How do Fitbit trackers sync with Android devices?

« Go Back



The Fitbit app for Android is available on over 150 Android devices. It uses Bluetooth Low Energy (BLE) technology to sync with your Fitbit tracker.

Will my Android device sync with my Fitbit tracker? 

For the latest list of supported devices, see To sync with a Fitbit tracker, an Android device must have both a BLE radio and software support. BLE is an optional component of Bluetooth 4.0, meaning not all devices with Bluetooth 4.0 include BLE. Some devices have the hardware but not the software, while others have both but software bugs prevent it from working. If you're buying an Android device to use with the Fitbit app, make sure the device appears on our supported devices list.

How do I sync my tracker?

To initiate a sync, just open the Fitbit app for Android. As long as Bluetooth is enabled on your Android device and in the Fitbit app, your tracker should sync. If your Android device is in airplane mode, it will not sync until you turn off airplane mode, or until you manually turn on Bluetooth on your Android device.

How often will my tracker sync?

Your tracker syncs with the Fitbit app for Android every time you open the app. If you've had the app open for a while and want to initiate a new sync, tap the menu button on your Android device, tap Devices, and then tap your tracker to see an option for syncing immediately.

By default, the app syncs periodically with your tracker even when the Fitbit app is in the background. Known as “all-day sync,” some customers find that this feature causes the battery on their Android device or their tracker to drain more quickly that normal. If this happens and you want to disable all-day sync, just tap the menu button your Android device, tap Devices, and then tap your tracker and turn off all-day sync.

I'm pretty sure my device supports BLE but it's not on your list. What do I do?

We are continually testing new handsets for Fitbit compatibility, so there is always a chance you have a working handset that we haven't certified yet.

If you think your handset supports BLE and would like to find out, please consider joining the Fitbit beta program at!forum/fitbit-android-sync-beta. (Download the beta app by following the instructions as the top of the forum.) The beta version of the app may support your phone even if the production (public) version currently does not.   

If you find out that your phone does sync over BLE successfully and is not yet supported in the production app, please post your results in the Beta Forums. We will work on getting the device supported as quickly as possible in the production app. 

I installed the Beta app but my phone still doesn't sync. What do I do?

First, make sure you are really running the beta app:

  1. Open the drop-down menu on the main dashboard screen.
  2. Choose "Help" and then "Fitbit app."
The screen should show your Fitbit app version. If you are running the beta app, you will see a small "Beta" label at the end of the version number. If you don't see the "Beta" label, the beta app may not have installed correctly. (Sometimes there can be a time lag between when you sign up for the Android Beta Google Group and when the Play store is ready to offer you the beta build.) Try deleting the Fitbit app and reinstalling the beta app again after 15 minutes.

If you are running the beta app and still cannot sync over BLE, then your phone either does not have BLE support or does not implement it correctly because of the following scenarios:

  • If you don't see any syncing options or cannot pair (connect) with a tracker, the beta app did not detect the presence of any common BLE libraries.  Either your handset doesn't have BLE hardware at all, or doesn't have a library that enables BLE. 
  • If you can start to sync or pair your tracker but neither action completes successfully, your phone has BLE hardware and a BLE library, but the implementation may have bugs that prevent it from working correctly.
