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 and runs, 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 iPhone 5s, 6, and 6 Plus. 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.

ELEVATE YOUR TRAINING: Track stats and routes for runs, hikes, and walks with MobileRun. See your pace, splits, time, distance and route maps in real time. Record workouts and use the monthly exercise calendar to follow your training program. (Continued use of GPS running in the background can dramatically decrease battery life.)

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.

Customer Reviews

Like to love.

I am using the Fitbit app with my Fitbit Flex. I love being able to see the power level of my Fitbit so I can prepare to keep it charged. The app is laid out fairly well and easy to use but I find I have to back in and out of sections to set goals. It would be nice to have a base section where I could easily see all of this information. One thing that kept me from getting this product for so long is the lack of diabetic support. I would really like to be able to track my glucose through the app with the ability to make comments, add times, set goals, etc. I understand it is possible to do this on the Website but that takes away from the convenience of the app. I do find the app to be motivating as well as the product as I keep it running while I work out. I find myself aiming to hit a full extra mile, rounding out those last 1,000 steps, etc. I am very surprised and so happy to find that it does not drain my battery using the app or syncing the Fitbit. Absolutely love but would like to see a few updates and features.

A few problems but overall does the job

I love my Fitbit and I really like this app. Overall it does everything I need it to. But I do have a few complaints:

When my charge HR loses my heart rate in the middle of a workout the app just registers it as zero so there's a massive drop on my workout log where it should just slowly decrease until it finds the heart rate again.

Another issue is also with the workout tracking: why do you categorize every workout in terms of distance? Not everyone stays fit by running/walking/jogging etc. This is especially annoying when you have a tag line like "Find your fit" but don't cater to different types of fitness. Even the database of exercises doesn't include lifting weights. I lift and do cardio. So distance isn't my primary concern at all. You should allow for workouts to be categorized by average HR or time spent instead of lumping them all into distance.

That being said, I've tried a lot of other apps paired with my Charge HR and none really even come close to proving me the depth of data I get with this one. I like the app but I wish there were more options for people like me who don't solely do cardio. Considering I got a Fitbit to track my workouts and they aren't cardio-based this has been my major disappointment.

Will not sync

I've had my Fitbit Charge since April, and it has worked fine until a week ago. It has not been able to sync to my iPad and I have desperately tried everything in attempt to make it work, including redownloading the app several times. I eventually removed my Fitbit off of my account, but I lost patience when trying to reload it back on because it took over an hour but still would not properly connect to my account. I have kept my Fitbit in stellar condition, but now it is almost useless since it won't sync. Sure, I can still see my steps taken directly from my Fitbit and can still log calorie and water intake, but I can't see my progress, see how well I slept, set silent alarms, get call notifications, track how long I exercised, etc. so it makes me frustrated that my $140 activity tracker just turned into another watch.
