Learn how to update, restart, and erase Ace 3.

Update Ace 3

Update your tracker to get the latest feature enhancements and product updates.

When an update is available, a notification appears in the Fitbit app. After you start the update, follow the progress bars on Ace 3 and in the Fitbit app until the update is complete. Keep your tracker and phone close to each other during the update.

Updating Ace 3 takes several minutes and may be demanding on the battery. We recommend plugging your tracker into the charger before starting the update.
