Great!

I love that this app is free and has many features that help it compete with the paid apps. My only problem, and it happens with the iphone and tablet, is that I often have to download the new charts twice (sectionals usually). This means as a standard part of my preflight I will update maps then upon checking when the download has completed, that I still have the expired charts! If I otherwise trusted the app I would end up flying on old charts. Its my only gripe but I feel its fairly serious.

Fortunately its easy to check that the charts are current, and I have never had a problem in the aircraft with this app and I do trust it.
