Apple Books

Apple Books is the easiest way to start reading immediately because, as you would expect, it works great on your iPhone. If you’ve never used it, it’s worth a look. 

The app has gotten better at the little things that matter in your everyday experience, like making text comfortable at night, keeping your place automatically, and letting you highlight passages without fuss.

The reading experience is clean and straightforward. You can adjust fonts, themes, brightness, and line spacing until it feels right for your eyes. And if you’re the type who likes to underline ideas or save quotes, the notes and highlights stay organized, which makes it surprisingly useful for school, research, or even just remembering what you liked in a book.

If you also use an iPad or Mac, syncing is one of the biggest advantages here. Your progress and notes can follow you, so you can read on your phone during the day and pick up right where you left off later on a bigger screen.

You can buy any type of book inside the app, or load in your own PDF files in case you want to study or read an important paper from the same place. It also supports audiobooks, whether you’ve purchased them from Apple’s Book Store or Audible, although you’ll need to load your Audible books in manually as there’s no direct sync.
