reminds me of the problem I have when trying to install WiFi Heat on my android pad :
My building in not straight East/West. And I frequently work in buildings not yet on google maps.
I need the ability to point at two points on a map, tell how far apart those points are, and have the app do the math with the scaling.
It's almost perfect. If you make this update, I'm sure I'll purchase the app again.
