Neal,
Obviously I don't know how many users of APDL (win/palm) are out there, but I will say that an android and iphone version of this software would be a HUGE seller. Almost everyone I know who carries red books to hand write their times, or an old brick with win/palm APDL on it also carries one of these 2 types of phones. Just as you developed (a decade ago), APDL for the 2 predominant mobile platforms, it is time to work on a new one, or you risk losing a fairly substantial customer base.
I for one will switch to the 1st android airline pilot tailored logbook software package I can find, and I'm willing to spend between $50-100, as long as it can do for the most part what APDL could do and export to a CSV so I can import it into LBP. So would you like my $ or should I spend it somewhere else?
Do a poll of your users, send out an email and put up a forum thread, I bet you could finance the project with prepaid subscriptions, offer it at say a 25-30% discount and guarantee a working product within 4-8 months, and voila, there's the cash flow to bring on the help that can bring this product to market. That or take out a loan, you will make the $ back. There's no doubt in my mind that you can sell 2000 "subscriptions" for this software. 2000*$75= $15k, not to mention the schedule importer residuals. So Neal, please bring this to market, or tell us when to expect it, and be specific.
Coz
