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.

    Works great with my fitbit flex and syncs seamlessly however needs a UK food bank as it's difficult finding accurate measurements using the US one. Currently using myfittnesspal and manually entering the data which is tedious.

    No UK food database. It seriously says 'since you're in the United Kingdom, we figure the United States food database is the best one for you'. What seriously?! Was about to buy a Fitbit Flex, don't think I'll bother.

    Stopped working. Was great but just freezes when launched now.

    Really disappointed with the fitbit, only good for logging steps. It never recognizes foods or exercises and it even thinks I've been asleep for 12 hrs! Rubbish!

    Great app. Fit it released an update quickly after I reported an issue. Great customer service!

    Very good app for checking fitness, sleep, daily activity, exercise, and general everyday functions. Living in the UK though, I would like to see a UK food database.

    App fixed after update, works fine now.

    App is easy to use and good fun with friends challenges. WP is let down by the not having the option for call notification, could be really great with my charge, as it could display the number or name if in the phone book when someone calls me. The other issue is the calories its all American, it says use U.S as in the U.k but cant find any of my barcodes even Asda food own brand stuff. If these was addressed I would give 5 stars.
