Check a boulder before you try it
See the grades other climbers have given it and read their comments. When you send it, log your own grade.
Share and grade boulder problems
Crimpstack is a logbook for bouldering gyms and home walls. Take a photo of a wall, mark the holds of a problem, and see what grade other climbers gave it.
What it does
Add your own problems
Photograph a section of the wall, then draw the line or circle the holds. Give it a name, a grade and a description.
Get feedback on a set
Route setters can register several boulders on one photo of a wall section and see how climbers grade them.
Keep track of a home wall
Use one photo of your spray wall and add new problems to it whenever you like. Private areas are only visible to the people you invite.
Your ascents and a to-do list
See what you have climbed and how your grades are spread, and keep a list of boulders you want to try next.
