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.

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.

Read full description

Read with your eyes, your ears, or both at once. Biblio is your library for books, podcasts, videos, photos and your own files. Text and audio run together: the highlighted word shows where you are, and when you look away, you keep listening from the same spot. WHAT YOU WILL FIND IN BIBLIO - Synchronized reading: text and audio at the same time, with the current word highlighted. - Free classics of world literature from Project Gutenberg and the Czech National Digital Library, with covers and edition details. - Podcasts and YouTube channels: subscribe, and new episodes and videos arrive in your library on their own. - Your own files: EPUB, PDF, audiobooks, songs from your Music library, videos, photos and scanned pages. Your recordings and videos can be transcribed into text. - Photos and albums: a viewer with captions, automatic photo descriptions and video summaries. - Presentations: combine photos, videos, music, captions and passages from books into your own story, play it, even on your TV via AirPlay, or export it as a video. - The Librarian: ask what to read next. It finds, adds and downloads. - A reader with your choice of font, size and colors, a progress indicator and read-aloud with your device's voice. - Wherever you are: iPhone, iPad, Mac, CarPlay and Apple Watch. Your reading position syncs through iCloud. FOR EVERYONE Biblio is built for sighted and blind readers alike.
