### 5/5 — 업데이트 해주세요!!

*2025-10-23*

앱이 엄청 깔끔하고 좋은데 과거 알림도 볼 수 있게 해주셨으면 좋겠습니다! 한 번 알림 뜨면 다시 볼 수 없어서 조금 불편해요.. 잘 쓰고 있습니다, 감사합니다!

### 4/5 — 너무 좋은데 추가 업데이트 부탁드립니다

*2025-10-23*

1. 저장 되어있는 이벤트를 볼 수 있는 목록이 있으면 좋겠습니다.(최신순으로라도 볼 수 있는)
2. 상대가 이벤트를 수정하면 기존에 있던 사진이 사라지지 않아야 할 것 같습니다.
이렇게만 수정되면 정말 오래오래 잘이용할 것 같습니다 !!

### 5/5 — 남친이랑 진짜 잘 쓰고 있어요!

*2025-09-21*

추억을 남기기도 너무 좋고 최고에요!
다만 사진을 올리면 순서대로 안올려지고 추가하려니까 기존에 있는 사진이 사라지고 새로운 것만 올라가요ㅠㅠ

버그인지 아닌지 모르겟는데 이것좀 부틱드려요

### 5/5 — 너무 좋은데 백업기능 추가해주세요

*2025-07-16*

레토 진짜 너무 좋아서 처음으로 어플 리뷰도 남겨봅니다. 다만 공들여 쓴 내용이 날아가거나, 어플 서비스기간이 종료될까봐 걱정되요 ㅠㅠ 평생 쓰고싶은데 백업해서 메일로 보내는 기능 추가 안될까요? 개발자님 부탁드립니다!

### 3/5 — Nice calendar app

### 5/5 — 키보드가 안사라져요

*2025-02-23*

아이폰15프로 사용중인데 일정 추가하고 달력 화면으로 나오면 키보드가 사라지지 않아서 네번째 주 일정 추가하려면 나갔다 와야하고.. 일정을 카피하거나 이동하려고 하면 지정한 날짜의 하루 앞으로 생성되고 자잘하지만 많이 불편한 오류들이 많네요 개선되기를 바래봅니다..

### 5/5 — 다 좋은데 조금 아쉬워요 ㅠㅠ

*2024-12-23*

안녕하세요! 해외 사는 남자친구랑 일정 공유용으로 사용 중인데 기념일을 설정해 놓으면 시차 때문에 서로 다른 날짜로 지정이 되어서 아쉽더라구요 ㅠㅠ
그리고 캘린더 어플 들어가면 10일로 뜨는 일정이 위젯에는 11일로 다르게 표시되더라구요..! 위젯으로 주로 확인하는데 이 부분이 너무 불편해요 ㅠㅠ

### 4/5 — 사진을 업로드 오류

*2024-11-13*

정말 잘 쓰고 있는 어플인데 사진을 다량 업로드시 어플이 계속 튕겨요. 진짜 몇번째인지 모르겠습니다. 수정 부탁드려요. 그래서 조금씩 올리고 저장하려는데 앞에 저장했던게 날아갑니다
