GeoDistance

This app is design for people who are working outside and want to calculate distance between points using the build-in GPS of their iPhone. The result will be as good as the precision of the GPS.

To calculate the distance, since the earth isn’t a perfect sphere, we are calculating the earth radius according to your position on the earth. We are also considering the altitude of your position to be as precise as we can get.
