Hidden Lines: Climbing

That moment on outdoor rock where you don't know if the problem goes. Where the beta isn't obvious and you aren't sure which foot to use. Hidden Lines brings that puzzle to your home wall. AI detects the holds. You choose the difficulty. The app generates a problem. And from there, it's on you.

HOW IT WORKS

1. Select a photo Take a photo or choose an existing one of your home wall — woody, training board, spray wall, anything with holds.

2. Set up your wall AI detects the holds. You label them crimp, sloper, etc. You set the sit start reach and wall dimensions.

3. Generate and climb Pick a difficulty, choose which hold types to favour or avoid, toggle campus mode (or not). Then tap the sparkles to generate a problem.
