A logbook for gym boulders.
For regular indoor boulderers, on iOS 26. Boulderers log between goes with chalk on their hands, and a tick list says nothing about progress on a project. Highpoint draws every problem as a chart of its holds and records the highest move reached.
Every problem drawn as a chart of its holds.
Holds are stars, moves are lines. Bigger holds are bigger stars; the line stops where your best go stopped.
Your highpoint glows. Move 7 of 9 after 11 goes; when you send, the whole chart lights up.
Made for chalky hands. The counter sits in the thumb zone and a send is confirmed by holding.
A wall drawn as a night sky.
Technor, set light, for grades and large numbers, with Satoshi for the rest; the chart lights up when you send. iOS 26. A clickable prototype in HTML; the film above is recorded from it.
The gym data is a sample.
