## What is Catchline?

One cue for your snatch, clean or jerk, and the measurement behind it. Analysed on your iPhone: your video never leaves it, no signal needed, never used to train AI.

Film a side-on rep. Get the one thing to fix, the reason for it, and later, whether it stuck.

Most form checks hand you five faults and three opinions. Catchline gives you one cue per set: the earliest fault in the chain, which is usually the one causing the others. Fix that first.

WHAT IT WORKS ON
Snatch, clean and jerk. Kipping pull-up and bar muscle-up.

HOW IT WORKS
1. Prop your phone side-on, about 3 m away, with the whole bar (or rig) in frame. Film 1 to 5 reps.
2. Catchline finds your key positions on your iPhone and stacks them into one frame, with the bar or hip path drawn through them.
3. You get one cue, the measurement behind it ("bar drifted 6 cm away at the hip"), and the frame where it happened.
4. Next session, film again. On Pull, Catchline checks the same number and tells you if the cue is working, still trying, or didn't stick.

WHY YOU CAN TRUST IT, AND WHERE YOU SHOULDN'T
Computer vision measures your positions from the video, on your iPhone. Rules written by weightlifting and gymnastics coaches decide which fault matters most. The cue is worded from those rules, not by a chatbot. Every cue is labeled "AI estimate", because the measurement behind it is one.
If the angle is wrong, the bar is hidden, or two reps disagree, Catchline says so and asks you to film again. It would rather tell you it can't see than guess.
Catchline is a coaching aid, not a medical tool. If something hurts, see a professional.

PRIVACY
When you are online, Catchline syncs a small record per lift (movement, load, whether it was made, which cue) so your cue history follows you to a new phone. No face tracking. No ads, no tracking. Delete everything from the You tab whenever you like.

## Version history (last 4 releases)

### 3.1 — 2026-10-23

Catchline now analyses your lift entirely on your iPhone. Your video never leaves your phone, and it works with no signal. Your first 3 videos are still free.

### 3.0 — 2026-10-18

Parallax is now Catchline, a form check for weightlifting and CrossFit gymnastics. Film a side-on snatch, clean, jerk, kipping pull-up, bar muscle-up or kipping handstand push-up and get one cue to work on, with the measurement behind it. Your first 3 videos are free. If you bought Parallax lifetime, you get Catchline Founding membership (Pull for life) at no cost: tap Restore Purchases on the Plans screen. Questions: pirsquare.yash+catchline@gmail.com.

### 2.0.0 — 2026-09-08

Parallax is rebuilt around the thing couples actually needed it for.

The daily question game is gone. Now, when something's up, each of you privately says your side and you both get one calm middle ground, never each other's raw words.

New: a heat check that makes you cool down before writing mid-fight, a 30 second daily pulse with no typing, and Memory, your record of what you came through and what worked.

### 1.0 — 2026-07-14

No release notes.
