Fitbit occasionally releases free feature enhancements and bug fixes for your tracker through firmware updates. For details about each update, see What has changed in the latest tracker update? If you're looking for troubleshooting instructions, see I can't update my tracker.
How do I update my firmware?
First make sure your tracker is charged, since a firmware update can take several minutes and is demanding on the battery. Be aware that if you update your tracker at midnight (when the tracker resets its data) you may see an inaccurate step count for 24 hours.
Choose a section below for steps on how to initiate the update.
- Verify that the latest version of the Fitbit app is installed on your device.
- With your charged tracker nearby, open the Fitbit app.
- Tap the pink arrow next to the tracker name at the top of the screen. If you don't see an arrow, no update is available.
- Follow the prompts onscreen and keep the tracker close to the mobile device during the update. If the update is slow, don't remove your tracker from your account as a troubleshooting measure.
- If the update process won't start or if it starts and then stops, see Why can't I update my tracker?
If you're updating an Alta with a Windows 10 PC, make sure the wireless sync dongle is plugged in.
- If your tracker came with a wireless sync dongle, make sure its plugged into a USB port on your computer.
- Unless you installed Fitbit Connect for the first time recently, verify that you're using the latest version:
- Click the Fitbit Connect icon located near the date and time on your computer.
If you cannot find the icon, you may need to reinstall Fitbit Connect from http://www.fitbit.com/setup.
- Click Open Main Menu...
- Click Troubleshooting.
- Below the Fitbit Connect number, click Check for updates.
- Go back to the main menu and click Check for device update.
- When prompted, log in to your Fitbit account. Fitbit Connect will sync your tracker and then look for a firmware update. If an update is found, Fitbit Connect will display a progress bar until the update finishes. If your tracker has a screen, you'll also see a progress bar there.
- Keep your tracker close to the computer during the update, which may take several minutes. When the update is done you'll see a confirmation message and your tracker will restart. You're all set.
- If the update fails to complete, try again. If it fails a second time, see Why can't I update my tracker?
How do I find my current firmware version?
In the Fitbit apps, tap or click the Account tab and then tap your tracker tile. You'll see the version number below the most recent sync time.
On the fitbit.com dashboard, click the gear icon in the top right and find your device settings.
Note that with Fitbit Blaze and Fitbit Surge you can swipe to the Settings screen to see your current firmware version.
