A Cozy Book, PDF & Manga Reader for iPhone

iPhones do not open EPUB files out of the box in every app, so you need a reader that supports the format. Quill opens EPUB books directly — import one from Files, iCloud Drive, AirDrop, or a share sheet and it appears on your shelf, ready to read with your choice of theme and typeface. Your place is saved with character precision, so reopening the book puts you back on the exact line.

CBZ and CBR are archive formats used for comics and manga, and iOS has no built-in viewer for them. Quill reads both natively, with no unzipping or conversion, and shelves them next to your books and PDFs. Page position is remembered per file, so long series are easy to pick back up.

Yes — Quill has a built-in Listen mode that uses on-device text to speech to read any EPUB, PDF, or text file aloud, highlighting each sentence as it goes. It supports background audio, AirPods controls, Now Playing on the lock screen, a sleep timer, and playback speeds from 0.75x to 2x. Because the speech runs on your device, it works offline too.

In Quill you tap the globe icon and the entire page reflows into your chosen language — a full inline translation rather than a word-at-a-time lookup. Ten languages are supported, including Ukrainian, and the translation runs on device through the Apple Translation framework. A chunked translator keeps the rest of the book flowing in while you read the first chapter.

Yes. Quill's inline page translation includes Ukrainian among its ten languages, so you can open an English EPUB or PDF and read it as Ukrainian text. Listen mode follows the translation, speaking the page in a Ukrainian voice automatically. You will need the system language pack downloaded, since all translation happens on your device.

Quill treats PDFs as first-class books rather than documents: they sit on the same shelf as your EPUBs and comics, keep a precise reading position, and work with Listen mode for read-aloud. There is no editing, signing, or form-filling — Quill focuses purely on comfortable reading. That makes it a good home for PDF novels, papers, and scanned books.

Quill accepts books from the Files app, iCloud Drive, AirDrop, any app's share sheet, a direct download link, or even a scanned page. There is no account to create and no upload step — files are added straight to your on-device library. Each import is fingerprinted, so adding the same book twice never creates a duplicate.

Yes. Reading, listening, highlights, and your library all work with no connection, because everything is stored and processed on your device. Translation also runs on device once the system language pack is downloaded. You only need a connection to fetch a book from a link or to use optional iCloud sync.

OpenDyslexic is a typeface designed to reduce letter confusion, and Atkinson Hyperlegible was built for maximum character distinction. Quill ships both among its eight typography presets, alongside sliders for text size, line height, and margins. Combined with six themes — including a pure white Snow mode — you can shape the page to whatever reads most comfortably.

Yes. Quill lets you highlight passages as you read and keeps your exact position in every book automatically, so you rarely need manual bookmarks at all. Highlights stay on your device with the rest of your library, and optional iCloud sync can carry them to your iPad or other iPhone.

EPUB text reflows to fit your screen, type size, and margins, which makes it the most comfortable format on a phone. PDF preserves a fixed page layout, which suits scanned books, papers, and anything where design matters. Quill reads both — EPUBs get full typography control, and PDFs keep their layout — so you do not have to convert one into the other.

Yes. Quill's Listen mode supports background audio, so playback continues when you lock the screen or switch apps. You get AirPods controls and Now Playing on the lock screen, plus a sleep timer for reading in bed. The sentence highlight picks up where the audio is whenever you return to the page.

Some do, but Quill keeps your reading private: there is no account, no analytics tied to you, and your library never leaves your device. iCloud sync is optional, off by default, and uses your private iCloud space when enabled. If you delete the app, the files you imported are still yours.
