Don’t start by pairing the tracker in the phone’s Bluetooth menu; Fitbit setup runs through the app. Charge the device first and keep it close to your phone during setup and syncing.
Before you connect your Fitbit
- Check phone compatibility: Google lists iOS 16.4 or later and Android 11 or later among the Fitbit setup requirements. Requirements can change, so check Google’s current Fitbit setup requirements for your phone and device.
- Confirm account access: New users need a Google Account. Existing Fitbit-account users could use that account until February 2, 2026; Google says Google Account sign-in is required after that date. See the same setup requirements for current account details.
- Charge the Fitbit: Connect it to its charger before setup, as directed in Google’s Fitbit setup guidance.
- Enable Bluetooth: Make sure Bluetooth is on in your phone’s settings. Keep the Fitbit near the phone while pairing and syncing; Google’s guidance says, “Your Fitbit device must remain near your phone to sync.”
Connect the Fitbit in the app
- Install or open the Fitbit app on a compatible phone and sign in with the required account.
- Turn on Bluetooth in the phone’s settings.
- In the Fitbit app, start the device setup flow and choose your Fitbit when prompted. Follow the on-screen instructions.
- Keep the Fitbit close to the phone and follow any prompts shown on either device until setup finishes.
Do not pair the Fitbit first through the phone’s general Bluetooth screen. Fitbit directs users to complete setup through its app, not the phone or tablet Bluetooth menu. The official help result describing this distinction is available in Romanian; the procedure above summarizes it rather than presenting a translated sentence as an English quotation.

2. Reopen the app, then restart both devices
Close and reopen the Fitbit app. If the connection still fails, restart the phone and Fitbit, then retry in the app. Restart procedures differ by Fitbit model; use the instructions for your exact device rather than relying on a generic button combination. Google’s Fitbit syncing guidance for Android and device troubleshooting guidance cover these steps.
3. Check for another nearby phone or tablet
If another phone or tablet signed in to your account also has the Fitbit app, the Fitbit may be trying to connect through a different host. Check nearby devices and remove competing app/device connections as directed in Google’s Android sync troubleshooting.

4. Clear the old pairing and set up again
Use this step only after the simpler checks fail. Remove the Fitbit from the Fitbit app, then open the phone’s Bluetooth settings and forget or unpair the Fitbit there. Reopen the Fitbit app and run setup again from its prompts. Google warns that an old device profile can interfere with re-pairing; see Fitbit’s updating and connection troubleshooting.
5. Reserve a factory reset for a last resort
Do not factory-reset the Fitbit just because it is not syncing. Google’s advanced troubleshooting treats a reset as a last resort for an unresponsive or persistently failing device. A reset can erase data and settings stored locally, including unsynced activity, alarms, goals, and notification settings. Follow the reset instructions for your specific model only when less disruptive fixes have failed.

When charging is the obstacle
A Fitbit that cannot be charged may need a working, model-compatible cable before setup can begin. Check the exact device model and connector fit before buying a replacement. A charging cable is not a Bluetooth accessory and is unnecessary if your Fitbit is already charged.
