For a small dev I think it's difficult now the big app stores have conditioned so many to believe free, £1.99 and £3.99 are appropriate price points for software. That only works for the tiny few that get a viral lottery win.

I see the attraction of a sub as implicit copy protection. So I wonder why there aren't more ISVs putting the yearly sub markedly lower than the former licence price.

Scrollaway makes great points about microsubscriptions. I think he's right that a central place to easily manage multiple subs would take away most of the pain. Banks seem to specialise in awkward UX and statements that just show "UnknownCo LLC Service" because they're the parent company of coolthing.com's service. Patreon might be better placed to have a try here.

Right now I'm having this battle with myself as the side-project I'm slowly progressing looks like having a sub might be right. I'm still reluctant. Oh the irony. :)

Good luck with your creations.
