Camera off. Nothing is uploaded; detection runs in your browser.
How to play
- Put the camera so your whole body — head to shoes — stays in frame, roughly 2–3 metres away.
- Stand ready in your start position and press START — nothing is measured before that.
- Every attempt starts with a 3 · 2 · 1 countdown — stand still until it says JUMP!
- Jump straight up on JUMP! and land on the same spot; only then is the flight measured.
- In Auto detect it names the style itself: normal, paused squat, arm swing or single leg left / right.
- Height comes from your flight time, so land on the balls of your feet, not in a deep crouch.
- Your best jump is kept as a personal best on this device.
What you train
A measuring instrument rather than a game. The camera only has to see when your feet leave the floor and when they land: the jump height follows from your flight time with the standard ballistic formula, the same principle a contact mat uses. Choose a countermovement jump, a strict squat jump with a held pause, or five reactive jumps that also report ground contact time and your reactive strength index. Your best jump is kept as a personal best on this device.
