Best Ebook App in 2026: 9 Apps Compared

Kindle is the safe default for most readers because the store is so large and the reading experience is consistent. Books sync across the app, the web reader and Kindle e-readers, and features such as highlights, notes, dictionary lookup and adjustable fonts are well developed. If you read a lot of new releases and bestsellers, you will rarely hit a gap in the catalog.

The main cost is lock-in. Books bought from Amazon are meant to be read in Kindle apps and on Kindle devices, so switching later is awkward. Kindle Unlimited, at $11.99 per month in recent listings, suits heavy readers who enjoy its catalog, but it does not include every major new release. Buy Kindle for breadth and convenience, not for open file freedom.

Kobo Books is our pick for readers who care about open formats and e-reader choice. It handles EPUB files naturally, syncs with Kobo e-readers, and offers deep reading settings for fonts, margins and layout. Kobo Plus, listed at $7.99 per month for ebooks and $9.99 per month with audiobooks in recent listings, gives subscription readers another route beyond single purchases.

Kobo does not match Kindle for sheer catalog depth in every genre, and availability can vary by region. For readers who already own EPUB files or who want a Kobo e-reader, those limits matter less than the format freedom. If you value owning files you can move, Kobo is the strongest mainstream store here.

Apple Books is the simplest choice if you already live on iPhone, iPad or Mac. The app is built in, the store is easy to browse, and purchased books and audiobooks sync across Apple devices. Imported EPUB and PDF files sit alongside store purchases, which helps readers who mix bought books with documents and older files.

The limit is obvious: there is no Apple Books app for Android or Windows in the same form, so your library does not travel well outside Apple hardware. There is also no all-you-can-read subscription to compare with Kindle Unlimited. Choose Apple Books for polish and convenience inside the Apple world, not for cross-platform freedom.

Google Play Books is the most flexible mainstream app for readers with a personal library. You can buy books individually, upload your own EPUB and PDF files, and read across Android, iOS and a web browser. That mix suits readers who have collected files over years and do not want another subscription.

Discovery and recommendations feel thinner than Kindle, and some readers prefer a dedicated e-reader app for long sessions. Still, for cross-platform reading without a monthly fee, Google Play Books is hard to beat. It is also a good second app for Kindle or Kobo owners who need a home for loose files.

Libby, from OverDrive, should be the first app most US readers install. With a public library card, you can borrow ebooks, audiobooks and magazines for free, download them for offline reading, and place holds on popular titles. There are no late fees because loans expire and return on their own, which removes the main worry of library borrowing.

The catch is availability. Your library buys a limited number of digital copies, so a new bestseller may mean a wait. That trade is easy to accept when the price is zero, and many readers pair Libby with a paid store for books they cannot wait for. If you have a library card and have not tried Libby, start here before you pay for anything.

Hoopla works differently from Libby. Many titles are available instantly, without a hold queue, because libraries pay per borrow rather than buying a fixed number of copies. That makes Hoopla a good companion app when Libby has a long wait for the book you want. Comics, graphic novels and other media add value for households that read in several formats.

Your library sets a monthly borrow limit, so heavy readers can run out before the month ends. Hoopla also depends on your library taking part, so check availability first. Used alongside Libby, it covers many gaps and keeps reading free, which is why we include both library apps in this list.

Everand, formerly Scribd, suits readers who want one subscription for ebooks, audiobooks and magazines. The standard plan is listed at $11.99 per month and includes one premium title credit alongside a wider catalog. For readers who finish several books a month and enjoy mixing text and audio, that bundle can be better value than buying each title alone.

Be clear about the model before you subscribe. Everand is not unlimited access to every book, and premium titles are controlled through title credits. If you mainly read new bestsellers on release day, a store such as Kindle or Kobo may serve you better. If you read widely across backlist titles, Everand is a strong subscription pick.

Nook is the natural choice for readers who already buy from Barnes and Noble or use a Nook device. The app is straightforward, books sync across supported devices, and the store covers a wide range of fiction, nonfiction and children's titles. For US readers who like the idea of a bookstore-backed library, Nook feels familiar and grounded.

The ecosystem is smaller than Kindle or Kobo, and Nook devices are less widely sold than they once were. That does not make the app a poor reader, but it does mean you should check device plans before building a large library here. If you already shop at Barnes and Noble, Nook is a logical and low-friction home for your ebooks.

Moon+ Reader is for Android readers who already have files and want full control over how they look. It offers detailed typography settings, themes, gestures and library organisation, and it works with files from your device and compatible online sources. Readers who care about layout, night reading and custom controls will find more here than in most store apps.

Moon+ Reader is not a store-first app, so you will need your own books or another source to fill it. It is also Android only, which rules it out for iPhone readers. Pair it with Libby, Kobo or Google Play Books for content, and use Moon+ Reader as the reading surface when control matters most.
