In reply to Paul Phillips - UKC and UKH:
It would be a great feature Paul - I was at an unfamiliar venue last week, with patchy mobile. I had the Rockfax bouldering guide and UKC listed a blend of RF content, Vertebrate content and a few other bits of pieces. Being able to look at the offline content would have been brilliant to reconcile what I saw in front of me with the guide and other problems. I get what you say technically, no small task I'm sure.
