Looks REALLY promising, Jon. Oh dear...another photo app to explore!

The folks at Affinity seem to be aiming high; they've also got an alternative to Illustrator called Affinity Designer.
Definitely a company to watch, and if you're looking for a PS alternative, it looks like it might fit the bill. Wish I'd noticed this last week - up until the 23rd, the app had special pricing for the launch. Oh well.
Let us know how you like it if you decide to try it!
