Crux & Chalk

Crux & Chalk is a focused, offline climbing companion for boulderers who want every session to have a purpose. Keep a personal route board, record attempts, mark sends, and open each project for practical beta notes. Build strength with a compact four-block training plan, check off each exercise, and reset the workout whenever you begin a new cycle. Your logbook turns route activity into an immediate session summary, while Progress shows completion rate, attempts, sends, and training consistency. Thoughtful starter projects make the app useful from the first launch, and every route you add stays on your device. Use Crux & Chalk at the gym or crag without an account or connection. Your climbing projects, workout state, and progress are stored locally for fast, private access.
