String, Doug, kernelpanic - thank you for your responses. Indeed, the
option with lite/pro & LVL looks most reasonable to me at this point.
What I was really hoping for is that I'd missed something in the in-app
billing documentation, and it's possible to use it for trial period checks.
Especially since it would be really easy for Google to implement, as a
special item type (in addition to the current managed / unmanaged ones),
where a transaction goes through and is maintained by the server, but
the customer is not charged anything.
It would also be possible to do this without a special purchase type, by
having a zero-price item, except the docs specifically prohibit that.
Oh well. I'll look into writing a dungeon game, with healing potions for
sale :)
Thanks,
-- Kostya

I've been doing lite/paid versions since the market first accepted
paid apps and it's worked well. The downside is that the people who
go paid then uninstall the lite, which presumably hurts its ranking.
You could try getting around that by implementing an unlocker app as
the paid version so the user has to retain both in order to get the
full benefits. The downside to that might be reduced ratings/reviews
for the paid unlocker, which could hurt its ranking.
