Occasionally accurate
An OK implementation of the ATAC on-line bus information system, with some good and some bad. Nice to be able to look up a bus route number and see all the stops mapped -- but you have to know the direction by the end point of the route, which is a mystery. Nice to track the route on a live map as you go to enable getting off at the right stop. But the app appears incapable of reliably telling you when a bus is coming to your stop, and on Sundays in particular is poor at saying if the bus will come at all or if it does, if it will stop. The route planner is OK but also unreliable for several reasons. One minute it will tell you to go one route, the next will be completely different. And the planner tells you to walk to specific stop numbers but doesn't show or map where the stop is, just how far you are from it -- poor when there are a lot of stops around. This gets very frustrating when you have a 1 min connection and you don't know where to go. Still, ProBus is the best of the generally poor apps out there.
