A route guide for the rock-climbing routes at Struben's Valley in Johannesburg (South Africa), allowing you to leave that dirty, dog-eared, and now barely legible set of printed wiki pages (half of which are missing anyway) at home.
This initial release includes just the basic functionality - a list of the routes, their grades and protection, as well as the detailed route descriptions.
Also included is a Google map of the area and a some general information that may be useful to anyone new to the area.
Although the guide is useable on a tablet, it really is primarily designed for use on a phone at the crag.
