With the ‘Join in!’ app for iPhone, Android and Windows Phone, citizens can report shortcomings or grievances, such as potholes, to their community in a non-bureaucratic and quick manner. For Vienna, the maps of the city of Vienna are offered via the [city map interface] (https://www.data.gv.at/katalog/dataset/332be1f6-5791-43ae-9e37-90cc48e75d24/) with a wealth of value-added functions and unprecedented accuracy. The notes are handed over from the app to the Viennese city administration.
