앱 리뷰 처음 씁니다

몇년동안 쓰고 있었는데 최근 광고가 나오게 업데이트 된 이후, 쓰기가 불편해졌습니다. 단순 광고만 나오는 게 아니라 광고때문에 시간, 기록 정확성이 떨어졌습니다. 하루에 몇초만 투자해도 관리가 되는 목적으로 쓰고있었기 때문에 이런 오류는 치명적입니다. 광고를 없애달라는 게 아닙니다. 작게 만들거나 기록 오류라도 없애주셔야 쓸 수 있습니다. 본인은 애플워치와 위젯으로도 간단을 표시해두는 유저입니다.

잘쓰고있오요

잘쓰고있어요. 다만 개편되기전에 진짜 간단했을때가 그립습이다.. 달력에 간헐적단식 성공하면 o,x로? (아니면 o표시만 있었던가?) 표시가 되서 O 채우는 맛에 열심히 사용하고 살도 많이 뺐었어요. 몇년전에 그 기억으로 다시 사용을 하려고 설치를 했는데 그 맛이 안나네요 ㅠㅍ 그런 기능 하나 넣어주시면 안될까요?

단식 첼린지도 있었으면 좋겠어요!

초보자를 위한 16:8 일주일부터
기습단식으로 몸을 초기화할 수 있는 일주일 첼린지 등등이요!
기록하기 너무 좋고 알아서 계산해주니까 머리 굴려가며 안해도 되서 넘 좋아요ㅋㅋㅋ 잘 사용하고있어요 :) 늘 감사합니다!

이제까지 잘 쓰고 있었습니다.

그런데 어느 순간부터 징그러운 광고가 뜹니다.
손바닥 위에 무슨 카피바라? 지비츠가 엄청 많이 있는 건데 저만 징그럽다고 생각하는 건지 궁금하여 다른 사람들께도 여쭤보니 저만 생각하는 게 아니더군요.
심지어 단식과는 전혀 연관성도 없는 창이라 볼 때마다 들어가기 꺼려집니다.

간단앱 시작! 조금 아쉬운점^^

안녕하세요. 오늘 부터 간헐적 단식을 하려고 하는데요. 앱 관련 추가 하면 좋을 것 같아서 문의 드려봐요. 저는 인바디와 핏빗을 같이 사용하고 있는데요. 애플워치 한가지만 호환이되서 아쉽더라구요. 앱을 이용할때 관련 호환되는 기계들에 종류가 다양하면 앱을 더 완벽하게 사용할 듯 합니다.
