Claude responded: Boulder Coach is the training companion for boulderers who want to climb smarter.Boulder Coach is the training companion for boulderers who want to climb smarter. Most climbers log sessions in their notes app, forget what they worked on, and repeat the same mistakes session after session. Boulder Coach fixes that. Log your climbs in seconds, then let Rocky — your AI climbing coach — debrief your session and help you understand what's actually holding you back. Rocky doesn't just collect data. After each session, Rocky asks you targeted questions about what stopped you, what felt strong, and where you struggled. Over time, Rocky builds a picture of your climbing and gives you something most climbers never have: an honest, data-backed read on your progress. WHAT YOU GET Log every climb in under a minute. Difficulty, grade, holds, wall angle, result, attempts — everything that matters, captured fast so you can get back to climbing. Session debrief with Rocky. When you're done for the day, Rocky analyzes your session and opens a conversation. Three focused questions. Honest feedback. A clear focus for next time. Grade progression tracking. See your average sent grade trend across your last sessions. Know whether you're improving, plateauing, or pushing into new territory. Session history. Every session saved, every climb logged. Review what you climbed, how many you sent, and where you fell. Multi-gym support. Set up your gym's grade system — Fontainebleau, V Scale, or custom — using a photo of the grade chart. Rocky reads it automatically. WHO IT'S FOR Boulder Coach is for climbers who boulder regularly and want more than just a logbook. If you're trying to break into a new grade, work through a plateau, or just climb more intentionally, Rocky is built for you. Currently in beta. We're actively building based on feedback from real climbers. Your input shapes what comes next.
