I like to use mine to read various books and articles in pdf, I find it more comfortable than on a laptop. Apple pencil is also great for quick notes and drawings.

What apps do you use for that?

You can change any app icon on iOS as well, but it is a bit hacky and not as good as on Android.

I’ve heard good things about this app: https://apps.apple.com/app/id1621945342
