### 1/5 — 没有中文字库

*2026-09-01*

没有中文字库 没有办法看中文书籍 就算转换中文选项还是会丢失很多文字完全没办法阅读 只能看图片类格式而不是文字类的文件 作为这样的软件不值这个价格

### 5/5 — 백업 이 안되고 프로그램이 꺼집니다

*2026-08-02*

이거 안드로이드 앱과. 진행량 연동되나요?

### 2/5 — SMBが使えない

*2026-07-26*

NASに保管しているデータを呼び出そうとしましたが、つながりません。Android版は問題なかったのでiOS版の問題と思います。
なお、閲覧性など基本機能はAndroid版とほぼ同じかと思います。
