Not very good. User unfriendly. Wrong information.
If NSW can do a better app, you know you are in trouble. PTV, do yourself a favor and just license the one that NSW got from some German company. This an update: not only is it hard to use, the information is wrong. Said my train went to Southern Cross but it doesnt, it terminates at Flinders St. Due to Metros lack of use of announcements I only know about it when the train reverses direction. BAD APP.
