Best Ebook Reader App in 2026

The Kindle app is our pick for most buyers, because the Kindle store is the largest ebook store and the app syncs your place, notes and highlights across phone, tablet and Kindle e reader. The app itself is free, books are bought per title, and Kindle Unlimited, listed around 11.99 dollars per month in recent comparisons, adds a subscription catalog for heavy readers. Accessibility fonts, including OpenDyslexic on supported devices, help readers who need them.

The catch is lock in. Kindle books use Amazon formats and DRM, so moving a large Kindle library to Kobo or another platform is difficult. If you read mostly on Amazon devices and buy new releases, that trade off is fine. If you value moving files freely, look at Kobo or a file reader instead.

Kobo Books is the best ebook reader app for readers who want an EPUB based store and a good e reader to match. The app is free, books are bought per title, and Kobo Plus, listed around 7.99 dollars per month in recent comparisons, offers a subscription for ebooks and audiobooks. Kobo e readers support EPUB and library borrowing in supported regions, which gives Kobo owners a flexible setup.

US buyers should note that the Kindle store is larger for some new releases, and Kobo Plus catalogs vary by country. If you own a Kobo device, use EPUB files, or want a subscription that covers both reading and listening, Kobo is the natural rival to Kindle.

Libby, by OverDrive, is the best free ebook reader app for most people, and it is not close. A public library card opens your library's licensed collection of ebooks, audiobooks and magazines, with offline downloads, position sync and, in the US, sending many loans to Kindle. There are no late fees, since loans simply expire.

Waitlists are the only real cost. A new bestseller may need a hold, and loan periods require some planning. Registering every library card you legitimately hold, such as a home city card and a state program card, widens the catalog at no cost. Start with Libby before paying for any subscription.

Apple Books suits Apple owners who want a built in reader without a new account or subscription. The app is free, books are bought per title, and PDFs and other files you add sit alongside store purchases. Reading settings for font, size and background are easy to adjust, and progress syncs across Apple devices.

The limit is platform. Apple Books works best inside the Apple ecosystem, and its store does not match Kindle for every title. If you read on an iPhone or iPad and buy books one at a time, Apple Books is a clean, low fuss choice.

Google Play Books is a balanced pick for Android users and for readers who switch between phone and web. The app is free, books are bought per title, and you can upload your own EPUB and PDF files for free personal reading. Audiobooks are sold per title as well, which suits listeners who dislike subscriptions.

Customization is solid but not as deep as a dedicated file reader, and the store trails Kindle for some new releases. If you want one app for bought books and your own files on Android, Google Play Books is a practical middle ground.

Moon+ Reader is the best ebook reader app for Android users with their own files. It opens EPUB, PDF, MOBI and other formats, and it offers deep control over fonts, line spacing, themes, gestures, scrolling and night modes. The free version covers core reading well, with a paid Pro version for added features and no ads.

There is no store to rival Kindle or Kobo, so Moon+ Reader suits readers who already own files or borrow DRM free books. If you read sideloaded books every day and care about how the page looks, Moon+ Reader is hard to beat.

FBReader is a lightweight reader for EPUB, MOBI, PDF and other formats, and it runs well on older phones and tablets where heavier apps feel slow. The free version covers core reading, bookmarks and library organization, with premium options for sync and extra formats. Its plain interface will not impress anyone, but it stays out of the way of the text.

Buyers who want a store, recommendations or audiobook integration should pick Kindle, Kobo or Libby instead. Readers who want a fast, simple app for their own files will find FBReader a reliable, low demand choice.

Hoopla fixes Libby's main frustration: waitlists. Its model charges libraries per borrow rather than per licensed copy, so if your library offers Hoopla and the title is in its catalog, you borrow it at once, subject to a monthly borrow limit your library sets. The catalog is strong on audiobooks, comics and midlist titles, plus movies and music in many systems.

New bestsellers are thinner here than in Libby, so the two apps work best together. Use Libby for new releases you are willing to wait for, and Hoopla for instant borrows when you want something to read tonight.

PocketBook Reader is a free reader with broad format support, built by the company behind PocketBook e readers. It handles EPUB, PDF, MOBI and other formats, offers reading customization and offline use, and pairs well with a PocketBook device if you own one. For phone readers, it is a capable alternative to Moon+ Reader and FBReader.

The store side is thin compared with Kindle and Kobo, so PocketBook Reader suits file owners best. If you read your own EPUB library and want a reader that also works on an e ink device, it is worth installing next to Libby.
