About this app

The Gunks app provides digital guidebooks for rock climbing and bouldering written by local authors.

Climbs are accessed from a list, which can be searched and filtered. Selecting a climb reveals a base photo, the route's description, and a high-resolution zoom-able aerial photo, topo, or GPS-enabled map. The photos include belays, descent information, variations, and new link-ups.

The app uses GPS to provide navigation and find the nearest climb. It also includes a Tick List & To-Do List with cloud backup.

This app was created by local climbing fixtures Christian Fracchia and Byron Igoe, and further content was contributed by Andy Salo, Char Fetterolf, Lee Hansche, Marty Molitoris, Victor Medeiros, Dana Seaton, Chris Redmond, Charlie Schreiber, Tim McGivern, John Byrnes, Melissa McNell, Ben Blackmore, Rich Shoemaker, Austin Hoyt, Conor O'Hale, Justin Sanford, Kayte Knower, Tom Chervenak, Hillary Guzik, Paul Jung, Tim Keenan, Aleks Shineleva, Ted Coffelt, Thacher Park Climber Coalition, Ryan Shipp, Seth Derr, Larry Felton, Kyle Matulevich, Mike Rawdon, Chris Lopez, Charlie Schreiber, Rich Shoemaker, Dana Miller, Robin Close, Eric Marx, Sabrina Crispyn, Gary Thomann, Jim Lawyer, Jeremy Haas, EPAC, Andrew MacNamee, Kevin Johnson, Samuel Hayden, Justin Meserve, Tylor Streett, Peter Treitler, Justin Ridgely, and more.

The Gunks app is an indispensable resource for both the seasoned veteran and the first time climber.

GunksApp is the best thing to happen to climbing since cams. Like... you *could* go without it, but man does it make things easier, more fun, and improves your redpoint by three full grades. Honestly, though - I recommend every person who comes and visits me to climb up at the Gunks, download this app. The pictures for every route start (and zoomed out topos) are clutch. I have stopped mid-lead to take out my phone and confirm my route-finding choices more times than I care to admit, and always appreciated having such high quality photos and descriptions in my pocket at all times!

I started using gunksapps from the very beginning and now have at least a dozen guidebooks from them. By far my favorite guidebook app. Intuitive to use and lots of great crags to choose from. My only wish is that I could travel more to give me an excuse to buy some of the more distant crag guidebooks.

Incredible app 👌, if you're into rock climbing this is a must have. Find a suitable climb in the app, and let it navigate you right to the base, no wandering, no guessing. get stuck somewhere? use the photos to know for sure where the route goes.
