Best reading apps in 2026

To read free ebooks from your local library, use Libby with a library card. For books you buy, Kindle or Apple Books keep your library in sync. For files you already have, EPUB, PDF or FB2, PocketBook Reader is a free reader without ads. Full breakdown, and new reading apps worth a look, below.

How we picked: a reading app does one of two jobs, it is either a store or library that gives you books, or a reader that opens files you already have. We checked each app’s own store description for where its books come from, which file formats it opens, what is free and whether it works offline, then added a separate section for new reading apps surfaced by real visit traffic from the Censuus ranking.

Can you read books for free in an app?

Yes, in two honest ways. Libby lets you borrow ebooks, audiobooks and magazines from your local library for free with a library card. And a free reader such as PocketBook Reader opens books you already own or downloaded legally, in EPUB, PDF, FB2 and more, without ads.

Store app or reader app?

A store app (Kindle, Apple Books) is the easy path when you buy books there: purchases appear on every device and your place syncs. A reader app is for everything else: files from other stores, PDFs for work, old FB2 collections. Many people keep one of each.
