How to update your Fitbit smartwatch or fitness tracker

Fitbit occasionally releases software updates for its devices that bring new features and bug fixes.

For instance, the Google-owned company recently rolled out a Fitbit OS 5.2 software update that adds high and low heart-rate notifications to the Versa 3, plus Google Assistant can now speak audible responses on some watches. If you’re curious about what’s changed in the latest Fitbit update, plus how to get the new software on your device, here’s everything you need to know.

For those of you looking to see which Fitbit device you own, see our guide that compares all the best Fitbit smartwatches and trackers available.

How to update your Fitbit device

Fitbit releases updates to all customers “in phases”. So, If an update is available but you don’t see it, simply check the Fitbit app again later.

Fitbit device

Fitbit recommends you charge your device and confirm you have the latest version of the Fitbit app installed on your phone or tablet.

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. Updates may take up to an hour or more to complete. Fitbit warns that if you update your device at midnight (when your step count resets), you may see an inaccurate step count for 24 hours. So keep that in mind.

Fitbit app

Firmware updates become available if you allow the Fitbit app to run in the background. With your charged Fitbit device nearby, open the Fitbit app.

  1. Go to Today tab   > your profile picture > your device image.
  2. From there, tap the pink Update button.
    • This option only appears if an update is available.
  3. Follow the on-screen instructions.
    • Keep the device close to your phone, tablet, or computer during the update.
  4. An update progress bar will appear on your device and in the Fitbit app.

Note: If you’re still having trouble, see the following Fitbit support page: Why can’t I update my Fitbit device? Those of you looking to update your Fitbit.com dashboard can go here for more details on how to do that. You can also learn how to find your dashboard version number here.
