Excellent

Very nice audio tour. Just enough info. You start the app and just drive, when you pass a GPS trigger point it gives you specific timely info. You can run a GPS map in the background to have turn by turn directions if you like.
Somehow it seems that when returning on the same road it doesnt play the same thing again which is nice. I rarely give a 5 rating to anything but this app gets one
