The best EPUB reader for Android in 2026

Short version: take ReadEra if you want free and calm, Moon+ Reader or Librera if you want to configure everything, KOReader if you love typography and e-ink, PocketBook if you borrow library books with Adobe DRM, Kindle if your books come from Amazon, and Lectern if you want a book read aloud in a voice you actually enjoy.

How to judge an EPUB reader

Feature lists are long and mostly irrelevant. Four things decide whether you keep an app:

• Does it render the book the way the author set it? EPUB is HTML in a zip. Bad readers flatten everything into one typeface: poetry loses its line breaks, drop caps vanish, scene breaks become an anonymous blank line.
• Can you make the page comfortable? Size, spacing, margins, theme, and how quickly you can reach them.
• Can it read aloud, and is the voice bearable? A book is eight to twelve hours of speech. A robotic voice doesn’t survive that.
• Where does your library live? Local files, a cloud folder, a vendor account, or a server you run.

The seven, compared

ReadEra: the safest free pick

Free, no ads, no account, and it opens almost anything, including Office documents and DjVu. The library is tidy and the reading view is calm. Read-aloud uses the Android system voice, and there’s no cross-device sync. If you just want to open EPUBs without thinking about it, install this and stop reading comparisons. Our detailed take: ReadEra vs Lectern.

Moon+ Reader: the most configurable

Fifteen years of features, and it shows in both directions. Almost every aspect of the page can be tuned, there are gestures and page-turn animations for everything, and Pro adds text-to-speech. The free version is ad-supported and the interface is dense. Great if configuring is part of the fun. See Moon+ Reader vs Lectern.

Librera: open source and endlessly adjustable

Similar philosophy to Moon+, but free and open source, available on F-Droid, and equally deep. Also reads Office formats and DjVu. The design is functional rather than beautiful, which many of its users consider a feature. See Librera vs Lectern.

KOReader: the typographer’s reader

Born on e-ink devices and ported to Android, KOReader has the most serious layout engine of the group: hyphenation dictionaries, per-book style tweaks, precise margins, and rendering that respects the book’s own CSS. The interface is utilitarian and read-aloud isn’t what it’s built for. If you own a Boox or a Kobo and care about how a page is set, it’s superb. See also our guide to reading apps on e-ink devices.

Kindle: only if your books are Amazon’s

The Kindle app is excellent at reading books bought from Amazon and poor at everything else. You can’t simply open an EPUB file from your phone’s storage; you send it to your Kindle library and Amazon converts it. Customisation is limited to a few presets, and read-aloud means buying the Audible edition. It’s a bookstore with a reader attached, and that’s fine if that’s what you want. More on that trade-off: Kindle vs EPUB.

PocketBook Reader: the library-loan specialist

Free, competent, and the answer to a specific question: it handles Adobe DRM, which is what most public libraries and many European ebook stores use. If your reading comes from a library app that hands you an .acsm file, this is the shortest route to actually reading it on Android.

Lectern: for people who also listen

We built Lectern because the readers above treat read-aloud as an afterthought. It ships two on-device neural engines, Piper and Kokoro, so a book can be narrated in a voice that holds up for a whole novel, with the current sentence highlighted so you can read along. It keeps the author’s typography (verse, drop caps, scene breaks), has one-tap presets instead of a settings maze, and syncs progress and highlights through a Drive, Dropbox, OneDrive or Nextcloud folder you already own, with no account on our side. It also opens PDF, MOBI, KF8, FB2, TXT and CBZ/CBR/CB7 comics.

Where it loses: it’s paid, there’s no free tier, it doesn’t read Office documents or DjVu, and it doesn’t support Adobe DRM, so library loans need PocketBook. If read-aloud doesn’t matter to you, ReadEra probably serves you just as well for nothing.

Pick by how you actually read

Whatever you pick, keep your books as files you own. Every app on this list can open a folder of EPUBs; only one of them can take your library away.
