Boardsesh

Boardsesh connects your phone to all the major LED climbing boards(Kilter Board, Tension Board, MoonBoard, Grasshopper, Decoy or Touchstone) over Bluetooth and lights up the holds on your wall. Search tens of thousands of community-set climbs, filter by grade and quality, build a queue, and start climbing.

One app for every board
Pick your board, pick your angle, and browse. Boardsesh pulls from the same climb databases you already know. Filter by grade range, rating, hold count, and more. When you find something worth trying, tap to light it up on the wall.

Build a queue, skip the phone fumbling
Line up your climbs before you get to the gym or between burns. Reorder your list, swipe to remove, and cycle through with one tap. No more unlocking your phone mid-session to find the next problem.

Climb with your crew
Group sessions lets you run a shared session over the internet. Everyone in the session sees the same queue and can add climbs, reorder, and vote. One person's phone controls the board. Works across the gym or across the country.

Track your sends
Log every attempt and send. See your progression over time, check your hardest grades, and look back at what you climbed last week or last year.

Free and open source
No ads, no subscriptions, no paywalls. Boardsesh is open source and built by climbers. The code is on GitHub if you want to contribute or just see how it works.

Requires Bluetooth Low Energy (BLE) for board connection. Works without a board for browsing, queuing, and logbook features.
