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 Smart Scales 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.

FEMALE HEALTH TRACKING: Log your period, record symptoms, and opt into receiving push notifications two days before and on the day of your predicted period start date. This allows you to have the opportunity to compare all your stats in one place.

Great app but novelty wears off quickly

When I first got my Fitbit I used to sync everyday, track my heart rate, calories, compete against friends each week as to who could do the most steps. Now all I use it for is tracking my sleep and as a watch. Sometimes I’ll have the notifications on and have my phone on Bluetooth so I get the message or call notifications, but often I’ll have this switched off as while I’m at work I find being prompted to hit 250 steps every hour a bit distracting. It would be good to have a feature where you can select which notifications you want, so I could see my messages and calls, but not the step reminders.

It’s a great bit of kit and it’s obviously very popular but once the novelty wears off it pretty much becomes a watch. There used to be an incentive as the Fitbit app could be synced with the Lucozade Sport app where you could be entered into prize draws if you hit a certain amount of steps daily and/or weekly, but unfortunately Lucozade have finished their promotion. Perhaps Fitbit could consider partnering with another company to rekindle those incentives. I did far more steps each week and won a few nice prizes too, so it definitely encouraged me to be more active.

Really helpful

I have a chronic illness and my Fitbit HR is so useful in so many ways. Helps me monitor what’s helping and what is not. Such as how fixing a B9,12 iron deficiency helped my step count and a dip in step count on autumn led me to discover my vitamin D was low. I use so many of the functions such as sleep
Monitor to improve sleep, HR and steps to pace and the logging of food has really helped me keep healthy diet and also lose weight as I’ve not been so active and it’s helped stop calorific snacking. The period app is also really useful. I use this app more than any other and it’s really helped me manage a complex chronic illness. So useful. Best health buy I’ve made and the app is so easy to use. The app is free to try to see if it could be useful before buying a Fitbit, which is what I did. I got a Fitbit HR specifically do I could monitor sleep. If it adds a function to analyse vitamin intake from diet and supplements this would be amazing. It’s the only thing I think is lacking. At the moment it’s focussed on calories and carbs/protein/fat which is great for following keto diets, but I’d really like it to work out my vitamin intake to help me improve my deficiencies more naturally than supplements. Excellent app and device. Highly recommended. Used it non stop over 18 months now.

Serious app problems?

Let me start by saying that I love Fitbit and have both a charge 2 and an ionic. Also thinking of getting a verse or charge 3 and regularly recommend Fitbit to friends and family. BUT and it’s a big BUT since last October I have had serious problems with either devise connecting and syncing to the app. Hence the 2 star review. The charge 2 is better than the ionic. Syncing is erratic and completely unreliable. I cannot rely on the ionic to even tell the time accurately and cannot use the alarm function as it loses time when it doesn’t sync and wakes me up late! I have reported this to support and although they are easy to contact (through Twitter messaging), respond in a timely way and seem keen to solve the problem - they actually have no idea why this is happening and cannot resolve it. I have come to the conclusion that this is an app flaw rather than a hardware problem. Sorry Fitbit but this fundamental lack of reliability is just not good enough. I won’t tolerate it much longer if you can’t sort this out.

Update: seems like a lot of other users are having problems syncing. I had problems for a couple of weeks last October 2018 and now for the last 2-3 weeks. Others reporting same problem recently over the same time scale. Not once have Fitbit support told me others have reported the problem! Annoyed. This is making my two Fitbit devices unusable.
