### 3/5 — 콘텐츠 제한

*2026-03-17*

혹시 무료버전에서는 하루에 등록가능한 콘텐츠만 제한되는 게 아니라 문장도 4개로 제한되나요?

**Developer response:** 교교교교교교곡님, 안녕하세요. 

무료 버전에서 문장 개수가 제한되는 현상을 확인했어요.

바로 고쳐서 올리겠습니다. 

소중한 의견 감사드리고, 편안한 하루 보내세요!

### 4/5 — 중국어

*2026-03-08*

안녕하세요 간체자 중국어 가사가 그냥 한자, 번체자로 뜨더라고요… 이것 말고는 너무 좋은 앱인 것 같습니다

### 2/5 — 중국어 인식 안 됨

*2026-02-18*

중국어 인식 가능하게 업데이트하셨대서 깔아봤는데 여전히 중국어를 일본어로 인식하네요... 그렇다고 언어선택을 중국어로 할 수 있는 것도 아님

**Developer response:** 안녕하세요. 
앱 스토어에 새 버전이 올라가면 사용자의 핸드폰에 자동으로 설치되기까지는 며칠이 더 걸릴 수 있어요. 
앱 스토어에서 앱을 최신 버전으로 업데이트 해주세요!
(텍스트를 입력하면 언어 선택 메뉴가 뜰 거에요!)

### 2/5 — 국가설정

*2026-02-16*

중국노래 가사를 넣는데 자꾸 일본어로 설정되어서 사용이 불가능함
노래 추가시에 국가를 선택하게해주시거나 정확도를 높여주세요

**Developer response:** 안녕하세요. 
학습 자료의 언어를 직접 설정할 수 있게 고쳤어요. 
앱 스토어에서 최신 버전으로 업데이트하시면 해결됩니다!

### 3/5 — 언어인식과 선택

*2026-02-15*

안녕하세요 중국어를 일본어로 인식합니다! 설정을 하거나 바꿀 수 있는 방법이 있을까요?

**Developer response:** 안녕하세요. 학습 자료의 언어를 직접 설정할 수 있게 고쳤어요. 
앱 스토어에서 최신 버전으로 업데이트하시면 해결됩니다!
