Climb Grader is an online web application that climbing gyms can use to allow their patreons to communicatively grade their indoor climbing routes using QR codes that are unique to the gym. Climb Grader is currently in development and will hopefully first be tested at the Colorado University of Boulder's climbing gym.
Gym's using Climb Grader will have a QR code and 5 digit number next to the route(s) you can grade.
Your gym owner or manager will give you a QR code to login with. When you are finished setting a new route in your gym :
Note: If the 5 digit code to a climb is lost at any point the easiest solution is to create a new route and reset the grading.
Note: Accounts without activity for more than 30 days will be deleted.
Note: gyms can have a maximum of about 50,000 routes at once. Only gym owners can prevent particular routes from being replaced by a newly generated route.
