Quick start

  1. Open the app.
  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. Tap End when you're done. 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 free trial can be canceled before it ends with no charge.
Does it work without a rope?Jump rope is what it's built and tuned for. It counts landings rather than rope passes, so ropeless moves — jump-in-place, high knees, tuck jumps — often register too. They aren't tuned yet, though, and a long set can end early. Proper ropeless support is in progress.
