Why Crux
✗ App fragmentation
✓ One app for your whole climbing life — gym, outdoor, training board.
✗ No social layer
✓ See every send, like, and project from your climbing crew.
✗ Gyms not in any app
✓ Add any gym yourself. No B2B deal required. Community-driven, always.
Features
Built for the indoor bouldering boom. Works for outdoor crushers too.
Log every climb — V-scale, Font, or YDS. Indoor gym or outdoor crag. Track your grade pyramid, session history, streaks, and personal bests in one place.
See what your friends are projecting, flashing, and sending. Like their sends, drop a comment, and stay connected with your climbing crew — Strava-style but for climbing.
Every gym in your city, added by the community. Browse fresh routes in your grade range. See what was just set, what's about to be stripped, and plan your session before you leave the house.
Find climbing partners at your home gym. Filter by grade range, schedule, and discipline. Post a session time and see who else is going. No more climbing solo.
Get Started
Set your grade range, home gym, and disciplines. Takes 60 seconds.
Add a gym if it's missing, pick a route, and log your send. Your logbook starts building immediately.
Follow friends, discover partners at your gym, and share your sends to the feed.
Free to download. No gym partnership required. Just you and your sends.
