## 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.

### 5/5 — シンプルで速いに限る

*2026-10-29*

シンプルで速い、電子書籍や資料を読むのに必要な機能は網羅されている、これ以上に求めるものはありません。当然電子書籍はDRMフリーでなければなりませんが、オライリーやCQ出版を愛用している私にはぴったりでした。これまではApple標準のBooksアプリを使っていましたが、こちらに移しました。

### 4/5 — すばらしい

*2026-10-25*

これまで、様々なPDFリーダ-を試してきたら、とても使いやすい.
VoiceOverユーザにも使いやすく、声でページの移動ができるのも読書バリアフリーアプリとしておすすめです。Voiceoverユーザーとしては目次のないPDFに自動目次作成ができるとあありがたいです。
