RookReader
Read full descriptionHide full description
You don't just read. You disappear into books. RookReader is built for that. Beautiful typography, immersive themes, nothing standing between you and the story. EVERY BOOK. ONE APP. EPUBs, PDFs, comics, web serials, whatever format it arrives in. Pull them from Files, iCloud Drive, Google Drive, Dropbox, Calibre-Web or any free catalog. One shelf for everything you own, sorted into collections and smart shelves that fill themselves. Don't own it yet? Scan the barcode or paste a link and it waits on your Want to read list until the file is real. Out of books? Over 20,000 audiobooks are already inside, free. MEET ROOK AI Forgot who that character is? Lost the thread three chapters back? Just ask. Rook AI has read every page you have and not one page more. Zero spoilers, ever. It catches you up, explains what just happened, and still remembers the character introduced 200 chapters ago. Bring your own key (Claude, OpenAI or any compatible provider) so your books stay between you and your provider. READING THAT FEELS LIKE READING • Eight reader themes, from crisp white to warm sepia to true black • Your font, size, spacing and margins, saved as profiles you switch in a tap. Import your own typefaces too • Turn pages by swipe, scroll or tap, wherever your thumb already rests • Auto-scroll that flows at your pace, so you never lift a finger • Bionic reading bolds the start of each word so your eyes glide instead of grind • Speed reading feeds you one word at a time when you want to move • Ambient rain, cafe hum and cinematic calm playing under the page • Vertical text for CJK, and clean-up for curly quotes and ALL-CAPS shouting "WAIT, WHERE WAS THAT SCENE?" You remember the moment, not the page. Describe it, like "they argued on the rooftop in the rain", and RookReader jumps you straight to it. Can't recall which book? Search your whole library at once. LISTEN INSTEAD Have any book read aloud, or bring your own audiobooks in. Real chapters, sleep timer, lock screen controls. Own both formats? Switch between reading and listening and pick up in the same spot. KEEP EVERY LINE YOU LOVED Highlight it, note it, tag it, and actually keep it. Your Notebook searches every highlight and note across your whole library at once. Export to Markdown or Readwise, or turn a line into a quote card worth sharing. Switching from another reader? Bring your highlights with you. EVERY WORD, EVERY NAME Hard words get a plain-English hint right above them, no flow broken. Look one up enough times and it lands in your vocabulary deck for review. Offline dictionary and translation are built in. Too many invented names to track? Write your own glossary entry once and RookReader reminds you every time it reappears. ONE ACCOUNT. EVERY DEVICE. iPhone, iPad, and every other device you read on all pull from the same shelf. Your library, collections and reading stats follow you everywhere, free — and so does your place in one book, so you can watch sync work before you pay for it. Go Pro and your exact page, every highlight and every note sync too, on every book, quietly in the background. KOReader users can sync positions as well. A READING HABIT YOU CAN SEE Streaks, minutes, books finished, and a year in reading worth showing off. Commit to a finish-by date and get tonight's page count. Close the last page of a book and the next one in the series is already waiting. OWN IT. DON'T RENT IT. Pay once. That's it, forever. No subscription creeping onto your card. No features locked away next year. Just a reading app that's actually yours, for less than a coffee.

Understand difficult books as you read. Tap a word to see what it means in its sentence, or select a passage for a short, plain explanation, without leaving the page. ReadSense is an EPUB reader for books that fight back: classics, dense literary fiction, old or unusual language. When a word or a sentence stops you, you don't leave the book to search. You touch the text. TAP A WORD Get the one meaning it has in this sentence, not a list of ten, with how to say it. Old spellings, dialect, fixed phrases and familiar words that once meant something else are read for what they mean here. SELECT A PASSAGE Hold a word to take its sentence, or hold and drag to choose a passage. A short, plain explanation appears on the page, never over the words you selected: what a tangled sentence says, who is speaking, what an allusion points to. NO SPOILERS Explanations use only what you've read so far. Nothing past the paragraph you're reading is ever sent. FREE BOOKS INSIDE More than a thousand classics are in the app, free to get and free to read: novels, plays, poems, mysteries, philosophy, children's books. Each one says what it is and how it begins before you choose it. Or bring your own. A READER THAT STAYS OUT OF THE WAY • Free classics inside, and your own EPUB files (DRM-free) from Files or another app • Pages turned by swiping, with two pages side by side on a large iPad • Search inside the book, bookmarks, Contents and footnotes • Two typefaces, line spacing, margins, three themes and text that goes very large • Pictures, lists and code shown as the book has them • Your place is kept in every book • Works with VoiceOver and larger text • No account, no ads, no tracking HOW ANSWERS ARE MADE To explain a word or passage, ReadSense sends the text you select and surrounding text from the same chapter to an outside AI provider, which writes the answer. ReadSense doesn't save that text or the answer, and you are asked before anything is sent. Your books stay on your device. Explanations are written by AI and can be wrong; they are a reading aid. FREE TO TRY ReadSense is free to download. The books inside are free, and reading is always free, your own books included. You can try lookups free; after that, a monthly or annual subscription keeps the answers coming. Subscriptions renew automatically until cancelled; you can cancel anytime in your Apple Account settings.
