What is the Camera Sit-Up & Crunch Counter?
Lie on a mat with your knees bent and let the camera see your shoulders, hips and knees. The counter learns what 'lying down' looks like for you in the first second, then counts a rep every time your torso rises far enough and returns to the floor. Choose full sit-ups or smaller crunches.
Because it calibrates itself to your own lying position and uses 3D body angles, it works from a camera at your side, at your feet or at a diagonal. Voice counts and a goal call keep you focused on your abs, not on counting.

Questions people ask
What is the difference between sit-up and crunch mode?
Sit-ups need your torso to rise about 42 degrees from your lying angle, crunches about 17 degrees.
Does it work from any camera angle?
The view does not matter much, because the angles are 3D. It looks for the "Lying" position, then the "Up" position. Lie on a mat with your knees bent and the camera 2 metres away so it sees shoulders, hips and knees.
Is my video uploaded or saved?
No video leaves your device. Counts sit-ups or crunches with your camera, from any angle; the detection runs locally, and nothing is recorded, uploaded or stored and the camera stops when you finish. Lie on a mat with your knees bent and the camera 2 metres away so it sees shoulders, hips and knees.
