I have a degree in computer science, a field I worked in for several years, before finding my true passion in flying. I currently do contract flying work all over Africa, and keep busy in my off time putting to use some of those old computer skills to make applications which make my flying life easier and more fun.
And then I thought, why not share those applications with other pilots, as I had a look online and I found it pretty hard to find applications which are simple to use, no frills, no fuss, just does the job it was intended to do, without paying a huge price for them.
Try them and see for yourself, I hope you have as much fun and success using them as I did in designing them.
