Acrossair for the iPhone 3GS

One amazing aspect of the iPhone 3GS is the ability to use the GPS and Compass features and an app is awaiting approval from Apple called Acrossair. Coming to NYC soon…

When you load the app, holding it flat, all 33 lines of the New York Subway are displayed in coloured arrows. By tilting the phone upwards, you will see the nearest stations: what direction they are in relation to your location, how many miles away they are and what lines they are on. If you continue to tilt the phone upwards, you will see stations further away, as stacked icons. Only available to Apple iPhone 3GS users.

This is an awesome idea. Check it out below:

I cannot wait to see this in action and see how others apply this technique to other apps.
