Cruxbook: Bouldering Log

Cruxbook is the bouldering logbook for every gym. Set up your gyms with their colours in under a minute. At the wall: tap the colour, then try or top. Cruxbook works out flashes, projects and stats.

HOW IT WORKS
- Add the gym: name, tap the colours from easy to hard, done. Grades only if you want them
- Colour, then try or top: two taps per boulder, chalky fingers welcome. Cruxbook spots the flash itself
- See what grows: volume, flash rate and pyramid per gym, projects across sessions

YOUR GYM TOO, NO PARTNER DEAL NEEDED
Colour circuits, tape at the start or numbered scales: every gym keeps its own system. Cruxbook only compares gyms once you map grades. It never guesses.
