The Peter's Kill Bouldering App is a guidebook to over 200 problems located in Minnewaska State Park. Created by a team of 5 local climbers this is the most up to date information on the problems in the area.
Problems are accessed from a list searchable by name, grade, or star rating. Selecting a problem reveals an aerial map, the description, and a high resolution zoom-able base photo.
The app includes GPS to find the nearest problem, a Tick List, a To-Do List, and lots of filters. It also has a gallery of professional photographs and an informational kiosk for the community to share announcements.
This is the best guidebook currently available for both the first time visitor and seasoned local.
