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 fit bit....hate the issues

Many of my friends use different versions of Fit Bit. We are in constant competitions and it's great. Every now and again, the fit bit will not sync. My fit bit HR will show my steps however, what is displayed on the app is off by thousands of steps. Sometimes, my app will show "syncing", state it's "connected" but reflect zero steps when on my wrist I could have 8k steps. If that's not the issue, then it just won't sync at all. Twice, my fit bit battery life was half full when it randomly shut off until I charged it again. I have deleted the app, re installed it, restarted my phone, allowed my fit bit to die, recharged it. All to continue to have the same issues. Someone please fix this. It's ridiculous. I love the fit bit options and tracking but these issues need to be cleared up.

Love-Hate Relationship

I have had my Fitbit flex since Sept 2013. I love how I am able to see my movement or lack thereof at times. I love the accountability and friendly competition that comes with the connecting of friends. With that being said I'm noticing friend with the Charge and Charge HR (and potentially other models) are showing as unranked on my friends list and others, when they band clearly shows they are actively moving, this is a problem for me because it lessens the accountability I love so much, please fix this so this can be a love relationship and I can give a 5 star review.

Love it!

I love everything about this device! It was very easy to setup, easy to log/watch your progress & I really like the heart rate feature. At the click of a button you know your heart rate. This is especially important during workouts!
I gave it 4 stars & not 5 because the steps are not accurate. I was at 9995, 5 short of 10,000 & it buzzed my while I was driving - clearly not walking - that I reached the goal of 10,000 steps. As long as you're aware the steps are off a bit it's a great device!
