Very frustrating
The interface is fiddly, forces Apple maps for navigation, crag descriptions are very short (presumably less than in the print version) and apart from a tick-list misses every feature that would make an app worthwhile. - Such as bookmarks for crags, GPS of the crag and not just the parking spot, or ANY kind of community feature (like rating routes and crags of leaving comments about the current state of a route)
Hope this review helps to make this a worthwhile app and not just a poor excuse for an eBook reader.
