Ratings and Reviews

Looks great but issue with USA airspace


The app looks great but I cannot get the airspace to show up. The USA txt file u point it to has changed so I paste in the latest one. It downloads and uses it but the do not show up on the map. I have iOS 6 on iPhone 4.

Nice tracker for Leonardo


A lot better now with the black background.
