Which Mountain? (Switzerland) app for iPhone and iPad

Do you know the exact location of the Matterhorn, the Eiger or the Umbrail Pass?
Test your knowledge with the Which Mountain? (Switzerland) app !

In the quiz a white dot is displayed on a red map of Switzerland and four possible mountains/passes are suggested. Now you have to work out as many correct answers in the shortest possible time by touching the correct name. If youre not sure about a question, you can play the joker and two mountains/passes will be immediately removed.

Features:
=> 220 mountains and over 100 passes in the index
=> Play just with mountains/just with passes or with mountains and passes
=> Three different levels of difficulty
=> Three different game durations
=> Joker
=> An extensive ranking list/scoring

I would be grateful for further comments and any suggestions for improvement.
