’t get her heart rate as high. She was very impressed it GPS however – especially as it would mean wearing one device rather than combining her Mio with her Garmin.

    Sadly for me though, the inaccuracies with the HRM (my primary requirement) mean I have decided to return both watches. I had very high hopes and love the design but it just won’t work for me . It’s a good but I don’t think it’s quite there het.

    • Luigi

      Why not upgrade your Fuse + Garmin setup to a new Garmin with OHRM?
      There are some Garmin models in the same price range of the Spark: I also have a Fuse + Garmin Vivo Active and a TomTom Cardio Multisport (old model) and I was thinking about something like this.
      For the moment I’m waiting, since I’m not very happy with the sleep tracking of the Vivo (I usually watch some TV in bed before sleeping and a lot of time it reports it like a was already asleep) and before spending another bunch of money I want to be sure they have fixed it (same problem with FitBit Charge HR and Surge: so I think it’s a little bit tricky and we have to wait and see).
      (I know, the music feature also is appealing, but for the moment, I’m quite happy with an mp3 player embedded in the earbuds: there are absolutely not bulky and since you already need to wear them, it’s not another device to carry around. The day I’ll find a model with more decent sound, it would be perfect: mine are just a really cheap no brand, maybe the ones for example from Sony sound better).

    • BPD

      I looked at the vivosmart HR but the other half needs GPS so we had to rule that one out.

      We also need something that will do a decent job across a number of activities (weight lifting, cycling (outdoors and spinning), fitness classes and for her the addition of running.

      The only thing that came close was the FR235 but I’m not sure about it. HR accuracy from the OHRM is my primary concern and for me the Mio is very good most of the time…certainly when spinning its superb. I just wish Mio had a cloud service and that’d be perfect for me.

    • DougM

      Did you consider getting a chest strap Bluetooth HRM to go with it? That’s what saved my TT purchase, that it at least had that option. And I found a new one on Amazon for $5.75, including shipping. I tried another OHRM before the TT and was very disappointed in both. I flatly do not believe that OHRM is or can be made reliable for serious, high HR training. Fine for daily easy going tracking and sleep monitoring. But that’s it. You didn’t mention the music. To me, having good gps, strap HRM, and wireless music in such a lightweight setup is really phenomenal. They do have many many kinks to work out, like a years old treadmill calibration issue that they just seem to refuse to address. But those top three features keep it a keeper for me.

  131. BPD

    I didn’t want to go back to a chest strap. For certain training I do I find the strap would often slip no matter how tight I made it (anything with plyometrics).

    The music being built in…fantastic idea but I don’t cycle with music, spinning and gym classes theybplay music and weight lifting o do with a partner so don’t have music (just listen to what’s on in the gym).

    For spinning my HR gets very high and I can sustain it. My Mio tracks perfectly what my HR strap used to show.

    I hope TomTom can iron out the links as it would be very good then.

  132. Humayd

    Hi Ray, thanks for the great review. I’m assuming like the other Tomtom multisport devices there isn’t a multi-sport mode?

  133. Bart

    Two thumps up for Clever Training and Ray, not so much for Tom Tom. So I received the Spark from Tom Tom in October and had generally liked it alot but noticed battery problems and occasional wonky heart rate readings. Then recently upgraded to software version 1.20 and things slid downhill fast. The battery wouldn’t hold a charge when used simply as a watch with 24/7 heart rate tracking longer than 10 or 11 hours. It was supposed to last that long while gps was running. I did a hard reset several times which didn’t improve the issue but seemed to make things worse as it will now not link to the phone app. By the way, no way to downgrade the software to the previous version. Called Tom Tom and was dumbfounded they would not give me an RMA on product on the market only 4 months. FYI, Garmin will give you an RMA immediately whether you are under warranty or not. They wanted a copy of the purchase receipt. No problem, pop over to Clever Training website, download the pdf version and send it to the dude in India. Wait two days. Still no RMA. Fiinally, get an email, he wants purchase receipt, a picture of the watch, serial number, my address, phone number, and email. Well, my address, phone number, and email were on the first email that I sent, which included the receipt, and on the purchase receipt. Maybe me and India dude are having communication problems. Don’t know why they need a picture of a watch. I oblige. I still haven’t received an RMA and there is no address on Tom Tom’s website to return the watch. You are totally at the mercy of email with a dude in India.

    Conversely, I pick you the phone after the second strange email from Tom Tom wanting everything I already sent them plus a picture of the watch, and I call Clever Training. I speak to Barbara who speaks perfect English and appears to be somewhere in sunny Florida. She says I am beyond the 60 day return window but will see what she can do. Low and behold, I get an email within 10 minutes with an RMA to return too Clever Training for a new watch! That’s service and that wins customers! Hurray Clever Training! Barbara called the Brand Manager and got the deal done in ten minutes. If she were in middle America I’d hire her away from Clever Training. Tom Tom needs a lesson here. You got me away from Garmin but you probably aren’t going to keep me for long when your customer service stinks. At least in the past, don’t know about today, when I call Garmin, I get someone who speaks very good middle America English from Wichita, Kansas and I get an RMA not the run around. Clever Training are Ray are awesome, Garmin is pretty good, Tom Tom not so much. Tom Tom, listen, you may have a hit here but do not screw it up ala Motoactv and get some better customer service.

    • Bart

      Two thumbs up! It’s Friday. Sorry about the spelling.

    • Thanks Bart – always good to get great feedback on the Clever Training crew. They do great work and are super customer friendly!

      (And thanks for the support via them!)

    • Bart Bouse

      Unbelievable. I’ve already mailed the watch to Clever Training but today, 3/1/16, I get this from Tom Tom.

      Dear Bart,

      Thank you for updating the incident with your response. My name is Praful.

      The reference number for this incident is 160224-001575.

      I apologies for delay in responding to your query due to high call/email volume.

      Bart, I understand how frustrating it is when you are unable to use your watch. Please be rest assured I will be there to help you further.

      The issue might be with the hardware of the device, please provide me with below mentioned information so that I can replace your watch.
      Complete Name.
      Complete Address.
      Telephone Number.
      Email Address.
      Once we have the information above we will start the replacement process.

      I trust the information mentioned above will be helpful to get you a resolution. Please feel free to update me regarding the issue and I will be happy to assist you further.

      I’ve now sent them three emails all of which contained the purchase receipt from Clever Training that contains my name, address, and email address. Each of those emails also contains, at the bottom, my name, address, email address, office phone, cell phone, linkedin address, etc.

      Tom Tom, your customer service is the worst of any I may have ever dealt with!!

  134. John Warner

    Hi Ray, thanks a ton for the review and once again how you find time to do so many of them in such depth is a mystery to me. Anyway, I’ve had a Runner 2 Cardio + Music for 2 days now, having made a transition from a Vivo Active. I have read through all the comments trying to find some input as to why TomTom My Sports on my PC wont open without the watch being connected and once done why data cant be edited and saved without having to reconnect the watch every time. I was hoping to find that I had made a mistake with the set up somewhere and a fix/upgrade, but didn’t. If that’s how it is, then in comparison with Garmin Express it’s a real PITA. Do you know if it will remain that way, the reason for it or if changes are in the wind to enable non connected access for reference and editing? All software versions are up to date.

    • Hi John!

      You can’t open the main app and get any useful functions without the watch connected – but you can actually open the ‘Activities’ folder via the shortcut if you right click in your task bar. This is interesting, because if you want to re-export out in a different format, you can double-click on the TomTom Activity sport file from your activity. However, you can’t change the export settings without it connected. So I suppose it’s somewhat a catch-22.

      (P.S. – Thanks for the support!)

    • John Warner

      Thanks Ray. I tried as you suggest but don’t see an option for Activities, nor can I find the list of file type options for export. However, having posted link to mysports.tomtom.com to the Google Bookmark Bar it does open the App without the watch connected and one can navigate within it. A bit of a long way round. The version I have is the latest as far as I know, downloaded the from the website yesterday. It looks different to the shots in your review.

    • gl00

      Hi John,

      Ray is probably not aware of that but Tomtom is changing the way the transfers work little by little and the website is evolving slowly.

      They recently moved the export settings from the Mysports connect app to the website (there is actually a big button in the app that should bring you directly there if you have the latest version…) in case you didn’t find it already, go to mysports website, click on your ID (top right corner), click settings and you’ll see the app and export tab appear.

      there, simply click on what file types you want to export, what websites you want to connect etc… and from then on, each time you connect your watch to your PC, all these things will be automatically exported.

      do not hesitate to go directly to tomtom user forums or FAQ if you have any more questions, there are a bunch of people who can help over there 😉

    • Gerhard

      The PC program only transfers activities (and factory resets the watch). Activities are only viewed on the MySports site.
      In contrast, at least the Android app has a local viewer. (Limited, but works OK. There are alternatives.)

      If you have synced to the phone already, you must first copt .ttbin to the computer, then ‘reimport by doubleclicking with watch connected’.

    • DougM

      Don’t know if I included it in my comment above, but I have an Android device where it syncs and transfers data automatically via Bluetooth. What I don’t get is, why won’t it transfer in the same way to my PC, which also has Bluetooth. I know it needs to be charged now and then, with a plug. But for everything else … ?

  135. Gerhard

    My summary/review of the device.

    I was disappointed with the mediocre GPS in my Garmin 920XT, heard good things about the TomTom GPS and really liked the watch when I tested it in a store and got a Spark Cardio when I got a buyer for the 920XT.

    However, while want to like the Spark, I find that the TomTom is not doing the job for me, it is ultimately annoying. There is so much more potential. I returned it, may come back if there are improvements. (Will probably get a new battery for my ForeRunner 305 as I see no good alternative.)

    What I like:
    * The GPS is often accurate
    * The watch is small and light
    * The screen is quite OK and relative well used.
    * Both vibration and sound
    * Optical HR could be convenient
    * Phone BT connectivity enables QuickFix and activity details
    * Better pricing than competitors

    What I do not like:
    * GPS accuracy is good for 90% but can be worse than the 920XT in some situations. The Spark cannot be trusted.
    * No cadence for running
    * No dedicated lap button. Manual lap mode can give you ‘touch screen’ to get laps but that is less accurate and do not work with gloves (but occasionally with wet jackets).
    * Very limiting and frustrating watch SW (more below)
    * Annoying bugs (more below), some have workaround.
    * Optical HR do not work well for me when running. OHR is OK on ‘easy’ activities, but when I increase the effort it fails miserably. (I wear the spark partly covered with sweater/glove to keep the arm warm.) It is not comfortable to have the strap that close.
    * While the price is lower, the watch is not usable and not giving value for the money. With better SW, the watch would be a bargain for a higher price.

    * Display ‘freezes’ for me in about every 3rd activity, it stops updating until button is pressed
    * Syncing to phone only working sporadically. There is a workaround to open a menu to re sync, not working well for me
    * Device occasionally freezes, connect to USB to release
    * Pace is often way off from the actual pace. Lap pace is OK.
    * Seemingly incompatibility with some HR belts like Polar H7 and Wahoo Tickr.

    SW limitations:
    * Recording cannot be started if no GPS/HR lock. It should be my choice if I can give up accuracy the first meters.
    * No lap button. Should be available in all modes (touch screen but rather long press right).
    * Summary for lap is number and pace/speed only, not time or distance.
    * No information for previous laps (except in stopwatch mode).
    * Average pace/speed for a configurable time/distance (like pace last km)
    * Only one function at a time: Either manual laps or autolap or intervals or zones or ‘race this’. It also means that you cannot end intervals with lap, so run a lap+button, then 60s rest is not directly supported. For me it means that I only can use manual laps, other functions are not usable. It should be possible to activate more than one at a time.
    * No cadence when running
    * Night mode is always on only. Should be mode to light when events occurs and button is pressed
    * Pace/Speed also using the acceleratormeter, like Suunto “Fused speed”
    * Display is very limited with one changeable field only. However, the GPS/HR/battery status is not always necessary, should be option to use that row for two fields.
    * As there are no “pages” with configuration, all data is stepped through in main display. I at least want to hide information there like calories and pulse zone.
    * A little dull time display.

    The SW limitations should be easy to fix (display is probably the hardest), but TomTom has not done much to existing devices, so I have no confidence in improvements.

    Other improvements I would like to see, most requires new HW:
    * Micro usb or usb-c connector, I dont like the cradle
    * Custom apps:
    – watch faces, interactive widgets
    – data fields
    * HR retransmit
    * Barometer, better elevation
    * MySports Race configure, custom activities
    * If there is a optical HR and 24/7, the pulse should be visible, both last recorded and force updated.

    Other improvements – not my wish, just listing what other has asked for:
    * Foot pod support (no plan myself)
    * See better activity summary on device (sync to phone better, except I want some lap info when running)
    * MySports is poor, but there is autosync to Strava etc
    * Tracker inaccurate, very little information. (Only max HR with 24/7 tracking, and the HR tracking is bad for me.)
    * Sleep tracking has no details
    * Auto pause
    * Treadmill accuracy (but if fused speed is implemented, this should be better too)
    * Swimming accuracy, also no lap button
    * “Map” or breadcrumbs (I expect to bring a phone if I need that).

    The store I went to had not put the Spark on display as they had many unsold gen1 devices. The Spark price is also dropping. There are many TomTom on sale on auctioning sites. It seems like I am not the only one to be unsatisfied. The watch has so much potential. I would love to improve the SW myself.

    I would be very interested if TomTom made an Android (Wear) device: TomTom hardware with customizable SW:

    The Spark Cardio is half the price of the Garmin 920XT so a direct comparison is not fair. The TomTom advantage is sleekness and occasionally better GPS, the 920XT is better at everything else.

    • Jeffrey

      Gerard – Excellent Summary on the Spark. You listed out most of the Pros and Cons that I have also experienced with the watch. For me, I also owned a Fenix 3 but really loved the idea of having HR and Music all in one on a single device. Hence, I brought the Spark. However, as you mentioned, the biggest let down for me was in accuracy of the instant pace, it’s just way off compare to my Garmin Fenix device. Also, GPS seems accurate on most parts but I see some small portions of the tracks showing way off on my runs. Also, the limitation of a display customization of metrics is a huge let down.
      This device does have lots of potential if these short comings in SW can be fixed. But given TomTom’s track record, these issues may never materialize.

  136. Mike

    Okay Tom Tom, where are the colored straps? Its been a few months!!!!!!

    • ASmugDill

      You can order them from TomTom: link to tomtom.com

      Caveat: “Please allow 4 to 6 weeks for shipping and delivery.”

      Apart from the black one, which someone has reported receiving on the TomTom discussion forum (link to en.discussions.tomtom.com), the other colours may yet be waiting for mommy to meet daddy in order to be made.

    • John Warner

      I’ve had one for less than a week and am done with it and My Sports. In my opinion its the bottom of the pile and have reverted to my Garmin VivoActive. Its for sale now and deep regrets at having wasted money on it.

    • Mike

      Those seem to be UK at least UK dollars. I need US.

  137. Luciano

    Hi all,

    And thanks for your reviews Ray.

    I got the watch yesterday and off I went Today for my first test run on the treadmill (Still a bit cold for me here in London). I had the same issue as already mentioned by many other people, the distance, speed, pace etc. is way off. Luckily it is possible to adjust the distance and during the run we can still see all the values on the treadmill display.
    The good news is that the HR was very accurate, compared to the one measured by the treadmill handles.
    The other good point was the music, the Tomtom paired with the mpow swift headset worked flawlessly
    So, looking forward to my first run by the river and hope that distance, pace etc. will be measured correctly.

  138. monty

    Hi all

    Seems like just the watch I am looking for tight now.
    Thanks for the review
    I have one question pertaining to the two strap lengths. I am a big boy and was wondering, when they quote the length of the straps, if it is the total length (including the watch unit) or if it is the actual length of the straps. The Garmin 235 measures roughly 25cm (total, including the face) and that fits only just. If the Tomtom measures 20 odd cm at the most, including the face, it will definitely be too small.
    Thank you for your input.

    • Gerhard

      You measure the wrist on the inside, so it includes the watch unit
      link to tomtom.com
      I have wide but thin wrists, circumference 175mm and had like 40mm extra strap which suggests that max size is slightly more than 206mm.

  139. Jules

    To all at TomTom

    To echo a number of others here and several major web reviews, a key issue for me is the inability to change the clock screen. Most other watches give 3-4 options.

    If TT can change this to show the time (preferably with seconds), battery remaining (seems v fiddly to have to go two levels into the menu to check this) and the date, I would be sold.

    It’s a nice looking watch, especially with the interchangeable coloured straps, but the above holds it back in terms of everyday wearability.

    I’ll be placing my order if this gets fixed!

    • James

      I would agree with that! I would like to be able to select metrics to go on the clock face like you can with the activity face. I would like to be able to look down at my watch and get the time, current heart rate, and daily step count. I’m sure others would like to choose what metrics they are most interested in. Thanks!

    • As with the Garmin Forerunner 235, which is another GPS running watch with an optical HRM, readings for 24×7 heart rate tracking are not taken even remotely as frequently as one-second intervals. In particular, the TomTom Spark Cardio takes HR readings for the purpose of 24×7 HR tracking at ten-minute intervals (on the hour, then at ten past, and so on).

      Therefore, it would make no sense to expect to be able to see, on either the FR235’s or the TomTom Spark Cardio’s watch face or clock screen, the user’s current heart rate at a glance without deliberate action to trigger activation of the optical HR sensor (cf. “look down at my watch and get”, without pressing any buttons or otherwise signalling to the watch that the current HR is being requested). I don’t think you’d want to just see the most recent HR reading taken up to ten minutes ago.

      Conceivably the TomTom Spark Cardio can try to use accelerometer data to detect wrist turns toward the user (which is something the FR235 does), and trigger per-second HR readings for the next minute or so (which is something the FR235 doesn’t do without the user’s deliberate manual intervention by button-presses), but then you’d be asking for a far-from-trivial change to the firmware, and I’m sure TomTom is not keen for a ‘feature upgrade’ that would consume battery power unnecessarily due all the false positives throughout the day where the user is not actually looking to check his/her current heart rate. Better risk the minor inconvenience of requiring the user to manually request the HR reading by pressing buttons, than give rise to real complaints about compromised battery life.

      Speaking on choosing metrics for the watch face, you cannot do that on the FR235 out-of-the-box, without either developing your own Connect IQ watch face (and coding your selection of metrics in it), or using what someone else has developed and hoping you’re lucky enough that it just so matches what you want. I just cannot see TomTom putting in an equivalent platform for its Spark range as a firmware upgrade. If the company is going to bother at all, I think it will put it in an upgrade range of watch models, and charge you a premium for the new ‘advanced’ feature because it is desirable.

  140. Is anyone else having an issue with heart rate not registering after you get sweaty? I’ve read and re-read how and where to wear the watch, however it seems about 10-15 minutes into my workout (when I get really sweaty) the heart rate isn’t accurate at all (i.e. it stays in the 70-85 BPM range when I know I’m in the 150s to 160s). I’m disappointed in this, but haven’t heard anyone else mention it. I also talked to the friend who convinced me to buy the watch because she loves it and she doesn’t seem to have this issue (and she’s a sweaty workout person like I am)…maybe I have a defective unit? Any advice or feedback is appreciated!


    • Matthew

      Not for me personally…and I’m a sweaty bastard when I work out.

    • Good to hear! I really do think I have a defective unit with the way it hangs – it mostly ‘sticks’ at 86 bpm for my entire 45-60 minute workout. I’m pretty disappointed in 2 calls I just had with TomTom Customer Support. The first customer service representative told me that there is a software fix coming in about a week and to just wait and don’t worry – this was before he even knew which watch I own or the exact issue (all I had said was I was having issues with my heart rate on my watch).

      I called back because it seemed that the first rep was only concerned with getting me off the phone as quickly as possible and the new representative told me that it is my sweat interfering with the heart rate reading and that there wasn’t anything I could do about it. I find this extremely odd for a few reasons. First because my good friend has this watch and sweats just as much if not more than I do and her heart rate reading seems pretty accurate (we’ve compared to my old Garmin heart rate watch). Also, no one else online has said in any review or feedback that their heart rate is being affected by sweat – seems a little silly that a fitness watch supposed to be worn during working out (when people sweat most) wouldn’t work if it got sweat on it. I feel like I may have a defective watch since others aren’t experiencing this issue. The representative told me they cannot exchange my watch because I’ve had it over 30 days (I’ve had it about 40 days). I asked to talk to a manager and they said they’ll have to call me back in 2 hours!

      This is my first TomTom product and I’m not too happy with it at this point. Bummer too b/c I was looking forward to the music/bluetooth headset part!

    • Doug

      Optical wrist heart rate monitors are very controversial, in general. There are some who claim them to be superior in performance and accuracy to a chest strap, and many who claim the opposite. I started with a Fitbit Surge. I returned it because the OHRM was useless for me. Always reading far below what it should, sweaty or not, but usually sweaty. I tried a Tomtom Spark, based largely upon this review, which shows excellent HRM correlation. But unfortunately, for me, it’s not much better than the Surge. The thing that sold me on the Tomtom, and the only reason I kept it, is that it has the option of utilizing a Bluetooth chest strap HRM. That was my backup plan, what I had to resort to, and what works very well for me now. As an electronics designer of a variety of measurement systems, I can confidently say that OHRM is far more difficult to make work, than is ECG style (chest strap) HRM. They may eventually get it right, but due to apparently subtle differences in wrist physiology, it works well for some, and not at all for others. And none of these companies could care less.

    • Luigi

      Why not try to swap your unit with your friend for a workout?
      If yours won’t work with her and hers will work with you, then it’s the watch and the warranty must cover it.
      If yours work with her and hers not with you, then it’s definitely something else (maybe your sweat, your wrist morphology, etc.).

    • Good call Luigi – however, we live 300 miles from one another. I do see her a few times a year so maybe I’ll try hers when I see her next!

    • oscar

      I had exactly the same problem with my runner 2 cardio in relation to the measurement of the pulses. I sent my unit for service of tomtom and they have given me a new unit

  141. Michael McParlane

    I bought one of these watches earlier this year, (subsequently returned), and had considerable trouble trying to calibrate with a treadmill, on the fly, following the instructions and phone conversations with a tech. First, the mileage didn’t register at all after input on three different occasions, and another attempt on another day repeatedly doubled the mileage that I entered. I was told that “a lot of people had brought up that issue…” Why on earth would they put out a product with this built-in failure? When it came to intervals, the miles could only be entered with one digit after the whole number, i.e. 1, 1.5, or 2.0; it wasn’t possible to enter 1.25, or 1.75.

  142. Timothy Berkey

    Well, I couldn’t make up my mind between this and the new Garmin Vivo HR, but the Garmin won’t be out for another 6-8 weeks or so. I decided to order the TomTom (from Clever Training, of course) and see how it works for me. It appears that people either really like it, or have already returned it. Many of those returns have been for reasons that aren’t relevant to me, such as using as an activity monitor, etc.

    If it doesn’t work out, it will go back and (hopefully) the Garmin will be what I need.

      EDIT: Have to admit, I’m disappointed by my first experience with Clever Training, so far. The item came with “Free 5-7 Day Shipping”, so I went with that. Well, I ordered on a Tuesday, the item didn’t ship until late Friday afternoon, and the estimated arrival time (on FedEx’s site) is NEXT Saturday. That’s 11 days to get a small package from Florida to Michigan. That is just not right, in 2016. I’m hoping that future experiences will be a notch or three up from this!

    • Hi Tim-

      First, thanks for the support.

      I checked with the Clever Training folks. I think you misunderstood the wording. When you ordered, the 5-7 day estimate was when it would be in-stock (as shown on your receipt). Meaning, the product was back-ordered. So that’s until it gets to them.

      After that, you selected free shipping, which will vary based on where you are in the states relative to Clever Training (located in Florida).

      Hi, Ray. Thanks for taking the time; that is appreciated.

      I’m not sure where that info came from, but I am 100% sure that when I went through the order, it said “In Stock”. That was the reason that I went with this watch, over waiting for the Garmin unit. Either way, it’s not a major deal, just a mild inconvenience, as when you finally make the purchase, you want it now! First world problems, eh? 🙂

      Thanks, again. I know you are an insanely busy person and for you to get involved like this means the world to me, as a consumer.

    Hi Ray, Thanks for the review, Is there any way the stopwatch can be used while using other modes?

    • Humayd,

      Stopwatch is a separate activity mode in its own right on the TomTom Spark, and hence mutually exclusive with any other activity mode. However, I’m pretty sure Duration (i.e. time elapsed since the start of a tracked activity) is a metric available in all other activity modes, and Laps→Manual a training option within each if you wish to record times for manually marked laps (using the same cover-the-watch-screen trigger as in Stopwatch mode).

      Which feature or metric are you specifically after? You cannot see a list of times for previous laps during a workout in any other activity mode than Stopwatch, but that’s about it, if I recall correctly.

    I mentioned in an earlier post that I had returned this watch for various failures, but I just discovered, (too late for a refund from Apple), that TomTom charges you for the three “sample” songs on the watch! Okay it’s not a fortune, but multiply that by the number of people buying this unit, and it probably amounts to tens of thousands of dollars.

      Not here in the US, as far as I can tell. Got one techno sample that I quickly overwrote, but don’t recall getting a bill for it. Do I get a partial refund for erasing it??

    • Michael McParlane

      I got a bill on my iTunes account for the three songs after I downloaded the TomTom watch app.

    • That’s increda-weird. Especially because the packaging states those songs come with it.

      I don’t ever remember seeing a bill either, and I’m certain by now there would be 2,283 ticked off comments if so.

      Not saying you didn’t get charged (obviously, you did), just really curious on how that would even occur. I’m not even sure there are API ties to even have a 3rd party app on the desktop trigger a iTunes music purchase.

    • Michael McParlane

      That’s what I thought, Ray. So you can imagine my surprise, (and anger), when I saw this bill. I’m now trying the dispute route with PayPal, as Apple can’t help due to the time that’s passed. That, on top of the fact that the watch was a disappointment in the aforementioned areas, and being told by the techies that “…we have had a lot of complaints about this issue, and we’re working on it.”

    • Michael McParlane

      Well, I have a confession and apology to make: Turns out that my daughter ordered those songs, and I erroneously assumed that they were the three songs that came with the app, because they showed up after the free TomTom listing on my iTunes statement.

      Sorry for the misleading comment, and I apologize to TomTom for any misunderstanding about the music.

    • Haha…no worries! Good to find out the cause there!
