Currently one of my colleagues and I are developing a new version of the TUGSearch app (app for the TUGraz where you can search rooms, lectures, people,...). The current App Store version is out-dated and has to be updated for new iPhones and iOS versions, which is the reason why we 2 are pleasured to develop the App in one of our lectures.

After the lecture my colleague in I aren't responsible anymore for updating the app.

Edit 2020: Caused by the newest iOS updates and various operating system changes, the app's UI needs now to be updated in some places.
