Legal much content, but unfortunately does not consider public transport.

When I was 3 days in Vienna, I bought the app. Content can not complain, attractions and hotels were all inside one. The explanations are sufficient. You can leave plan routes with timetable Also, when you say when you where you want to go. So a good cheaper substitute for a guidebook.

Unfortunately, the app does not include any underground and trams no. Instead, she suggests 90 minutes before walking. That is not so in practice. It also contains no routing and no timetables, so that you yourself could look. Perhaps the meantime it. The navigating with me has not even work properly. Since I had to resort to Google Maps. That's why only 3 stars.
