Its ok.

Im a truck driver who hauls oversize loads, where sunrise and sunset times are critical. An error can cost around $500. So far this app has done well as far as accuracy is concerned, but it would benefit from a better list of cities. I find myself hoping I have wifi so I dont have to set my position manually on the map. This app is trustworthy, but would benefit from additional development and patches.
