On-device inferenceno network in the counting loop
Work out mindlessly,
we keep your counts
Real-time movement detection through your browser webcam. No wearables, no video uploads, no friction — automatic rep counting and tempo for every set in your home routine.
No sign up required for the demo. Nothing uploaded to servers, ever.
How it works
Queue it, prop it, forget it.

Rep counter and cadence
Every rep is called out loud, and so is the end of a set. You always know where you are without checking.
