## What is Ru?

Ru turns books into audiobooks, entirely on your iPhone, with no network. Listen to your own books, or pick one of 160 free classics in Ru's Library.

RU'S LIBRARY
• 160 public-domain books, free to download: 54 in Vietnamese and 106 in English
• English: Pride and Prejudice, Sherlock Holmes, Alice's Adventures in Wonderland, Jane Eyre, Little Women, Anna Karenina, Treasure Island and more, from Standard Ebooks' carefully proofread editions
• Vietnamese: Truyện Kiều, Lục Vân Tiên, Tắt đèn, Số đỏ, Giông tố, the stories of Nam Cao and Thạch Lam, Thơ mới poetry and more
• Arranged by kind, with original covers from old printings and classic paintings
• Every author and translator died before 1956, so the books are in the public domain everywhere

VIETNAMESE AND ENGLISH BOOKS
Ru recognises a book's language when you add it. Vietnamese books are read by Vietnamese voices, including the English words and sentences mixed into them. English books are read by English voices, with dates, years, money and Roman numerals spoken the English way. A document in another language is turned away with a short message. The interface is in Vietnamese or English.

Import an EPUB, PDF, Word, TXT or Kindle (PRC, MOBI, AZW, AZW3) file from Files or iCloud, or paste a link to an article, and listen. Text extraction and speech synthesis both run on the device: your books never leave your phone, and the app works the same in airplane mode.

EIGHT VOICES
• Four Vietnamese voices: a woman and a man from the North, the same from the South
• Four English narrators: American and British, a woman and a man, warm and calm for night-time listening
• Three come built in; the others download once (about 61 MB each) and then work offline
• Switch voices while listening; tap a voice you don't have yet to download it
• Designed with AI from written descriptions; no real person's voice is copied

LISTEN ANYWHERE
• Five speeds, adjustable while playing
• Background playback with lock screen controls
• Keeps playing when you leave the reader, with a mini player in the library
• Remembers your place in every book and, if you turn it on, syncs it (and the books too, if you like) to your other iPhone and iPad through iCloud

SLEEP TIMER
Choose a number of minutes, or "end of this chapter". The volume fades over a few seconds and then stops, instead of cutting off abruptly and waking you.

A TIDY LIBRARY
• Covers taken from the books themselves
• Folders, drag and drop to arrange, rename books
• Search by title, or for any sentence in your books, even typed without diacritics
• Search inside the book you're reading, then tap a result to listen from there

READ YOUR WAY
• The page looks like the book: paragraphs flow and poems keep their lines
• The sentence being read is highlighted; tap any sentence to listen from there
• Table of contents taken from the book itself
• Adjustable text size and reading background, including a dark page for night

BUILT FOR VIETNAMESE
Numbers, dates, times, percentages and units become natural spoken Vietnamese. Poems are recognised by their form (lục bát, song thất lục bát, seven- and five-syllable verse, eight-word verse, free verse) and read to its rhythm. Pauses follow punctuation, brackets and line breaks, so the narration sounds relaxed rather than mechanical.

PRIVATE BY DESIGN
No account. Your books are never uploaded to any server of ours; sync, if you turn it on, goes through your own iCloud.

FREE, WITH ADS
Ru is free and shows ads when your phone is online: a banner on the library screen, and now and then an ad when you open a book (never the bundled books). Never while you are listening, and never inside the reader.

## Version history (last 4 releases)

### 2.0 — 2026-10-30

• Ru's Library: Hundreds of classic books, in Vietnamese and English, arranged by kind with their original covers. Open it with the books icon at the top, or the "Thư viện của Ru" shelf at the top of your library.
• English books: Ru recognises English books and reads them with one of four new English narrators, American and British, a woman and a man.
• About 120 MB smaller: the Northern and Southern men's voices and three English voices download when you need them, right from the voice menu.
• The voice menu lists every voice: the book's own language closest to the button, and voices you don't have yet download with a tap.
• iCloud sync (optional): your place in each book follows you to your other iPhone and iPad; turn on the second switch to sync the books too.
• Better pauses at brackets and in poems without punctuation, and fuller tables of contents for Kindle books.

### 1.3 — 2026-10-26

• Đọc sách Kindle: Ru giờ mở được tệp PRC, MOBI, AZW và AZW3, những định dạng các trang sách điện tử tiếng Việt hay chia sẻ bên cạnh EPUB. Ru giữ nguyên mục lục và ảnh bìa của sách. Sách Kindle mua có khóa bản quyền (DRM) thì không mở được.
• Trang sách giờ trình bày đúng như cuốn sách: các đoạn văn liền mạch, thơ giữ nguyên từng dòng. Chỉ câu đang được đọc mới sáng lên, trang tự cuộn theo câu đó, và bạn chạm vào câu nào thì Ru đọc tiếp từ câu đó.
• Thêm sách nhanh hơn nhiều. Không cần chờ cả cuốn được chuẩn bị xong: phần đầu sẵn sàng là bạn mở sách nghe được ngay.
• Chữ Hán, chữ Nga và các chữ không phải tiếng Việt hay tiếng Anh được bỏ qua, thay vì bị đọc vội từng ký tự.
• Đọc tiếng Anh và câu ngắn tốt hơn.

### 1.2 — 2026-10-19

- Bốn giọng đọc mới: Nam/Nữ miền Bắc/Nam
- Đọc được tiếng Anh
- Mini-player ở màn hình thư viện cho phép nghe và điều khiển sách ngay từ màn hình chính
- Quản lý file theo thư mục
- Tìm kiếm từ thư viện và tìm kiếm trong sách 
- Nghe báo từ đường link
