Live a healthier, more active life with Fitbit, the top app for tracking all-day activity, workouts and health.

Use this app on its own to track basic activity, or connect with Fitbit’s line of activity trackers and the Aria Smart Scale to get a complete picture of your daily stats—including steps, distance, calories burned, sleep, weight, and more.


TRACK ALL-DAY ACTIVITY: Track your daily steps and distance right on your smartphone with MobileTrack for supported Lumia devices. MobileTrack accurately tracks your basic activity when you carry your phone. For more in-depth, all day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker.

LOG FOOD: Easily log calories with a credible food database. 

CORTANA BETA (US Only): Using Cortana and a custom Fitbit voice experience, log foods and set alarms with simple natural sentences.  

ACHIEVE YOUR GOALS: Set goals, enter your weight, record your sleep and start a food plan. Then view your progress and track your trends with easy-to-read charts and graphs. 

COMPETE WITH FRIENDS: Enlist friends and family to help you reach your goals by sharing stats, joining fitness challenges, direct-messaging each other, and competing on leaderboards.

SYNC WIRELESSLY: Fitbit trackers continuously sync your stats with your Windows Phone to give you real-time access to your progress without plugging in.

OUTSMART YOUR WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, activity and more.

Fitbit requires Windows Phone 8.1. Lumia devices need to be running the Lumia Cyan firmware.

    Great app. Just waiting for support for notifications on my fitbit charge.
  • by Jose R. 11/21/2014
    The app design is very good! But they say this version has background sync, which for some reason is not working at all on my Lumia 920. Also, the LiveTile won't update unless I launch the app, so not much point in even using the not-very-live tile other than just a shortcut to the app. Other than that, I really like the rest of the app's functionality and design. If LiveTile and background sync worked, it'd be a 5 star rating for me.

    Had some issues with initial setup of my Fitbit device. (Ended up completing that process on a PC), but after the device is linked to your account the app performs admirably.

    I think this app is worthless....totally inaccurate counting because I do not have same activity level day in and day out. I'm still searching for a health app....would love one with step counter....walking is a large part of my job.

    Fantastic App! Great UI and easy to use! So excited to sync up my fitbit.
  • by Patrick 11/14/2014
    Great app for syncing with the Fitbit and viewing my stats. The only reason it doesn't get five stars is the app doesn't consistently background sync, and the live tile is often out of sync with the stats I see in the all.

    Nice app layout

    Who can tell me how to syncs on my HTC 8x. It can not be recognized by the Bluetooth.....thx!
  • by Andrea 11/13/2014
    Love that my steps show up when the app is pinned as a Live Tile. I wouldn't mind if the app was updated with MobileRun. Totally staying motivated with my Flex even more than ever now that I have the app installed.
  • by Sridhar 11/13/2014
    The application works well with my flex. Gives me a lot of statistics but not sure if the reports are accurate. Tried my best to report 100% of my calorie intake but the Application says I'm burning more calories than i consume. My weigh scale says otherwise 😌
