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.

    Everything is brilliant. Love my Fitbit charge and the app now works really well. Very happy with everything. Fitbit is a great company and would recommend to everyone.. On a greedy note, I'd love to see more clock interfaces that include the date, just for a bit of variety.

    Awful app. Absolutely nothing works on it. I try to check details if my steps. Hangs. I try to see the details of my sleep. Hangs. I try to set a goal. Hangs. All I can do is sync with my charge. That's it. Absolute bullsh*t app this is. Please guys don't waste your time, use the app on your i devices or something cuz this app is sh*t

    Good app so far but only 3 stars because of many foods not found and no decimal places in custom food

    Very good but the sleep graphs could be more clear + informative and food input could be easier as many branded foods are not recognised. Also the Fitbit website shows many apps which can be linked but it is not clear how and when done.

    Fantastic app chaps, i have been really enjoying my fitbit in collaboration with my Windows Phone. The Cortana integration works great, the calorie counting is really helping me and is very ready to understand. The one thing that is missing is the voice updates whilst tracking your run whilst you are playing music/podcast. Once this is in, from me it will be 5 stars. I have only been using my fitbit and the app for about two weeks and already it has made a positive impact to my health. Thank you, your efforts are much appreciated.
