Fitbit may occasionally release updates for your tracker available through the Fitbit Connect software on your computer. Updating your tracker will keep you up-to-date with the latest feature enhancements and product improvements. You can update your tracker using a computer or a mobile device running the Fitbit app. For mobile instructions, see Updating your tracker from your iOS device or Updating your tracker from your Android device.

Updating your Fitbit tracker can take up to 5 minutes and is demanding on its battery. While performing an update on a Force, Flex, or One, we recommend keeping your tracker in its charging cable.

To update your tracker using a computer, follow these steps:

  1. Click the Fitbit Connect icon near the date and time on your computer and click sync now.
  2. Click the Fitbit Connect icon again and click the Main Menu.
  3. From the Main Menu of Fitbit Connect, choose the Check for device update option.
  4. Log into using your account email address and password. Make sure that your tracker is nearby and that your wireless sync dongle is plugged into the computer.
  5. Fitbit Connect will now look for your tracker. If a new update is available, Fitbit Connect will display a progress bar indicating that the update is being applied. Keep your tracker close to the computer until the update is finished.
  6. Once the update completes, Fitbit Connect will display a confirmation screen. Your tracker will now restart, and you can continue using it with the latest update applied.

If you cannot locate the Fitbit Connect icon on your computer:

  • On MacOS: enter "Fitbit Connect" into the Spotlight search box.
  • On Windows: enter "Fitbit Connect" into the Start menu search box.
  • If a search on your computer does not bring up Fitbit Connect, you may need to reinstall it from

If an update failed to complete on your Flex:

  • Your tracker's LED indicator lights may cycle back and forth repeatedly, from left to right. Your Flex no may longer respond to taps, charging, or resets.
  • Try restarting your tracker.
  • Attempt to update your tracker again using a different method if possible (e.g. if you used a mobile app to update the first time, use Fitbit Connect on your computer instead.).
  • If you are unable to resolve this issue, please contact Customer Support for further troubleshooting.
