### 5/5 — 너무 좋음

*2025-11-11*

너무 잘 쓰고 있어요 광고? 이런 거는 그냥 들어가서 텍스트 입력하고 검사하기 누를 때 결과가 바로 나오는게 아니라 로딩 중일 때가 있거든요 그러면 그냥 나가서 앱 창 지웠다가 다시 들어가면 광고 없이 봐로 쓸 수 있어요

### 2/5 — 광고

*2025-05-30, version 3.1*

좋은데 광고 나오는 것도 괜찮은데 광고가 안 닫혀요ㅠㅠㅠ

### 3/5 — 광고

*2025-05-14*

아니 연간 결재 했는데 앱에는 안 나오지만 상시 하단에 광고 패널 너무 거슬리는데요. ㅠㅠ

### 3/5 — 과한 광고

*2025-03-13, version 3.0*

광고가 너무 많습니다. 2회당 한번 광고는 심합니다. 50%가 광고니까요. 
개선 요망합니다.

### 3/5 — 검사는 좋아요

*2024-07-30*

말그대로 검사는 좋아요 근데 광고 시간이 너무 길어요 
무료 어플이니 감안해야한다고 생각하지만 조금만 더 짧아지면 좋을 것 같습니다

### 1/5 — 다른어플로 갈아탐

*2024-03-23, version 2.4*

가독성 개 헬이고 광고 진짜 지옥이라 
버리고 딴데갑니다

### 2/5 — 엉터리도 이런 엉터리가 없어요

*2024-02-07, version 2.4*

편의성은 뛰어난데 문서에 있는 글귀를 복사해서 붙혔더니 인식이 많이 이상합니다
