Quick start

  1. Open the app and sign in.
  2. Prop your phone up and step back so your whole body is in frame.
  3. Wave a hand to start (or tap Start). Jump.
  4. Wave a hand to finish (or tap End). See your jumps, time, and catches.

Common questions

The count isn't accurate.Make sure your whole body is in frame and the area is reasonably lit. The camera reads your movement, so a clear view of your torso and legs matters most.
It didn't see my hand wave.Raise a hand to about shoulder height and hold it there for a moment — you'll see "Hold it there…" when it's registering.
How do I cancel my subscription?Manage or cancel anytime in your Apple account: Settings → your name → Subscriptions. The 3-day free trial can be canceled before it ends with no charge.
Does it work without a rope?Yes — it counts vertical jumps, so straight jumps and high knees work too.
