Band resistance ↓
The band carries what you cannot carry yet. Progress here is not more reps, it is the same reps on a thinner band.
Your pocket counts.You just pull.
Phone in your pocket, walk to the bar and pull. Every rep is counted from the motion of your own body and spoken out loud as it lands.

You are the weakest part of your own log.
Pull-ups are the one lift where you cannot hold a phone, cannot press a button and cannot look down without losing the rep.
So you count in your head. Somewhere past six the count goes soft, and by the third set you are guessing. Then you drop off the bar and the number has to survive the walk home, which it rarely does. What you are left with is a notes file that says “3x5 green band” and cannot tell you whether that was progress.
The training was never the problem. The bookkeeping was.
The phone stays in your pocket the whole time.
A pull-up is a measurement, not a guess. Your phone always had the sensors to read it. It has just never been asked to.
When you pull, your entire torso travels up and back down through the same narrow arc. The phone against your hip rides that arc exactly: a rise, a hold at the top, a controlled fall.
That shape looks nothing like walking or fidgeting, so each completed arc increments the count and is read aloud as it lands. Half reps do not qualify. Kipping does not qualify.
The only part you do is the pulling.

Three levels, one log
Most trackers only count reps, so band work looks like standing still and weighted work looks like going backwards. Pull Up School knows what you are on today and moves the number that is actually moving.
No band
Bodyweight
Reps ↑
Just you and the bar. From the first single to a clean set of five, every rep is its own line.

Bodyweight is the baseline now. The belt goes on and the number that climbs is kilos.
Fair questions, asked bluntly.
Can a phone in a pocket really count a pull-up?
It is not watching you. It is feeling you. A pull-up moves your whole torso through a tight, repeatable arc, and your hip carries that arc cleanly. That signature is far easier to read than a step or a swim stroke, and both of those have been solved for a decade.
Does it track other exercises too?
No, Pull Up School only counts pull-ups. Every exercise has its own motion signature, so each one needs its own detector, built and trained from scratch. I would rather get one movement genuinely right than five of them roughly.
Why not just use a notes app?
A notes app cannot measure your movement, so it cannot count a real rep. It only keeps the number you type in afterwards, and it never shows you anything back. Pull Up School measures the movement itself, so what you are left with is real data about your own training, and the insights drawn from it get deeper as the app grows.
Where does my training data go?
There is no account to make and no email address to hand over. What does leave the phone is the raw motion behind a rep, sent under an anonymous Tester ID so the counting keeps getting better for everyone. The privacy policy spells out exactly what that is.
Do I need specific hardware?
No wearable, no strap, no watch: the phone in your pocket is the whole sensor. The beta runs on iOS for now, and an Android app is on the roadmap shortly after it.
Which pocket works best?
A trouser pocket, held against your hip or thigh. Jeans, shorts and joggers all read well. A hoodie pocket does not, because the phone swings free of your body, and a very loose trouser pocket costs you accuracy for the same reason.
Where it stands today
The first build goes out to thirty testers. The reps beside it are ones the app detected from motion on its own, not reps somebody typed in afterwards.
23 seats left in the first build.
Detected across 3 logged sets.
