Tripwolf allows users to have a complete travel guide with maps included, so that you don't need access to the Internet at any time. This is particularly useful if you keep in mind the problems you usually experience with 3G the moment you get to another country.
The app has other awesome benefits, like a trip planner that knows exactly what to do at each place, an augmented reality viewer that recognizes places just by holding up your camera in front of them, members of the Tripwolf community who have different types of information, and a whole lot more.
Through the app, you can buy maps and specific itineraries for different city from its own interface. This is especially helpful in preparing for very specific trips.
Tripwolf travel guide with offline maps (London, Paris, New York, Berlin, Vienna, Barcelona, Amsterdam, Rome...) is a great app for any user that wants to go on vacation and enjoy everything that their destination has to offer.
