HOW TO PLAY

• Place the phone 1.5–3m away with a plain background behind you.
• Tap START, hold still for 2s while the app calibrates the background.
• Juggle. Each direction reversal of the ball is counted as a touch.
• If detection is jumpy, lower SENSITIVITY. If it misses, raise it.
• Increase MIN RADIUS if hands trigger false counts.
• RESET clears the count and re-calibrates the background.
• Best score is saved on this device. Camera frames stay on-device.
