Fitbit occasionally releases free feature enhancements and bug fixes for your device through firmware updates. For details about each update, see What's changed in the latest Fitbit device update? If you're looking for troubleshooting instructions, see I can't update my Fitbit device.
How do I update the firmware on my watch or tracker?
Start charging your device before updating it, since a firmware update can take several minutes to an hour and is demanding on the battery. Note that if you update your device at midnight (when your step count resets) you may see an inaccurate step count for 24 hours.
Choose a section below for steps on how to start the update.
- Verify that the latest version of the Fitbit app is installed on your phone or tablet.
- With your charged watch or tracker nearby, open the Fitbit app.
- Tap or click the Account icon () > your device image.
- Tap or click the pink Update button. You'll only see an option to update your device if an update is available.
- Follow the on-screen instructions and keep the device close to your phone, tablet, or computer during the update. Note that a firmware update may take up to an hour to complete. If the update is slow, don't remove your device 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 Fitbit device?
- If your device came with a wireless sync dongle, make sure it's plugged into a USB port on your computer.
- Verify that you're using the latest version of Fitbit Connect:
- Click the Fitbit Connect icon () located near the date and time on your computer. If you can't 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 syncs your watch or tracker and then looks for a firmware update. If an update is found, Fitbit Connect displays a progress bar until the update finishes. If your device has a screen, you'll also see a progress bar there.
- Keep your device close to the computer during the update. When the update is done you'll see a confirmation message and your device will restart. Note that a firmware update may take up to an hour to complete.
- If the update fails to complete, try again. If it fails a second time, see Why can't I update my Fitbit device?
How do I update the firmware on my scale?
Your Fitbit scale automatically checks for updates on a daily basis. When an update is available, the scale downloads and installs the update without any input from you. If you step on your scale and see a progress bar, the scale is currently checking for updates and you need to wait until it's done to complete a weigh-in.
How do I find my current firmware version?
From the Fitbit app, tap or click the Account icon () > your device image. You'll see the firmware version number under your device's name.
On the fitbit.com dashboard, click the gear icon () and select your device to find the firmware version.
Note that with Fitbit Blaze and Fitbit Surge you can swipe to the Settings screen on the device to see your current firmware version. On Fitbit Ionic, find the firmware version in the Settings app > About.
