Boardsesh is a climbing app that brings popular interactive training boards together in one place. Compatible with Kilter, Tension and MoonBoard systems, it lets climbers switch between boards without changing apps and control connected walls from a phone using Bluetooth. Climbers can browse climbs, see what is currently lit, and build playlists to organize a session before arriving at the gym.

The app also supports shared sessions through a live queue, where a crew can add climbs and stay in sync. A unified profile helps users track sends and progress across boards, and climbers coming from Kilter can transfer their logbook and history. Boardsesh provides a directory of thousands of gyms, club walls and home walls, searchable by name or town, with options to find nearby boards.

Boardsesh is available for iOS, Android and the web. The service is free, with no ads or locked features, and is funded by user contributions. Its source code is available, and the project welcomes bug reports, translations and code contributions.
