## What is Cruxscale?

Cruxscale converts climbing grades between six roped systems (YDS, French, UIAA, British, Ewbank, Saxon) and two bouldering systems (V-Scale, Fontainebleau) instantly, fully offline, with no account required.

Beyond conversion, Cruxscale is built for route setters and climbing crews: log every route or problem you set, collect felt-grade feedback from climbers, and see a consensus grade calculated automatically from the group's input. No more guessing whether a 5.10a really climbs like a 5.10a.

FEATURES
- Instant multi-system grade conversion for routes and boulders
- Route log with crag, wall, and setter details
- Consensus grading from multiple climbers' felt grades
- Export your route log as CSV or share a grade card
- Fully offline: no account, no tracking, no network access

Whether you're cross-referencing a guidebook, setting for a gym, or gathering feedback from your crew, Cruxscale gives you a fast, honest picture of how hard a climb really is.
