About
Callus is a climbing training log for climbers who train with intention. Log hangboard work, pull strength, sends and attempts, and project sessions — then read your season on a map-inspired dashboard.
LOG WHAT MATTERS
• Hangboard — edge depth, load, sets, hang time, and session quality
• Pull strength — weighted work and bodyweight reps with automatic % bodyweight
• Climbing — grades, sends, attempts, session counts, and optional project links
• Notes and custom entries for mobility, rehab, or anything else in your plan
SEE YOUR TRAINING
• Home — PRs, latest send, training mix, and recent volume
• Stats — hangboard peaks by edge and pull strength summaries
• Charts — grade progression and session trends over time
• Path — goal-grade benchmarks, weakness radar, and waypoints
• Projects — linked sessions with automatic send detection
CLIMB WITH YOUR CREW (optional)
• Find real climbing gyms and crags near you on a map styled like a topo sheet
• Plant a flag to show your crew where you're headed — and see who else is out
• A shared calendar of check-ins, plus crew and per-gym session chat
• Private by design — only your crew sees your flags. Create or join a crew with a code or QR, and leave anytime
