## What is Cruxbook?

Every gym. Every colour. Two taps.

Set up your gyms with their colours in under a minute. At the wall: tap the colour, then attempt or top. Cruxbook works out flashes, projects and stats. Your phone is enough.

HOW IT WORKS
• Add the gym: name it, tap the colours from easy to hard, done. Grades only if you want them.
• Colour, then attempt 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
Colour circuits, tape at the start or the gym's own numbers. Switch gyms and they sit side by side in your logbook, each in its own system. Cruxbook only compares them once you map grades. It never guesses.

FREE, FOREVER
Unlimited sessions, gyms and colour systems. Attempt, flash, top, projects. Stats for the last 30 days. CSV export and delete.

PREMIUM
Season stats and grade curve, project history across sessions, gym comparison via Font grades and a review when the gym resets a circuit.
Premium is an auto-renewing subscription, billed monthly or yearly to your Apple Account. It renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.

Your logbook is seen by your account only. Export and delete any time, Premium or not.
