Live a healthier, more active life with Fitbit, the world’s leading app for tracking all-day activity, workouts, sleep and more. Use the app on its own to track basic activity and runs on your phone, or connect with one of Fitbit’s many activity trackers and the Aria Wi-Fi Smart Scale to get a complete picture of your health—including steps, distance, calories burned, sleep, weight, and more. TRACK ACTIVITY: Accurately record your steps and distance with MobileTrack when you carry your phone. For all-day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker. RUN SMARTER: Enhance runs, walks and hikes by using MobileRun to track your pace, time and distance. You can also control your music, get voice cues and use your phone’s GPS to map your routes. (Continued use of GPS running in the background can dramatically decrease battery life.) RECORD WORKOUTS: Use your Fitbit tracker to track your exercise, then check the app to see your stats, their impact on your day, and how your performance is improving. MONITOR HEART RATE: Use a Fitbit tracker with PurePulse™ to analyze heart rate graphs in the app. Identify trends, manage stress and see the results of your workouts. Review resting heart rate trends to see when your fitness is improving. LOG FOOD FASTER: Easily log calories with our barcode scanner, calorie estimator, and expanded food database of more than 350,000 foods. See your meal history at a glance, and get nutritional insights. MEASURE HYDRATION: Quickly log your water intake to make sure you’re properly hydrated during workouts and throughout the day. SET & MANAGE GOALS: Create weight, nutrition and exercise goals, and start a food plan to stay on track. Then get a visual picture of your progress with colorful, easy-to-read charts and graphs. SEE HOW YOU SLEEP: Set sleep goals in the app, and use a Fitbit tracker to monitor how much time you spent awake, restless or peacefully sleeping. SHARE & COMPETE: Connect with friends and family by sharing stats, sending direct-messages, and competing on the leaderboard or in Fitbit Challenges. STAY MOTIVATED: Get a nudge in the right direction with notifications that pop up when you’re close to reaching a goal or have already met one. SYNC WIRELESSLY: Fitbit trackers sync your stats to computers and 200+ leading devices so you can continuously track your progress without needing to plug in. MANAGE WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, BMI, lean mass and body fat percentages, and to see your weight trends over time.

  • No longer syncs with Fitbit One after update

    By jott1543
    I used to like the app, though I wish all the features you get online showed up on the app. Some days I’ll have a new icon and then just when I realize how much I like the new thing - poof - it’s gone. But ever since the last update, my Fitbit no longer syncs with the app. The app just continues to “look” for the One without finding it.
  • Good app but won't sync with iPhone - what's the point?

    By User111111111111
    I just got the Alta HR. The app is great, lots of features, took me a while to get used to the interface but good. What I realized today is that it doesn't sync with the iHealth or any of the other apps I'm using to track meals and weight. So I have to separately and manually add meals and weight, etc. for me this is unreasonable and a deal breaker. I'm returning the tracker just because of this point. Plus 4.5 stars for features, negative 6 stars for not syncing seamlessly and requiring to download an app for which to pay or another app to sync.
  • I will never buy another Fitbit Device Again.

    By ThomasSpath
    It work Ok for the first several months, but since IOS 11, I have had nothing but problems with it, and now it just crashes at any given moment. As it was the first tracker I ever owned, I tried very hard to stay loyal to it but it is terrible and not worth using! I just went on a 3 mile walk and the device CRASHED after about 500 steps, so none of my steps after were counted. It was NOT like I was home, so I could plug it in and reset it, which is what I have to do multiple times a week! I’m done. Garmin here I come! Hopefully Garmin makes something that’s at least reliable. Is there any way I can give ZERO stars for this review?
  • No notifications

    By MTshef
    One of the iOS 11 updates broke the feature to get texts and phone calls on my Alta. I can’t even get into the notifications menu in the app. They have been aware of it for several months and still don’t have a fix!
  • Much Improved!

    By Anonmom
    Appreciate the continued Development of this app especially in overcoming bugs. Thanks!
  • Recent update

    By Keke.hemmo96
    Since the update My Mobile sync doesn't work nor does my Fitbit record actual movement time. Ugg I wish pencil pushers would leave things alone.
  • Now I need two hands to see the time?

    By LCfromMD
    I just downloaded the latest update and I hate it. I no longer simply lift my arm to see the time. Now I have to push a button to see the time — that is very inconvenient in the middle of the night, when I have don’t have a second hand free, and when I’m wearing gloves. Please reverse this.
  • Unreal!!!

    By Healthy_gal
    Update needed! I’ve been working w/ my Fitbit one & it hasn’t synced! It’s terribly frustrating! I’ve had this for yrs & I love tracking my sleep & counting my steps! I have to uninstall & reinstall every so often just st for my one to work!
  • Not everyone works 9-5

    By Hubie2003
    Would love to be able to change the time reset from midnight to one of my choosing! Not everyone works a 9-5 schedule and wish this was customizable. Fitbit support advised me to change the time zone, but that would make it incompatible with alarms and a pain in general. I’ve seen many complaints about this issue on Fitbit community pages but they choose to ignore the issue. I will never buy one of their products again.
  • IT’S THE WORST!!!!

    By jillchristine
    My clock face no joke just went away and on the app you can’t pick a background and leave the app. Also thank you #not got the stupid Fitbit ionic it is the worst watch I have ever had🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬first the screen gets cracked like a thousand times but I got a warranty watch. Second my watch gets stuck on the stupid weather app that is not correct at all but I managed to fix it. Third the app is just horrible I would rather have my old Fitbit charge 2 which was amazing 😉 I had no problems with it #better than ionic. Also last thing on my watch that I have right now it is so freaking big that when I ever try to bend my wrist back it clicks the stupid buttons. Now last thing when I try to use my apps it won’t work #I HATE FITBIT STUPID IONIC
