The app is basically a little bridge to feed data from Microsoft's abandoned but still popular Flight Simulator X into popular iOS aviation apps ForeFlight and WingX. It was my first time building an app for Windows or writing C#. Coming from the iOS world I found it a useful exercise. I built mostly for myself. I had previously been relying on a Rube Goldberg solution of bluetooth dongles and jailbroken iPads. I figured I could throw it up for $5 with gumroad and see what happens.
