Push-OffProp your phone on the floor, face the camera, and go. The camera judges every push-up — depth, lockout, hips, knees — and refuses to count the ones you cheated.

Four checks before the clock starts: full body, facing the camera, start position, lighting.
“Go lower”, “Lock out”, “Keep your hips down” — called out as you move.
Personal bests, head-to-head results and a global valid-rep leaderboard.
