Update, Restart, and Erase

Some troubleshooting steps may require you to restart your watch, while erasing it is useful if you want to give Sense to another person. Update your watch to receive new Fitbit OS updates.

Update Sense

Update your watch 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 Sense and in the Fitbit app until the update is complete. Keep your watch and phone close to each other during the update.

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