EPUB, PDF, comics, and audiobooks in one native iOS reader. Fast, deeply customizable, and built to disappear so you can simply read. FOUR FORMATS, ONE SHELF Read EPUB 3 and PDF. Read CBZ and CBR comics and manga, with two-page spreads, double-tap zoom, and a reading direction you set per book. Listen to audiobooks with chapters, a sleep timer, Car Mode, and CarPlay. Or follow along with EPUB 3 narration, where the text highlights in time with the voice. READ ALOUD Any book can be read to you, by any Apple voice on your device or by natural neural voices in 31 languages that you download once and then run offline. The sentence highlights as it is spoken and the pages turn on their own, with speed presets, sentence skips, a sleep timer, and Lock Screen controls. Prepare a book in advance and keep listening with the screen off. TYPOGRAPHY YOU CONTROL 200+ fonts, or import your own. Tune size, weight, line and paragraph spacing, alignment, hyphenation, and separate margins for portrait and landscape. Save settings per book so a novel, a textbook, and poetry each look right. Build your own color themes and let them switch at sunset. Choose which buttons the reader toolbar shows and where a tap opens it, and give links their own color and style. Smart dark mode keeps images natural, and in-reader brightness, Line Focus, and eye-care break reminders protect your eyes. NO LOCK-IN, EVER Your books stay ordinary files in an ordinary folder, never a proprietary database. Point justread at any folder: on device, iCloud Drive, or one your cloud app syncs through Files. Import from a Calibre server or any OPDS catalog. Email a book to your Kindle or PocketBook. IN SYNC WITH YOUR E-READER Your reading position follows you to any e-reader running KOReader, a Kobo included, in both directions. Connect a self-hosted Grimmory server to browse and download its books, send books to it, and keep status, ratings, highlights, notes, and bookmarks in step both ways. A LIBRARY THAT SCALES Thousands of books with no lag, and a book opens in about a second. Instant search by title, author, or series. Automatic metadata and series detection, 11 sort modes, saved filters, collections, and tags. Edit any book's details by hand, description included. Spotlight opens any book from your home screen. HIGHLIGHTS, NOTES, BOOKMARKS Highlight, underline, and attach a note. Browse every highlight across your whole library in one place, share a quote as a card, or export to Markdown, PDF, or Readwise. YOUR READING, IN NUMBERS Daily goals, a yearly books goal, streaks, and milestone badges. An hourly heatmap shows when you read best. Monthly and yearly recaps, plus a story-style Reading Wrap that turns your year into cards worth sharing. AND THE REST Home screen and lock screen widgets. Dictionary and translation. Full-text search and a nested table of contents. iCloud sync, so you resume on the exact line on any device. Right-to-left and Japanese vertical text. A page curl, if you want one.
