### 4/5 — 너무 잘 사용하고 있어요!

*2023-03-16*

깔끔하고 심플하고 몇년동안 여러 어플 사용해봤는데 항상 이걸로 돌아와요 너무 좋은데 딱 하나 아쉬운점은 지나간 날을 수정하거나 추가하지 못한다는거 ㅠㅠ 어제 까먹고 표시 못했거나 아니면 늦게 운동해서 12시를 지나버리면 해당 날 아무 기록도  못하고 그
다음날로 기록 되어 버리는데 참 아쉬워요! 추가나 수정 기능만 있다면 저에게는 정말 완벽 그자체인 어플!!!

### 5/5 — 저도 잘쓰고있어요!

*2021-03-06*

앱 디자인이 깔끔하고 사용하기 정말 편해요!! 그런데 만약 추가된다면 더 좋은 기능은, 사진을 앱에서 찍으면 앱에서만 저장이되고 폰 앨범엔 저장이 안되게끔 되어있어요! (앱 설명읽으니 일부러 그러신 듯) 그런데 앨범에 저장 할 수 있는 옵션도 추가해주시면 좋을 것 같아요! 전 현재 앱으로 식단이나 모습 사진찍고 앨범에 저장이안되니까 일반 카메라로 들어가서 다시찍는데 여간 귀찮은일이아니더라고요ㅠㅠ 그리고 이건 수정안되도 괜찮지만 무언가 입력할 때마다 위에 창이 내려오면서 노티로 떠요 “입력되었습니다” 이런식으로 그건 없어도 될 것 같아요! 내려올 때마다 손가락으로 다시 올리고 다음 내용을 추가해야하니까 하루 몰아서 아침점심저녁 식단이나 그날 내용 추가할 때 살짝 귀찮더라고요! 아무튼 이건 제가 앱을 거의 한달 가까이 쓰며 조금 개선되었음 좋겠다 하는 부분이지 너무 잘쓰고있어요! 강력추천 달력에 표시된 몸무게가 한눈에 정말 잘보여서 뿌듯해요

### 5/5 — 너무 좋아요!

*2020-07-11*
