This particular case is proof that yes: for certain services we happily pay a modest recurring service fee.

Edit, clarification:

- this does not mean that I want to pay an monthly fee to use pro features on static apps. Anyone who does this instantly loses a star in the review as soon as I get around to it.

- however I also understand and appreciate that I sometimes can pay a higher up front price to support the developer(s) for apps that works offline without a service connection.

- feature keys or even donation addons etc to support further development are also well received. This nicely aligns the incentives for developers/users.

- and finally, for some select projects I would think it would be OK with a subscription that gave me all new features as they arrived.
