Camera Lunge Counter (AI)
Stand where the camera can see you from head to feet and start lunging. The counter looks for a wide stance and a front knee bent to about 90 degrees, then counts when you return to standing. Reverse, forward and stationary lunges all work, left or right leg.
Measured in 3D, so front, side or diagonal camera positions are fine. Short, shallow steps prompt 'Step longer and sink lower'.

Frequently asked questions
Does it count each leg?
Every lunge is one rep, left or right.
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.
