Push-Up Counter for iPhone
Prop your iPhone against something at floor level, get into position, and start doing push-ups — Wolkup counts every rep for you, live, without touching the screen.
How it works
Wolkup uses your iPhone's camera and on-device pose recognition to follow your body through each rep. It tracks the angle of your arms as you go down and back up, and only counts a rep once you've completed a full range of motion — not a half-hearted bob near the top. A small orientation check filters out obvious false positives, like standing up and waving your arms in front of the camera.
Everything runs locally on your phone. No video is recorded, saved, or sent anywhere — the camera feed exists only for the seconds it takes to detect your position.
Why it's useful
Counting your own push-ups gets unreliable past rep 15 — you lose count, you round up, or you stop early because you're not sure how many you've actually done. A camera counter removes that friction entirely: you just move, and the number takes care of itself.
Wolkup also turns each session into something bigger than a single set. You can train freely and let sets split automatically on a rest pause, or set a goal — a target rep count, or a number of sets like 3×10 — and see progress toward it as you go. Every push-up workout feeds your Upper Body strength stat and your streak, so counted reps actually add up to something over time instead of disappearing into a log nobody reads.
Limitations — worth knowing before you start
This is a rep counter, not a form coach. Wolkup can tell whether you completed a rep's range of motion, but it isn't a substitute for a trainer checking your elbow angle, back alignment, or breathing. If your form is off in a way that doesn't affect the tracked range of motion, the app won't catch it.
It also needs to actually see you: the phone has to be positioned so your arms and torso stay in frame through the full movement. Very dim rooms or a camera angle that clips your arms mid-rep can cause missed or extra counts. And right now, camera tracking covers push-ups, squats, and plank — not every possible bodyweight exercise.
