The unofficial app for University Duisburg-Essen. Currently it supports news, a map with all the buildings, meal plans, person search, studies and recreation.
The lack of an app for windows phone proved to be slightly annoying, especially since the website of UDE has a very complicated setup and it is not very smartphone friendly (and infact does not work correctly under Windows Phone 7). So the solution was to create an app for myself that is tailored to my specifications and the result is a fast and enjoyable one even if I have say so myself!
I will see how much I can update it in the future, but maybe someday I could atleast for WP8 add some Bahn functionality, considering I have a library from my QuickTransit application.
