Looks like a great product; the question is... who gets paid for
thumbing through every country's AIP, supplements and amendments to
it, and updates the database.

Paid? They are supported by donations. The information comes from
volunteers and from governmental database information releases...

That's why, for VFR, I use Navbox (www.navbox.nl) because one of the
two creators does exactly that. It's not a free program (although its
cost is practically zero on the scale of aviation costs) and that
enables the database to be updated.

And it appears that you not only pay for the software but for the
database updates as well. Both are currently free with PocketFMS...

It's like the CoPilot project. I spent a while playing with it; it's
next to useless for Europe.

One needs to be able to reasonably trust the flight planning product,
otherwise one has to duplicate the whole job with something else.

GoldenEagle Flightprep is an excellent flight planner, that also happens
to be free...
