Best Ebook Reader App in 2026: 9 Apps Compared

Libby turns a public library card into a reading app. You borrow ebooks and audiobooks, set holds on busy titles, and return books automatically when the loan ends. There is no subscription and no late fee in the usual sense, since loans expire on their own. The limit is your library's catalogue. A small library may not carry the newest bestseller in ebook form, and holds can run for weeks. Still, for most readers Libby should be the first app installed, even if you later add a paid store. It is free, it is legal, and it covers a large share of everyday reading.

The Kindle app is free, and the store behind it is the reason most people choose it. New releases, indie titles, and Kindle Unlimited books sit in one place, and reading position, highlights, and notes sync across devices. Send to Kindle lets you add your own EPUB and PDF files, which covers many personal documents. The catch is lock-in. Kindle books do not open in other reader apps in the usual way, so a large Kindle library ties you to Amazon for years. If you already buy from Amazon, that trade is often worth it. If you value moving files between apps, Kobo or Google Play Books fits better.

Kobo is the best non-Amazon store app for readers who care about file freedom. EPUB is the standard format here, so books you buy or borrow in EPUB form move more easily between apps and devices. On Kobo e-readers, library borrowing through OverDrive and Libby is built in, which makes free reading far simpler than on a Kindle. The Kobo app itself is free, with books priced individually and Kobo Plus available as a subscription in supported regions. The store is smaller than Amazon's, especially for some indie titles, but it is deep enough for most fiction and non-fiction readers. If you own a Kobo device, this app is the natural companion.

Apple Books is the quiet pick for iPhone and iPad readers. The app is already on your device, the store is easy to browse, and your library syncs across iPhone, iPad, and Mac. It handles imported EPUB files well, and the audiobook section is strong for readers who switch between reading and listening. The limit is obvious. There is no Android or Windows version, so an Apple Books library does not travel if you change phone systems. For readers settled inside Apple devices, that rarely matters. For readers who switch systems often, a cross-platform app is safer.

Google Play Books suits Android readers who want a store plus a place for their own files. You can buy books, upload EPUB and PDF files from your own collection, and read on Android, iOS, or a web browser. That cross-platform reach is a real advantage over Apple Books. Reading controls are solid but not the deepest on this list. Font, spacing, and night mode cover the basics, while power features like advanced file conversion sit elsewhere. For most readers, the combination of a large store, free app, and file uploads is enough, and store sales make it a good place to build a library slowly.

Hoopla differs from Libby in one useful way. When a title is available, you borrow it at once, with no hold queue. That makes it ideal for comics, backlist titles, and books you want tonight rather than in three weeks. The app also covers audiobooks, music, and video, so it can replace several library apps at once. The limit is the monthly borrow cap your library sets. Heavy readers can hit it before the month ends, especially if they borrow audiobooks and comics as well. Use Hoopla for instant picks and Libby for holds, and the two together cover most free reading needs.

Everand, formerly Scribd, is a subscription service rather than a store. For a monthly fee, you take a set number of titles each month from its catalogue, including ebooks, audiobooks, and magazines. That model suits steady readers who want variety without buying each book. The honest catch is that it is not all-you-can-read. The title-credit system limits how many titles you can take in a month, and the newest releases may not appear at once. Check the catalogue for the authors you actually read before subscribing, and use the trial to test whether the title count fits your pace.

Moon+ Reader is the power choice for Android readers with their own files. You can tune fonts, margins, line spacing, themes, and gestures in detail, and it handles EPUB, PDF, and several other formats. OPDS support lets you connect to online libraries and catalogues from inside the app. The free version covers most reading needs, with ads that the paid Pro version removes. There is no store built in, so you supply the books yourself, from a store, a library export, or your own files. If you read mostly files you already own, Moon+ Reader gives you more control than any store app on this list.

KOReader is built for readers who want control on e-ink devices. It handles PDFs better than most store apps, with cropping, reflow, and margin controls that matter for academic papers and scanned documents. It also reads EPUB and other formats, and it runs on Kindle and Kobo devices as well as Android and Linux. Setup is the trade-off. Installing KOReader on a Kindle or Kobo takes steps that a casual reader may not want, and the interface favours function over polish. For readers with large PDF collections or a jailbroken e-reader, it is the best free tool available. For store buyers, stick with Kindle or Kobo.
