That's exactly the right analysis.

More generally, there seems to be an entire class of apps out there that could be really useful, but which are really hard to monetize with subscriptions and/or ads revenue alone. Think about an advanced file converter, or maybe a one-off fax service.

Minno provides an effective alternative to monetize these services, and it does so with much more ease than with traditional payment systems.
