### 2/5 — 몇가지만 더 되면 좋을듯

*2026-08-12*

커브기능. 색상별수정(HSL). 썸네일 크기 변경기능(3x3).
사진 편집시 사진이 너무 작아짐.  
이 부분들 업그레이드 됐으면 좋겠네요.

**Developer response:** 안녕하세요😊 커브기능은 빛 항목에서, 색상별수정은 컬러-색상 믹서와 3단 톤 기능으로 이용가능합니다 :)

썸네일 크기 변경기능과 사진이 작아지는 사항은 mutzin@mutzin.com 혹은 인스타그램 @mutzinstudio 로조금더 자세히 설명해주시면 당장 적용해 누구에게나 만족스러운 앱으로 만드는데에 큰 도움이 될 것 같습니다🙇🏻‍♂️

제가 개발하면서 체크하지못한 부분 말씀해주셔서 감사합니다. 꼭 연락주세요..!!!

### 5/5 — 다양한 혁신적 기술들

*2026-07-20*

급하게 증명사진 찍는데 덕분에 편하게 잘 썼습니다. 풍경사진 말고도 다른사진들 보정할때도 굉장히 좋을거 같습니다. 저장 화질 기능이 있어서 이미지 용량 조절도 쉽게 할수있고, 기능들도 너무 신기했습니다. 특히 ai기술 이용해서 다양한 기능들 많던데 정말 유용하게 잘 쓸거 같습니다. 이런 기능을 이정도 가격에서 쓸수있다는게 놀랍네요

**Developer response:** 다양한 부분에서 활용해주셔서 감사합니다.
누구에게나 만족스러운 보정앱을 개발해나겠습니다.
감사합니다📸

### 5/5 — 잘 써볼게요!

*2026-07-18*

오래오래 업뎃해주세요😄

**Developer response:** 이용해주셔서 감사합니다.
꾸준히 업데이트 해나가고있는데, 제가 개발하면서 발견하지 못한 부분이 자주 발생하는것 같아 이용해주시는 분들께 항상 죄송한 마음입니다.

꾸준히 사용해보시고 불편한 사항은 mutzin@mutzin.com 혹은 인스타그램 @mutzinstudio로 연락주시면 빠르게 조치하도록 하겠습니다. 감사합니다📸

### 5/5 — 좋네요

*2026-07-15*

이가격에 구독아니고 마스크되고 지우개되고 좋은데요?

**Developer response:** 좋다고 하주시니 정말 너무너무 감사한 마음입니다..!
누구에게나 부족함 없는 보정앱을 제공할 수 있도록 노력하겠습니다.🙇🏻‍♂️

### 5/5 — 최고의 보정앱

*2026-07-14*

진짜 앱 평가댓글 잘 안다는데 이 앱은 제가 사진보정하는데 너무 도움을 받아 안쓸 수가 없었습니다. 무엇보다 사진에 진심이신 분이 만든것같은 느낌이 들었고요. 제가 원하는 기능이 쏙쏙 있어 정말 유용했습니다. 다들 한번씩 꼭 써봤음 좋겠는 앱입니다.

**Developer response:** 이런 리뷰를 받게되어 영광입니다.
앱은 부족함이 많지만 그 부족함에 보답할 수 있는 앱으로 성장시켜나가는 모습 꾸준히 보여드리겠습니다.
이용해주셔서 감사합니다.📸
