Camera rep counter
Prop up your phone or laptop, pick an exercise and start. The camera counts your reps and tells you when one was too shallow. The video stays on your device.

How it works
The app finds 33 body points in each video frame with Google MediaPipe's pose model, which runs inside this browser tab. From those points it measures one joint angle per exercise — knee for squats, elbow for push-ups — and counts a rep when you go past the bottom threshold and return to the top. Nothing is recorded: frames are analysed and discarded.
- Squat counter — side-on, knee angle and depth
- Push-up counter — side-on, elbow angle and hip line
- Jumping jack counter — facing the camera
- Plank timer — the clock runs only while your body is straight
Exercise at your own risk and stop if you feel pain or dizziness. This app counts movements; it is not medical advice.
