42 Laps: Auto Lap Counter

MB Apps Co.

About this app

42 Laps turns your phone into a hands-free lap counter for solo pool practice. Prop it at the end of your lane, mark the wall zone, and it automatically counts your lengths and times your splits by watching for the motion of a touch — no smartwatch, no whiteboard, no counting in your head.

How it works Point your phone's camera at the wall or turn spot. Drag a zone onto the exact touch point and 42 Laps watches for motion there in real time — a touch in, then out, logs a length and starts timing the next one.

Features

Automatic lap counting and per-length split times
Optional goal pace with live ahead/behind-pace feedback on every length
Session history, saved locally, with one-tap sharing of your splits
Trends across sessions, so you can see your pace improving over time
Simple setup: pick a zone size and sensitivity, test it, and go — exact manual controls are in the same settings sheet if you want them, but not required
Privacy Everything happens on your device. Camera frames are analyzed live and never saved or uploaded. Your session history stays on your phone unless you choose to share it.

No account. No ads. No tracking.
