## What is Bookbreath?

Bookbreath is a reading app with no ads. The name is Korean for "the breath of a book".
No banners, no pop-ups, no video ads. When you read, there is only text.
Made for people who loved e-ink readers and now read on their phone.
On iPhone Duo, unfold it and read two pages side by side, like a paper book. Fold it and keep reading one page at a time on the outer screen.

Easy on the eyes
• The page is never brighter than the room around you, with less flicker in the dark
• Warm grey paper without blue glare, warmer after sunset
• Black & white mode for this app only
• Turn page by page with your choice of effect, or scroll straight down (trial)
• The screen stays on while you read, and brightness is right there in the reader

Any file, fast
• TXT, EPUB and PDF — password-protected PDFs too
• Read any PDF like a book with “Text Only”: bigger text, your font, highlights. Scanned PDFs are read on your device
• Old TXT files in GBK, Big5, Windows-1251, KOI8-R, Shift-JIS, EUC-KR and other legacy encodings open without garbled text
• Import a ZIP of books in one go
• EPUBs keep their own table of contents and footnotes
• Even books thousands of pages long open in about a second
• Link your Downloads folder once and new books appear right away
• Find, sort and rename books in your library
• On iPad in landscape, two pages side by side like a book — PDFs too, with contents and search

While you read
• Highlights, notes, bookmarks and full-text search; step through matches with ‹ ›
• Long-press to select, drag the handles, and carry on onto the next page
• Share a passage as a paper card image
• Dictionary and translation
• Read aloud in the book's own language with natural voices and a sleep timer (10 free minutes a day)
• Turn pages with a keyboard or a Bluetooth page turner
• Choose what the page header and footer show: title, chapter, pages left, time left, percent, progress bar
• Home Screen and Lock Screen widgets, plus today's reading time and your streak
• Lock the app with Face ID
• Export highlights and notes as text
• Literata, Charter and Korean book fonts, remembered separately for Chinese/Japanese/Korean books and all others; Chinese, Vietnamese and Cyrillic books get a typeface with every letter
• In 16 languages: English, 한국어, 日本語, 简体中文, 繁體中文, Español, Français, Deutsch, Italiano, Português, Русский, Nederlands, Türkçe, ไทย, Tiếng Việt, Bahasa Indonesia

Bookbreath Pro — buy once, keep forever (not a subscription)
• Fine typesetting: line and paragraph spacing, letter spacing, margins, weight, alignment
• Different fonts, spacing and margins per book; save your own presets
• Unlimited read-aloud
• Unlimited highlights and notes (free: unlimited in your first book, then 3 per book)
• Add your own fonts (.ttf, .otf)
• Every paper tone
• Sync between iPhone, iPad and iPhone Duo through your own iCloud: position, highlights, notes, bookmarks, book files and your text settings (no sign-up)

Books bought from stores with DRM protection can't be opened. Bookbreath reads the TXT, EPUB and PDF files you own.

### 5/5 — 재차 볼륨키 페이지 이동 지원요청

*2026-10-23*

다른 독서 앱에선 지원이 되는데...어렵다면 어쩔 수 없죠. 앱 내 메뉴에 문의하기란이 있으면 좋겠습니다.

**Developer response:** 파악사님 이렇게 리뷰 남겨주시고 필요한 기능도 알려주셔서 너무 감사합니다!! 

정말 아쉽게도 애플 정책상 앱이 볼륨 키를 마음대로 못 쓰게 하더군요… 아쉬운 대로 ‘어디를 눌러도 다음 쪽’ 기능을 넣어봤어요!! 

한 손으로 들고 엄지로 화면 아무 데나 톡 누르면 다음 쪽으로 넘어가요. 켜는 곳은 ’눈 편한 화면 - 쪽 넘기기’!! 그래도 볼륨 키 기능은 실험 기능으로 도전은 해보려고 합니다! 될지 안될지는 모르겠습니다만…!!
