I love Affinity Photo on the desktop too.

I have to imagine it will do amazing stuff on the new M1 iPad. (focus stacking about 20 RAW images from a 5D3 on Affinity Photo on an iPad Pro 10.5' 2017 model.took only a minute or two.no crashing, and did quite a good job!! I got all 3 for desktop and also got the iPad versions which are amazing what they can do even on a 2017 iPad Pro!!!!! Hard to beat at that price, $25 each for Affinity Photo, Designer and Publisher. I believe all of the Affinity products are still on sale.$25 each. Working in combination with DXO or C1 and tiff output works well for me anyway for the ace noise reduction. There has been rumours for ages about this but for now nothing. Also there is no cataloguing feature which for me goes hand in hand with raw development. The downside, forget the raw development module, sadly and frankly they just got it so wrong it could have been genius but i suspect that project file sizes would have been an issue, ah well perhaps that will be the big thing in v2. Key things for me, everything can be done on adjustments (non destructive) so i cant think of when I've ever had to do anything that i couldn't reverse. Because it's new(ish) the codebase is modern (and clean). Remember that its actually a suit of apps that fully integrate with each other with a common project format, a lot of graphics artists are using/moving to it. It's easy to learn especially for photographers that really only need a subset of the functionality. I do a lot of panos and stitching with it and am rarely dissapointed with results.
