Stone Friend

Stone Friend is a companion app for rock climbers that records every attempt, organizes routes, and provides clear performance metrics so you can train more effectively. It captures video of your climbs with variable-speed playback and basic editing tools, keeps a searchable log of routes by gym, rating and hold color, and generates charts that show flash rate, average attempts and personal bests.
