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.

Trace Reader is a private, unofficial reader for AO3 EPUBs. Import a story and read it comfortably offline, with the metadata and organisation fanfiction readers actually need. I built this for accessible reading tailored to offline AO3 reading because Apple Books wasn't quite enough. Choose paged or continuous scrolling, adjust the type and spacing, and read in Paper, Sepia, Night or High Contrast themes, with accessible fonts. Filter your collection with all of AO3's filters, and view your library by the things that matter for fanfiction: reading status, fandom, tags, and ships. NO AO3 LOGIN - Keep your account details private. You should never trust a third party with your AO3 login details and this app will never ask you for them. BUILD A LIBRARY THAT FEELS LIKE YOURS • Keep stories as Saved, Reading, Paused, Caught up, Finished or Dropped • Add ratings, personal tags, highlights, and notes by story, chapter or highlighted passage. • Search and filter by fandom, relationships, characters, warnings, series and more • Import individual EPUBs or choose a folder that will automatically load EPUBs once you download them from AO3. • Keep previous EPUB versions and restore one when needed NO ACCOUNT NEEDED Reading, importing and organisation work offline. Your EPUB files and story text stay on your device with no limitations on library size or organization features. TRACE SYNC IS OPTIONAL ADD ON Connect a free Trace account to sync up to 100 stories, restore library details and reading progress on a new device, and access your reading library from any browser. Trace Unlimited adds unlimited Reader sync and private reading Stats. Trace also gives you access to the Trace extension, which lets you track your online reading in the same way you track your EPUB reading, storing it all in the same online library. A subscription is never required to read, import or organise EPUBs on this device. EPUB files are not included in sync right now. Trace Reader is an independent, unofficial app. It is not affiliated with or endorsed by the Organization for Transformative Works or Archive of Our Own.

The call
