21 Best Reading Apps for Your Phone or Tablet

21 Best Reading Apps for Your Phone or Tablet

Tom Gerencer
Reading time: 9 minutes
The way we read has changed drastically in the past few years. While some readers like to keep shelves of books that they can touch, page through, and look at. Others would rather enjoy a good read and then move on, cutting down on dust and clutter. And just because you’ve used one reading app for the past few years doesn’t mean you have to stick with it.
Some new book reading apps come with exciting features, such as sampling titles before you buy or reading library books for free. Most work with or without WiFi, too. Whether you’re more into the latest fiction by Stephen King and Delia Owens or books to boost your business from Stephen Covey or Christopher Voss, we’ve got something for all voracious readers with our list of the 21 best reading apps for mobile devices and tablets.
You’ll notice we’ve ranked each app by star ratings on Google Play and the App Store. We gave preference to selections that get high marks from lots of users on both platforms. Some online reading apps score high on one platform but low on another, which you’ll want to take into consideration as you make your decision. To combat this difference and give you a jumpstart, we’ve chosen the best ebook reading app for each platform in spots 1 and 2.

1. Libby by Overdrive – best book reading app for iOS

If you’re an iPhone or iPad user hunting for a better experience than Apple Books, you just hit the literary jackpot. When it comes to good book apps, Libby by Overdrive is beloved by more than a million iOS users.
It taps into zillions of both ebook and audiobook titles from your local library. Just download the app, log in, and start reading for free. You can read new magazines, too. The app is also on Android, but users report that it can be a bit glitchy on that platform.

Guy Looking at a Tablet
Goodreads is one of the best reading apps for iOS. Apple fans call it a life-changing piece of software for its intuitive layout and the ability to create “shelves” of favorite books.
