Fairly sure it’s Mac only. It’s not a 1:1 replacement, but is similar enough for someone like me who’s used Photoshop for 25+ years to pick up quickly.

Whereas I often find myself having to search through help pages and forums when using Affinity Photo.

For many years I didn’t consider a computer a computer until it had Photoshop on it, but since moving to Pixelmator, Affinity and Figma I’ve been able to ditch Adobe completely.
