결제까지해서 쓰는데 프로필사진이 바뀌질 않네요

**Developer response:** Ahsjjqkab님, 안녕하세요. 먼저 이용에 불편함을 드려 죄송합니다. 해당 문제는 네트워크 이슈로 발생할 수 있습니다. 번거로우시겠지만 앱 업데이트 이후 다시 시도해보시고 여전히 문제가 발생하면 skyu.dev@gmail.com 혹은 Settings > 버그 신고하기를 통해 문의해주시면 더 살펴보겠습니다. 앱 사용해주셔서 감사드리며 건강한 주짓수하세요.

### 3/5 — 다시 고치십쇼잉

*2025-09-14*

아니 다 좋은데 업뎃 되고 나서 프리미엄 아니면 무슨 일주일에 2번 밖에 일기를 못습니까?? 
이건 다시 고쳐줘야 사람들이 계속 이용할듯. 그리고 프리미엄도 너무 비쌈

**Developer response:** 주지때라님, 안녕하세요. 먼저 앱을 사용해주셔서 감사합니다. 프리미엄 요금은 연간 결제 시 할인되어 사용하실 수 있으며, 앱 운용에 필요한 비용이므로 양해 부탁드립니다. 즐겁고 건강한 주짓수하세요!

### 5/5 — 정말 좋은 앱!

*2025-06-06*

어플 개발과 관리에 엄청난 노력을 하셨다는게 보입니다!!
이용권 가격이 저렴하면 좋을 것 같습니다 ㅠㅠ

**Developer response:** Mo_zzang님 안녕하세요. Post Black Belt 앱을 잘 사용해주시고 노고를 알아봐주셔서 감사합니다 😊 이용권은 연간으로 구매할 경우 더 저렴하게 사용할 수 있으며, 가격 정책은 말씀해주신 피드백을 잘 참고하겠습니다! 건강하고 재미있는 주짓수하세요!

### 1/5 — 5번 체크 가능한데

*2025-04-05*

주에 5번 체크인지 뭔지
제대로 안 됩니다

**Developer response:** 옘병2님 안녕하세요. 먼저 사용에 불편을 드려 죄송합니다. 해당 버그는 수정되어 버전 3.1.2로 업데이트 시 정상 사용 가능합니다. 버그 제보는 앱 내 "의견 보내기" 혹은 인스타그램으로 연락주시면 최대한 빠르게 수정해드리고 있습니다. 좋은 한 주 보내세요 😊

### 4/5 — 주짓수인들이 하기 정말 좋은 앱인거 같습니다 다만 단점은 한국어가 없단점…

*2023-12-23*

..

**Developer response:** 알래알래 시티즌님 안녕하세요. 앱을 사용해주셔서 감사합니다. 한국어는 아래와 같이 설정을 변경하면 사용하실 수 있습니다.

### 3/5 — 공유 기능 작동 안해요.

*2023-06-29*

공유 누르면 애어 드랍만 나오고 실패만 뜨네요.

링크 공유 가능 한거 아닌가요?

프로필 수정에도 버그가 있어요.

**Developer response:** 아오뽑기운님, 안녕하세요. 버그 제보 감사드리며 해당 사항 수정되어 앱 업데이트 시 정상 사용 가능합니다. 공유 기능의 경우 링크가 아닌 이미지 저장으로 확인하실 수 있습니다. 사용에 불편함을 드려 사과드리며 주짓수를 좋아하시는 분들을 위해 취미로 개인 개발 중인 앱이니 너그러이 감안해주시면 감사하겠습니다. 또한 버그 제보의 경우 리뷰보다 이메일이나 인스타로 알려주시면 더 빠르게 대응해드리겠습니다.
