## What is LiBook?

LiBook is a personal reading app that brings all your ebooks together in one place.

Import your EPUB, PDF, and TXT files, organize them into your library and collections, and pick up right where you left off. With support for table of contents, search, bookmarks, and highlights, you can easily find what you need—even in long books—and come back to it whenever you want.

With iCloud, your reading experience continues seamlessly across your devices.
Your books, highlights, and reading positions are stored in your own iCloud and stay in sync across devices using the same Apple Account. If a book isn't currently stored on your device, a download indicator appears on its cover, allowing you to download it whenever you need it. You can also download an entire collection in advance for offline reading. When you need to free up storage space, you can remove books from your device while keeping them safely stored in iCloud.

Keep track of characters while reading novels and long-form books.
In EPUB and TXT books, you can select a character's name and save it as a character card with your own notes and descriptions. You can also see where a registered character appears throughout the book, making it easier to keep track of characters in stories with large casts.

Customize your reading experience to suit each book and your preferences.
For EPUB books, you can adjust font size, line spacing, paragraph spacing, margins, themes, and more. For PDFs, you can configure screen fitting, scrolling direction, and page-turning behavior.

When reading isn't convenient, listen to your books with TTS.
LiBook supports play, pause, previous and next navigation, adjustable speech speed, and a sleep timer, so you can listen comfortably whenever you want.

### 5/5 — 너무 좋아요!

*2026-10-07*

리더 중에 가장 좋습니다! 안드로이드용도 만들어주세요

### 5/5 — 건의사항

*2026-10-06*

1. 끝까지 다 읽었는데 진행률이 98%로 떠서 완독탭에 이동이 안 돼요.
파일 점3개 누르면 읽기완료 누를 수 있게 만들어주시면 너무 좋을 것 같아요. 자동으로 완독탭에 안 가는 것들 수동으로 옮길 수 있게! 
2. 파일이 많아서 스크롤바가 있으면 편할 것 같아요. 검색기능이 있지만 뭐가 있는지 볼 때 슥슥 내리는데 다시 올라가기 힘듭니다.. 맨 위로 가기, 맨 밑으로 가기 버튼도 있으면 좋을 것 같아요

**Developer response:** 버그 신고해 주셔서 감사합니다.
말씀해 주신 완독 탭으로 이동되지 않던 문제를 수정했으며, 다음 버전부터 적용될 예정입니다.
또한 책장에서 책을 롱탭(꾹 눌러)하면 원하는 책을 수동으로 완독 탭에 추가하거나 다시 뺄 수 있는 기능도 추가했습니다.
말씀해 주신 스크롤 부분은 사용성을 고려해 개선할 수 있는 방법을 고민해 보겠습니다.
소중한 의견 보내주셔서 감사합니다!

### 5/5 — 찾았던 앱이예요

*2026-10-04*

텍스트뷰어 여러개 깔아봤는데 제일 깔끔하고 마음에 듭니다 정착

**Developer response:** 좋은 평가 남겨주셔서 정말 감사합니다. 여러 텍스트 뷰어를 사용해 보신 후 정착해 주셨다니 더욱 기쁘네요. 
앞으로도 깔끔하고 편하게 사용할 수 있는 앱이 되도록 꾸준히 개선하겠습니다. 감사합니다!

### 5/5 — 건의사항

*2026-10-03*

페이지넘기기 세부설정이 필요해요!
왼쪽버튼을 눌러도 다음페이지로 넘어가게 설정하고싶은데 이 앱은 아직 안되네요ㅠㅠ

그 외에는 너무 편합니다ㅎㅎ

**Developer response:** 의견 주셔서 감사합니다. 말씀해 주신 기능을 추가하여 다음 업데이트에 반영하겠습니다.

### 5/5 — 책을 열 수 없습니다

*2026-10-03*

파일이 삭제되었습니다, 하고 나오네요. 업데이트 후 증상입니다.

**Developer response:** 안녕하세요. 이용에 불편을 드려 죄송합니다.

현재 Libook에서는 말씀하신 ‘파일이 삭제되었습니다’라는 문구가 사용되는 부분이 확인되지 않아, 정확한 증상을 파악하기 어려운 상황입니다.

번거로우시겠지만 해당 문구가 표시된 상황이나 발생 경로 등 조금 더 구체적인 내용을 miriworksdev@gmail.com으로 보내주시면 확인 후 문제를 해결할 수 있도록 최선을 다하겠습니다.

이용에 불편을 드린 점 다시 한번 사과드리며, 제보해 주셔서 감사합니다.

### 4/5 — Better collection organization

*2026-09-28*

I really love this app, it has a lot of things I was looking for in an epub/pdf reader and has done so much well. Thank you to the developers for making this app! However my only critique is how making collection folders to organize your books seems to work. When I add books to a collection, it randomizes all the books even if I have them numbered or put them in a certain order. It doesn’t let you manually move around the files either, like Apple Books does. This is my only issues mostly because I have multiple books that I had to save chapter by chapter to an epub reader, and when I try to organize my books with collections I’m stuck with folders where the chapters are all over the place or chapters that aren’t numbered are mixed up to it’s even harder to tell what’s what. That’s my only suggestion!

**Developer response:** Thank you for the review. We looked into the issue where chapter books in a collection appear out of the numbered or intended order.

A fix is included in the update currently in review. Once it is approved and released, you can long-press a book in a collection, open Details, and edit the title. The updated title is applied to Title sort right away. If the chapter number is in the title, volume 2 comes before volume 10. For chapters without numbers, edit the titles to match your reading order and then choose Title sort. The default sort in a collection is Date Added, so you will need to switch to Title sort to see this order.

We are still considering a way to drag books into a custom order, as in Apple Books.

Thank you for reading with LiBook.

### 5/5 — 아주 잘쓰고 있습니다

*2026-09-28*

작은 건의 사항있습니다. utf-8 등이 아닌 txt 파일을 불러오면 오류 팝업창이 뜨고 이 파일을 지워도 계속 실행할때마다 뜹니다. 이 부분 확인 후 조치 가능할까요! 너무 잘 쓰고 있습니다

**Developer response:** 소중한 의견 감사합니다. 

말씀해주신 것처럼 UTF-8이 아닌 TXT 파일을 불러온 후 파일을 삭제해도 실행할 때마다 오류 팝업이 나타나는 문제를 확인했습니다.

해당 부분 수정해서 다음 버전부터 반영될 예정입니다.
불편을 드려 죄송하며, 앱을 잘 사용해주신다니 정말 감사합니다!

### 5/5 — 작은 건의사항이 있습니당

*2026-09-24*

이 앱을 너무 잘 쓰고 있어요 근데 아예 스크롤 모드를 나눠주실 수 있으신가여 문단 넘어갈 때 
스크롤로 넘어가고싶은데 꼭 스와이프를 해야돼서 몰입이 깨져서요 문단도 스크롤로 내릴 수 있게 해주셨으면 좋겠어요!!

**Developer response:** 말씀해 주신 의견에 저도 공감합니다. 다만 현재 앱 구조상 수정이 쉽지 않아 당분간은 적용하기 어려울 것 같습니다. 그래도 언젠가는 꼭 개선할 수 있도록 고민해 보겠습니다. 좋은 의견 보내주셔서 감사합니다.

### 5/5 — 스크롤 모드 개선 요망

*2026-09-19*

폰에서 사용중인데 가끔씩 실수로 좌우 스와이프를 할 때가 있습니다. 다시 돌아가면 마지막으로 읽은곳이 아니라 그 장의 맨 처음이거나 끝으로 가버리니까 읽던 곳을 찾아야하는 번거로움이 있습니다. 스크롤 모드가 좋은데 이 점 때문에 불편합니다.

**Developer response:** 안녕하세요~ 소중한 의견 주셔서 감사합니다.

말씀해 주신 내용을 반영해 스크롤 보기 모드의 읽기 경험을 대폭 개선했으며, 현재 앱스토어 심사를 요청한 상태입니다.

빠르면 이번 주 중 업데이트된 버전을 이용하실 수 있습니다.
더 편하게 읽으실 수 있도록 계속 개선해 나가겠습니다. 감사합니다!

### 5/5 — 정렬기능이 아쉽습니다

*2026-09-06*

여러모로 편리하고 너무 좋은데 정렬 기능이 아쉽습니다. 전체책 화면에서는 정렬이 잘 적용되는데 개별 컬렉션에서는 정렬이 전혀 적용되지않고 책들의 순서가 뒤죽박죽입니다. 이 점만 고치면 킨들앱 안 부럽습니다,

**Developer response:** 리뷰 남겨주셔서 감사합니다.
말씀해주신 정렬 문제를 확인했고, 컬렉션 안에서 정렬이 제대로 적용되지 않던 부분을 수정했습니다.
수정된 버전은 현재 앱 심사를 요청한 상태이며, 심사가 완료되면 약 2~3일 후부터 업데이트된 버전을 이용하실 수 있을 것으로 예상됩니다.
불편한 점을 직접 알려주셔서 정말 감사합니다.
