As for Filtr pricing, it seems the consensus is that a subscription is good as long as there’s a one-time purchase alternative, so I think I’ll go for that!
@mipstian @CyberSaloperie @ddlevine Honestly, I don't think there's any need for an app that needs continuous updates to have a one-time-purchase option.
It's unreasonable to expect that a developer will invest continuous work, forever, for no additional money.
Enough people will subscribe for ongoing value. You don't need to sell yourself short to please the handful who won’t.
