Just putting it out there: The Affinity suite for the desktop is currently 50% off. The Designer app for the iPad works great on my Mini with good Pencil support, and I've used the desktop apps for a long time. It saves to iCloud (you can choose another place since it's a plain old Files path chooser) and the files open up on the desktop app with no problem.

Capture One Express is a free and highly functional alternative to Lightroom if you have a Nikon, Sony, or Fujifilm camera.
