Nothing like that for me. Sometimes I've had to log my routes either into UKC directly (at the crag if I have 4G or home later on other days), but that's about the biggest problem. Not carrying around 500 grams of paper is much appreciated at time, or I take Rockfax on my phone and the BMC paper guide in my pack.
Gary's website is an amazing resource but I don't find it nearly as easy to use on my phone as the Rockfax app and there are now quite a few new sectors at, for example, Goddard's that aren't covered on sportclimbs yet. The app is nearly complete, although I do often use it in conjunction with UKC logbooks when phone signal allows.
The app is superb when you get chance to travel. Last few trips to the Lakes and North Wales it has been useful and last summer meant I could research loads of different crag in Dorset when I was down there with the family.
