Ace setup & troubleshooting
Use this Ace-specific guide for setup, connection, syncing, charging and common troubleshooting questions.
1. Set up your Ace
Install the Fitbit app, sign in, turn on Bluetooth, and follow the in-app steps to add Ace. If this is a kids device, use the parent or guardian account flow shown in the Fitbit app and follow the child-account prompts.
2. If it will not connect
Keep the device close to your phone, confirm Bluetooth is on, check app permissions, and restart the phone and device before trying again.
3. If syncing is not working
Open the Fitbit app and try a manual sync. Check Bluetooth, internet access and available app or device updates.
4. Charging help
Use the charging accessory designed for this model and make sure the charging contacts are aligned. If the model uses a replaceable battery, use the correct battery type instead.
5. Notifications and account access
Check phone notification permissions and app settings. For account problems, use official account recovery options. Never share passwords or verification codes with someone who contacts you.
