For my next trip to Europe I wanted to be able to consult city maps without using 3G, and in places where WiFi is unavailable. For London, this has all the detail needed. Even small streets are marked--and searchable. (The same person makes apps for other cities. The map for Munich ミュンヘン was not as detailed.)
