The Gunks Apps are a phone app available for Android and IOS.
You can purchase separate licenses for content to Trapps Routes, Nears Routes, Trapps Bouldering, Nears Bouldering, and Peterskill Bouldering ... and areas across the country.
Each guidebook includes route details, a tick list, filtering, and GPS/compass navigation.
Each route has a high-res base photo, high-res aerial topo and/or maps, and pitch-by-pitch description including descent info.
Search the list by grade, protection, ticked status, or stars.
Unlike print books, the apps are kept up-to-date with new climbs, photos, closures, and condition information.
