Don't you hate it when you wait twenty minutes for the 51A, and then three show up at the same time? Busboy doesn't prevent that unfortunately, but it does allow you see that all three will be arriving simultaneously.

If you're already waiting for a bus, Busboy can use the stop ID number to tell you which buses are coming, and when they will arrive. Skeptical because of bad experiences in the past? Pick a prediction from the list and Busboy will show you on a map where that bus is currently located (with info right from the bus itself). Not at a stop yet? Busboy can use your location to find all nearby stops within a given range, or only stops serving specific lines.
