Nether Quando

This is the unofficial app to show real-time data of the Wiener Linien, calculate routes from A to B, find stops and get timetables.
Nether Quando also released the official Windows Phone app to schwarzkappler.info.

This app offers automatic updating of departure times, graphical representation of the routes on a map, location of the current position via GPS and localization of the next stop, fault display, online shop for tickets, reports on ticket checks, as well as advanced setting options.

It is possible to quickly access previous stops or routes via a history and particularly frequently used stops can be set as favorites or pinned to the start menu.

Nether Quando is completely free and ad-free.

It uses open data. Data source: City of Vienna – data.wien.gv.at
