What is the Camera Lunge Counter?
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'.

Questions people ask
Does it count each leg?
Every lunge is one rep, left or right.
Does it work from any camera angle?
The view does not matter much, because the angles are 3D. It looks for the "Standing" position, then the "Down" position. Stand 2 to 3 metres from the camera, full body in view.
Is my video uploaded or saved?
No video leaves your device. Counts lunges with the camera and checks your front knee; the detection runs locally, and nothing is recorded, uploaded or stored and the camera stops when you finish. Stand 2 to 3 metres from the camera, full body in view.
What do I need?
Open the page over https in Chrome, Edge, Safari or Firefox and allow the camera. Stand 2 to 3 metres from the camera, full body in view. Stand tall to start. A rep counts when your front knee bends to about 90 degrees and you return to standing.
Can I use a video instead of the live camera?
Yes: choose 'Analyze a video file', select your clip, and the same counting rules apply as live. Counts lunges with the camera and checks your front knee. Stand tall to start. A rep counts when your front knee bends to about 90 degrees and you return to standing.
