How do I update Fitbit devices?

Before you begin the firmware update, charge your device and confirm you have the latest version of the Fitbit app installed on your phone or tablet. Note the following:

  • If you update your device at midnight (when your step count resets) you may see an inaccurate step count for 24 hours.
  • Updates may take up to an hour or more to complete.
  • Let the Fitbit app run in the background on your phone, which allows a small portion of the firmware update to download to your Fitbit device each time your device syncs

To update your device:

  1. With your charged Fitbit device nearby, open the Fitbit app.
  2. Tap the Today tab  Devices   your device image.
  3. Tap the pink Update button. This option only appears if an update is available.
  4. Follow the on-screen instructions and keep the device close to your phone, tablet, or computer during the update. After you start the update, a progress bar appears on your device and in the Fitbit app until the update is complete.

How do I interpret the severity of a Fitbit security update?
Rating Definition
Critical The security update patches a vulnerability that, if exploited, could allow attacker-supplied code to gain unrestricted access and potentially go undetected by the customer.

We recommend that you apply a critical update immediately.
Important The security update patches a vulnerability that, if exploited, could compromise data security, potentially allowing access to confidential or sensitive data but stopping short of full code execution.

We recommend that you apply an important update immediately.
Moderate The security update patches a vulnerability that carries less risk than important or critical updates, or one that is significantly mitigated by configuration, warnings, or other factors.
Low The security update patches a vulnerability that carries minimal risk or one that is comprehensively mitigated by existing measures, is extremely improbable, or is difficult to exploit.
