Secure your phone upright, face the camera and keep your head and ankles visible with room to jump. Stay in view for one second. The green border fills, followed by your selected countdown (3, 5 or 10 seconds). Once the countdown starts, temporary pose loss does not restart it.

Use good front lighting and a simple background. Keep the phone stable and your whole body in view. The app supports basic two-foot jumps and detects jumping motions, not rope passes. Different movements and devices can affect accuracy. A spoken tracking-loss reminder follows sustained loss when voice reminders are enabled.

Check media volume and any connected headphones or speakers. In Settings, choose a count sound and configure music and voice reminders. The starting countdown always speaks; the final ten-second reminder is spoken once when workout reminders are on.

Recording starts with the workout when Record workout video is enabled. Replay from History or save a copy to Photos. Turning recording off preserves workout counts and existing videos. Local storage shown in Settings excludes Photos copies.

Read the warning shown during the workout or on the result page. Counting can continue if recording fails. Free storage by deleting unneeded videos, reopen the app and retry a short workout. A silent video may be kept if audio export fails. Force-closing the app while saving can leave an incomplete video.

Swipe left on a workout in History to delete it and its local video. In Settings → Help, open How to use or choose Reset and show tutorial. Photos copies are not deleted with workout history.

A physical iPhone or iPad with iOS 17 or later and a usable camera. English is the fallback language; Simplified and Traditional Chinese are also supported.
