The story behind justRead
My son and I spent six months building the EPUB reader we always wanted.

Novels, work PDFs, comics and audiobooks usually mean four apps, four libraries, and four places your progress goes to die. Here they share a library, a search box, and one streak for all of it.
EPUB and PDF keep your typography and your place. Comics get a panel of their own, with double-tap zoom and thumbnails. Audiobooks play from one m4b, mp3 or flac, or from a folder of chapters stitched into a single book, cover and chapter list included. Every cover gets a format badge.
Tired of one-size-fits-all ebook readers? JustRead.app puts complete control in your hands. Customize everything - from typography and colors to spacing and layout, and much more - to create the perfect reading environment tailored to your preferences.
Whether you prefer larger fonts and wider spacing, night mode with specific color schemes, or custom fonts that inspire you, JustRead.app adapts to match your unique reading style. No compromises. No limitations.
Most apps sell you the audiobook a second time, in a second app. Here any EPUB you own reads itself to you, from the line where your eyes stopped. Words light up as they're spoken and the pages turn themselves.
Use an Apple voice, or download a natural one that runs on the phone itself. No account, no server, no signal. Set the speed and the sleep timer, lock the screen, and it keeps going. Audiobooks you already own sit in the same library, under the same bookmarks and stats.
Reading trackers make you do the tracking: finish a chapter, open another app, guess at the pages. justRead.app is the reader, so there's nothing to log. Open a book and the clock starts; close it and the session is saved.
A streak off real days, a heatmap of the year, your pace per book, and an honest answer to how long the one on your nightstand will take. Work PDFs count, comics count, so does the audiobook you had on during a walk, and it all comes back as a Recap every week, month and year.
A library worth reading deserves a reader worth using. JustRead.app keeps thousands of books organized and instantly accessible. No lag, no clutter, no endless scrolling to find what you want.
Search by title, author, or series. Browse your covers like a real bookshelf. Manage everything in Calibre on your Mac or PC, sync through the cloud, and read on your iPhone. Your whole library, one tap away.
Discover thousands of free public domain books directly in the app with built-in OPDS catalog support. Browse Project Gutenberg, Standard Ebooks, and more without leaving justRead.

Fantastic eReader
Best app I've found for syncing with Calibre. Customization rivals the great Marvin app, with superior library management.
Best book app
One of the best apps for books. My EPUBs, PDFs and even my audiobooks all live here, with yearly goals and monthly wraps.
Calibre users rejoice
A great reading experience on every device, with true two-way sync to my Calibre server, and a roadmap the community votes on.
Great native reader
The first app that really nails library management. It syncs metadata over iCloud, and it is the only one that gets series right.
Amazing app, unparalleled support
I tried Kindle, Apple Books and Book Fusion, and each lacked something. This has it all, and the developer ships what we ask for.
The best reader on the App Store
Absolute control of customization. Custom font support. The ability to vote on next features and development.
My new mobile happy place
A beautifully made reader app. Love the statistics and how it works with my 5,000+ book library and cloud storage.
Comprehensive epub reader for iOS
Finally an app that manages a book collection and acts as a fully functional reader. Streams from Dropbox without using phone storage.
Free readers exist. You've tried them. Here's what you've been missing.
With Kindle and Apple Books, your library lives on their servers, under their rules. Delete the app, lose everything.
JustRead reads your EPUBs and PDFs directly. Your files, your cloud, your control. No DRM walls. No ecosystem traps. Switch apps or devices whenever you want, your books stay yours.
Most reading apps give you two fonts and a dark mode toggle. Your reading experience shouldn't feel like everyone else's.
Custom fonts, precise typography controls, your color schemes, your layout. Built natively for iOS, every swipe, every animation, every detail crafted to feel exactly right on your iPhone.
You finish a book and... nothing. No record of when you read, how long it took, or how your habits are growing.
Track your reading streaks, pace, and progress. See your reading calendar, earn achievements, and watch your habits transform over time. Reading becomes not just a hobby, but a practice you can see improving.
