Thanks for your comment. I was just about to waste time researching Procreate under the false impression it was vector.

By the way, if anyone is interested in a vector drawing app, I highly recommend Concepts.

Not even Photoshop -- Photoshop is mainly about editing, well, photos, while ProCreate is about natural-looking brush painting. Photoshop certainly has brushes, but it's not even attempting any kind of naturalism. People don't generally "paint" in Photoshop. [Edit: from comments below, I stand corrected. Guess it's just the people I know.]

I'm not sure what you call that category of app -- painting apps? Natural-media painting apps? (Although you can choose to make them quite unnatural-looking too if you want.) Fractal Design Painter (later Corel Painter) invented the category I believe, way back in 1991.

And only the digital painting parts of Photoshop, not photo editing. Which isn't to say that it's not a great app! It's just not a full on replacement for Illustrator of Photoshop.

If you want an alternative to Illustrator or Photoshop, Affinity Designer or Affinity Photo are more in that vein.

The direct competitor is Fresco I think, Adobe's drawing app for iPads

From context "Easter" was probably autouncorrected from "raster".
