I found this web application for the iPhone last week (http://www.sofianehassaine.com/iPhone/BusTracker/). It takes all of its information from the UW ITS Mybus program, however it improves the interface by leaps and bounds. All you do is choose your location and it will show you estimated real time arrivals for all buses that stop at that location. The design and user interface is very good. I have used it a few time and it from what I can tell it works great. Best of all, you can run it on your PC at home or work.
Despite this there are a few interface issues. For example it sorts by route not arrival time. Also the destination identifier has redundant information that makes it hard to read the important information. I would also like it if you could pick stops using presents, google maps, or neighborhoods.
