Stone Friend

Stone Friend is a climbing companion app that helps boulderers and route climbers record attempts, analyze performance, and maintain a tidy climbing log. Place your phone, tap record, and capture each attempt with adjustable playback speeds, simple editing tools, and the option to mark your best climbs for later review. The app organizes routes by gym, rating, or hold color, tracks metrics such as flash rate and average attempts, and supports virtual competitions with leaderboards and real prizes to help climbers improve and share progress.

Key Features

Stone Friend records climbs with 0.5x–2.0x playback speed, includes in-app video trimming and basic editing, and lets you tag and save standout ascents for later review. You can search and organize routes by gym, rating, and hold color, save routes, and browse a searchable history of attempts. The app tracks progress metrics like flash rate, average attempts, rating distribution, and personal bests with customizable timeframes. Virtual competitions award points for flash rate and rank participants on leaderboards, and videos can be exported to your device album, shared to social apps, or watermarked to protect content. Multi-gym coverage spans several countries and language options include English, Traditional Chinese, and Japanese.

Advantages

Using Stone Friend makes it easier to review technique because recording, playback control, and basic editing are combined in one tool. Organized filters and a searchable history help keep your climbing log tidy and accessible for training plans. Built-in analytics provide concrete measures of improvement such as flash rate and average attempts, while competitive features and leaderboards add motivation and opportunities to compare progress with others.

Disadvantages

Language support is currently limited to English, Traditional Chinese, and Japanese, which may not cover all users. Sharing and export options focus on device album and social apps; other cloud integrations are not listed.
