How do Fitbit devices sync their data?

Syncing is the process that transfers the data your device collects to your Google Health account. Track your progress, see how you slept, set goals, log food and water, and more in the Google Health app.

Fitbit trackers, watches, and Fitbit Aria Air use Bluetooth Low Energy (BLE) technology to sync with phones and tablets. Fitbit Aria and Fitbit Aria 2 use Wi-Fi to connect directly to your router.

Data automatically syncs to the Google Health app throughout the day. Each time you open the Google Health app, your device syncs automatically when it's nearby.
