Small steps. Big impact.


Wrist Tracking and More with Fitbit Flex


We are so thrilled to be announcing Fitbit Flex to everyone. For many years, we managed to keep our research team very busy developing the technology to make Flex, our first wristband product, work the way we want it to work. We wanted to make sure we captured actual steps taken without capturing “steps” from everyday hand motions, like typing, gesturing, or even eating.

One big challenge we faced was that while we managed to not calculate steps from these sitting activities (eating), and avoid steps from driving, we wanted to capture steps when you’re walking but your hands are held still. When would this happen? Well, walking with a stroller of course! It’s actually a common complaint among wrist tracker users. To determine the right algorithms to sense and capture these steps required lots of development and testing.  If you have been near our office in San Francisco, you would have seen many researchers running up and down the street with strollers, wired with all these gadgets to see how we can capture those movements.

Additionally, we waited until now to launch a wristband because we wanted to be able to offer wireless syncing with Android phones as well as iPhones, iPads, and iPods with Bluetooth 4.0. We’re very excited to announce that our products will start syncing with the Samsung Galaxy SIII and Samsung Note 2 in late January/early February, and more devices will follow soon! Viva la mobile!

    Any plans for a Windows Phone 8 app?
    This seems like a great way for me and my wife to track how active we are.

    I’m very excited to use the wristband in my day to day activities.

    Please keep all up to date.

    Dang I really want the Flex! It’s exactly what I’ve been looking for after buying, being unhappy with, and returning the Nike Fuelband and Larklife. Please tell me it will be available really soon. Like by the end of January! If not, can you provide at least a hint as to when we can expect it?

    Yay! I have a Fitbit One, but am really excited for the wristband. I was wondering, though, how small is the small? Because my wrists are teeny tiny.

    I can not wait for the Flex. I am totally addicted to my fitbit. Great job listening to your customers wishes!

    Please consider the Android flagships first (Google’s Nexus Line e.g. Nexus 7 tablet, Nexus phone…) since they are pure unadulterated Android software.

    I dont expect to see my bionic supported soon, but if I can see your gadget on my Nexus tablet, I’m buying!

    I am very excited that fitbit will be able to sync with Android devices. I have been waiting to buy this product because I am an Android user. I can’t wait!

    Can you please let me know when Fitbit Flex is scheduled to be available in Australia? Even to purchase online for delivery in/to Australia?
    Many thanks.

    I love that it will track walking while pushing a cart or stroller, my current watch pedometer doesn’t.
    Two questions: Will it track stairs like your other Fitbits? Will this synch with Windows Phones too?

    Ooooh… please hurry on the Bluetooth syncing via Android thing! I’ve only had my Fitbit for three weeks, but I love it (have lost 8.5 pounds already). I just got rid of my iPhone 5 in favor of the Samsung Galaxy Note 2, and literally my ONLY issue is that I can’t use it to sync my Fitbit. Soooo glad this is going to be rectified soon. Hurry, guys, hurry!!!

    This is great – I was wondering when it will be released in the UK? I am in the market for one, but will now wait for this I think, instead of the fitbit one – the wristband seems like a much better form factor.


  14. February 4, 2013

    Release the Kraken! Just kidding. But seriously, hurry up! My wife will love this. Win-win for me!

    I have the same question about stairs. I’m trying to decide which would work better for me. I live in SF, and climbing stairs is a constant activity, so I’m trying to decide whether to get The One, or wait until the Flex is out. Any thoughts you might have would help. Thanks.

    I have a windows phone 8. But I think for Fitbit to sync it needs Bluetooth 4.0 which is not available on windows phone as yet.

    Looking forward to Android expansion. Hoping you’ll support many of the bluetooth 4.0 models, especially the RAZR series. Enjoying my FB One experience so far.

    The flex is just what I am looking for. I see it is water resistant. Will I be able to shower and swim with it on?

    It’s been really exciting to watch the development and growth of the company the last few years. I feel thrilled to have been a loyal user since receiving my first fitbit back in December 2009. Now I’ve preordered the flex and am anxiously awaiting its arrival just like I did for my original bit. Just hope it’s not 9 months again. Haha. Would love to be a beat tester if any are needed. Best wishes for another successful launch.

    When in “Spring” is the Flex coming out. It seems like forever since I pre-ordered. I love my One – but managed to lose the charging cable and it is on back order, so my One is dead and I’m going through FitBit withdrawal!

    I was wondering how the flex wristband would capture steps while walking on a treadmill and holding the side or top front rails (vs swinging arms freely). Will it be handled the same as pushing a stroller? Because I am considering the Flex for exercise & sleep tracking, not calorie counting – use Wt Watchers points for diet… Thx. Eager to see what comes out.

    I gave the Fitbit One to my husband and sister for christmas and am now buying the flex for my mother! I love it especially because I can see how many steps she is taking a day to make sure she’s staying active. The scale is great and so easy to use what a wonderful addition!! Are there any future plans to have bar code scanning for food tracking? It seems to be the only thing missing!!

  27. Andi permalink

    Will the “FLEX” be released in bigger sizes or with an extension bit? It needs to go bigger than 8.2in as the current max size!

    Not everyone has tiny wrists ;)

    I would give up my cell phone before I would ever give up my Fitbit. I have had both models and chose the wrist band. It never comes off except to be charged.

    I am enjoying the flex. At the present time it tracks all the activity (or lack of) that I need. Being an engineer myself, I anxiously await all new and useful technology.

    For those of you who have trouble putting on the Fitbit Flex, try applying a small dab of hand cream on the clasp. It pops right on and stays on without any trouble at all.

    I really like the idea of the flex and I want to purchase it but it would be nice for those who already own fitbits to have a trade in program or just a loyalty discount for purchasing new or additional fitbits. I love my fitbit one but I am very tired of misplacing and losing it for weeks at a time! Just a suggestion/idea.

    I just got my FitBit Flex yesterday. I absolutely love the sleep feature – this is a first for me. I have tried other tracking devices and this is by far the best ever – even after just one day. The fact that you can sleep, shower and wear all day is great. You never forget to put it on. I really like the calorie tracking feature – calories out vs. calories in. I finally feel like I have the all-in-one device I have been looking for.

      I’m really interested in the sleep feature of theFitbit Flex, but how well does it work? Is it accurate? And what about the no sound wake up alarm?

    I love having the flexbit much better than the fit bit one tracker. I always know it is there. I just wish there was a fancy band to look more like a watch band or an evening piece of jewelry. I wear it all the time but wish that I had more band options. I did purchase the 3 color bands and the pink band also. Now I have a spare flex bit but I wanted to have the pink band really bad. Obsessed I guess.

    I am recovering from a pylon fracture of my right ankle. Have been going to the gym almost daily to use arc machine, elliptical, and treadmill. Need to use machines as I still have impaired balance and must hold on when walking, stepping, gliding. I suspect my flex isn’t accurately tracking all these steps. Any suggestions?

    I am the proverbial “couch potato” due to retirement (aging), chronic pain in my feet and not having a plan. Being a retired Registered Nurse, I know better. I am not practicing what I am preaching. I am thrilled to get my Fitbit Flex today. I plan to “get with the program” and cut calories and increase my activity. I can already tell that just by wearing the band, it is reminding me to move more and watch what I am eating. I’m a little funny about fashion too, so I can see me ordering colors. Hey, how about leopard or zebra??

      I just purchased my Fitbit Flex today. I too am an RN, just not yet retired. 34 years down and 10 to go. I am looking for someone who might be a support/friend to me who also uses the Fitbit. I haven’t seen one before now, and don’t know anyone that has one. What do you think?

    • Marguerite S permalink

      I hope it has worked as well for you as for me. I had lots of pain in my legs and feet. Got the fit bit Force in November 2013 and now am up to 20,000 steps a day. And, I walk outdoors and live in upstate New York, its cold, dark, snowy and I don’t want to go out at time, but push myself to keep my numbers up in the on line communities. Love this thing.

    Great job on the Flex Wristband ! I waited, didn’t want the Belt Clip. Just bought two, one for my wife and I. Just ordered the scale. Thank you !

    My son gave me the Fitbit Flex for Christmas. So far, I am loving it! I like the ability to track not only activity, food, and calorie intake, but also sleep patterns. I have never had a tracking device before, but as a 66 year-young female, I will use this device to improve my health and overall well-being. I had a slight issue syncing my device at first, but received an almost instant reply to my email request for help. Thank you for running a company that actually cares about the people who are using its products!
