Very helpful app!
I love this offline app that allows you to pick spots you want to go to, drop pins on them on a very useful map, calculate distance between places, and create notes. Some sights (Reichstag for instance) even have detailed background info you can read offline. Listings vary though; some have just urls, some list hours and addresses. Also, if the place youre looking for isnt already in this system, I couldnt see how to drop a pin on it. We used the map all the time though - the GPS on it was excellent, and having different coloured pins available was great.
