Every library.
Every format.
Read your way.

A native reader for your calibre libraries, wherever they are: calibre-web, calibre's own server, Kavita, Komga, your cloud, your NAS, or the device itself. EPUB to DjVu, comics to films. Read it on a page you shape to the last pixel of margin, hear it read aloud, mark it up, or write a book of your own.

One reader. Every place
your books live.

Connect as many libraries as you like and read them as one: All Books shows them together, and each book says where it is from. Libraries on your storage are written to the way calibre writes them, and a calibre library, a folder or a ZIP of books comes onto the device in a tap.

Servers

calibre-web and calibre's own content server: browse, search, shelves, edit metadata and covers, upload, and read with progress kept in step. Kavita, Komga and any OPDS catalog too.

Clouds & shares

Dropbox, Google Drive, OneDrive, Box, iCloud Drive and Files, SMB shares, WebDAV (Nextcloud, ownCloud, Synology, QNAP, pCloud) and FTP.

On the device

Libraries of your own, with no server at all, in calibre's own format. Import a calibre library, a folder or a ZIP, or share a file from any app: each file goes where it belongs.

All formats

If calibre keeps it,
it opens here.

Native engines on the device, no conversion server: reflowed text, fixed pages, scans, comics, office files, sound and film. Even WMA and MKV, decoded on board.

Chapter 1

It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.

However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered the rightful property of some one or other of their daughters.

“My dear Mr. Bennet,” said his lady to him one day, “have you heard that Netherfield Park is let at last?”

Mr. Bennet replied that he had not.

“But it is,” returned she; “for Mrs. Long has just been here, and she told me all about it.”

Mr. Bennet made no answer.

“Do you not want to know who has taken it?” cried his wife impatiently.

“You want to tell me, and I have no objection to hearing it.” This was invitation enough.

Chapter 2

Mr. Bennet was among the earliest of those who waited on Mr. Bingley. He had always intended to visit him, though to the last always assuring his wife that he should not go.

And till the evening after the visit was paid she had no knowledge of it.

Chapter 1

“Is that his design in settling here?”

“Design! Nonsense, how can you talk so! But it is very likely that he may fall in love with one of them, and therefore you must visit him as soon as he comes.”

“I see no occasion for that.”

iPhone Duo

Open, a book.
Folded, still yours.

Made for the iPhone Duo: the inner screen keeps your place as you fold and open it, the tabs move where your thumb is, and the Fold turn echoes the hinge. Fold it shut mid-chapter and choose what the outer screen shows.

Read Aloud & audiobooks

Hear every book.
Or read along.

Any book with words reads itself to you in natural voices made on your iPhone or iPad, in 32 languages. Each sentence is marked as it is said, and the pages turn with the voice. Have its audiobook too? Calibre Reader listens to the recording and finds each page in it: play from any page or sentence, and the book keeps up.

Natural voices

Named voices, women's and men's, fetched once in the app, with nothing to set up in iOS Settings. Other languages are read by the system's own voices.

Read along with the audiobook

Play from Here on any page or chosen words. A recording in parts, a boxed set of several books, or a book that is one volume of a longer recording each find their place.

Hands free

A sleep timer, the Lock Screen and headphones, and Siri: “Continue reading aloud in Calibre Reader.” Scanned pages are read too, even in vertical columns.

Mark up & write

Write on any page.
Or start your own.

Highlight and note any book. On PDFs, scans and pictures, write and draw with Apple Pencil or a finger, and lay text boxes and sticky notes on the page, their words styled one by one as in a word processor. Then begin a book of your own.

Notebooks

A blank book of plain, lined or squared paper in your screen's shape. Write in it, type on a page, add pages as you go.

Manuscripts

Write chapter by chapter, with headings, lists and pictures, kept as a real EPUB that calibre and Apple Books open.

Your notes go where you go

Handwriting, boxes and notes travel in the book's notes file, in an open format. Highlights come in from calibre, a Kindle, Readwise and Notion, and go out to Obsidian, Readwise and Notion. Every mark says who made it, and links lead to another page or the web.

And everything around the page

A library app,
not just a reader.

Notes in your own hand

Highlights, underlines, boxes and margin notes as bubbles, tips, sticky notes or callouts, in any colour and paper. Exchanged with calibre's own highlights.

“…she told me all about it.”Mrs. Long, again. The village news service.

Search inside every book

Full-text search across your libraries, indexed on the device, or through recoll on your own computer. Search the results, or one book.

Pride and Prejudice — ch. 1 · “Netherfield Park is let at last…”

Two books, side by side

Read a book beside its translation, or any two books together, each with its own theme. They move as one, lined up by their words.

Ask the book

Recap what you have read, see who's who, ask a question or have a passage explained. On devices with Apple Intelligence it all happens on the device, from the pages you have reached, so nothing is spoiled.

Read together

Read a book with your club: see where the others are, share notes in the margin, and talk it over chapter by chapter.

Edit together

Share a PDF or a notebook and mark it up at the same time. Strokes appear as they are drawn, and each mark has its own undo.

Vertical text

Japanese and Chinese in vertical columns, paged or scrolled sideways, with pictures fitted and your place kept.

Back in a tap

Put a book down to a small bar and it reopens at the exact place, even after a restart. The player and the reader float out of your way.

Home your way

Every part of Home on or off, in any order, with your own shelves on it.

Albums, series & films

Music and video kept as albums, series and movies, their details from their tags and from catalogues of their own kind. Playlists, subtitles in any font, and MKV or WMA played on board.

Translate & learn

Select words and translate them on the device. Keep them in Vocabulary with the sentence they came from, review them as cards, or send them to Anki.

Reading statistics

Time per book, a heatmap of the year, your reading hours and a Year in Review to share. The page says how long the chapter has left.

Friends, clubs & lending

See what friends read, talk in book clubs with polls and a history you can search, and lend a book from your phone straight to theirs. Optional, and yours to leave.

Share a book whole

Its formats, cover and details, your notes and markup, its theme and fonts, in one file. Another Calibre Reader takes it in just as it was.

In step on every device

With the app unlocked, your place in each book and your notes follow you to your other devices. The books themselves stay where they are.

What the world reads

Home brings the lists of your country: The New York Times, The Guardian, LRB, Perlentaucher, Hebban, YES24 and more, marked when you own the book.

Siri, Handoff, widgets

“Continue reading in Calibre Reader.” Handoff takes the book to your iPad at your page, Spotlight finds it, and widgets and reading goals keep it in sight.

The Daily Quiz

20, 50 or 100 questions on books and writers, on Home. World, or Close to Home on what readers of your language know best, in 40 languages, online or off. Enough right answers earn active days.

Easier to read, for everyone

Easier to Read spaces letters, words and lines, with OpenDyslexic, Atkinson Hyperlegible, Lexend or Andika if you like. Every control speaks to VoiceOver.

Comics, panel by panel

One panel at a time, each zoomed to fill the screen, right to left for manga. Photos of a book laid open turn at their spine.

Covers from a photo

Photograph a book: its cover is cut out, squared up and read, then given to the book it names. Any picture can be a cover, or the page's background.

Private by design

Your libraries, books and notes stay with you. Voices and translations are made on the device, secrets live in the Keychain, and lists are fetched straight from their sites.

PDFs that work

Forms filled in, Acrobat's XFA ones too, watermarks hidden (even those scanned into the pages), and a copy saved without them.

Mobile data, your call

A reminder before large downloads over mobile data, a size limit, or none at all.
