Make every jump count
Use a steady camera and good light. Stand back with one person’s shoulders, hips and feet visible. Hold still during the countdown, then jump naturally. If tracking is lost, your session pauses—step back into view and press Start.
This is a bounce-based practice counter. Camera movement, squats, tiny jumps and alternating-foot steps can affect accuracy. Keep this page open while jumping; switching apps pauses the session.
If the camera is blocked, allow camera access in your browser’s site settings and try again. Phones need the secure HTTPS site. The first start downloads the pose model, so keep your internet connection on.
