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. Once your library mixes formats, a badge on each cover tells them apart.
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 or PDF 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, series or tag. Browse your covers like a real bookshelf. Keep your library in Calibre, Grimmory, BookOrbit or any cloud folder, and read on your iPhone. Your whole library, one tap away.
Discover thousands of free public domain books directly in the app. Project Gutenberg is built in, and you can add Standard Ebooks or any other OPDS catalog without leaving justRead.
Browse Gutenberg by category, sort it, and pick the language you read in. Download public domain classics with one tap, no browser needed.
Custom collections, tags, and saved filters let you slice your library any way you want. Create shelves by genre, mood, or reading status, or turn your folders into collections that fill themselves.
Jump to any letter with the alphabet bar, sort by 10+ criteria, and assign books to collections in bulk. Your library, your system.
Built for iOS from the ground up. Every interaction feels instant. Every animation is smooth. Every detail follows the design standards you're used to from the best apps on your device.
Quick actions, natural gestures, and thoughtful navigation make reading sessions feel effortless. Not because we cut corners, but because we didn't.
Switch fonts and adjust your layout without leaving the page. Jump between chapters with a full table of contents.
Search for any word or passage across the entire book in seconds. Highlight freely and bookmark as you go.
justRead.app takes full advantage of your iPad's larger display. Read in one column or two, set separately for portrait and landscape, so a page reads naturally, just like a real book.
Your library gets a sidebar with your collections and tags, Apple Pencil selects and highlights text, and a keyboard turns the pages. Statistics spread out into a wide grid of cards, so your habits and progress are all in view.
Adjust fonts, colors, margins, spacing, and alignment exactly how you prefer. Save different presets for day and night reading. Your perfect format, ready every time you open a book.
Import any font file and start reading with it immediately. Choose from every font on your device, OpenDyslexic and AccessibleDfA included, or add your own, then fine-tune weight and spacing for a look that is uniquely yours.
Read comfortably at night with dark themes that can invert a book's illustrations too. Adjust brightness from the side of the page without leaving your book, and let your themes switch by time of day or at sunset.
Effortlessly manage 5,000+ books without slowdowns. Search by author, series, title, or tags, and sort with 10+ criteria. Connect directly to a Calibre Content Server for two-way sync, or read your books from any cloud folder.
Slide along the Go to Page ruler, marked with your bookmarks and chapter starts, or jump to any chapter from the table of contents. Turn on the history strip to flip back to passages you have already read.
Track time read, pages, and reading speed with charts you can scrub and a heatmap of your year. Build streaks, unlock milestones from 10 to 730 days, and watch your habits improve over weeks and months.
Maximize your screen with true edge-to-edge reading that removes all distractions. Keep your screen awake and lock rotation so your reading angle stays exactly where you set it.
Protect your eyes with built-in 20-20-20 reminders that gently prompt you to look away every 20 minutes. Read for hours without strain, knowing your reading app is looking out for you.
Vote on upcoming features and suggest new ones directly inside the app. Every update is shaped by real reader feedback, so the app keeps getting better in the ways that matter to you.

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.
Finally a worthy successor to Marvin
Two-way sync with Calibre, a big tick on library metadata, and fast, helpful support. Forget the other e-reader apps, this is the one to go for.
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.
Your books, your way
Ridiculously customizable, works great with my Calibre library and OPDS, and syncs across devices. The developer has been amazingly responsive.
Exceptional app
A clean, uncluttered, modern interface, Calibre integration and excellent text-to-speech. Extra points for no telemetry or analytics.
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.
