Wave to go
Start and finish from across the room.
How it works
Three moves, then you're jumping.
01
Prop & step back
Stand your phone up so your whole body is in frame. Any rope, or none.
02
Wave to start
Raise a hand — no touching the screen. A short countdown, then it counts every skip live.
03
Wave to finish
Raise a hand again, or tap. See your jumps, your time, and where the rope caught.
