The central feature of theCompass mobile application is viewing establishments by the geo location of the device - which is extremely handy when traveling across state borders. On a recent trip from Virginia to New York, I took screen snapshots near the borders which illustrate establishments within a 30 mile radius of our location. I think I'm close to being finished with the Android version; expect the iPhone in early July.
Update: The Android version of theCompass is now available. Happy travels.
