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, 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.

    I love the fitbit. But I was wondering why the charge caller ID will not work on Lumia 1320. Does anyone know about this plz respond thanks.

    This app is fantastic! I love the Cortana integration.

    Great app. Mostly works. I'm running Denim and for some reason my steps are not being counted toward a Daily Showdown competition I'm part of. Other than that one glitch, it works fine. I'm glad they took the time to make a Windows Phone app for us.

    I love this app.! It sync's perfectly with my Charge HR. Just wish I could get notifications on my fitbit. I really like windows phone's but definitely thinking of going with Android or iPhone for that reason.

    This app is amazing!! I can easily see what my tracker is capturing and logging in is super simple. To be able to scan the UPC to get the calories from bought food makes logging in even easier. I love being able to have it on my phone, making updates and information easy to access and keeping me informed of my progress.

    Integrates nicely with Windows Phone and works great! However the live tile seems to never update steps taken unless I open the app...

    The app could not setup my device. It would just crash every time. Had to set up my Charge HR with my PC. The buttons in the app just won't work. Want to log food, water, weight? No go. The app simply does not work.
