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.)

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.

1st and 2nd Fitbit battery fail

What's going on with Fitbit Flex? Got my first Fitbit Flex as a gift on Mothers Day. I After about 10 months I noticed the battery would only hold a charge for 2 or 3 days rather than the usual 4 or 5. Also, it stopped recording the sleep data. I went through the troubleshooting steps (clean/reset) numerous times. After 13 months the thing wouldn't hold a charge for more than 24 hrs., didn't log the activity correctly and always showed the "no battery" symbol on the app. After some hassle w/Fitbit, they kindly replaced the Fitbit Alta, including all the accessories. Now, after less than ONE month, the bit is not holding a charge for more than a few hours, tracking data Is incorrect. I've done the cleaning and reset steps but it's not giving more than one blinking "charge" light. I'm deeply disappointed. I really rely on the stats to measure my activity and to motivate me to exercise. I haven't abused the device in any way -- haven't dropped, banged, submerged my Fitbit in water. It's been less than a month since I got the replacement! I will contact Fitbit AGAIN but this is not good.

Only one little problem

Yesterday I spent a good long while on the phone with a representative from Apple. My coveted Apple Watch decided to fall apart. After spending over $600 on the stainless steel model I was not willing to spend $200 to get it fixed. I guess after having had it for two years I just didn't want to put the money into it. I thought I'd give something else to try. I really wanted a little bit more insight as to my sleep habits and Apple does not offer that. I went to target and I purchased my blaze. Looks good and works great. My only complaint is that the app doesn't allow you to go from calories in vs calories out to another type of diet. I personally am on the ketogenic diet. Although it does give me my macros I would love to see it let me change to a more carbohydrate based format then a calorie based format. Other than that. It's all good.

Add levels to people's profile

It's okay... it's not motivational. I honestly wish there was a leveling system. Certain distance or steps to gain level so people feel prestigious for their hard work and a motivation to keep going. Leveling system!!!! If you do it, I'll buy my mom a Fitbit lol. I'm just so bored and there's no point of wearing it or opening the app. I just use the watch for the time. The features don't appeal to me enough bc I don't get to see a total steps or distance or anything, just charts for the month or week, very stale in my opinion. All opinion. I like the social media part. Add leveling system, everyone would go CRAZY for it lol <3 much love for your product just add leveling
