Don’t pair it from your phone’s Bluetooth screen. When syncing stops, work from the simplest fix to the most drastic: proximity and Bluetooth, then app permissions, then restarts, then unpairing and setting up again. This guide follows that order and flags where steps differ by Fitbit model and phone platform.
How do I set up my Fitbit device?
Google’s Health Help Center is explicit on one point: you can’t set up a Fitbit from your phone or tablet’s Bluetooth screen. You must open the Google Health app and follow its on-screen instructions. Menu names and layouts may change between app versions, so treat the labels below as a guide and trust what the live app shows.

- Charge the Fitbit. Connect it to its charger before you start. Google’s setup guidance lists this as the first step.
- Check your phone. Bluetooth must be on, and the phone’s operating system and the app should be up to date. Google’s requirements page lists iOS 16.4 or later and Android 11 or later. That page may be out of date, so if your phone is older, check the app store listing for the current minimum.
- Sign in with a Google Account. The requirements page says new users need one. Existing Fitbit-account users could keep signing in with their Fitbit account only until February 2, 2026, and that date has passed. If you still have a legacy Fitbit login, expect the app to ask you to move to a Google Account.
- Add the device inside the app and follow the prompts. Keep the Fitbit and phone next to each other.
Extra checks on Android
- Confirm the phone model is supported.
- Turn Power Saving Mode off during setup.
- Allow location services and the app’s location permission if setup asks for them.
If the Fitbit is already paired to another phone
A stale connection to a nearby phone or tablet can block setup. Google’s support article puts removing it after the simpler attempts, so don’t begin by deleting every paired device. Remove the old connection by following the platform-specific steps in the article.
How do Fitbit devices sync their data?
Syncing transfers the data your Fitbit has collected to your Google Health account. The connection method depends on the product, according to Google:

Syncing normally happens automatically through the day and whenever you open the app with the device nearby. To force one, open the app with the Fitbit close and use its Sync action, or pull down to refresh as the help page describes. A Fitbit can sync with only one phone or tablet at a time, which matters if two devices are signed into the same account.
Why won’t my Fitbit device sync?
Go through these in order and test a manual sync after each one. The exact menus differ between Android and iPhone/iPad, and Google publishes separate instructions for each.

- Check proximity and competition. Bring the Fitbit close to the phone and open the app. If another nearby phone or tablet on the same account is grabbing the connection, move it away or turn off its Bluetooth.
- Check Bluetooth and internet. Bluetooth must be on, and the phone needs Wi-Fi or cellular data. Toggle Bluetooth off and on to reset the connection.
- Check the app. Force-quit it and reopen it, and confirm its permissions are granted. On Android, battery or data restrictions can stop the app running in the background. Google’s Android guidance notes that background operation affects syncing, so exempt the app from those limits.
- Restart both devices. Restart the phone, then the Fitbit, and sync manually. Restart methods differ by Fitbit model, so use Google’s model-specific restart instructions rather than a generic button combination.
- Remove and re-pair. Remove the Fitbit from the app, then forget it in the phone’s Bluetooth settings, then set it up again from the app. A leftover operating-system Bluetooth pairing can interfere with re-pairing.
- Reinstall the app, but only last. Before uninstalling, confirm your phone’s operating system is still supported. An older phone may not be able to reinstall the app.
- Contact support. If nothing works, contact Google/Fitbit Customer Support and tell them your phone platform and exact Fitbit model.
When the problem is charging
A device that won’t charge can look like a setup failure. Google’s charging troubleshooting page gives different procedures by device family, with separate examples for Charge 5, Charge 6 and Luxe trackers and for Sense and Versa watches. Common checks include:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Cleaning dirty or stuck charging pins.
- Making sure the charger seats correctly on the device.
- Trying a different power source.
Charging cables are model-specific, so check compatibility against your exact Fitbit before buying one. A replacement or spare only makes sense if your original is missing or faulty.

If you use third-party apps with Fitbit data
Google’s third-party connection page says Fitbit Web APIs will stop being supported from October 30, 2026. Partner apps that connect this way need to be reconnected through the partner app before then. Google says connections made through Health Connect or Apple Health are not affected. With the deadline weeks away, check the current wording on that page and reconnect any affected app now.
