How to troubleshoot when your Fitbit does not sync

Sync troubleshooting checklist

  1. You should check your device’s App Store or Google Play Store for the latest Fitbit app version (for iPhone and Android devices).
  2. There is a recent software update installed on your connected device.
  3. Wi-Fi or mobile data are available on your connected device.
  4. If you are connected to more than one device, Bluetooth should be enabled on every device (some problems occur when Bluetooth connections conflict).
  5. No charge is being drawn from the Fitbit device’s battery.
  6. You have updated the Fitbit device’s software.

In case of sync problems, this is where you should start. Check all items, then follow these troubleshooting tips to resolve the issue.

  1. It is necessary to reset the Fitbit app.
  2. Bluetooth should be disconnected and reconnected.
  3. Your Fitbit should be turned off and on.
  4. The Fitbit app needs to be uninstalled and reinstalled.
  5. You may be able to log in by using another device to access your Fitbit account.
  6. The fitbit apps and Bluetooth settings should not be shared with other Fitbit devices.

Forced syncing manually

Even if your Fitbit tracker is already open, the app may not sync immediately. To force synchronization, tap the membership card icon followed by the tracker name and tap Sync Now.

Check your Bluetooth settings

Fitbit tracks your activity using Bluetooth technology and therefore cannot connect with a device that does not support Bluetooth.

Install the Fitbit app on your device

The official Fitbit app probably was installed on your smartphone, tablet, or computer when you bought a brand new tracker. If you bought a used one, it may not have been.

When connecting to another device and syncing your data with the Fitbit, you need to install a special app.

Resetting your Fitbit tracker

Changing your Fitbit’s settings before you reset it is the most effective way to prevent data loss. When you reset your Fitbit, you will lose all data that has been synced to your Fitbit account.

If your tracker does not have a factory reset option, you can manually restore it. Some trackers, like the Fitbit Surge and Fitbit Blaze, require you to use a paper clip.
