For me, Procreate is the killer app that made me want an iPad and my 7 year old iPad Pro is my favorite computer.

I can't believe it's only $13 (I think I paid $10 many years ago). It's one of those rare apps that I wish was more expensive because a $13 purchase doesn't feel sustainable.

I should probably sign up for a Procreate course. The app is so deep that I know I'm only using the most basic features. If anybody has books or courses to recommend, I'm all ears.
