Keeping it simple. Both on my phone and iPad have Apps that make doing the things I love lots of fun.
I kept it simple for the tablet and only downloaded apps that I know I would use.
Organizing your apps is the best thing you can do for your workflow. Keeping a structure helps, especially during meetings with clients. I'll most likely continue to move items around and make it more comfortable and organized. On the top and bottom edges I keep the apps that are used the most and then organize into folders or clusters, by subject.
The next page has my calendar and other apps that are not as important when I'm editing or sketching. All the scheduling and note-taking apps are on the second page.
The Apps I use for photography, design, sketching, and business are all on my iPad Pro as well as my phone.
The app Notes has excellent new features that are incredibly fun on an iPad Pro using an apple pencil. With, of course, the latest iOS possible.
