Tokan Boulder Grid

Build a personal library of bouldering wall diagrams and training records with Tokan Boulder Grid.

Create a schematic wall with a chosen number of rows and columns. Place geometric hold markers, give them names, shapes, sizes and categories, then select a sequence to form a route. Mark starting and finishing holds and save the diagram with your notes and a personal difficulty rating.

Organize walls in Wall Library with names, dimensions and comments. Use Route Builder to create variations, duplicate a saved route and revisit changes to your diagrams.

Record dated attempts for each route with an attempt count, Completed or In Progress status and your own comments. Quick Attempt Entry adds another record to the selected route. Compare routes by hold counts, sequence length and your difficulty ratings. Local summaries show walls, routes and completed attempts. Export routes and training history as JSON.

Tokan Boulder Grid works offline without registration or cloud storage. Records remain on your device. It does not use a camera or movement sensors, assess route safety or hold strength, or provide climbing-technique recommendations. Diagrams and results are entered manually.
