### 5/5 — 몇년째 잘 사용하고 있는데 건의사항

*2026-06-26*

폰트랑 글자크기 배경같은건 설정에 들어가지 않고 화면에서 바로 변경하는 기능은 업데이트 안되나요? 특히 폰트는 책을 읽을때 자주 바꾸는 편인데 실시간으로 바뀐게 확인이 안되서 화면을 왔다갔다 하는게 불편해요ㅜ 아니면 설정에서 미리보기 같은걸로 적용된 부분을 볼 수 있게 되면 좋겠습니다 또 상단 아이콘중에 안쓰는 기능이 많은데 헷갈리고 거슬려서 숨김처리 할수있게 해주세요 더 욕심내면 상단에 추가 할 수 있는 기능들이 더 늘어나서 각자 원하는 기능만 즐겨찾기처럼 선택할수 있으면 깔끔하고 정말 편할거 같습니다 설정 화면은 아직도 좀 복잡하고 길어서 간단한거 자주 바꿀때는 좀 번거로워요ㅜ

### 4/5 — とても便利

*2025-11-09*

PDFを高速で表示してくれるので、クラウドに保存した資料の閲覧に重宝します。
ただ検索機能が欲しいですね。

### 5/5 — 최고의 앱

*2025-10-19*

호환성 좋고 쓸데없는 디자인없이 깔끔한 ui  다양한 기능 완벽합니다

### 5/5 — 최고의 리더앱

*2025-09-25*

성능도 좋고 지속적인 업데이트로 아주아주 좋음

### 4/5 — 良い

*2025-09-19*

読むこと、読みやすさに特化していて、とても良いです。細かくカスタマイズできます。もしかするとepubでの目次機能と拡大機能が無いのかな？

### 5/5 — Worth it

*2025-07-28*

Turns books of most file formats into a customizable infinite-scroll experience. Far and away the most modular and powerful phone reader I have ever used! Worth every penny.

### 4/5 — 투박하지만 만족스러운 성능

*2025-04-09, version 1.372*

ux가 전체적으로 투박합니다 디자이너 없이 프로그래머 1인이 만든것같은 투박함입니다
여태 써오던 다른 앱들보다 기능은 많고 하나의 앱이 다른 앱에서 할 수 있는 모든것들을 대체하여 좋습니다만 스트리밍 기능이 없고 무조건 파일을 다운받아야하며, zip파일의 경우 압축을 해제하여야한다는 불편감이 있어 별 하나 뺐습니다
다른 앱처럼 다운 받을 필요없고 zip도 곧바로 열리는 기능이 있다면 좋겠네요

### 5/5 — 책읽기에는 최고

*2025-03-21*

세세한 설정도 좋고 책이나 이미지 다 잘불러옵니다^^
아주 잘 사용하고 있어요
기능하나 추가가 가능하실지 문의드려요
SMB, FTP도 정말 편한데
OPDS도 연결이 가능했으면 더할나위가 없을것 같습니다
좋은앱 만들어주셔서 감사합니다

### 5/5 — 문의사항이 있어서 남겨요

*2025-03-17, version 1.371*

혹시 표지가 처음부터 보이게 햐주시면 안되나요? 넣어둔 작품이 한국어가 아닐경우 이게 뭐였지 하면서 무조건 눌러봐야하는데 그러기엔 너무 많은 작품을 넣어둬서요 그리고 아이패드에서 계속 로딩하다가 그냥 써지는 현상이 있네요 그런것들빼면 진짜 잘 이용하고 있습니다!

### 5/5 — TTS(읽어주기) 멈춤현상 해결 부탁드립니다

*2025-02-16, version 1.370*

정말 잘 사용하고 있는 어플입니다.
한가지 아쉬운 점은 운전할때 무선 충전을 하면서 네이버 지도로 네비게이션을 작동하고, 만화와 텍스트 어플로 TTS(읽어주기) 실행시 멈춤 현상이 너무 자주 일어납니다. 아이폰 15 프로 사용중이고 최신 소프트웨어이며 어플도 최신 업그레이드 항상 하는데 이 문제는 해결이 안되네요. 정말 잘쓰고 있는 어플인데 저 문제좀 해결 부탁드립니다.
