Camera Jumping Jack Counter (AI)
Jumping jacks are fast and easy to lose count of. Face your camera, step back until your whole body is visible and start: a rep counts when your arms go overhead and your feet jump wide, then return to hands down and feet together.
It works at any angle and gives a spoken count, so you can focus on the cardio. Set a goal such as 50 or 100 and the coach calls it when you reach it.

Frequently asked questions
Why did a jack not count?
Both conditions are needed in the same rep: arms above the head and feet clearly wider than your shoulders.
Does it work from any camera angle?
Yes. The tool measures your joints in 3D, so front, side and diagonal views all give the same angles. Keep the phone or laptop upright (not tilted on its side) and keep your whole body in the picture.
Is my video uploaded or saved?
No. The pose detection runs inside your browser on your own device. Nothing is recorded, uploaded or stored, and the camera stops when you finish.
What do I need?
Any phone, tablet or computer with a camera and a modern browser (Chrome, Edge, Safari, Firefox). The page must be opened over https for the camera to work.
Can I use a video instead of the live camera?
Yes. Press 'Analyze a video file' and pick a recorded workout; it is counted the same way.
The counter is not counting. What should I check?
Make sure your whole body is visible, the room is lit, and you start from the correct start position. The message under the picture tells you what the camera is missing.
