The 4 Best Apps for Reading Books in 2026
The phone in your pocket is also an endless library: millions of ebooks a tap away, your exact page synced across devices, and text as large as your eyes need. The app you pick matters, because each one ties you (or doesn't) to its ecosystem. In this guide we compare the 4 best apps for reading books in 2026.

Google Play Books takes your own ePub and PDF files alongside its store, with no subscription: the freest option for a library built from several sources.
Google Play Libros is Google's bookstore, with one clear advantage over Kindle: it takes your own ePub and PDF files, uploads them to your library and syncs them across devices. You buy books and audiobooks outright, with no subscription required and the usual Play Store deals. The most flexible option if your books come from several places.
Pros
- Reads your own ePub and PDF files
- No subscription: you buy only what you want
- Audiobooks built in
Cons
- Smaller catalogue than Amazon on exclusives
- No e-reader of its own like the Kindle
- Limited social features

Kobo backs the standard ePub format with a large catalogue and its own e-readers: the serious alternative to Amazon.
Kobo, from Rakuten, is the big alternative to Kindle: millions of ebooks and audiobooks in the standard ePub format (the one used by almost every bookshop in the world), with its own line of e-readers. Its Rakuten points scheme and frequent promotions make it appealing for heavy readers who don't want to be tied to Amazon.
Pros
- Standard, open ePub format
- Large catalogue of ebooks and audiobooks
- Ecosystem of Kobo e-readers
Cons
- Less well known in Spain than Kindle
- Somewhat smaller Spanish-language catalogue

TopApps analysis
Everand offers unlimited ebooks, audiobooks and magazines for a monthly fee: the streaming model applied to reading, for people who devour books.
Everand (formerly Scribd) is the Netflix of reading: one monthly subscription gets you a huge catalogue of ebooks, audiobooks, magazines and podcasts without buying title by title. Ideal for anyone who gets through several books a month, for whom the flat rate works out far cheaper than buying each one.
Pros
- Flat rate: ebooks + audiobooks + magazines
- Pays off if you read 2 or more books a month
- Varied catalogue, Spanish titles included
Cons
- No access without a subscription
- Some bestsellers take a while to arrive
- The catalogue rotates over time
Frequently asked questions
Doesn't reading on a phone strain your eyes?
More than an e-ink reader, yes; less than people assume if you set it up properly: turn on dark mode or the sepia background, drop the brightness at night (or use your system's warm-light filter) and raise the font size without embarrassment. For long daily sessions a Kindle or Kobo e-reader is still the better buy; for reading in gaps (commutes, waiting rooms, bed), the phone is more than enough.
Kindle or Google Play Books?
Kindle if you want the biggest catalogue, the daily deals and the option to move to an e-reader while keeping your library. Google Play Books if you value freedom: read the ePubs you already own from other stores or from your public library, without locking yourself into a closed ecosystem. Everything else (notes, dictionary, syncing) is a tie. Plenty of readers end up with both: Kindle to buy, Play Books for everything else.
Is a subscription like Everand or Kindle Unlimited worth it?
Do the maths: if you read two or more books a month from the included catalogue, a flat monthly fee of roughly $10-12 beats buying them. The catch is the catalogue: new releases and big-publisher bestsellers often arrive late or never, so it works better for genre readers (romance, thriller, fantasy) and backlist browsers than for people chasing new titles.
