15 Best Book Apps for iPhone for Readers Who Buy Books and Never Finish Them

Most iPhones already have two or three reading apps sitting on a home screen somewhere, downloaded with good intentions and rarely opened again. According to a Pew Research Center survey, 31% of Americans read an e-book in the past year, nearly double the 17% who said the same in 2011, with smartphones now the primary device used by most digital readers.

That's the strange part. The phone most likely to pull your attention away from reading is also the best portable reading device most of us own. This guide breaks down the 15 best book apps for iPhone by exactly what you want to do with them. 

And if you want to take your reading routine one step further, try Headway for learning key ideas from top nonfiction books in a few focused minutes.

How to pick the right book app before downloading all 15 of them

If you already have two or three book apps for iPhone sitting unused on your phone, you're not alone. Finding the best book app for iPhone is all about asking three honest questions about how you read:

• Where do your books come from? Amazon purchases, library loans, your own EPUB or PDF files, or nonfiction you want summarized. 

• Do you read text, listen to audio, or switch between both depending on the moment? 

• And do you want to track every book you finish, or just read without the extra bookkeeping?

Kindle and Headway: The best book app for iPhone options readers reach for first

Before getting into every category, two apps come up more than any others when people ask for a reader app iPhone recommendation to put on their home screen. One is for buying and owning books. The other is for learning from them without reading them cover to cover.

1. Amazon Kindle

Kindle is the default for most U.S. readers, not because it's the best-designed app, but because Amazon is where most people already buy their books. Whispersync keeps your place synced between the Audible audiobook and the Kindle text version, so switching from listening on a walk to reading on the couch feels seamless. 

You also get cross-device progress sync, the Bookerly font built for screens, optional Kindle Unlimited access, and X-Ray for quick character or term lookups. The one catch: you can't buy books directly inside the iOS app anymore, only through a browser, thanks to Apple's in-app purchase rules.

Best for: Readers already buying from Amazon, Kindle Unlimited subscribers, and commuters who switch between audio and text. 

Cost: Free app; content purchased separately or via Kindle Unlimited at $11.99 a month.

2. Headway

Headway is built for readers who want the ideas from a nonfiction book without committing three weeks to reading it cover to cover. Summaries run about 15 minutes in either text or audio, pulled from a library of 2,500+ bestselling nonfiction titles.

Growth plans organize content around specific goals like productivity, relationships, career, or health, and daily insights arrive as short lessons you can fit between meetings. 

Add in reading streaks, progress tracking, spaced repetition flashcards for retention, and offline access, and it becomes less of the best app to read books on iPhone and more of a daily habit. 

Headway also works on Apple CarPlay and Android Auto, so a commute counts as learning time too. Many readers use it to preview a book's core ideas before deciding whether to buy the full version, or simply to swap fifteen minutes of scrolling for fifteen minutes of something that sticks.

Best for: Busy professionals, self-improvement readers, and anyone who wants nonfiction insights without the time commitment of a full book. 

Cost: 7-day free trial available; Premium subscription for $19.99/month.

Download the Headway app on the App Store to access summaries of the world’s bestselling nonfiction books by your favorite authors and celebrities.

Best ebook reader apps for iPhone: Buying and owning your library

Beyond Kindle, two more picks round out the search for the best reading apps for iPhone for readers who buy their books outright and want a clean place to keep them.

3. Apple Books

Apple Books requires zero setup. It's synced with your Apple ID from the moment you open it, and it feels like part of iOS rather than something bolted on. The page-curl animation, automatic dark mode sync, and the ability to import EPUB files straight from Safari make it a genuinely easy iPhone book reader for casual use. 

Font options include San Francisco and Palatino, and Apple Pay handles purchases in two taps. The trade-off is a smaller store selection than Kindle and no reading outside Apple devices.

Best for: Minimalists and casual readers who want to open an app and read without configuring anything. 

Cost: Free to download; content purchased à la carte.

4. Kobo

Kobo is the answer for readers who want a bookstore without being locked into Amazon or Apple. It integrates deeply with Libby, so you can borrow library books from inside Kobo Books itself, and it supports a wide range of formats: EPUB, MOBI, PDF, and CBZ for comic books. 

The Kobo Plus subscription is optional, and typography customization goes further than Apple Books allows. It also runs on Android and desktop, which makes it more portable across devices than a lot of the competition.

Best for: Readers who want a polished store experience outside Amazon's ecosystem and anyone who borrows from the library often. 

Cost: Free app; content purchased à la carte or via Kobo Plus at $7.99 a month.

Best free reading apps for iPhone: A full library with no subscription required

"Free" means different things depending on which free iPhone reading app you explore. Some are free to download, some are free to borrow with a library card, and one is free with no strings attached at all.

5. Libby by OverDrive

Libby is the main app for borrowing ebooks and audiobooks from U.S. public libraries. Log in with your library card, place a hold on a title, and it downloads automatically once available. 

Loans return themselves when the lending period ends, so there's nothing to remember and no late fees. The interface is clean, and the "Open in Kindle" option lets you borrow through Libby but actually read inside the Kindle app if you prefer. The only real friction is that popular new releases often have waitlists.

Best for: Anyone with a library card who wants to pay nothing for books over the long run. 

Cost: Free; requires a library card from a participating library system.

6. Hoopla

Hoopla solves the one problem Libby has: waiting. There are no holds and no waitlists. Borrow instantly from a catalog of more than 13 million titles that includes comics, manga, audiobooks, and films. 

Each library sets its own monthly borrowing limit, usually somewhere between 5 and 15 items, and Hoopla is available at many of the same library systems as Libby.

Best for: Readers who want instant access without waiting, especially for comic books or audiobooks.

Cost: Free; requires a library card from a participating library.

7. Project Gutenberg

Project Gutenberg is a different kind of free entirely. It's not for new releases. It's for readers who want Austen, Dickens, or Dostoyevsky without paying a cent or creating an account. 

The catalog covers more than 70,000 public domain titles, downloadable in EPUB, Kindle, or HTML format, and you can import files directly into other apps to read books on an iPhone.

Best for: Readers of classic literature who want zero cost and no setup. 

Cost: Completely free.

Best audiobook apps for iPhone: for readers who prefer listening

Audiobooks aren't a fallback for people too busy to read text. They're a format choice, and the commute, gym, and kitchen are three places where listening usually wins.

8. Audible

Audible is the dominant audiobook platform in the U.S., with the largest catalog, the highest production quality, and Whispersync integration with Kindle so you can switch between listening and reading mid-book. 

The credit-based model gives you one credit per month for one audiobook, and anything you purchase stays in your library permanently, even if you cancel later.

Best for: Dedicated audiobook listeners who want premium narration and the widest selection. 

Cost: Free app; $14.95 a month for one credit, or à la carte purchases.

9. Speechify

Speechify isn't a traditional audiobook app. It's a reader-to-audio converter. It can narrate PDFs, web articles, Google Docs, or books you already own using AI-generated voices at speeds up to 4.5x. 

There's also an OCR feature that reads physical pages through your camera. This is a supplement to your reading, not a replacement for a curated catalog like Audible's.

Best for: Speed readers, people with dyslexia or reading difficulties, and anyone who wants documents and articles read aloud. 

Cost: Free tier available; premium starts around $139 a year.

10. Libro.fm

Libro.fm works like Audible with one key difference: every purchase sends money to an independent bookstore of your choosing. It runs on the same one-credit-per-month model, with each credit good for one audiobook from a catalog of more than 600,000 titles. 

Downloads are DRM-free, so files stay yours to keep even if you cancel, and members get 30% off any additional à la carte purchases. An annual plan bundles 12 credits for $169.99 per year, which works out cheaper than paying month-to-month.

Best for: Audiobook listeners who want their subscription to support a local bookstore instead of a large retailer. 

Cost: $14.99 a month for one credit, or $169.99 a year for 12 credits.

More apps for learning from nonfiction books on iPhone

Beyond Headway, two more apps take a similar approach to condensing nonfiction, just with different trade-offs on library size and structure.

11. Blinkist

Blinkist works in a similar format to Headway: nonfiction books condensed into roughly 15-minute summaries called "Blinks," available in text and audio. The library is larger, with more than 7,500 titles across categories like business, psychology, and productivity, and every title includes professional narration. 

The free plan gives you one preselected "Daily Blink" a day with no audio and no choice of title. Premium unlocks the full library and typically runs about $99.99 a year, or roughly $15.99 a month if billed monthly.

Best for: Readers who want the widest possible library of nonfiction summaries and don't mind a more passive, read-it-and-move-on format. 

Cost: Free tier with one Daily Blink; Premium at approximately $99.99 a year.

12. Everand (formerly Scribd)

Everand is a subscription library covering ebooks, audiobooks, magazines, and user-uploaded documents. Access is largely unlimited, though very high-demand titles sometimes have limits. It's a good fit for readers who want variety across formats without buying individual titles one at a time.

Best for: Heavy readers who want one subscription covering ebooks, audiobooks, and magazines. 

Cost: Free trial available; approximately $11.99 a month.

📘 Choose retention over just browsing with Headway!

Best apps for tracking your reading and discovering what to read next

Reading apps and reading tracker apps do completely different jobs. For some readers, the tracker is the actual habit, not the app they read inside.

13. Goodreads

Goodreads, owned by Amazon, is still the most-used book social network. It offers "Want to Read" shelves, an annual reading goal challenge, a friend activity feed, author pages, and reviews. 

The community is enormous, which makes it genuinely useful for finding recommendations. The trade-off is a slow app with a dated interface, and some readers aren't thrilled about the Amazon ownership.

Best for: Social readers who want a community, annual goal tracking, and book discovery through friends and ratings. 

Cost: Free.

14. StoryGraph

StoryGraph is the analytics-first alternative to Goodreads. It offers mood-based filtering, reading pace tracking, detailed genre and theme statistics, diverse author tracking, and independence from Amazon entirely. It's mobile-first and noticeably cleaner than Goodreads.

Best for: Data-driven readers who want detailed reading statistics without social pressure. 

Cost: Free with an optional premium tier.

15. Literal

Literal is the newest name in this category: minimal design, a clean mobile interface, book clubs, an activity feed, and an easy import option from Goodreads. It's the pick for readers who find Goodreads a bit much.

Best for: Readers who want simple tracking with a clean interface and optional social features. 

Cost: Free.
