## What is SMSReader?

SMSReader is a reader for digital books and documents, built to be fast and comfortable. Even in a book of thousands of pages, the next page appears the moment you tap the edge, and holding the edge flips through pages at speed.

BUILT FOR THE LATEST DEVICES
• The most comfortable PDF viewer on iPhone Duo
• Extensive accessibility support (VoiceOver and more)

FAST PAGE TURNING
• Tap the left or right edge to turn the page instantly, or choose a slide animation
• Hold an edge to flip continuously (7 speeds, from 6 to 60 pages a second)
• Flick, drag the slider, or type a page number to move
• Pinch in to go straight to an overview of the pages

EASY TO READ
• Home View: remembers, for each book, the area you want to zoom into, and keeps that zoom as you read on one view at a time. Scanned books with wide margins and two-column pages become easy to read
• Right to left (vertical Japanese), left to right, or top to bottom. Two-page spreads and a cover shown alone are set automatically from the PDF
• Tall pages fit the width of the screen, handy for PDF screenshots of websites

EPUB
• Read reflowable and fixed-layout EPUBs, turning pages as fast as with PDFs
• Vertical Japanese, ruby, tate-chu-yoko and emphasis marks, in the book's own fonts if you like
• Choose the text size, font, margins, line spacing and paper for each book
• Press and hold an illustration to see it over the whole screen, and pinch to zoom. Pictures larger than the page are fitted to it

LISTEN AND SPEAK
• Read Aloud: reads the text, leaving out running heads and page numbers, and follows the ruby in Japanese. The word being read is highlighted; start from any word, or move a paragraph back or forward
• Turn Pages by Voice: say "next", "previous" or "page 12". Speech is recognized on the device
• Siri and Shortcuts: "Continue reading in SMSReader", "Read aloud in SMSReader" and more

SEARCH AND ANNOTATE
• Search the text of a book or of your whole library, without missing words split across lines, with your search history at hand
• Select text to copy, look up or share, including vertical text and text with ruby
• Pages without text, such as scanned books, are read on the device and can be searched, selected, translated and read aloud
• Annotate and highlight pages with Apple Pencil or your finger (iPadOS 26 or later). The PDF itself is never changed

TRANSLATION AND SUMMARIES
• Open the translation panel beside the page to see a translation of each paragraph. Tap a paragraph to match the original and the translation
• For translation and summaries, use Apple Translate, Apple Intelligence (on device), or an online translation or AI service with your own API key

BOOKSHELF
• Organize your library in folders, and folders within folders
• Keep the library on this device, in iCloud Drive, or in a folder the Files app can open, such as Dropbox. Books in the cloud are downloaded when you open them
• Drop a whole folder to import its PDFs and EPUBs
• Sync where you are, bookmarks, annotations, shelves and more across your devices with iCloud
• Join several books to read them on as one
• Password-protected PDFs open with their password
• Shelves, one for each shelf tag, work across folders, and a folder can be filtered by shelf tag
• Use any page or image as a cover. Books can also be hidden
• Lock the whole app or single books with a passcode and Face ID

PRIVACY
• No ads, no account, no analytics
• Books, bookmarks, annotations and settings stay on your device; with sync on, they are kept in your own iCloud
• Text is sent to an outside service only when you have set your own API key, confirmed where it goes and agreed, and then run a translation or summary
• Text selection and AI features such as translation and summaries are off for PDFs that forbid copying

For iPad and iPhone (Duo), iPadOS / iOS 18 or later (some features need 26 or later).
The app can be shown in Japanese or English.

• Choose the text size, font, margins, line spacing and paper for each book.
• Contents, links, search, text selection, read aloud and translation work just as they do for PDFs.

AND MORE
• Settings are organized into pages by topic.

### 0.3.0 — 2026-10-24

JOINED BOOKS
• Join books picked in the library and read them on as one book. Pages turn on from one book into the next, and search, read aloud, annotations and translation work across them. The books stay in the library as they are.
• Rename a joined book, put its books in another order, add books or take them out. Joined books go into folders too.

READ ALOUD
• While reading aloud, you can turn pages back and forth; the reading keeps its place, and the reading bar takes you back to the page being read.
• Readings of Japanese text are more accurate (improvements for Japanese).

AND MORE
• Bug fixes and better stability.

### 0.2.0 — 2026-10-23

LIBRARY

• Each window remembers how the library is shown and sorted.

READ ALOUD (Improvements for Japanese)
• Kanji without readings are now read as the sentence means them. A word given a reading (ruby) once in a book is read the same way wherever it appears.
• Turn it on in Settings to ask an online AI service how words are read, for even more accurate reading (needs your own API key).
• Heard a word read wrong? Tap "Correct Reading" on the reading bar to register the right reading on the spot. Works with VoiceOver too.

AND MORE
• Bug fixes and better stability.
