AI Rep Counter
Prop up your phone, step back, and work out. The camera watches your form and counts every rep out loud — hands-free, no tapping mid-set.
Free demo: 3 sessions a day, 2 minutes each. Pro unlocks extended sessions — up to 60 minutes of continuous counting.

- Prop your device — lean your phone against a wall or water bottle, roughly waist height (on the floor for push-ups).
- Step back about 6 feet. For squats, head-to-knees in frame is enough (feet can be cut off — we track hip depth). Jumping jacks need your whole body. The counter tells you what it needs to see, and shows the live joint angle it's measuring.
- Light yourself, not the camera — face a window or lamp; avoid strong light behind you.
- Keep the screen on and the tab in front. We keep your screen awake during a session, but if you switch apps or lock the phone, the camera pauses (a browser privacy rule) and the session resumes when you return.
- Listen for the count — each rep is announced out loud so you never have to look at the screen.
Pick your exercise
Stand 6–8 ft back, facing the camera, whole body in frame.
FAQ
How does the AI rep counter work?
It uses on-device pose estimation: your camera feed is analyzed in your browser to track 33 body landmarks, and a rep is counted each time you complete a full movement (for example, squatting down and standing back up). Nothing is uploaded — the video never leaves your device.
Is my camera video uploaded or recorded?
No. All processing happens locally in your browser. The video is never sent to our servers, never recorded, and never stored. Close the tab and it is gone.
Which exercises does it count?
Squats, push-ups, jumping jacks, and bicep curls at launch. These have clear movement signatures the camera can read reliably. More exercises are on the way.
Why did counting stop when I switched apps?
Browsers pause the camera when a tab goes to the background or the screen locks — this is a platform privacy rule, not a bug. The counter keeps your screen awake during a session and pauses gracefully if you switch away, resuming when you come back.
What do I get with Pro?
The free demo gives you a few short sessions a day. Pro unlocks extended sessions — up to an hour of continuous counting at a time — so it covers a full workout.
