Count clean reps. Hold a straight plank.
Push-up and Plank Coach watches your push-ups and planks through your camera and checks them against clear rules. A push-up counts only when your chest reaches the down line AND your arms lock out at the top. Half reps do not count, and every miss gets one named hint: go lower, lock out, hips sagging, hips piked. Plank mode banks good-form seconds only: the clock pauses whenever your line breaks.

Start position: not set yet. Set it in a lesson before your first set.
Camera setup: put the camera to your SIDE, about 2 metres away, so it sees your whole body from head to heels. Clear the floor space around you. Good light helps. The camera turns off when you leave the lesson.

How a rep is judged
- Down: your shoulders drop at least 35% of your torso length, and your elbows bend to 140 degrees or less.
- Up: your shoulders come back within 12% of the start height, and your elbows open to 160 degrees or more (full lockout).
- Straight line: your hips stay within 10% of body length of the shoulder-to-ankle line. Below the line is sagging, above it is piked.
- Head: your nose stays within 18% of torso length below your shoulders. Lower than that is a dropped head.
- A rep counts only on a complete down-then-up cycle. A shallow rep or a rep without lockout is rejected with the named hint, and a rep with any form fault in it counts but is not clean.
