(the above written quickly on the Medium app on iPhone. A few more bits added below)

I’m not saying the appstore is a perfect platform. Emanuel Sa from Bohemian Coding points this out in the same comment linked above:

But the biggest problem is the platform. Apps on iOS sell for unsustainably low prices due to the lack of trials.

It will be interesting to see what — if anything — Apple does to support the development of a pro ecosystem.

My perhaps somewhat flippant comment about moving beyond unit sales points directly at the opportunity. Sketch Mirror is another tiny little unit sale that doesn’t really do all of what people need. My company pays for Marvel every single month — but live in Sketch. Maybe Sketch should have a longer talk with their SaaS partners about some revenue sharing or affiliate models.
