The app provides users with an extensive database of pictures, points of interest (POIs), and information about alpine passes. While the app is only available in German, the POIs and routes for GPS can be used in all languages.

The app's main feature is the comprehensive guide to alpine passes. Users can browse through a variety of passes and learn about their history, geography, and other interesting facts. In addition, the app provides users with pictures and POIs for each pass, making it easier to plan a trip or simply learn more about the area.

Overall, Pässe.Info is a useful tool for anyone interested in exploring the alpine passes. While the app's language may be a barrier for some users, the wealth of information and resources provided make it a worthwhile download.
