FitBit Zip In-Depth Review

IMG_2016

Here’s a fun fact to start out with: The FitBit Zip is actually probably the only product where I’ve written the review after over a year of use with the device.  Well, two devices actually.  But, more on what happened to the first one later.  Still, given the market for activity trackers continues to heat up, and I continue to try and track the activity trackers – I wanted to circle back to this little one first before I publish a number of other activity tracker reviews over the next few weeks (Withings Pulse, Polar Loop, and some others).  Think of this as a bit of a ‘baseline’ from which to start from.

Just to be clear, in the case of the FitBit Zip, I went out and purchased it myself.  Well, both of them myself.   I’ve used FitBit devices for over 3 years now (as my account shows in some screenshots), so by now I have a reasonably good understanding of the platform.  Thus, with that, a review.

Lastly, at the end of the day keep in mind I’m just like any other regular athlete out there. I write these reviews because I’m inherently a curious person with a technology background, and thus I try and be as complete as I can. But, if I’ve missed something or if you spot something that doesn’t quite jive – just let me know and I’ll be happy to get it all sorted out. Also, because the technology world constantly changes, I try and go back and update these reviews as new features and functionality are added – or if bugs are fixed.

So – with that intro, let’s get into things.

Unboxing:

To start with, you’ll find the FitBit zip sealed inside a plastic shell with paper innards.

IMG_1997

Flipping it over the back shows you how the device can be worn, as well as what type of data it collects.  Don’t worry, by time you’re done with this review you’ll be rather familiar with all that.

IMG_1998

Taking the insides and placing them out of the plastic casing, you’ll find a little hatch that includes the battery, battery cover opener, FitBit clip-on holder, and a Bluetooth Smart USB stick for your computer.

IMG_2009

IMG_2013

Here’s all the pieces laid out accordingly:

IMG_2016

The little rubber Zip holder allows you to slide the Zip itself into it, and then it keeps it well protected.  In the past year wearing it almost every day I never had an issue with it falling out of the secure rubber casing.

IMG_2022

here’s the Zip itself.  It’s roughly the size of a few quarters stacked on top of each other.

IMG_2023

Next we have the CR2025 battery that goes into the Zip.  This battery will last you about 6 months in my experience.  At which point you simply replace it with another $2-3 battery.

IMG_2028

Speaking of replacing the battery, you’ve got the little battery replacement key.  It’s funny, most companies just make you use a house key or credit card or the like – it’s fairly nice that FitBit actually included a tiny tool for it.

IMG_2029

Next we’ve got the Bluetooth Smart USB stick.  This is if you have a Windows PC (or an older Mac) and don’t use the phone to connect to the device for downloads.  For most people, you’ll never use this.

IMG_2031

Here’s the instructions:

IMG_2033

With that, let’s get onto how it sizes up against other units on the market.

Size & Location Placement Comparisons:

IMG_4559

With so many devices on the market these days, I figured it’s probably worthwhile showing a bit of a comparison of where things stand.  Ultimately, virtually all on-market devices today fall into one of two camps: Wrist based or belt/clip based.  First up, the belt/clip based units.

Today, the most common units in this category would be the variety of FitBit units (Ultra, One, Zip), as well as the Withings Pulse, and then a small collection of units from Sportline as well:

IMG_4560

IMG_4570

As you can clearly see, the FitBit Zip is amongst the smallest footprints out there.  Though a tiny bit wider than the Ultra, it’s much shorter.  You’ll note that the newer FitBit units and the Pulse all use a rubberized case.  This is important as it keeps the unit from slipping out and falling into the toilet (trust me, been there, done that).  It provides that tiny bit of traction that’s required.

Next, while not covered in this review are some of the wrist based units.  Below you can se the FitBit Flex (bottom), Nike Fuelband (middle), and newly released Polar Loop (top):

IMG_4568

IMG_4564

Size-wise these are all reasonably similar, with the Flex being the thinnest/smallest, and the Fuelband and Loop being pretty darn similar:
IMG_4562

I didn’t include the below Basis B1 in this show, merely because it’s a full-on watch as well, and has far more metrics it’s recording (such as sweat and heart rate).  So it’s sorta like comparing an aircraft carrier to a fishing boat.

IMG_2358_thumb

Note, there are some units out there (such as BodyMedia) that attach to your upper arm.  I’m not including them here for two reasons.  First is that I find most of these cumbersome to wear.  But second is that they aren’t actually in the exact same market as the units above.  Most of the units above are more concerned with measuring simple day to day activity such as walking.  Whereas some of the more advanced (which, may be a stretch of that term) upper-arm based units measure sweat and/or heart rate in the drive to get more detailed information about calorie burn.

Initial Setup and Configuration:

Before we get to using the device, we’ll need to add the included battery.  Don’t worry, it only takes a second. Grab that little tool that came with it.  In the event you managed to somehow inexplicably lose said tool in the last 4 minutes since unpacking, just use a coin, credit card, or key.

IMG_2035

Once opened, go ahead and plop the coin cell battery into the device, then put the cover back on again:

IMG_2036

Give it a tap, and the little smiley face should pop-up.  That’s it – it’s ready to roll!

IMG_2039

Next, we’ll need to pair to to our phone.  I’m running through the iPhone version here (which requires an iPhone 4s or higher due to Bluetooth Smart requirements), but you can also do the same on the Android version of the app.

To start, you’ll go ahead and search for a new device:

IMG_3269

Once you tell it which type of device to look for, go ahead and tap the screen to wake it up.  Shortly therafter, it’ll find the Zip:

IMG_3272 IMG_3273

Next, you’ll go ahead and get a four-digit code sent to the Zip.  Simply type what you see on the screen into the phone:

IMG_3274 IMG_3275

Following that it’ll link up the FitBit and you’ll soon be on your way:

IMG_3276 IMG_3277

Day to Day Use & Recording of Activity:

When it comes to usage, the FitBit Zip is probably the silly-easiest unit on the market to use.  Really, there’s only a single ‘button’, which isn’t really a button at all.  It’s just a screen you tap.   First up though, is wearing it.  For me, I wear it on my pants waistband, just under the belt.  It’s virtually invisible in this location.  So much so that I’ve completely forgotten it’s there numerous times.

IMG_4553

This aspect of completely forgetting about it is further emphasized by the fact that the battery lasts about 5-6 months (it was roughly 5.5 moths for me).  At which point you just pop off the back and swap it out with a CR2025 replaceable battery for $2-3.

When it comes to other locations that you can wear the device, here’s what FitBit recommends:

ZipWear

By default once touched the Zip will display a smiley face indicating your progress on the day’s goals, such as below:

IMG_5311

Then, if you tap it again, it’ll show the time.  The time is automatically synchronized with your phone’s time zone.  This is especially handy for me in that I’m constantly crossing time zones for work travel.

IMG_5312

You can then tap the screen to iterate through the display fields showing metrics it records, starting with Steps:

IMG_5313

Then distance.  I’ve set it to display in miles, but you can switch it to kilometers (metric):

IMG_5314

Next are calories burned over the course of the day.  This takes into account your baseline calorie burn just for being alive.

IMG_5315

Finally, it gives you a little smiley face too:

IMG_4582

The unit will automatically shut off the display after a few minutes.  To wake it up you just tap it upside the smiley-face head.

IMG_5308

Now, it’s probably worth noting that it doesn’t record and/or display certain other metrics, which are as follows:

Stairs/Floors: Only the FitBit One, Force and now retired Ultra records this.  Mr. Zip does not (nor Flex).

- Sleep: Only the Fitbit One, Force, Flex, and Ultra do this as well. Again, zip for Mr. Zip.

- Pulse: No FitBit units on the market record this, but I wanted to point it out.

- Alarms: The Zip doesn’t have any vibration/beeping or other noise-making capabilities. It’s all about being a quiet partner, not a noise-maker.

Finally, it doesn’t record/display any sort of mythical pony currency like Fuel points or the like.  It just gives you straight calories as your unit of work measurement.

Uploading data to/via your phone:

Uploading all of this treasured data to your phone is just as silly easy as using the unit.  In fact, there’s really only one action you’ll ever do with the Fitbit.  Which is simply hitting it.  So in this case, we again give it a love-tap and after opening up the phone app and then clicking the little ‘refresh’ icon:

IMG_3279

Now, the upload process doesn’t tend to be the fastest cat in the house.  If you’re just syncing a day’s worth of data it’ll upload pretty quickly (perhaps 30 seconds).  But, if you’re syncing a week or two’s worth of data I find it takes a heck of a long time (many minutes).

IMG_3280

Further, when it does take that long time the data doesn’t seem to appear directly on the app itself immediately.  Rather it seems to be processed by some backend web service, and then enumerated onto your app.  This idea is further supported by the fact that you can’t actually sync to the device without internet connectivity.  For example, on a plane:

IMG_3240

Nonetheless, I’d agree that the scenario where you’d want to sync to your phone to upload but lack uploading interwebs…is probably somewhat rare.

Finally, you can also enable what’s known as ‘Background Sync’, which will automatically occasionally connect to your FitBit while the FitBit app is running and try and grab data.  There’s a small hit on battery here (mostly on your phone), though with all the other junk I’ve got running on my phone it’s a bit difficult to figure out how bad that hit is exactly.

IMG_3251

There exists FitBit apps for both Android and iOS, though it requires a phone that supports Bluetooth Smart (Bluetooth 4.0).  On the iOS side that’s any iPhone from the 4s and newer.  On the Android side, that’s a bit of a complex question to answer, and it’s better to look right at FitBit’s site.  Finally, while there is a 3rd party FitBit app for the Windows Phone ecosystem, it doesn’t actually enable uploading data.  Rather, it just displays uploaded data (and, it’s nearly as fluid as the FitBit provided apps):

wp_ss_20131029_0003 wp_ss_20131029_0002

To upload data to the Windows Phone you’ll need to use your PC (or Mac) to get the data to your account.  Once that’s done it’ll go ahead and show up on your phone app.

Uploading the data onto your computer:

In addition to using your phone (for supported phones), you can also upload via your computer.  FitBit provides a small USB adapter in every box that you can plug into your computer and then connect to the FitBit device.  This in turn connects to the web service to upload your data.  Nothing more, nothing less.

image

Once you’ve got the software installed you’ll simply configure your FitBit account:

image

Then you’ll do much the same procedure as before with your phone by giving your FitBit a quick tap to wake it up.  The unit will then sync with the PC/Mac software and upload the data to your account:

image

You aren’t able to use the app to display your data, rather, it’s just a conduit.  To display the data you’ll need to go onto the website…which, I conveniently talk about next.

The FitBit Dashboard:

The FitBit Dashboard is your primary go-to point for viewing data about your existence within the FitBit ecosystem. I’m going to walk through the newer/beta dashboard UI (user interface) layout, rather than go through the older one – since that’ll like disappear over time anyway.

Below, is the default view in the dashboard, showing a bunch of different metrics that the Zip tracks (or, that you can log manually).

image

At the top, you can change the day of the week by scrolling left to right:

image

For each one of these dashboard ‘widgets’, you can hover over it to get a % of goal number displayed:

image

You’ll see towards the bottom the ability to earn ‘badges’. These badges are awarded based on hitting certain milestones – such as accomplishing a number of stairs or steps in a given day.

image

The FitBit dashboard is designed show you input versus output in certain widgets. In this case, that input being food you consume. Today all of the activity trackers out there require you to manually enter that food using a massive food database with calorie metrics built in. This tends to work great if you go to Subway and get a 6” turkey sub. But it falls apart entirely when I go to a friend or family’s house and have their special dish du jour – or most non-chain restaurants.

Nonetheless, the capability is there. And I’ve found with similar databases that it can be valuable as a bit of a gut-check (no pun intended) on rough calorie consumption. And, if you do have absolute knowledge of your caloric intake, then you can likely get quite close.

image

Because the FitBit Zip doesn’t track sleep metrics within the device, you can instead manually enter that information which will then show up in the online dashboard as well as phone apps.

image

Next we have the ability to tweak the display settings on the Zip itself. For example, you can enable or disable certain pages. Given how few pages there are on the Zip, I suspect most folks won’t/aren’t using this. This page also allows you to see the current firmware version, as well as battery status.

image

In addition to the web dashboard, you’ll also have access to most of the same data via your phone app. Below you can see the dashboard view for a few days:

IMG_3260 IMG_3261

I can then dive into some of these via charts on the phone app, changing the timeline as well as the displayed metric (steps/calories/etc…).

IMG_3264

Finally, in addition to all of the above, the service will e-mail you (optional) weekly with your updated stats.  For example, here’s the most recent –email I’ve received:

image

You’ll see total distance as well as calories and badges.  The badges are earned as noted above based on various milestones you hit along the way.

Data Accuracy:

Accuracy of data is a bit of a wild-wild-west when it comes to most of these activity trackers.  In fact, getting them to agree on steps is nearly impossible.  Let alone getting them to agree on distance or calorie burn.  Thus, there’s a few ways I attempt to ferret out who might be correct.

First up is a simple test that’s easy to complete: The 200 Step Test.

In this case I simply count off 100 steps and see what the number displays at the end.  I do this twice, just for fun:

Test 1: 100 steps exactly

Test 2: 107 steps

Next, I take that same test and add in a bit of a twist, a flight of stairs in the middle.  I accomplish this by simply walking 75 steps to the stairs, then up the stairs, back down two flights of stairs (60 steps in total), and back out 75 steps (total 210 steps):

Test result: 217 steps

I go up/down stairs because I’m interested to see how well it counts the steps.

As you can see, it was mixed. The first test it was spot on.  Then the second and third test it varied by 7 steps.  Now, I do these short tests merely to make a point.  Sometimes you luck out and are spot on, and other times the twists and turns of daily life changes the result.

Lastly, we’ve got a bit of a test I completed this summer between a number of units that I thought might be interesting here.  Understanding which unit is ‘correct’ is ultimately rather difficult.

image

If you take an individual data point, it can either base fairly close or fairly far away.  Deciding which is correct is really darn difficult.  For example – why was the FitBit Zip so much higher on that Tuesday than the rest?  I suspect it’s because that Tuesday I was actually riding around a bit on bikes around the city (not road-riding, just bike-share riding).  It’s interesting to see that the FitBit appears to be more sensitive to vibrations there than the Withings Pulse.  Now, in this case that may not be a bad thing to be honest.  It may get me a bit closer to actual work-effort than the Pulse, even if the medium (steps vs pedaling) is wrong.

The point here being don’t overthink the accuracy.  Focus on hitting that number (whatever that number is) day by day.  It gives you an approximation, not an exact number.  Don’t decide that you’re going to cut 50 calories from your diet because the unit said you were 50 calories low.  It is not (and most of these devices simply aren’t) within that level of accuracy.

Notes on sport tracking accuracy:

I often point out to folks that devices like the FitBit aren’t terribly great for tracking sports activities – such as running.  Either from a caloric or distance standpoint.  First off, these devices can’t actually determine how much effort you’re putting into the activity, which is one key metric for determining calorie burn.  Traditional running watches simplify this by just doing standard distance*weight type equations, using basics such as 1 Mile = 100 Calories.

And that would somewhat work in this case if the unit could actually track while running. But ultimately, it can’t.  It’s not very good at that at all.  To illustrate this, take the following run I did.  It  was a 9.25 mile run, tracked using GPS (on actually two devices, both similar distances).

IMG_5271

In the case of the FitBit, it listed as 7.36 miles (I put it on for the first time that day at the start of the run).  And, the kicker is, that’s actually including .38 miles after the run ended before I remembered to look at it (I had measured the distance I walked post-run as the cool-down on a separate file).  Thus making the distance difference even worse.

My point being, with the FitBit you’re really measuring the ‘other 23 hours of the day’, not the 1hr that you’re participating in some sort of aerobic activity.  For me, I actually remove my FitBit when I’m working out.  I’ve got plenty of other devices to track that, and really want to just better understand the other side of things.

A brief look at the FitBit One and FitBit Flex (and the new FitBit Force):

While this review is focused on the FitBit Zip, I do have, and have used as well, the One, Ultra and the Flex.  I have not used the new FitBit Force (the successor to the Flex).  I think that in general FitBit has done a really good job of bridging the marketplace across the different price ranges and wearable locations that most people fit into.  Further, they’ve done a solid job of providing a web site and service behind that to access that data.  So this section is really just a short drill-down into the options you have within that lineup.

FitBit One:

IMG_4577

The FitBit One is the successor to the older FitBit Ultra.  Me and the Ultra were best buds for quite some time, a couple years in fact.  We had a few disagreements (he left me for a toilet bowl), but largely we were happy.  The One came along and improved the situation slightly, mostly in the connectivity and form departments.  The One added wireless synchronization to your phone (the Ultra required a little charging dock), as well as added a vibration alarm.  More importantly however (in my eyes), it added a rubberized case to the outside to minimize toilet-bowl incidents.  The older Ultra was sleek as a bullet and easily slid off.

The One also has functionality where the Zip doesn’t, namely in the floor/stairs climbed arena as well as the sleep side of things.  Sleep can be interesting if you regularly wear the device to bed.  I personally find stairs less interesting because in general most people aren’t going out of their way to actually measure the number of stairs climbed per day (even in office buildings).  At least any appreciable number of stairs worth measuring.  Meaning do you really need to know that you climbed 16 stairs that day versus 32 stairs?  Neither are really numbers that make a dent compared to walking an extra 1,000 steps.  Just my ‘reality check’ opinion.

If you do plan to walk a lot of stairs, then by all means consider a unit that counts that.  But if not, I wouldn’t spend extra for that feature.

FitBit Flex:

IMG_4594

From the moment I saw the Flex last year at CES I immediately didn’t “get it”. And in fact, the vast majority of the other media outlets echoed the same opinions as well.  The problem with the Flex was that it failed to allow you to see your progress.  One of the major reasons one wears a wrist based unit over a clip/belt unit is for slightly easier access to the display.  The problem? The Flex lacks a display.  Sure, the company would argue it’s got this little five-dot LED system.  But aside from some stoplights, what other devices do you know that can usefully convey information about your movements in five dots?  I’ll help: None.

Thus ultimately I had to wear something on my wrist that only served the purpose of gathering data, rather than also encouraging me to keep aiming towards my goal that day.  In case it’s not obvious by now: I’d definitely skip the Flex.

FitBit Force:

image

Finally, the Force, which is the successor to the Flex.  This unit ‘fixes’ my major issues with the Flex by adding a display to it.  In my opinion this takes it from the non-buy category (Flex) to the purchasable category (Ultra).  However, because I haven’t had hands-on time with it yet, it’s a bit early to make that call.  There are plenty of other devices that work fine in PR/marketing materials, but suck in real life.  The thing that the Force has going for it however in this equation is that it should be largely using the same underlying code as the Ultra and Flex, and thus likely won’t be an all new venture.  Now, with wrist-based units it’s not all about code.  The Jawbone UP of the past proved that point quite nicely when it ultimately required a distribution-wide recall due to defective hardware issues.

Brief thoughts on the FitBit Aria Weight Scale:

In the scheme of reviews, I’m not entirely sure how the FitBit products ended up on the wrong-end of the review cycle timeline.  Perhaps oddly enough just because I use them daily I sorta forget about them.  Like the FitBit Zip, I bought the FitBit Aria some time ago (almost 18 months ago in fact).  And it’s been in our bathroom ever since.  I generally weigh-in on it almost every day – sometimes twice a day after runs and other longer training activities.

IMG_8200

The scale connects via WiFi to my FitBit account, and the data is automatically uploaded to the FitBit service as soon as I step off the scale:

image

Because this data is in the larger FitBit empire, it’s then available not only online, but also within the FitBit app:

IMG_3267

When it comes to body fat, I haven’t independently tested it against higher-accuracy methods out there.  In general, as you’ve seen in my past body fat scale tests – most of these devices sorta suck at body fat.  They tend to be consistent for day to day, but aren’t necessarily truly accurate.  For most folks, it will provide a general ballpark, but I also wouldn’t become obsessed with that number (body fat) either.  I don’t however see any issues with accuracy of the weight side though.

Many people ask about the differences between the FitBit and Withings Scales (given I’ve got all of them on hand).  But honestly, here’s the thing…there are really so few differences between the two.  Both are solid devices (something I can’t say about all scales these days), and both do exactly what you’d expect them to do in a consistent manner.

Further, both have open API’s and allow you to send your scale data to multiple services, and both have apps across two or more different phone platforms.  There’s no absolute and clear winner.

In general, I’d suggest that if you buy FitBit activity tracker it probably makes sense to buy a FitBit scale.  Whereas if you buy a Withings Pulse activity tracker it probably makes sense to buy a Withings Scale.  Simply because it means your data will appear in a single dashboard and a single app, and, in both cases it’ll be a bit of pinnacle of ‘working together’.

3rd Party Connectivity:

image

FitBit has always been great about allowing 3rd party apps to connect to their platform.  They’ve had an API as long as I can remember, and have had partners just as long.  This means that your data isn’t islanded away, nor is it only limited to FitBit devices.

This means that through partner apps you can feed in data from other devices, or apps.  Mostly apps actually.  In this case you can use apps such as MapMyRun or Endomondo to integrate your runs into your FitBit account.

Further, they’ve also partnered with insurance providers as well – providing a mechanism for both insurance companies and corporate wellness programs (and similar things like the Walgreens rewards program) to give you rewards for usage.  Other companies (such as Garmin) are doing similar things, but FitBit is way ahead in the game here.

Next, if you look at privacy settings, it’s incredible how much control FitBit gives you over what information is released (if any):

image

Now, my only beef is that while FitBit does offer export of data via a CSV utility, it requires the $50/year premium option to access it.  This is quite honestly pretty lame.

image

Further, this is one area where the API falls short – it doesn’t allow what’s known as ‘intraday’ data (basically the minute by minute data) to be accessed.  Rather, only the daily summaries.  Thus ensuring that nobody can circumvent FitBit. While there are some 3rd party options that try and hack away at it, most of them are well beyond complex for the average user.

Updating the firmware on your Fitbit Zip:

It should be noted that the unit does support firmware updates, and FitBit has delivered a number of those over the past year.  These updates tend to add minor items – mostly on the app side (such as sync of time zones).  The updates only take a few minutes to complete, and are done via the app.  You’ll see a notification like the below that the FitBit has a new firmware download available for it:

IMG_3251

Then, you’ll go ahead and want to place the two devices (phone + Zip) nearby each other.  At which point you can go and and start the process.

IMG_3253 IMG_3255

Once it’s done (in a couple of minutes), the unit is back to normal tracking distance and steps.

Bugs and Miscellaneous:

I generally don’t see any bugs these days with the FitBit Zip.  When it first came out I saw all sorts of weirdness, especially around uploading.  But after a year since release things are much smoother now.  About my only complaint is that it’s definitely not washing-machine proof (as I learned recently).  But, neither was another unit that went through a similar washing-machine experience (Withings Pulse).

Pros/Cons:

When it comes to activity trackers there’s a bit of an inherent pro/con around where to place it (wrist vs belt/clip).  I’m going to skip that obvious complimentary set of pros/cons and focus on the others:

Pros:

– Silly simple usage – only one action: Tap
– Connects wirelessly to phones via Bluetooth Smart
– Battery lasts 5-6 months, only costs $2-3 to replace
– Dashboard and app work well, easy to consume data
– Good 3rd party support/partnership ecosystem

Cons:

– Selection of Bluetooth Smart compatible phones is limited outside of iOS and absolutely latest Android phone units
– Doesn’t track metrics such as sleep or stairs/steps
– Step-counter accuracy seemingly varies a bit
– The export functionality is paid-only, and for $50/year

Comparison Tables:

There’s a lot of activity trackers on the market these days.  The most popular brands being FitBit, Nike, Basis, BodyMedia, and more recently, Withings and Polar.  In an effort to help you navigate that landscape a bit I’ve put together this comparison chart which talks specifically to units that I’ve tried and tested (and felt worthwhile to actually mention).  It doesn’t talk to units I haven’t tried and tested.  That’s the way all my comparison charts work: I require real-world access to the product to make the database.  I simply find that PR/marketing blurbs twist the truth a bit, so this gives you an independent place to get that data.

With that out of the way, here’s how things stand up (note you can mix and match other units beyond this pre-selected list here):

In general, if I had to recommend just a single activity tracker out there today – it would be the FitBit Zip.  It fulfills all the basics and is easy to use.  I could give it to my 96 year old grandpa and he’d be able to use it just fine for tracking his walks (he walks far more than you’d think).  From a software cleanliness standpoint the suite works well and isn’t buggy.

There are no doubt things it could do that other units do, but I’m realistic that at $59, it does just about everything I really want from a core usage standpoint.  Sure, units 2-3 times the price can measure stairs and heart rate (and even perspiration).  But for most people that just need to increase basic activity and movement, this is really the ideal unit.

By the same token, there are units half the price as well.  And those do a good job as well (more on them in another review), but just without the wireless connectivity or tiny size footprint.  I find the FitBit Zip is really the perfect balance of everything.

Now, is this for the endurance iron-distance athlete?  Yes and no.  There’s interesting data to be had in monitoring the other 20-23 hours of your day.  Especially around recovery and how much activity you’re actually doing on your recovery days (versus perceived).  However, the reality is that most of these activity trackers are really aimed more at non-endurance athletes looking to get active.  Simply looking for a bit of motivation to get up, walk the 1/3rd of a mile instead of taking some other mode of transport, and just focus on moving rather than sitting.  For that crowd, this works perfectly.

Found this review useful?  Here’s how you can help support future reviews with just a single click. Read on!

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 (especially this one, probably the longest and most detailed I’ve ever done), 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 an exclusive 10% discount across the board on all products (except clearance items).  You can pickup the FitBit Zip (or any other FitBit) from Clever Training. Then receive 10% off of everything in your cart by adding code DCR10JKW at checkout.  By doing so, you not only support the site (and all the work I do here) – but you also get a sweet discount. While this item is less than $75, if you did add something to your cart to bring it over $75, you’d get free shipping as well.

Additionally, you can also use Amazon to purchase the unit (all colors shown after clicking through to the left) or accessories (though, no discount on Amazon).  Or, anything else you pickup on Amazon helps support the site as well (socks, laundry detergent, cowbells).  If you’re outside the US, I’ve got links to all of the major individual country Amazon stores on the sidebar towards the top.  Though, Clever Training also ships there too and you get the 10% discount.

Thanks for reading!  And as always, feel free to post comments or questions in the comments section below, I’ll be happy to try and answer them as quickly as possible.  And lastly, if you felt this review was useful – I always appreciate feedback in the comments below.  Thanks!

Finally, I’ve written up a ton of helpful guides around using most of the major fitness devices, which you may find useful in getting started with the devices.  These guides are all listed on this page here.

  1. I recently purchased the fitbit one after returning a withings pulse after 2 defective units. I find that it at least encourages me to take the stairs more often

    2 Tips for the fitbit
    1. There is a 3rd party app that will sync with garmin connect -- link to fitbit.com I use this app and dont wear my fitbit while swimming/biking/running
    2. You can log a driving activity when driving and it will not count any steps while in the car. There is an android app called DriveBit that makes this easier to do

  2. Hi there,

    Though I like the look & feel of the newer dashboard, there's one thing that I find pretty annoying : widgets will only show the data of a specific day and not a period (week, month, year). Am I missing something or is it really impossible to get periodical metrics on the new dashboard ?

    Thanks !

    Thanks for the review. I have been a FitBit owner for a long time. Originally I had a classic FitBit, i.e. the first model, which I murdered with sweat. FitBit sent me an Ultra as a free replacement. I think their customer service is really excellent. Any issue I've had has been met with fairly immediate and very appropriate response. I lost my clip and sleep wrist thing for my Ultra. Replaced for free without question. I needed a new charger for my Flex, and, once again, mailed to me for free without issue.

    I note in your review above you list the location for wearing the Flex as "waist" - I think you mean "wrist." I can't imagine that many folks are wearing it other than on their wrists.

    I have to say, I really like the Flex and am not hampered by the lack of a screen - I always have my phone with me and can check the data there quite easily. The sync is virtually seamless. I also like that with the Flex I can get different colored wristbands to wear (cheesy and not functional, but sometimes I like the fun stuff too).

    I've been using a fitbit one for a while. To add on to what Kevin said, another tip for work outs is that you can manually enter any activity into the log and it will update its data. I do this for runs (I enter the time and distance from my Garmin), and also for strength training.

    I know Withings will sync with Fitbit, but I don't think the Aria will sync with services like Training Peaks. Didn't dig deep, but there doesn't seem to be much about syncing the Aria with services other than Fitbit. Hence I'd still give the nod to the Withings.

    I think that maybe you are underestimating the "stairs" facility on the fitbit one. While it does indeed count the number of stairs what this actually represents is 10 feet of elevation gained per "flight of stairs".

    Whilst out hiking this information can be really itersesting (it seems to be very accurate when compared to a GPS measurement of height gained). The diffenece this makes on the calories burned calculation also seems to be fairly substantantial.

    I have used the Nike Fuel Band for 2 months. I have been impressed with how accurate the steps/fuel points/distance are. For me, I have found when I run my 10 mile GPS measured route, the FB shows 10,000 fuel points (give or take a 100 fuel points)and the steps 20,000(give or take a 100 steps). Having run close to 400 miles over the last 2 months, the accuracy is pretty neat. Now, I will tell you that one can get fuel points for about anything. You could probably sit in a bar room all day and keep lifting your glass and amass a lot of points-not sure about the steps. It doesn't measure sleep, but at midnight it begins at zero FP. I find most mornings before getting out of bed my FP reading is from 2-20. I make an assumption that a 2 reading meant I slept pretty soundly. Kind of a fun gadget, even for a 70 yr old guy who has run over 78,000 miles over the last 37 years. I pre-ordered the Loop and plan on comparing the readings, I might become a DC Rainmaker, Junior.(:

    Ray, I remember in the past you have recommended the Zeo sleep tracker, but seeing as that company has gone the way of the Dodo, do you have a new recommendation? Many of the activity trackers also do sleep, but are some better than others, or is an app on my phone just as good?

    Reply
    • Eli replied

      What type of sleep tracking do you want? Doesn't seem like anyone truly knows what is useful to track and what isn't. All activity trackers currently out there just track based on the accelerometer so just measuring if your arm is moving or not and make assumptions based on that so doesn't seem all that useful.

      Then there is Beddit (link to beddit.com) which tracks heart rate, breathing, and movement that you just put on your bed and leave there. For athletes this could in theory allow for an easy way to keep track of resting heart rate every day which could help detect overtraining. (Doesn't seem like it can do HRV so can't get more advanced data (Firstbeat Sport can do that, but to me their product is way to expencive)) They just finished their indegogo campaign so no one has really used i yet to know if its any good or not (link to indiegogo.com) Seems like many of the Zeo people are helping the Beddit team. I contributed to the indegogo campaign so hope it is a good product.

      Then there is Angel (link to igg.me) which is currently up on Indegogo which while is is an activity tracker, it also records heart rate and can record r-r intervals to do HRV annalysis. This is an open hardware platform which is great as they are trying to make it easy for 3rd party developers to use the data coming off their wrist strap with the negative side being that the app that ships with the device may not be as full featured (they are open sourcing the app so others can then create better apps) I have a feeling Angel has great potential and at worst even if it doesn't have any good apps written for it will still be a good BLE wrist based heart rate strap (I contributed to this one too)

    I've used several Fitbit devices now and have some thoughts that might be useful.

    The Flex which Ray didn't find too useful is nice if you meet two criteria. First, you don't like devices like the One and Zip as you are too worried you will lose them in the wash, etc. so prefer the wrist band. Of course, people who prefer a wrist device now have the Force to choose from as well.

    Second, you always have an iPhone or similar device that can run the Fitbit app. In the middle of a day, doing the tab to see three out of five lights blink lets you know you are 3/5ths of the way to your goal (you've between 6,000 and 8,000 steps if you use the default 10,000 steps a day) and for anything else you simply launch the app. One can also get additional colored bands and swap the Flex device between them to color-coordinate, which you cannot do with the new Force. If you care about the Sleep tracking feature, its easy to use with the Flex, whereas the One requires you to put it in a separate sleeve.

    Moving to the One, if you don't care about sleep or stairs, the Zip is almost certainly a better, cheaper device. The stairs feature can be useful for some people. I had a job where I worked in an office on the fourth floor of a building and would take elevator half the time and stairs the other half of the time. With the One, I'd be encouraged to take the stairs a lot more, and those little bits add up. It's the same principle all the Fitbit devices proclaim that if you are aware of your numbers you want to improve them. You'll tell yourself: "Only 4000 steps today, I'll park at the far end of the parking lot to get groceries, or actually, I only need a few items and it is nice out, I can walk to the store instead." However, if you live and work in an area without many stairs to encourage you, then that's a feature you don't need.

    Fitbit could publish a flow chart to pick the right device. Do you want clip on or wrist? (I like using the One and Zip in my coin pocket in my jeans.) Do you care about either sleep or stairs data? If you choose wrist and no, then one final question -- do you have a mobile device to have the app handy?

    Now the Aria. I like it quite a bit. It is easy to use and for weight it has been accurate and consistent for me compared to my weighing elsewhere like the gym. For the body fat%, I have no idea if it is accurate but it is fairly consistent with an occasional spike up or down. I find it useful as I see both my weight and body fat dropping over the last six months as I have improved my fitness. From what I've seen of the Withings scale it seems about the same overall, so choices between the two would be due to aesthetics of one device over another, or more importantly, the various things they can connect with.

    OK, so I have to know. What is that Garmin watch in one of the last pictures dealing with the calories. I haven't seen that one and it doesn't look like the 220/620. Is it a gps watch? If not, that's probably why I don't recognize it.

    And if like me you upgraded your Galaxy S4 from Android 4.2 to Android 4.3, you may find a annoying bug that prevents your fitbit device to connect to your smartphone by bluetooth.

    I bought the fitbit aria today. Body fat measurements have been... inconsistent.

    Out of the box, it put me at 33-34% body fat. That's not right.

    I switched to "lean" mode in the settings, and that dropped me to 18%. That might be right. I don't know.

    A few hours later, I weighed in again. I'm apparently now 11%. That... is probably low?

    I don't necessarily expect perfect accuracy, but a little precision would be nice. Oh, it also hasn't been updating to Endomondo despite my having enabled it...

    I read your review and purchased a Fitbit Zip. I track all my workouts with my Garmin 310XT but want to use this device for all the other hours in the day when I am at work or doing weekend activities not exercise related.

    I notice from your review that you were able to add sleep logs manually which seems to be my only option yet nowhere in the literature or online have I been able to find out how to do this. The website and iOS app do not provide this option. Were you able to do this as you have multiple devices set up for the dashboard? If not I am unable to figure out how you did it.

    Thanks for such a great site. I appreciate all your hard work.

    My favorite part of my FitBit is playing the "guess the flights of stairs" that I've done. On a typical day it is pretty accurate. But it is most entertaining to wear it hiking or site seeing. One mountain bike ride was mysteriously 56 flights of stairs. Hiking in Dupont State Forrest was 80+. Going up the Duomo in Florence was 35.

    In general I apprecitate this a good way to measure my relative activity day to day. But don't take it too seriously.

    Uploading data to the website works correctly for first zync, but if I zync again then it seems to drop my steps rather than increasing them. I then only zyncd once a day, but the following day looking back on the previous day it had dropped steps from what was initially uploaded. Does anyone have this issue?

      Yes I have the same problem when I sync sometimes it updates correctly then when I sync again it will drop my steps and miles in half but active minutes and calorie burned stays the same. I can't figure it out.

  24. I recently bought the zip Fitbit and the tracker fell out of it's case when I bent over (or something similar) is all I can deduce. I'm very disappointed in the design (i.e. how the zip tracker doesn't fastened more tightly within its case), as I trusted it would stand up to daily activities. A hard lesson to learn as I am out approx. $60.00 USD (within lesson than 1 week), and am hesitant to purchase another Fitbit due to the design flaw.

    The Fitbit zip has a problem with battery life. I have owned two and they both die intermittently because the battery disconnects. The batteries are good it is the device that is faulty. Fitbit knows it and does nothing to back their product. DO NOT BUY!!!!!!

    So I accidently discovered how to get better accuracy with my Zip. I lost the rubber carrier and ended up tossing it into my plastic Strava pouch I put in the back pocket of my jersey. Lo and behold, the last two rides the darn thing is remarkably close on steps compared to my pedal strokes as reported by Garmin. Previously I was clipping it to my sock, but it could be off by a 1,000 steps on a ~5,000 pedal stroke ride.

      I compared accuracy of my Zip inside it's holder to my other GCC three axis pedometer and it was within 2% difference. There's always going to be some difference in counting of various non-step movements, counting walking should be almost perfect, I think bigger differences are caused by how it's worn

      Unfortunately, none of the activity trackers do a good job at giving useful metrics in a pool. They'll usually count some sort of activity (if waterproof), which some might find acceptable. But ultimately it's a complete wild guess.

    I have had the zip for about 3 weeks now. I love it. It syncs with my lose it app, and with run keeper app, so I don't have to log things 3 times. I walk 5 miles a day M-F, and 8 on Saturday. I also do a little cardio. Today though, I noticed it had the data from my morning, walk- I saw the steps and the mileage. Later in the day, after about 5 hours when I looked at it, it was down to only 1.4 miles walked. All of that other data disappeared. Its still working, and has continued to log steps. Should I change the battery? I logged the walk manually on my dashboard on the desktop.

    I have had my Fitbit Flex for about 5 days now. I noticed today that yesterday's step count (which had been at >22,000) dropped to around 21,000... Not a big deal, but I would like to know why... I have 22,000 steps set as my daily goal, so not hitting my goals bugs me, but hitting it and then losing "credit" for it REALLY bothers me... Looks like a silly software problem.

    Another issue that I have is that the sensitivity is too low - I get an accurate step count when on the elliptical, but when I walk (unless I WILDLY swing my arms) the flex captures around 60% of actual steps). Some have mentioned that they want to use this device to measure non-workout activity, or the other 23 hours of the day... But if this is what is most inaccurate I will have to say that it falls short... Seems like a firmware setting - someone at Fitbit must have decided to reduce sensitivity to avoid spuriously measuring small motion as steps, but went too far. PRODUCT FEATURE IDEA: User settable sensitivity,

    I have to say that I am not impressed SO FAR. But, considering I am a refugee from the Jawbone Up24, having replaced that buggy hardware 7 times - thank goodness for extended warranties, and the foresight to buy it - I am willing to give the Flex a little more time to grow on me...

      I'm not quite sure why it did that, but I will say I'm impressed - 22,000+ steps for 5 days in a row is pretty impressive. That's a heck of a lot of walking (or even running).

    I've been doing some research into the countless options of pedometers out there now on the market. While it is nice there are so many to choose from, it is also a problem: they are expensive, and very hight tech. Synching with my smartphone and computer? Software upgrades? Sleep measurement!? It all seems like overkill, almost Orwellian in fact: to wear the Fitbit One thing continuously day and night? Reminds me of the ankle tracking devices criminals on parole wear so the probation police can monitor their movements. The problem with hi-tech products like the Fitbit line is this: the more hi-tech, multi-featured, and complicated the product the more technical problems invariably come your way. You will spend more and more time dinking around with the user interface, synching a mass of data.....what I'm saying is this approach is overkill: I just want to track daily steps taken, maybe a rough idea of calorie burn. Anything more is trying to suck me into their whole schtick of over-featured crap. My life is already too complicated. I feel like a part time software engineer with all this crap on my computer for example. Everything is getting to over-featured. We are further and further away from what Chinese philospher Lao Tzu once said: keep it simple for more peace of mind. å

    For 8 years I've relied on the pedometer in my Sony Ericsson w580i phone but I many not be able to find a battery for that soon. It was the most remarkably accurate step counter I've ever found.
    The Zip looks like a good replacement candidate, even if it won't sync with my Blackberry Z10.
    In your review of the Zip I don't see any mention of how to calibrate it in kilometers and have the display report the distance travelled in kilometers.
    And finally, it would be essential to have an OFF button so it doesn't count steps as I'm riding my motorcycle home from work and vibrating enough to register thousands of steps I haven't taken. Is there a simple on/off or run/pause switch on the Zip?

      No, it won't really work well there since there's no actual movement. The FitBit Zip was designed for tracking walking, and that's pretty much about it. Sorry!
