Live a healthier, more active life with Fitbit, the world’s leading app for tracking all-day activity, workouts, sleep and more. Use the app on its own to track basic activity and runs on your phone, or connect with one of Fitbit’s many activity trackers and the Aria Wi-Fi Smart Scale to get a complete picture of your health—including steps, distance, calories burned, sleep, weight, and more.

TRACK ACTIVITY: Accurately record your steps and distance with MobileTrack when you carry your phone. For all-day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker.

RUN SMARTER: Enhance runs, walks and hikes by using MobileRun to track your pace, time and distance. You can also control your music, get voice cues and use your phone’s GPS to map your routes. (Continued use of GPS running in the background can dramatically decrease battery life.)

RECORD WORKOUTS: Use your Fitbit tracker to track your exercise, then check the app to see your stats, their impact on your day, and how your performance is improving.

MONITOR HEART RATE: Use a Fitbit tracker with PurePulse™ to analyze heart rate graphs in the app. Identify trends, manage stress and see the results of your workouts. Review resting heart rate trends to see when your fitness is improving.

LOG FOOD FASTER: Easily log calories with our barcode scanner, calorie estimator, and expanded food database of more than 350,000 foods. See your meal history at a glance, and get nutritional insights.

MEASURE HYDRATION: Quickly log your water intake to make sure you’re properly hydrated during workouts and throughout the day.

SET & MANAGE GOALS: Create weight, nutrition and exercise goals, and start a food plan to stay on track. Then get a visual picture of your progress with colorful, easy-to-read charts and graphs.

SEE HOW YOU SLEEP: Set sleep goals in the app, and use a Fitbit tracker to monitor how much time you spent awake, restless or peacefully sleeping.

SHARE & COMPETE: Connect with friends and family by sharing stats, sending direct-messages, and competing on the leaderboard or in Fitbit Challenges.

STAY MOTIVATED: Get a nudge in the right direction with notifications that pop up when you’re close to reaching a goal or have already met one.

SYNC WIRELESSLY: Fitbit trackers sync your stats to computers and 200+ leading devices so you can continuously track your progress without needing to plug in.

MANAGE WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, BMI, lean mass and body fat percentages, and to see your weight trends over time.

Switched back to Fitbit

So I switched from Fitbit to Garmin back to Fitbit. Had I looked at the Ionic prior to switching I may not have switched at all. I disagree with other users that say the Ionic will not receive phone and text alerts. Mine is doing it fine. It was tricky to set up, requiring changing settings on my phone itself, but knock on wood, it works fine. The app is MUCH easier to navigate than the Garmin. My biggest complaint to date is that there is not a way to delete messages received via the Fitbit app. So some other Fitbit user whom you don’t know, can send you an inappropriate message, and you have to see it for the next 30 days. My last one was a user asking if “my pants are on.” I blocked the user, but I still had to see that message for 30 days. Seems like it should be an easy thing for developers, and I have seen many other requests for the same, so hopefully Fitbit listens soon. Other than that, having seen what the competition has to offer, I give the app 5 stars. And I recommend to other users to google how to set up your phone in addition to the Fitbit app so you can receive your notifications. Mine was an easy 3 second fix.

Updates killed the joy

Until last week, I loved my Fitbit Charge HR. The best part was viewing all the statistics via the app on my iPhone. Prior to last week’s update of the device itself (which took three days of googling tips to get it working again), the sync time had slowed dramatically. I’m talking 8-10 minutes to sync compared with maybe 1-2 minutes prior. It had also stopped showing my sleep pattern. I was hopeful that this week’s update would help. No such luck. Still a 10 minute sync, no sleep display, and now it’s stopped displaying hourly step goals. Yes, if tried removing and reinstalling the app. I’ve tried every tip I’ve read here. While I can still view the basic statistics on the device itself, the app became redundant since it no longer shows the added status IF I can even get it to sync. I’ll be moving on to an Apple Watch when my Fitbit dies

Half of a great watch

I love all of the features of this watch. I had the Charge 2 and screen cracked without hitting it on anything. One of my favorite parts of this watch stopped working/ the text and incoming call feature. This happened within two months of getting it. Purchased the new Iconic which has text and caller ID notifications along with a bunch of other notifications from my iPhone 6s. These notifications stopped working in one day. It’s actually the favorite part of my watch. You could easily look at your watch rather than your phone while you’re driving or in the middle of working. Super convenient. Pathetic software. I figured out if I remove the device from the Fitbit app and reintroduce it it will work for another day or if lm lucky two I said...pathetic software.
