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.)

LOG FOOD: Easily log calories with a credible food database. Use our barcode scanner or use the quick calorie estimator for customized entries.

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 iPhone 4S and later 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.

Love it for the most part

Although, I've adjusted my settings, and, I don't check my stats frequently on my Fitbit Charge HR, the thing always needs charging. It is supposed to get up to 5 days with normal use and mine gets two tops. I also find it quite annoying that my stair climbing is rarely accurate. I realize that Pausing for to long will throw everything off and even with straight moving, often times, it is not accurate. I also notice that my active minutes is not always accurate and this too has been adjusted in my account settings. However, I do love the heart rate sensor, sleep tracker,calories in verses calories out, how many calories I've burned, miles I've traveled, food log, the water log, and so many cool features. At times the band around my very large lady wrist feels uncomfortable and I purchased my charge HR in the large size. I'm losing weight so hopefully this will get better after time. Overall, I love my Fitbit, it helps to keep me accountable and when I notice I haven't moved as much as a previous day, I want to get some movement in.. During this review, everyone in my house including myself have been pretty sick and I haven't been as active as I was the week before and I can't wait to get moving again!!


Great app! It really helps to add your calories that you eat every day. I know it is not 100% accurate, but it is pretty close and nothing like this is really able to be 100% accurate. It provides a great reference point to make healthier decisions throughout the day. If you really want to track your weight consistently, I would highly recommend the Aria scale. I was hesitant because of the price, but it is very much worth it for the syncing ability. The only thing I would add would be about the weight goal. When I initially set up the weight goal, it allowed me to set a date for that goal to be reached. I recently wanted to change the goal, but now have lost the option to add the goal date. 5 stars.


I'm obsessed with my Fitbit! I could go on and on about my Charge HR, but this is just about the app, which is also wonderful. I love that I can be in challenges with my friends. It always keeps me motivated to move more! The heart rate and steps usually sync very quickly with my Fitbit. For me it never takes more than 30 seconds tops, but I know some people have issues with it taking a while. Calorie burn, stairs, active minutes, exercise all seem accurate to me. The only thing that could be improved is MORE CHALLENGES! It would be cool to compete to get the most active minutes or calories burned for the day. Heart rate in fat burn zones for the longest would be cool. More variety than just steps would be awesome.
