I'm a fan of all of the Affinity apps, so when it came time to buckle down and do the layout for a children's book I'm working on, I decided to give Publisher a real look. I haven't used InDesign for years, but Publisher mirrors a lot of the concepts and it all came back quickly. With master pages, text styles, text box shapes, preflight check, built-in photo editing tools, and more, it's a top quality publishing app for $25 (regularly $50, 50% off right now).
