Bristol Map and Walks

Open appp, click on item ,screen goes dark, get message downloading images - for 20 seconds! Then get told no internet connection. Can however read text if wait for 20 seconds! Also locks ENTIRE phone for that time which indicates worrying lack of knowledge on part of developer- particularly crap when happens in paid for app. Decided to have a look at the map and find out where to find Banksy instead. Map is blank! Great! Sooo glad I paid the money... Tells me gps is off (correct - i know where i am but i just don't know where the art is). Presume for some reason app has to have gps - so I obligingly turn it on (again incredibly crap development work in paid for app!) but then obviously I'm in built up area between high buildings (who'd have thought it? In the middle of Bristol? Just not the developer!) so phone can't actually locate me using gps. Guess what, map still doesn't appear. Tells me my location is unavailable!!! Duh! Despite not being able to get GPS signal I know where i am, i can read Street names, give me a map, like you pretend you're gonna, and I'll go find the art.

Some of the tours are only descriptions with no link to route or list of waypoints. Other when you click the link to view route, it demands you pay $4.99 for an upgrade to be allowed to view it. Total waste of time.
