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.

TRACK RUN STATS IN REAL TIME: New MobileRun lets you use GPS to track your pace and routes during runs, walks, and hikes.

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

CORTANA BETA (US, UK and AU 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.

    Love it minus two significant issues w Windows phone: 1 doesn't track cycling or swimming; only run /walk 2 No caller ID And as an aside nothing to address these issues in FAQ or Forums.

    App has more functionality than advertised on their site, and it beautifully incorporates the windows phone style tiles. Very glad to see windows phone getting a slick first party app!

    Pretty nice app. I don't have a fitbit yet but the tracking it does using my phone is pretty accurate and nice. I love being able to scan barcodes for food logging quickly. A feature I'd like to see, compared to other food logs, is a log of the days total fat, carb, and protein intake. Calories in and out are nice to see but more info would be nice for an overall picture of health. Especially, for vegetarians needing to watch protein or those trying to go low fat for heart purposes. One glitch, it needs me to open the app daily to keep syncing my steps for some reason on 635.

    Solid app. Please add ability to pin things like track exercise and add food as tiles.

    Worked great on 8.1 Denim. On 10 preview, MobileTrack is reading but not syncing to my dashboard. Please investigate and fix. Thanks.

    Good app for tracking walks and runs but it would be nice to be able to track bike rides as well. Also cannot use voice updates when playing music.
