Fitbit Flex vs. Jawbone UP: A Comparative Review

Fitbit Flex vs. Jawbone UP: A Comparative Review fitbit flex jawbone up reviewIn today’s world, nothing escapes the fact that we are moving in a direction where quantifying and recording stuff obsessively is sort of the norm. We use Foursquare to check into places, we annoyingly take photos of our meals with Instagram, and we share our thoughts on Twitter. So would it be much of a surprise if we also like to track the number of steps they take, or how much we sleep?


The Fitbit Flex and Jawbone UP are two very popular products in the wearable activity tracker category. These are devices which you wear on your wrist, and they’ll record how active you were, among other things. Fitbit is no stranger to activity trackers — they make lovely products like the Fitbit One which we reviewed Fitbit vs. Garmin: Fitness Watches Compared In the market for a new fitness tracker? Then you've probably compared Fitbit vs. Garmin. We're here to help you decide which brand is best for you. Read More a couple of months ago; so they know what they’re doing. Jawbone, on the other hand, are pretty green in this area — sure, they make wonderful Bluetooth devices like Jambox, but activity trackers is a whole different ballgame.

So the question is: which one should you buy? Today, we’ll put the Fitbit Flex and the Jawbone UP against each other, and decide whether it’s the newcomer or veteran who takes home the gold.

We’ll also be offering both devices, so enjoy the review then remember to join the contest.

Introducing the Fitbit Flex and Jawbone UP

As I mentioned earlier, these devices are essentially activity trackers which you can wear on your wrist, as opposed to classical activity trackers that clip onto clothing e.g. jeans, pants, etc. The idea is to never take them off — so you wear them in the shower, and even in bed. In addition to measuring the number of steps you take, both devices are also able to record your sleep — the quality as well as duration. Finally, and this is just an added extra — they are also silent alarms, waking you up through gentle vibrations (if you wear them to sleep, of course). Both devices must be synced with a compatible smartphone in order to retrieve the collected data. If it sounds confusing, don’t worry, I’ll elaborate as we progress through the review.

The Jawbone UP retails for $129.95 and comes 3 sizes: small, medium and large. It’s also available in 8 attractive colours. Selecting the right size isn’t easy — the UP either fits you or it doesn’t. If your wrist is between two sizes, like mine is, Jawbone recommends going with the larger of the two, and you’ll have to live with a slightly oversized UP band for the foreseeable future. Mind you, the coloured bands aren’t interchangeable, so once you pick a colour, you’re stuck with it.

The $99 Fitbit Flex is more accommodating. While the Flex is available in only two colour options (black or slate), it is shipped with the tracker and two adjustable and interchangeable bands (a small and a large). Additionally, Fitbit offers a $30 accessories pack which expands your band collection by three more colours: Teal, Tangerine and Navy.

Surprise, surprise. These aren’t the only two wearable activity trackers on the market. Of course, there’s the infamous Nike+ Fuelband ($149). However, it’s activity-centric — in other words, the Fuelband is designed to focus on how active you are, and how many calories you burn. Moreover, its chunky design doesn’t quite bode well with the ladies.

Then there’s the $200 Basis B1, which looks more like a really retro watch. The only thing the Basis B1 has going for it is an integrated heart rate monitor. Sadly, Basis doesn’t provide a mobile platform to sync with, so you won’t know what to do with the collected data until you get home and connect it to your PC. Also, you wouldn’t want to be seen as though you’re wearing two watches, would you? No, that’d look weird.

Fitbit Flex vs. Jawbone UP: A Comparative Review basis



Coming from a manufacturer obsessed with design, the Jawbone UP is quite fashionable. It’s also very minimal. The TPU rubber wristband houses the clever gadgetry which records your activity, as well as two hidden LEDs to indicate the mode that the UP is in. As you can tell by now, the Jawbone UP doesn’t have a screen so it’s unable to display your progress until you sync it with a compatible mobile device. Putting it on your wrist the first few times can be tricky but you’ll notice that the UP is rather sturdy and won’t break quite that easily.

jawbone up review

The band is roughly the same thickness (7mm) throughout its entire length, and I’d say that it’s bordering on bulky, especially for ladies with slimmer wrists. On one end, you’ll notice a small button — pressing it triggers the mode indicator. A long-press activates or deactivates sleep mode.


On the other, removing the Jawbone-labeled cap reveals a 3.5 mm jack which is used to charge and sync the Jawbone UP. The UP is also water-resistant, so you can wear it in the shower but you shouldn’t take it swimming.

jawbone up review

As you can tell, the design of the Flex is slightly more basic. Unlike the Jawbone UP, perhaps the Flex was made to blend in rather than stand out. The Fitbit Flex is actually made up of two components: the tracker and the silicone rubber wristband with a small transparent window. Even though Flex comes with small and large bands, both bands are adjustable; allowing you to further fine-tune the Flex to fit comfortably on your wrist.

fitbit flex vs jawbone up

The tracker slots into a compartment on the thicker side of the band, and remains there until it needs to be charged. Other than that, the silicone band is pretty unremarkable.

fitbit flex vs jawbone up

The Flex doesn’t have any physical buttons, so to compensate, it recognises two series of taps which either invoke the progress meter or sleep mode. The tracker has 5 LEDs built-in, seen through the band’s transparent window, and they light up in very exciting K.I.T.T-style flashes. Each flashing LED represents 20% of the daily activity goal (which is configurable). So say, the goal is set at 10,000 steps, one flashing LED would mean that you’re still within 20% of that goal i.e. less than 2,000 steps.

See it in action:

The Fitbit Flex is also water-resistant — up to 10 meters. Unlike the Jawbone UP, the Flex can be worn while swimming.

Setting up and connectivity

Setting up the Jawbone UP is rather easy. Start by downloading the free mobile app for iOS [No Longer Available] or Android and plug the UP’s 3.5 mm jack into the phone. The app will guide you through the setup process, then a tutorial on how invoke sleep mode, nap mode, and the stopwatch.

fitbit flex vs jawbone up

Here’s the thing: the Jawbone UP isn’t fitted with Bluetooth despite the fact that it was designed and manufactured by a reputable company specialising in Bluetooth technology. In order to sync, the UP needs to be physically connected to a smartphone via the 3.5 mm jack. This may be a turnoff for some — I should know, I’m one of them. Not only does the UP lack a progress display, having to physically sync it every day can be inconvenient and demotivating.

Next, Jawbone doesn’t offer an online dashboard to view your data, so the mobile app is all you get. On the bright side, the mobile app is nothing short of fantastic — I’ll tell you why in a minute.

fitbit flex vs jawbone up review

As for the Fitbit Flex, getting started is slightly more difficult, and requires access to a PC in order to download the desktop client. However, after getting through that boring bit, the Flex is able to pair with a compatible iOS or Android smartphone via Bluetooth. Not only that, as long as they’re both in range, the Flex will occasionally sync in the background, and provide you with real-time progress when the mobile app is open. Personally, that was one of the things I was looking forward to most about the Fitbit Flex; after having to endure with 2 months of retrospective reporting from the Jawbone UP, being able to view my progress in real-time was a breath of fresh air.

Wearing the Fitbit Flex vs. Jawbone UP

In order to prepare for this review, I’ve been wearing the Jawbone UP for the past 2 months, and I’m glad to say that I hardly ever notice it now. Although at the start, it did get in the way slightly. For a person who’s not used to wearing decorative bracelets, having the Jawbone UP on my wrist felt awkward, especially when typing, and required some adjustments. Due to its thick-ish size, I also had difficulty putting shirts on and pulling jumpers over the UP; or taking clothes off with the UP in the way, for that matter.

fitbit flex vs jawbone up review

Jawbone recommends wearing the UP on your non-dominant hand for more accurate tracking and that’s a fair point since vigorous dominant hand gestures does affect the UP’s accelerometer and exaggerates the numbers it reports. I’ve tested the UP on both my dominant and non-dominant hands — and the numbers from the dominant hand were often inflated, reporting more than two times the number of steps I took. However, you’ll find that it isn’t always possible to wear both the Jawbone UP and a watch on the same non-dominant wrist.

fitbit flex vs jawbone up review

In comparison, the Flex’s band is simpler: it’s wider and slightly less tall where the tracker is housed (compared to the Jawbone UP), but shifts to a much lower profile as it goes around the wrist — very much akin to wearing a watch. So it’s less likely to get in the way of putting on clothes, typing on a keyboard, or using a mouse. It also fits better since Fitbit provides two bands (small and large) to choose from, and both bands are adjustable via a clasp mechanism.

fitbit flex jawbone up comparison review

Between the Fitbit Flex and Jawbone UP, the Flex is a hair lighter and has a lower profile overall, making it easier to navigate through daily life without being much of a bother — so it wins my vote plainly on comfort. It’s also more comfortable to wear in bed, if you’re curious to know. The UP is fitted with a battery which lasts for 10 days, and takes only a couple of hours to recharge. The Flex doesn’t do as well, with only a 5-day battery life but it does sync wirelessly so that explains the disparity.

fitbit flex jawbone up comparison review

However, the Fitbit Flex does have one fatal design flaw.

The fatal flaw

Well, depending on how you look at it, it might not be fatal but it is quite annoying. While the Jawbone UP is one solid construction, the Fitbit Flex consists of the silicone rubber wristband, and a tracker which slips into it. The design would allow water to seep into the compartment while showering or even during hand-washing, and it never dries out as long as the tracker remains tucked in. As a result, you’ll notice water droplets through the transparent window.

fitbit flex vs jawbone up comparison

This becomes more evident when the tracker is removed for charging — the tracker itself isn’t affected with the water but the humidity built up in the compartment over days encourages bacterial growth.

fitbit flex vs jawbone up comparison

Tracking and reporting

In terms of activity tracking, both devices are equally accurate. The Jawbone UP is powered by motion recognition technology supplied by MotionX and is slightly more ambitious than the MEMS 3-axis accelerometer used in the Fitbit Flex. It’s not easy to tell what constitutes a “step” in the eyes of the Jawbone UP purely due to the fact that it isn’t able to report in real-time. However, with the Flex, it’s quite easy because it syncs with the mobile app continuously via Bluetooth. I was surprised to learn that the Fitbit Flex is able to recognise my steps even if my wrist isn’t swinging. For example, if I’m carrying something in my non-dominant hands while walking, it would still register my paces. Pretty impressive. I did try walking backwards — that did not register.

The data from both devices need to be offloaded to a mobile app in order to be interpreted and presented.

Having to compensate for the lack of an online dashboard, Jawbone UP’s mobile app is beautifully designed and very insightful. It analyses and then lays out the data in a way that’s easily digestible: daily progress, number of steps taken and distance travelled, active duration, idle duration, and calories burnt. Since the UP also tracks your sleep pattern, and if you remember to enable sleep mode before going to bed, you’ll be rewarded with some really interesting reports on your nocturnal activity: the duration of light vs. deep sleep, the number of times you were awaken, and how long it took you to fall asleep. Personally, I’m a very poor sleeper — and with the reports from the Jawbone UP and Fitbit Flex, I now realise that I’m awaken from sleep between 4-14 times a night. It helps to obtain quantifiable data about my sleep quality because I’d be able to try different techniques to improve my slumber and determine what works.

fitbit flex jawbone up review

Using the UP’s mobile app is very satisfying since it provides minute-by-minute activity/sleep graphs, so I’m able to easily visualise what time of the day I’m most active. The downside: all of this lovely data is retrospective. The UP needs to be manually plugged into a smartphone in order to sync, and isn’t able to display your daily progress on the band. So you won’t know if you’ve hit your daily goal until you sync it. Despite that, the Jawbone app is still fantastic to use because there’s so much you can learn from it. It manages to display your data in the most relevant forms. Take Trends, for example — the app basically plots your entire life as a bar graph: how you’ve slept, how active you’ve been. And it motivates you as well, by encouraging you to beat your achievements from the week before.

fitbit flex jawbone up review

On the other hand, the Fitbit Flex syncs via Bluetooth with a compatible smartphone and reports your progress in real-time, without having to remove it from your wrist, which is great! Unfortunately, Fitbit’s mobile app is quite drab — at least the iOS version is. Sure, it’ll display the number of steps taken, distance travelled and calories burnt; but for minute-by-minute activity reports, you’ll need to head to the online dashboard. And that’s where the Fitbit mobile app falls short. Aside from the most basic numbers, it doesn’t offer anything else — no analysis, no interpretation; just raw numbers.

fitbit flex jawbone up review

One of the many things that you’ll have to train yourself to do while wearing an activity tracker is to enable sleep mode at night. Otherwise, neither the Fitbit Flex nor the Jawbone UP will record your sleep quality. Sure, you’d be able to manually input the number of hours you snoozed, but it’s not the same. One of the advantages of the UP is that it automatically comes out of sleep mode whenever it senses activity for a prolonged period of time. Unfortunately, the Flex doesn’t — if you forget to disable sleep mode, it won’t track your steps throughout the day.

Other features

Both the Fitbit Flex and Jawbone UP have something called a silent alarm which vibrates instead of beep, so your partner isn’t awaken if you decide to go for a jog at six in the morning. Even though they’re both “silent”, the Jawbone UP vibrates as long pulses and is moderately vigorous, not to mention quite audible as well. The silent alarm on the Flex, on the other hand, vibrates as four short bursts then one long pulse followed by three short bursts; and is comparatively more subtle than the UP but equally as effective. However, the Jawbone UP does claim that their alarms are “smarter” in the sense that it recognises when you’re in a light sleep cycle then fires the alarm within a 10-minute window of the set time. Apparently, you’ll wake up fresher by using a smart alarm but I have yet to experience this “fresh feeling” they’re referring to. The Flex simply vibrates when it’s time to wake up.

Although I’m not a big fan of the following feature on the Jawbone UP, I feel that it’s my responsibility to inform you about it. The UP has a neat ability to detect idleness, and after a certain period of time, the band will vibrate to remind you to take a walk. While this is an awesome feature for folks with sedentary lifestyles and need a little reminder to stay active; I work at a standing desk, which means I’m on my feet, and not sitting on my behind all day. And I’m mostly typing away at my desk but the UP doesn’t recognise all of that, and the constant buzzing to remind me to walk around can hinder my productivity quite a bit. But I’ll admit that the Jawbone UP’s idle alert can be a useful feature to some, plus it’s something that the Fitbit Flex does not offer.

Finally, between the two devices, only the Jawbone UP supports IFTTT integration. IFTTT (IF This Then That) is an online service which automatically performs certain actions based on preset triggers. For example, it can automatically create new Tumbler posts from saved Pocket favourites Supercharge Your Pocket Experience With These IFTTT Recipes Between the two of them, Pocket and IFTTT are excellent services that do their part in making their users more productive. Pocket gives users a one-stop shop to access all of the content - articles,... Read More or notify you by SMS whenever you have new emails. Using IFTTT, you’d be able to automatically email your spouse a warning if you had less than 7 hours of sleep, or automatically turn on the coffee machine if you had less than 5 hours. I’m slightly disappointed that Fitbit hasn’t announced IFTTT support, even though most of their devices like the Aria smart scales Fitbit Aria Wi-Fi Smart Scale Review and Giveaway Whether your goal is to maintain a healthy weight or lose those extra pounds, keeping track of your weight changes is an essential part of the process. Any obstacle to doing so will eventually halt... Read More (and now the Fitbit Flex) are able to go online on their own. I reckon they’re doing their consumers a huge disservice by neglecting to integrate with IFTTT.

Fitbit Flex vs. Jawbone UP: which should you buy?

The Jawbone UP is trendy and its mobile app is outstanding, but its fixed-sized wristband and lack of real-time synchronisation leave a lot to be desired. The Fitbit Flex is utilitarian in both form and function, but its mobile app for iOS is abysmal and Fitbit’s decision to neglect users of IFTTT integration is beyond my comprehension. Ideally, I’m after the complete package: a great-looking yet adjustable wristband, a functional mobile app, wireless syncing capabilities, and IFTTT integration.

fitbit flex vs jawbone up comparison review

Before choosing, you really need to figure out your needs. Do you require real-time tracking? If you do, then the Fitbit Flex is for you. If you’re looking for activity tracker that doesn’t require much attention, then go with the Jawbone UP. Personally, I’m undecided. Both devices are flawed in some way, but brilliant in others. And even after writing this 3,000-word review, I can’t figure out which one I would buy.

MakeUseOf recommends: Do not buy either. Both devices are terrible.

Update: After about six continuous weeks of wearing the Fitbit Flex, the silicone rubber wristband started to fall apart. There’s now a large tear just below the translucent window on the inner surface of the band. Couple the low build quality of the band with the grossness I mentioned earlier, I cannot recommend the Flex. The Jawbone UP also stopped working, and needed to be replaced. Both devices are significantly flawed. Wait for the Withings Pulse Activity Tracker.

    Jawbone up for me. For two reasons
    1: I love the App Interface, and I don't mind having to plug it in. If you time it with your meals it makes it easier to remember.

    2.)The interface is much easier to use. I literally bough this in an airport last week, Synced it to my phone in minutes, and was able to capture my steps from Philly to Cincinnati to Milwaukee.

    Get one of them! I had no idea why I was so tired in the morning, and the sleep monitoring showed me why.

    I would strongly recommend against the UP band because I had two malfunction (battery issue) within a week of each other. Luckily, it was a gift from a client (fitness professional for over 10 years) so I didn't waste any money. After reading different forums online, including Jawbone's, it seems like this is an on going issue. The first generation had to be recalled so one would figure that they would get it right the second time. I would suggest tracking meals and calories with the numerous free online resources.

    On a personal note, what man would want to wear a cheesy looking "bracelet" 24 hours. All of my friends (male and female) would ask, "Since when do you wear a bracelet?" I tried it simply because it was gift. As someone who eats and sleeps fitness, I would never recommend this product.

    Too late for the contest but I had to leave a comment. I've owned a Jawbone UP since Christmas and already replaced it once and planning to do it again. How can a device created for active people be so flimsy? The first time, it stopped working. This time, the little knob that changes modes has fallen off. I'm not rock climbin - just a normal active exerciser. I was searching for alternatives!

    I purchased a jawbone up on April 2, 2013 and it stopped working on June 15,2013. My cousin also had issue with the device and had it replace 3 times so I decided to exchange it for the fitbit flex.

    I find the flex to be more comfortable and I prefer using the desktop to do analysis vs using the small screen of my iPhone. The only huge gap is the lack of IFTTT integration. I really enjoyed posting to Facebook when I walked over 10000 steps and adding my sleep info to my calendar.

    When I purchased the jawbone up there wasn't any integration to many apps, but it came quickly and I am hoping the same for the fitbit flex.

    FitBit flex: for same price as the Jawbone UP you get interchangeable colors to match mood/outfit; can go swimming with it; low profile & adjustable wristband; Bluetooth syncing; android & iOs compatibility. Yet, water collects in band & several say app isn't as desirable as Jawbone UP.

    Jawbone UP: bracelet is easier to put on but can get in the way- isn't adjustable or interchangeable; can't go swimming with it; no Bluetooth syncing-must be connected; app looks better & gives more detailed information; has "smart" wake-up. Some say not completely on Android yet. Due to no Bluetooth, the battery lasts longer.

    I think it boils down to Do I want better style on the wrist or better style on the linking app?

    As an avid gym goer and dancer, the fitbit seems to have better functionality, it seems to be more user friendly, and gives better details to a person's health goals. I need something that will keep up w/ my hectic lifestyle and gym time. The sleep tracker seems to be an awesome helpful tool and I'm so axious to get my hands on one to try it out. Very excited about this giveaway and I sure hope I'm in the running to be selected to receive one. Thank you.

    I think people too easily forget the advantage of bluetooth syncing rather than taking the bracelet off for syncing. You can keep it on for a shower but need to take it off for syncing? Crazy. Also the visual indicator on the band to show how close you are to your goal helps to achieve what you want - unless what you want is a fashion statement, which seems to be the case in the comments. Flex for me, although I have been undecided for days.

    The Jawbone UP, because of the battery life, more than raw numbers, the sleep function sounds better than Fitbits.

  127. Riika
    June 4, 2013 at 3:10 am

    I can't decide! I have been googling reviews and that is how I got here. The sleep tracking is one of the main reasons I want this device and I am not sure which one is better for that. One review I read said the Fitbit was better but I like a lot of the features of Up more. Ugh so hard!

    I have been trying to decide between the two of these for weeks now. My gut says Flex, but the UI for the UP app looks way better. I am not sure if the IFTTT would much come into play in my life, but it might be fun to mess around with.

    I would be happy to win either, just so I can have my mind made up for me.

    Such a difficult choice! I started thinking I wanted the Fitbit then I saw the Up and started leaning towards that. However I kept researching looking at reviews and all sorts and as I felt I had decided on the Up...the Fitbit was back in the mix! So I kept researching and eventually went for the Fitbit. Its wireless sync, progress display and more waterproof(nes) were sort of what swayed it for me. Also, it's App may not look so nice (which was why I was thinking of going for the Up) but it does all the same things and has many supporting Apps too. Hope this helps anyone :)

    It's a tough choice after reading the review but I would have to go with the Fitbit mainly because of the wireless sync. It just seems inconvenient to have to take off the device to sync when everything has bluetooth capabilities now (the speed of its sync does make up for that to some extent). A few things points towards the UP because the application seem more appealing to me as well. I would love to win either one! I have been transitioning towards a more healthy lifestyle and this would truly be a great gift to win [I have yet to win!]. I would love to see how this will support me in my physical goal.

    Like Jackson, I am still undecided, I'm leaning more into the FitBit Flex due to negative reviews about the Jawbone Up dying after few months of use, but the 6-8 weeks backorder of the Flex sucks. Also UP's design and app UI is better than the Flex. Oh dear why...

    Jackson, do you really these? There is no way in God's green earth I would! Color me suspicious, paranoid, whatever but if my phone and/or computer can keep track of me, what else can? There have been so many ways that hackers and worse have figured out how to defeat each and every privacy tool out there not to mention the government. Just when you think that finally we have some real protection against the invasion of our privacy, someone comes up with a way to invade it. If you seriously think that the government is NOT tracking us, I can tell you that is false. A family member used to work for the company that was, in part, designing and implementing "Carnivore". (I wonder if this comment will even show up? - lol) Also, if you and/or your readers have been paying attention, SB744 (the immigration bill) stipulates that we all have RFID trackers. No thanks. It is bad enough my phone shows where I am all the time. :(

  484. Daniel Lamblin
    May 26, 2013 at 8:20 pm

    I bought a Jawbone UP for Christmas 2012, not quite understanding that A) it wasn't a bluetooth device, B) it only worked on mobile devices (no desktop app or sign up or support) and C) it (then) only worked with an iOS mobile device. After 2 months of waiting for the "coming soon" android app, I returned it, because I couldn't even initialize it and start logging steps and sleep. It says it can remember 90 days of steps and sleep between syncs as long as you keep charging it each 9-10 days. That would have still fallen short of the android app release in April, but had the desktop USB dongle supported at least signing up and starting to record activity, I might not have returned it.

    Given this, and supports' in-ability to even guess at an android date (could have been 2014) I will not be trying this product again. Particularly I do prefer the realtime and desktop support of the Fitbit Flex, and I hear that there is an ecosystem of third party apps and data-sharing for the fitbit, even if it doesn't include IFTTT.

  485. Jeanette
    May 26, 2013 at 7:11 pm

    I like the ability to sync up wirelessly, although I also like the added metrics - hopefully either fitbit or jawbone will fix these features so they do both.

    Jawbone UP! I like pretty colorful graphs and love the insightful analytics it provides. One thing regarding the lack of "real time" reporting. After a few weeks/months, how many people are still going to be checking throughout the day for instant feedback? I think the historical trending information is going to be much for valuable and useful to people by then, and less so about "where am I this hour?" It's like anything else these days. Once the novelty wears off, the frequency of on-demand feedback will lessen.

    • Jackson Chung

    Friends of mine have been commenting favorably on this article Jackson. Fantastic review!

    I read that Bluetooth 4.0 is available in the latest fitness bracelets. I know that most phones don't even have BT 4.0, so it's kinda difficult to test, but the battery life is supposed to be improved on the new standard.

    Could it be that on BT 4, the 5 and 10 day batteries might be greater?

    • Jackson Chung
      May 28, 2013 at 5:58 am

      Thanks, Kannon!

      The 5-day battery life is true for Bluetooth 4.0 phones. I tested it with an iPhone 5. Hope that helps.

  541. rhondacallow

    They both look like great products. I would probably choose the Jawbone UP, simply because it's blue ... and because I don't need real-time tracking. :)

    • Jackson Chung
      May 28, 2013 at 5:59 am

      It comes in other colours as well :) But like you, I chose blue.

    I'd go with the Jawbone UP. It seems like the app is better designed and the IFTTT integration definitely puts it ahead of the Fitbit Flex.

  553. Joan
    May 24, 2013 at 3:42 pm

    Great side-by-side comparison. I'm still undecided. I lean towards the Flex. I love that it has a better fitting band, and can handle water. As a Fitbit One user, I already am familiar with the tools available online and with the app. On the other hand, I place a high value on the idle alert, and integrating with IFTTT.

  554. Peter Whittle

    May 24, 2013 at 2:17 pm

    While both have their pros and cons, the fitbit flex would be my preference. I prefer a few of its features and a bonus is it would allow me to join the friendly fitbit competition currently happening between some of my workout buddies

    • Jackson Chung

    Jawbone UP. I'm not interested in real time stats, but in an overal detailed history of everything.

    And I don't want to go to the online dashboard to check things out.

    And bluetooth takes to much battery, so it's never on, so the real time bluetooth sunc is useless to me.

  567. Pablo P

    I like the Jawbone Up, specially because of the design and the app, but I miss a web version. I don't see the lack of Bluetooth as a problem, although I like the real time sync.

    Jackson, I would like to know about your experience with the Jawbone. I've read plenty of comments in their forums saying that their wristband was broken after a couple of months. Is it really that fragile?

    • Jackson Chung
      May 24, 2013 at 12:13 pm

      That was probably their first iteration of the band. The one I reviewed works really well. Like I said, I shower with it on, wear it to sleep, running, basically it's on my person 24/7. It hasn't lost any of its elasticity and still manages to hold its shape rather well.

  568. Emma
    May 24, 2013 at 9:29 am

    Both sound excellent, but I'm inclined to go for the Fitbit Flex. I'm calorie counting and the real-time tracking would be far more useful to me, over the day.

    Thanks for the review and opportunity to win!

    • Jackson Chung

    An informative review but, for easy comparison, it would be useful to have a table at the end showing the features each device has or lacks.

    One query: is the Jawbone UP really about 50mm thick? Surely that can't be right?

    • Jackson Chung
      May 24, 2013 at 12:18 pm

      Whoops, no I meant that from top to botton, it's roughly 50mm. The band itself is 7mm thick. Bear in mind that I reviewed the medium one.

The ones that have the fitbit are always complaining about the construction and how hard it is to put on. The one friend that has both the Up and nike wears both at the same time. Likes the up better but likes the read out of the nike. I'm eagerly waiting on the amiigo.

  639. Rob
    May 23, 2013 at 6:11 pm

    Tough call...I think the Flex, since it has an easier way to sync. I think the bigger question is whether these devices actually have an impact on our lives. The reviewer doesn't say whether the feedback was useful or not.

    • Jackson Chung
      May 24, 2013 at 12:27 pm

      Actually, I did. I mentioned that it's nice to have quantifiable data about the quality of my sleep. Plus these devices are highly sought out by people who are trying to stay active anyway. You can't give it to someone who doesn't know what to do with it, and expect the device to have a positive impact. It's a tool used to help those wanting to achieve a goal.

  640. Seth
    May 23, 2013 at 6:08 pm

    Great review. I was just meaning to get one for my better half. I might have to stop myself from getting one for myself too. Hard to decide which one though. But I think the battery life of UP is a winner!

      The UP is also easier to maintain. It can store up to 9 months of data until you sync it. Plus when it's running low on battery, it'll remind you on your phone.

    I think the Jawbone UP would be the right choice, even if you do have to upload things daily for information. It forces the routine of wear - walk - upload. I think that structure is a good reminder to keep moving.

    Based on the review, I am having a hard time deciding, as well. The style and construction of the Jawbone, as well as the mobile app, though see me leaning towards it. I hate that it doesn't have Bluetooth and auto-synching, though. Give me that and I would be all in.

    I have the FitBit One and love it. I was contemplating getting the Flex until I read a review that talked about how it was "off" in it's step counting & such (sorry, can't find the review now). I'm curious as to how the three would compare. A Jawbone Up and Fitbit Flex on the same arm and a Fitbit One attached to my pocket. I realize nothing is going to be 100% accurate all the time, but seeing how each one reports activity would be an interesting comparison. I carry a Virgin Health Miles pedometer from work and it's usually pretty close to what the Fitbit One reports. Overall, I'd have to go with the Fitbit Flex over the Jawbone, simply from my experience with the One and the fact that it has BT sync so I never have to remember to plug it in. Having the app on my phone tell me that the battery is low is pretty darn handy too.

  699. Jesse Shinn
    May 23, 2013 at 3:13 pm

    You know, I just joined and I'd have to say programming "Meal", "Workout" and "Loop" times along with the idle activity moniter to get me using my "Gold's Gym" or my "Shake Weight" throughout the day would be major selling points for me.... So I'd have to go with the "JawBone" no question about it!!!

  700. Deed Black

    Considering it's bluetooth connectivity, tiny LED screen, online dashboard and integration with MyFitnessPal, I'd go with the Fitbit Flex.

  704. Mike C

    I can't decide either. Probably the Jawbone because it has fewer problems with water. But I like the FitBit's ability for real-time syncing...

    I think I would pick the jawbone up! I like the extra feature of food and drink logging, and it seems interesting that it shows you connections between your moods and activities. My initial choice was the fitbit flex but upon further investigation it seems that the jawbone up does the same and a little more.

    • Jackson Chung
