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.

    Fitbit is a great brand. My fitbit charge hr is an amazing fitness watch. But this app, maybe solely for windows, needs major improvements. The only way I can get my device to quickly sync to the app is to uninstall, then reinstall the app. What's that? Reset the device you say? Sorry, only a temporary solution. Eventually you end up right back to syncing issues mere weeks (or less) later. My only other gripe I have with the windows app is that you can not scan barcodes of food. It does nothing, recognizes nothing. Some of the calories are off on the food diary. For example, calorie specific food items like the 100 calorie packs or the 90 calorie fiber one bars should actually reflect the same amount of calories as the package claims, currently it seems as if it tacks on more calories than it should. My other complaint with this app is that it doesn't offer all the same abilities as perhaps you could get with an Android device. The caller ID feature only works for a limited number of devices.

    It's great to see the constant updates to an app which is already fantastic. My Fitbit had helped me live a healthier lifestyle over the past two years. The Windows app is well laid out and intuitive. Keep up the great work.

    Pretty good at the moment Fitbitcharge HR, but can't get the id notification caller on my WP. MAYBE BECAUSE THERE IS NO WINDOWSPHONE CAPABLE OF GETTING THE NOTIFICATION!!. pls update WP.

    Lousy app, the sink between the charge and the computer stopped working on 6/16... Apparently no support for Windows, period. I'll switch to the new Microsoft Band this fall.

    Love this app but only gave it 2 stars because it is very slow to do things. Gets frustrating

    My daughter gave me fitbit for mothers day. I love it. We compete with each other. I highly recommend this exercise tool.

    Slow to find tracker. I've never gotten more then a couple days out of flex charge. Whoever made that claim from the company is a flat out lair. Maybe its the phone draining it faster than usual. I never got close to 5 days on IOS either.

    App does not sync my charge HR and my Nokia Lumia icon.
