Excellent product
The features of this app compete with ForeFlight, Garmin and WingX. How ever if you use a flight sim and wish to log your flights and post to the web, this is the only one that I found could do it. The 3D terrain Modeling along with airspace diagrams on the elevation graph, make this app very unique. Great job, I look forward to future enhancements.
