RepCounter AI: count your reps from a video

Record a set with your phone or upload a clip, and RepCounter AI counts your reps in the browser using pose tracking. It works for dumbbell curls (each arm counted separately), squats, lateral raises, pull-ups and lat pulldowns. Squats that could go deeper are flagged, and you confirm the count before saving.

It is free, needs no account and nothing to install. Your video never leaves your device: only a short set summary (exercise, weight, reps) is saved, in your browser. Each saved set gives you a next-set target with double progression.
