Since my ancient OS X version doesn't work with Affinity apps anymore, I've been using the iPad versions of Af. Photo & Designer. They work great! There is hardly anything missing from the desktop versions, and the strategies for replacing key shortcuts & mouse buttons with gestures are very clever, and become intuitive quickly. And in Designer for iPad you can draw vectors (brush tool, not pen) with the Apple pencil, which could be really helpful for many people. As you know, any Affinity file can be seamlessly traded back & forth on both platforms, and between Photo & Designer.
