### 5/5 — 진자 좋음

*2026-06-15*

다이어트 기록 어플 중에 최고임
제일 심플하고 직관적이고 아주 귀여움 ㅠㅠ 찾던 거예요
식단에 인스턴트나 가공육 등등이 추가 되면 좋겠습미다 종류가 많이 없어요 ㅎㅎㅎ 하지만 최고

### 5/5 — (요청) 메모 작성, 캘린더에서 클릭하면 몸무게 편집 가능하게

*2026-05-15*

잘 쓰고 있습니다. 하지만 두가지만 추가하면 훨씬 좋을거같습니다.
1. 활동 말고 간단한 메모를 기입할 수 있는 기능
2. 하단 좌 두번째 “캘린더” 눌러서 나오는 화면에서 원하는 날짜를 한번 누르면 몸무게 작성or수정 가능토록 (현재는 기록 들어가서 상단 < 화살표 눌러서 그 날짜까지 가서 편집 가능)

### 4/5 — 좋아여!!

*2026-02-04*

다이어트 앱 알아보다가 커뮤니티 있는 게 별로라 이외의 것들로 찾아봤는데 이게 딱 뜨더라구요✨ 남한테 평가 받지 않고 혼자 기록하면서 다이어트 하기 좋을 거 같아요! 그래프로도 변화를 볼 수 있답니다ㅏ (그치만 자극이 필요하신 분들한테는 비추..)

### 5/5 — 사용성이 좋은 몸무게기록어플

*2026-01-14*

디자인이 깔끔하고 한눈에 보기쉽고 귀여워서 좋네요
무엇보다 몸무게입력 후 빠지고있는걸 그래프로 확인할수있어 기록&루틴으로 만들기용으로 도움이됩니다

### 4/5 — 체지방률 강제로 적혀지는 거 좀 없애주세요.

*2025-08-30*

체지방률 입력 활성화하면 체지방률을 입력 안해도 기본으로 설정된 숫자로 자동으로 입력되던데 이것 좀 안되게 해주세요.
인바디를 매일 재진 않잖아요? 근데 강제로 입력돼서 되게 거슬리네요.. 가끔만 입력하고 싶은데..
오늘의 기분도 무조건 입력되게하지 않았으면 좋겠습니다.

### 5/5 — 너무 잘썼는데 데이터 저장..?

*2025-03-29*

넘 좋았는데 앱 지웠다 다시 까니까 데이터가 하나도 없네요 ㅠㅠ 폰 바꾸거나 하면 그냥 날아가는 건가요..?ㅜㅜ

### 2/5 — 그래프의 변동이 눈에 보이지 않아요.

*2025-03-25*

추세 그래프에서 목표 몸무게가 -20이면 현재 몸무게에서 -20까지만 보여도 상관 없는데 쓸데없는 범위인 현재 무게 -40까지 자동 설정이 되어서 체중의 변화가 그래프로 보이지가 않아요. 그래프의 범위 설정을 자유롭게 할 수 있도록 부탁드립니다.
또한, 전날 대비 증감무게 표시도 캘린더에 같이 있음 좋을 것 같습니다.
그리고 현재 체중도 아니고 체중 평균은 왜 있는지 모르겠습니다..

### 4/5 — 좋아요

*2025-02-11*

다 좋은데 이게 로그인이나 회원가입 가입 같은데 안되서 폰 바꾸거나 앱을 지웠다가 다시 깔면 그 전 데이터를 불러올수가 없어서 좀 아쉬워요. 그리고 식단 관리에서 음식 종류가 많이 없어서 조금 아쉬워요 그 점만 빼면 다 괜찮아요 친구한테도 추천 해줬는데 잘 쓰더라고요 암튼 그 로그인 빼고는 다 좋은것 같아요

### 5/5 — !!!!하나만 기능추가해주세유 ㅠㅠ!!!

*2025-01-22*

매일 몸무게 기록하기 좋은데요. 추세 기능의 범위가 너무 넓어서 변동폭의 크기가 작아요. 예를들면 현재 55인데 목표는 50 이면, 45까지 최저범위가 설정됩니다. 그래프 최저최고 몸무게를 설정할 수 있는 기능이있음 좋겠어요
