Push-Up Counter

What it measures

You do push-ups in front of the camera (side angle). The app tracks your shoulder-to-floor distance every frame, counting a valid rep only when your chest reaches the bottom and your arms fully extend at the top. Half-reps and partials don't count.

Why it matters

Push-ups are one of the few upper-body endurance tests that translate directly to functional strength. Military, police, and most sport teams still use them as standards. The catch is that gym push-ups get sloppier as you fatigue — the rep count stays the same but the actual work drops. Auto-counting honest reps tells you the truth.

How to do it

1. 1Set your phone 2 meters to your side, lens at shoulder height.
2. 2Get into push-up position. The app verifies it can see your shoulders, hips, and elbows.
3. 3Start when you hear the beep. Go to your normal full range.
4. 4The voice calls every valid rep number. Half-reps are skipped silently.
5. 5When you fail or stop, the app shows total valid reps + any flagged-form ones.
