How do I connect a heart rate monitor?: CornerMan works with any standard Bluetooth heart rate monitor (chest strap or armband). Turn the monitor on, open the app, and it will discover and connect automatically. You can also use your Apple Watch to read heart rate directly — no external monitor required.
Do I need an account or internet connection?: No. CornerMan requires no account and works fully offline. Your training data stays on your device and in Apple Health.
Where are my workouts saved?: Every completed session is stored on your device and written to Apple Health as a Boxing workout, including heart rate samples and active energy burned.
The voice coach isn't speaking. What should I check?: Make sure your device isn't in silent mode with speech muted, that the app's volume is up, and that the callout interval isn't set too long. The coach lowers your music while it speaks and restores it afterward.
How is my privacy handled?: See our Privacy Policy. In short: your workout and health data never leaves your device except through Apple Health.
