### 5/5 — 감사합니다

*2025-10-21*

덕분에 평화롭게 살고있습니다

### 5/5 — RCS 메시지 지원 여부

*2025-09-25*

안녕하세요! 앱 출시 했을 때부터 쭉 사용해오던 유저입니다..!! 너무 훌륭한 어플 만들어주셔서 감사합니다ㅎㅎ

iOS 26 업데이트에서 새롭게 생긴 RCS 메시지에는 키워드 기반 필터링이 작동하지 않는 것 같은데 확인해주실 수 있나요? 감사합니다!!

### 5/5 — 감사합니다

*2025-09-21*

처음에 설정에 대해 안내해주는 안내페이지 너무 따듯했습니다

아직 제대로 써보진 못했지만 잘 될것이라 기대하며 후원도 해봅니닷 1인개발자 화이팅

### 5/5 — 스팸 필터 관련

*2025-08-02*

안녕하세요. 
그동안 필터링이 완벽히 되어서 편리하게 사용중입니다만 최근에 대략 일주일 전부터 필터링이 안되고 스팸 문자 알림이 및 수신이 되고 있습니다. 어떻게 처리하면 되는지 확인 좀 부탁드리겠습니다.

### 5/5 — 너무 좋아서 유료로 쓰고 있어요

*2025-06-23*

그런데 불편한점 두 가지만 말씀드릴게요. 
1. 키워드 같은거 등록하려고 키패드가 올라오면 키패드 때문에 다른 탭화면으로 넘어갈수 있는 방법이 없네요. 

2. 블랙리스트 센텐스가 언제부턴가 등록하면 아래 JSON오류가 뜨면서 등록이 안됩니다.

**Developer response:** 안녕하세요!
1) 부분은 확인했습니다. 다음 업데이트에 UI 변경과 함께 해결될 예정입니다!

2)는 에러 제보 감사합니다. 어디가 문제인지 확인 해 보고, 업데이트 해두겠습니다.(아마 서버쪽에 뭔가 문제가 있나 싶네요..) 감사합니다 :D

### 5/5 — 와 진짜 레전드 차단앱이네요

*2025-06-17*

개발자님 이 앱을 만들어주셔서 감사합니다.
키워드 설정하고 번호 설정하는거 귀찮아서 ai필터링만 딸깍 켜놨는데 사용한지 일주일됐는데 그동안 스팸문자가 하나도 안왔습니다.. 생각나서 메시지 들어가보면 죄다 정크함에 차단되어있구요 ㅠㅠ개발자님 정말 감사합니다. 이 앱을 계속 무료로 쓰고싶어요ㅠㅠ ❤️❤️❤️❤️❤️

### 5/5 — 오류 해결 방법

*2024-11-12*

너무 만족하며 이용하고 있습니다
그러나 앱을 지워도 인스타그램 로그인 코드가 안 옵니다. 이런 문제는 어떻게 해결해야 되는건가요?

**Developer response:** 안녕하세요!

혹시 통신사쪽에서 막힌건 아닌지 한번 확인해보시겠어요..?

앱에서는 정크함으로 보내는 기능은 있지만 오는 문자를 막거나 하는 능력은 없습니다ㅜ ㅜ

### 5/5 — 없어졌을 때, 비로소 소중함을 느낀다

*2024-10-25*

하도 안건들다보니까 그냥 자동으로 앱 보관 처리 되어있었더라구요… 어쩐지 요즘 맨날 라인 19금 문자가 오더라… 
ㅠㅠ 이 어플 강추

### 5/5 — 대박!!

*2024-10-18*

만드신분들께 정말 감사드립니다~ 차단문구 절대 안옵니다 짜증나던일상이 행복해 졌어요 진짜~ㅎㅎ

### 4/5 — 정크 처리된 문자 복구

*2024-10-17*

스팸이 아닌데 정크로 잘못 처리된 문자를 다시 메시지함으로 되돌릴 수 있으면 참 좋겠네요.

**Developer response:** 안녕하세요.
저도 이 기능 꼭!!! 만들고 싶은데 ㅜㅜ 애플이 아직 지원을 안해줍니다.
유일한 방법으로는.. 해당 번호를 연락처에 이름 없이 등록하시면 일단 일반 문자함으로 들어가거나 혹은 최소한 다음 문자부터는 일반 문자함으로 들어갈거에요.!

만약 애플이 이 기능 추가하면 곧바로 추가하겠습니다!!
