Crux Logs: Climbing Journal

Crux Logs is a private climbing journal and tracker for sport, trad, top rope, and bouldering. Log sessions, route attempts, sends, falls, fear ratings, project notes, and grade progress without an account.

Most climbing apps stop at sends. Crux Logs asks the harder question: are you getting braver?

LOG CLIMBS FAST
Grade, outcome, attempts, falls, hangs, flash, fear, notes, done. Use it from iPhone or Apple Watch while you climb.

PROJECTS
Track a route or problem across multiple sessions. Keep attempts, beta notes, media references, and the full path from first try to send in one place.

GRIT ENGINE
Six deterministic metrics computed from your log. No AI, no guessing, no generic coaching.

- Push Rate: how often you try hard things
- Fall Willingness: how often you practice falling
- Fear Tracking: whether exposure is making climbs feel calmer
- Comfort Zone Ratio: how much volume sits below your limit
- Project Persistence: how long you stay with hard routes
- Session Consistency: how steady your climbing rhythm is

GRADE PYRAMID
See volume and sends by grade. Split your progress by routes, boulders, indoor sessions, outdoor sessions, and time window.

ROUTE DATABASE
Browse routes from OpenBeta, save local crags, use GPS to detect nearby areas, and link ticks to real routes.
