Short answer: Choose Libby if you have a participating library card, ReadEra or PocketBook Reader if you already own EPUB or PDF files, and Kindle or Kobo Books if you want a commercial ebook ecosystem that syncs across devices.
There is an important distinction, however: a free reading app is not necessarily an app with a free book catalog. Some apps are free storefronts that sell most current books, some provide free access through a library, and others offer free stories with advertising or paid unlocks. The ranking below covers all four meanings of “free,” including conventional ebooks, personal files, library borrowing, classics, serialized fiction, and comics.
What “free reading app” actually means
Before downloading anything, identify which type of free access you want:
- Free app, commercial catalog: Kindle, Google Play Books, Apple Books, Kobo Books, and NOOK cost nothing to install, but many popular ebooks and audiobooks must be purchased separately or accessed through a paid service.
- Library borrowing: Libby and hoopla can provide ebooks, audiobooks, comics, and other media at no direct cost when your library participates and you have a valid card.
- Free reader for your own files: ReadEra, PocketBook Reader, FBReader, and Moon+ Reader are useful when you already have compatible EPUB, PDF, MOBI, or other files.
- Free, ad-supported, or freemium content: Wattpad, Inkitt, Serial Reader, and WEBTOON offer substantial free content, but may include advertising, premium chapters, subscriptions, or paid features.
Catalogs, prices, library participation, operating-system requirements, and free-title policies can change. This editorial ranking reflects official product pages and U.S. App Store or Google Play listings checked on August 10, 2026, rather than hands-on testing.

The 15 best free reading apps
1. Libby — best overall for library ebooks and audiobooks
Platforms: Android, iOS, and web. Eligible U.S. library ebooks may also be delivered to Kindle.
Libby is the strongest first choice for readers who have a participating public-library card. Depending on the library, you can borrow ebooks, audiobooks, magazines, and sometimes other digital materials, then download loans for offline use. Its catalog can include mainstream releases that would otherwise cost money.
The limitation is access, not the app itself. You need a card from a participating library, and each library controls its own collection, lending periods, hold queues, checkout limits, and Kindle compatibility. Availability also varies by country. Check your local library before assuming a particular title is included. Libby’s official U.S. App Store listing is available at Libby on the App Store.
2. Kindle — best for the broadest commercial ebook ecosystem
Platforms: Android, iOS, Fire, web, and desktop.
The Kindle app is free and supports adjustable text, notes, highlights, search, and dictionary tools. It is a good fit if you buy ebooks from Amazon, already own Kindle books, or want your reading position and library to follow you across supported devices.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Installing Kindle does not make Amazon’s entire catalog free. The app includes samples and selected free titles, while most current bestsellers are purchased separately or accessed through a paid program such as Kindle Unlimited. Libby can send eligible U.S. library ebooks to Kindle, but not every library, title, or country supports that delivery method. Amazon’s Kindle app guide explains the app’s core reading features.
3. Google Play Books — best for Google-account users and offline reading
Platforms: Android, iPhone, iPad, and web.
Google Play Books is convenient if your books, purchases, and Google account already live in the same ecosystem. The app supports ebooks and audiobooks, free titles and samples, and offline reading after a book has been downloaded. Google documents offline downloads for both Android and iOS.
It is primarily a free reading app, not a free commercial bookstore. Many books and audiobooks cost money, and the free catalog should be checked title by title. It can also be useful for reading compatible books you have already bought or otherwise obtained legally. See the Google Play Books listing for current platform details.
4. Apple Books — best for people already using Apple devices
Platforms: iPhone, iPad, Mac, and Apple Watch.
Apple Books is the most seamless option for readers who want a native Apple-device experience. The app provides free books, samples, and previews, while also serving as Apple’s storefront for paid ebooks and audiobooks. Apple states that Books has no subscription, but individual titles can still cost money.
The major drawback is platform lock-in: Apple Books is designed for Apple devices rather than Android or Windows continuity. It is a strong choice for free public-domain EPUB files as well as books purchased through Apple’s store. Visit Apple Books for the current platform and feature overview.
Rank #2
- 【Android Tablet】Equipped with the latest Android system, it has stronger compatibility, faster response speed and smoother operation. It is GMS certified, pre-installed with Google Play, and supports social applications such as Facebook, Twitter, YouTube, and TikTok. It is very suitable for watching videos, online chatting, reading e-books, etc.

In addition, the durable and environmentally friendly protective case can effectively protect your tablet from drops, scratches and dust. You can use it anywhere you want.
5. PocketBook Reader — best for many personal file formats
Platforms: Android and iOS.
PocketBook Reader is primarily a file reader rather than a large free-book storefront. It supports a broad selection of ebook and document formats, including EPUB, PDF, FB2, MOBI, DJVU, DOCX, RTF, TXT, comics, and audiobooks. Its iOS listing advertises 26 book and audio formats and Adobe DRM support.
Choose PocketBook when you want one flexible mobile reader for files from legitimate sources, supported catalogs, or cloud services. Do not expect the free download itself to unlock a large catalog of modern commercial books. The Android listing for PocketBook Reader provides current availability information.
6. ReadEra — best ad-free Android reader for files you already own
Platform verified: Android.
ReadEra is the clearest fit for Android users who want a straightforward offline reader without registration. Its Google Play listing describes the free version as ad-free, offline, without required in-app purchases, and capable of reading EPUB, PDF, MOBI/AZW3, DOC and DOCX, RTF, DJVU, FB2, TXT, ODT, CHM, and other formats.
Recommended Free Tools
Its limitation is its focus: ReadEra reads files you supply rather than acting as a major bookstore or subscription catalog. No iOS listing was verified in this research pass. If you download public-domain EPUBs or have a legally acquired personal library, ReadEra is one of the least complicated choices. Check the current ReadEra Google Play listing before installing.
7. Kobo Books — best Kindle alternative
Platforms: Android and iOS.
Kobo Books combines a free mobile app with Kobo’s ebook and audiobook store. It offers free samples and selected free titles, and it can sync reading across supported devices in the Kobo ecosystem. Kobo Plus is a separate subscription, and much of the broader store is paid.
Kobo is especially worth considering if you prefer an alternative to Amazon or expect to use Kobo hardware later. Its current help page lists Android 10 or later and iOS 18 or later, requirements that are unusually important to check before publication or installation because they can change. See Kobo’s current app requirements.
8. hoopla — best for library comics and mixed media
Platforms: Android and iOS.
hoopla is another library-based service, but its range extends beyond conventional ebooks. Participating libraries may offer ebooks, audiobooks, comics, manga, music, movies, and television programs. Audiobooks and music can support offline listening, and the Android listing highlights Android Auto support.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →You need a participating library account, and your library may impose monthly borrowing limits. The available catalog is therefore determined by the library rather than by hoopla alone. Add hoopla to Libby when your library supports both and you want comics, manga, or other media alongside books. The hoopla Google Play listing documents its current Android offering.
9. NOOK — best for Barnes & Noble users and free-title browsing
Platforms: Android and iOS.
The NOOK app is free and includes samples, syncing, ebooks, and audiobooks. Its current U.S. iOS listing states that the service offers more than 75,000 free ebooks and more than 10,000 free audiobooks. Because those figures and catalogs can change, treat them as dated listing information rather than a permanent guarantee.
Rank #3
- Our fastest Kindle Paperwhite ever – The next-generation 7“ Paperwhite display has a higher contrast ratio and 25% faster page turns.
- Ready for travel – The ultra-thin design has a larger glare-free screen so pages stay sharp no matter where you are.
- Escape into your books – Your Kindle doesn’t have social media, notifications, or other distracting apps.
- Battery life for your longest novel – A single charge via USB-C lasts up to 12 weeks.
- Read in any light – Adjust the display from white to amber to read in bright sunlight or in the dark.
The broader NOOK catalog is commercial. New digital content is generally purchased through the Barnes & Noble website and then synchronized to the app rather than bought directly inside the app. NOOK is most sensible for readers who already use Barnes & Noble or want to browse its dedicated free-title inventory. Check the current NOOK App Store listing.
10. FBReader — best for cross-platform personal libraries
Platforms: Android, iOS, Windows, macOS, Linux, and ChromeOS.
FBReader is a useful choice when you move between a phone, tablet, and computer. Its free reader tier supports formats including EPUB, FB2, MOBI/AZW3, HTML, RTF, DOC, plain text, and Readium LCP ebooks.
The free tier is not identical on every platform. The current iOS version caps the library at ten books and disables online translation; premium removes or expands some restrictions. The iOS page lists version 1.2.6, published February 26, 2026, with iOS/iPadOS 13 or later compatibility. Review the FBReader iOS information if those limits matter to you.
11. Moon+ Reader — best for Android power users
Platform verified: Android.
Moon+ Reader offers unusually deep control over formatting, gestures, themes, navigation, and reading behavior. It supports EPUB, PDF, DJVU, AZW3, MOBI, FB2, CBZ/CBR comics, DOCX, ODT, RTF, TXT, HTML, OPDS, and more, along with local files and online libraries.
The free version contains ads and the app offers in-app purchases. Moon+ Reader Pro adds features such as ad removal, text-to-speech, statistics, additional themes, and other controls. It is a better fit for someone who wants to customize nearly every aspect of reading than for someone seeking a simple, completely ad-free experience. See the Moon+ Reader Google Play page.

Platforms: Android and iOS.
Wattpad is not a conventional bookstore reader. It is a social-fiction platform with millions of stories, including original fiction, romance, fanfiction, and user-published serials. Readers can build lists, comment, discover recommendations, and read supported content offline.
The service contains advertising and in-app purchases, and some stories or features may be premium. It is therefore “free” in the sense of offering a large amount of no-cost reading, not in the sense that every story and feature is unrestricted. The Android listing was updated June 4, 2026, so verify current availability and policies at publication. The Wattpad App Store listing describes its reading and writing community.
13. Inkitt — best for free indie novels
Platforms: Android and iOS.
Inkitt focuses on free novels from independent and emerging authors. It offers genre discovery, recommendations, customizable reading settings, and offline reading. Readers looking for new romance, fantasy, mystery, or other genre fiction may find it more focused than a general ebook storefront.
Rank #4

Its catalog is primarily English-language fiction and should not be treated as equivalent to a mainstream-publisher ebook store. Availability is also dependent on the platform and service catalog. Inkitt confirms free apps through both the iTunes App Store and Google Play; the iOS listing is a useful starting point.
14. Serial Reader — best for a daily classics habit
Platforms: iOS and Android.
Serial Reader turns public-domain classics into daily issues designed to take roughly 20 minutes to read. Instead of confronting a long novel all at once, you receive a scheduled installment, making the app a practical tool for building a consistent reading habit.
The free tier covers hundreds of classics. Official listings differ on the exact catalog count, so a precise number should not be treated as permanent. Premium features include options such as early access, cross-device sync, notes, read-later storage, and delivery controls. See Serial Reader’s Android page for current details.
15. WEBTOON — best for free webcomics, manga, and manhwa
Platforms: Android and iOS.
WEBTOON is the best fit on this list for visual serials rather than traditional ebooks. Millions of episodes are available free, and ongoing Originals are released weekly. The service covers webcomics, manga, manhwa, romance, fantasy, action, and other illustrated genres.
Free access is not universal across every release schedule. Coins can unlock early or premium episodes, while some series use Ad Pass, in which a short advertisement temporarily unlocks an episode. WEBTOON is free to download and use, but it is monetized. Its official free-app explanation describes these distinctions.

How to read free public-domain ebooks
Project Gutenberg is a content source rather than a reading app. Its official guidance says it offers more than 75,000 free ebooks, supports browser reading and downloads, and does not have an official app.
- Open Project Gutenberg in a browser and find a title that is public domain in your country.
- Download a format supported by your device, usually EPUB for reflowable text or plain text for maximum compatibility.
- Open or import the file into Apple Books, Kindle, PocketBook Reader, ReadEra, Moon+ Reader, or another compatible reader.
- Check the copyright status where you live. Public-domain status can vary by country, and a book being free on Project Gutenberg does not make every edition or translation free to redistribute.
This route is particularly useful when you want genuinely free classics without ads, coins, library holds, or a subscription. Project Gutenberg specifically recommends compatible reading apps rather than claiming to provide its own official mobile app.
Do you need a dedicated e-reader?
No. Every app above can be used on a compatible phone, tablet, or computer, and buying hardware is not required to access free reading. A dedicated E Ink reader can nevertheless reduce distractions, improve long reading sessions, and extend battery life.
Optional hardware by reader type
- Kindle Paperwhite: A natural companion for Kindle users and eligible U.S. Libby loans delivered to Kindle. Amazon identifies the Kindle Paperwhite 12th Generation as a 2024 model with adjustable warm light, IPX8 waterproofing, dark mode, VoiceView, 16GB storage, and up to 12 weeks of battery life. Those are manufacturer-documented specifications, not a personal-use claim. Library delivery remains subject to title, library, and country eligibility.
- Kobo Clara BW and other Kobo e-readers: A relevant alternative for Kobo Books users. Kobo’s device pages describe glare-free E Ink, adjustable front lighting, weeks of battery life, broad ebook-format support, and a Clara BW model with waterproofing and dark mode. Library behavior is not identical in every market, so confirm local support.
- BOOX Page: The more specialized option for advanced Android users who want to install multiple reading apps on an E Ink device. BOOX describes it as using open Android 11 and supporting third-party apps. That flexibility also makes it a more technical purchase than a closed Kindle or Kobo reader.
For audiobook users, Bluetooth headphones for audiobook listening are a more relevant accessory than an e-reader. Libby, hoopla, Kobo, and NOOK all have audiobook-related use cases, although exact playback features and title availability depend on the service and catalog.

Platform, country, and compatibility checks
The listings used for this ranking include U.S. storefront pages and official global developer pages. Your results may differ because of country, library participation, copyright rules, storefront availability, and operating-system version.
- Kobo’s current help page lists Android 10 or later and iOS 18 or later.
- FBReader’s current iOS page lists iOS/iPadOS 13 or later.
- PocketBook’s iOS information lists iOS 13 or later.
- NOOK’s current iOS listing requires iOS 16 or later.
These requirements are volatile. Check the app’s store listing immediately before installation, especially on an older phone or tablet. Also check whether your public library supports Libby, hoopla, Kindle delivery, or the specific title you want.
Frequently Asked Questions
What is the best completely free reading app?
For an Android user who already has legally obtained EPUB, PDF, or other supported files, ReadEra is the clearest no-registration, offline, ad-free option identified in this research. For free access to mainstream ebooks, Libby is usually better—but it requires a participating library card and the title must be available through that library.
Are Kindle, Apple Books, Kobo, and Google Play Books free?
The apps are free to download, but their catalogs are not entirely free. They include samples and selected free books while also selling ebooks and audiobooks. Installing the app does not provide unrestricted access to current bestsellers.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can I use Libby without a library card?
Generally, no. Libby requires a valid card from a participating library or library system. Catalogs, holds, lending periods, and Kindle delivery vary by library and country.
Does Project Gutenberg have an official app?
No. Project Gutenberg is a website and ebook source. It offers browser reading and downloadable formats, which you can open in compatible apps such as Apple Books, Kindle, PocketBook Reader, ReadEra, or Moon+ Reader.
Which free reading app is best for comics?
Use hoopla if your participating library offers comics or manga, or WEBTOON for webcomics, manga, and manhwa. WEBTOON has free episodes but also uses paid coins, early access, and, for some series, temporary Ad Pass unlocking.
The Bottom Line
Best overall: Libby for library access. Best for your own files: ReadEra on Android or PocketBook Reader across Android and iOS. Best commercial ecosystem: Kindle, with Kobo as the main alternative. Best for classics: Serial Reader or Project Gutenberg plus a compatible reader. Best for serialized fiction and comics: Wattpad, Inkitt, or WEBTOON. Recheck app availability, pricing, library participation, catalogs, and operating-system requirements before choosing.
