If you happen to be clutching an iPhone and you live or work in the Philadelphia area, SEPTA has developed a nice iPhone application: iSepta.org. (Click on the link from your iPhone.)
What makes this interesting is that SEPTA’s website is pretty inconvenient for finding train schedules, but this iPhone optimized website is quite brilliant. You simply enter the start and end points and it shows you what trains and the schedules of the next five running. Even though it is a small audience, more public transportation services should see this example.
The application is executed perfectly. It answers the user need: “I’m in Berwyn and I need to get to 30th Street Station…(tap…scroll…tap)…Ah! The R5 and it leaves at 10:34am. Thank you, iSepta.org!”
