If you want a program to run on your computer, I don't know. Theres only two that I know of, and flightlogg.in that are free, but those are website based. I suggest you find one that doesn't have a 'free trial' link anywhere or is otherwise is not free, at least to start off. There seems to be about 50 or so electronic logbook programs out there. I want to get a proper Pro paper logbook but also want a back up electronic one. What electronic logbooks are folks using? My GA logbook is just about full and I need to buy something new.
