Data problems reduce effectiveness for bus routes

Its a great app when the bus data are accurate, which is about half the time. The other 50 pct of busses mysteriously appear and disappear. And some scheduled buses never appear at all. For others the arrival time changes significantly from minute to minute. Ive had the app for 3 months and have returned to relying on the paper schedule.
