I used to do a lot of computer programming, never did much that required graphical interfaces but looking at the apple side of it it shouldn't be too hard for somebody to make something that is capable of at least tracking the normal stats like number of flights, flight times, gallons, comments etc. My problem is I haven't done any of this type of stuff in about 10 years and I'm afraid it would take me way too long to get up and running but some college punk getting their degree in computer science oughta be able to stamp something out like this over a few days for a case or two of beer. It would also be cool to have a way to track the time on a single engine as well, say if you have had an engine that has been swapped through several airframes and have that info carry along with the engine.
