Search nearby stops and view info by stop number (note that stop number is not the same as the bus number) !
The Mississauga MiWay App will list all busses at a stop including when they are arriving and where they are going. Data is in real-time from Mississauga's Open Data GTFS (Transit Feed System). You can also use it to find nearby stops. You can get details (bus speed, etc.) on the bus by clicking on it. You can also search your stop number in the home screen or using the Search button.
It is a very simple app that just works!
