I love this app! It looks great, and is easy to figure out. My only complaint? I wish there were more routes included on the map. For instance, the route 88 bus which travels past the Tate Britain. Its one route that takes you through Whitehall, past Trafalgar Square and up Regent Street. It passes by many places that tourists would be interested in. If route 24 is on there, I think 88 should be too.
