About

RepDetect counts reps using in-browser pose estimation. No videos are uploaded.

What it does

You pick an exercise, optionally calibrate in Settings for tighter tracking, and RepDetect counts clean reps while showing live form cues.

What it doesn’t do

It doesn’t record or upload your video. It’s a lightweight tool for practice and consistency, not a medical or coaching device.

Tips for accuracy

Keep your full body visible, especially ankles for jumping jacks and knees for squats/lunges.

Use good lighting and keep the camera stable.

Move with control. Very fast movements can be ignored as noise.

How it Works (Privacy Built-in)

RepDetect is 100% private. We understand that having a camera active can be intimidating, so we built this application to run entirely inside your browser. No video frames, images, or pose coordinates ever leave your device.

Zero Server Uploads: When you grant camera access, the video feed is routed strictly to a local HTML <canvas> element on your screen.
Google MediaPipe Vision: We use an advanced AI Vision model that is downloaded directly into your browser's memory (via WebAssembly).
Coordinates Only: The AI mathematically scans the video locally to find 33 coordinates (your joints, eyes, and shoulders). It discards the video frame immediately and only uses those X, Y, Z numbers to calculate the "angle" of your reps.
Local Storage: Your workout history and settings are saved securely on your own hard drive using standard web localStorage.
