HOW IT WORKS

TEST YOUR HAND SPEED AGAINST THE WORLD IN 20 SECONDS

01

ALLOW CAMERA

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

02

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

The legendary target is 67 waves in 20 seconds. Most people average 30–40. Can you reach the number?

05

YOUR SCORE IS AUTO-SAVED
