HOW IT WORKS

01
ALLOW CAMERA
Grant camera permission when prompted. Your camera stays on-device — nothing is recorded or uploaded.

POSITION YOUR HAND
Hold your hand in front of the camera inside the wave zone circle. Keep your background still for best detection.
03
WAVE AS FAST AS YOU CAN
Move your hand back and forth rapidly. Each detected wave counts as one rep. Standard mode is 20 seconds — unlock 40s & 60s with VIP.
04
HIT 67

05
