Chalk is the climbing app built for climbers who care about progression. Whether you're projecting your first V5, ticking sport routes across Europe, or tracking sessions at your local gym - Chalk gives you the tools to climb better and explore further.

DISCOVER ROUTES WORLDWIDE

TRACK EVERY SESSION
Log climbs with grades, outcomes, and photos. Chalk supports 13 international grading systems with automatic conversion - from Font to V-grade, YDS to UIAA - so your logbook works wherever you climb. Tag your sends, flashes, attempts, and projects, then review detailed session summaries.
