How to Get Help

Email 869501402@qq.com for app support. Include your app version, iPhone model, iOS version, Bluetooth device name, and screenshots if possible.

Bluetooth Device Connection

Hit the device once to wake Bluetooth, then open app settings and scan for a device whose name starts with SENBALL# and ends with a digit. After the first successful connection, the app automatically reconnects to the last device on later launches.

Local Profile and Cloud Sync

The app does not require registration, login, or an activation code. It automatically creates a local user profile on first launch so training records and optional cloud features can work.

Before training scores are uploaded to cloud sync or global leaderboards, the app asks for consent. Users can decline and continue local training.
