I've been using Localscope (US$2.99) since its debut. Localscope is a discovery app that gets data from 20 different sources to show what is around you with useful background information.
The overhaul for iOS 7 looks very nice, with new colors and transparency. Controls disappear in context to what you are doing, so everything is very clean.
I tried the app this morning while sitting at the St. Louis airport waiting for a flight. Immediately, a map popped up showing my location, and there were guides to the closest restaurants and other facilities the airport offered. There were even Wikipedia links to more general information about the airport.
