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.

    Great as an app and even better with a fitbit charge hr. My wife has one too and it has certainly encouraged us both to become more active on a daily basis.

    Accurate pedometer. Can't add food via Search. Must use web. Can't delete food items from recent (added via web not from app) Voice commands are beta and don't work at all. Conclusion: Nokia device with MSN Health and Fitness app does the same thing without eating up battery via Bluetooth (fitbit connection). Only bonus to fitbit is minimalist pedometer when phone is not with you.... Which is virtually never.

    I really like this app I have lost half a stone and really think this app has helped. But today its stopped working.. It won't open... I have weight to lose please fix !! 😐

    Works well except for one big annoying software conflict. When listening to music with headphones, and when the app auto syncs, my volume reduces slowly to zero, and I cannot turn it back up without a reset or turning off Bluetooth. Turning off auto sync or Bluetooth while listening to music stops the problem from happening. I am on a Lumia 930 Windows 8.1. Very annoying and took ages to figure out. I thought I had a hardware fault, and was preparing to return my phone. Instead I have a fitbit app fault.

    Quite pleased with this app, I'd like to see itt expanded a little though, the focus is on weight as a whole and not fat which id prefer. It would also be useful if it summarised your daily intake, carbs-protein-fat throughout the day and maybe even allow us to set an alarm to indicate that your calorie intake is in or out of the zone.
