A solid app with a good UI - missing one key feature.

This is a very solid, well written application. The support for geoPDF maps is incredibly useful for our GIS users within our aviation company

Caveat:
This app would be rated 5 stars if you could record and view your track, then email it as a gpx or kml. I have another app that does this is and allows for the use of custom maps but is badly written and a pain to use.

I would pay for GPS track viewing and export capability in this app. Hint Hint.
