Downloaded a free trial of V-15, but it would not import My old (*.FP3) files from version. 4, I guess one would have to export in *. CSV format, and then import to the new version. To do that would destroy all of the coding, hardly worth the effort of buying the newer versions, since Ver 4 does everything I want to do. Except work on my iPhone. Here's a screen shot.
There are numerous databases that will do what I want on the iPhone, but for me, programming on that tiny iPhone screen with keyboard taking up half of the screen, is a pain I'm not willing to endure!
I use Windows 10 for my GPS, engine monitor system (VMSpc) and tire pressure monitor, so am not ready to convert to Mac or iPad. Guess I'll just continue to travel with laptop, iPhone, Apple Watch. Enough gadgets!
