rakkup allows you to access an entire bookshelf of climbing and backcountry skiing guidebooks on your iPhone, even beyond the reach of cell phone coverage. Once downloaded, guidebooks work offline with no Internet connection! It is also the first and only mobile climbing app that navigates you through the trail system to your climb, turn by turn. Produced in partnership with Outdoor Research, rakkup reinvents the guidebook for the smartphone era. We've partnered with Beacon Guidebooks, Wolverine Publishing ,and other publishers to bring you rich guidebooks complete with color photos and topo drawings. Free sample climbs and ski descents are included. Browse climbs and descents on a map or in the list format of your choice, filter and search in seconds, then navigate using your phone's GPS with a single tap. In climbing guidebooks, the app continuously calculates the easiest route through the trail system from your current location. Simply follow the arrow and moving map. Note: When actively navigating to a climb, rakkup uses GPS in background. Continued use of GPS running in the background can dramatically decrease battery life.
