(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? ### 5/5 — 단식 첼린지도 있었으면 좋겠어요! *2025-07-06, version 3.250* 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! ### 5/5 — 이제까지 잘 쓰고 있었습니다. *2025-06-21* 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. **Developer response:** 안녕하세요 5다인님. 우선 불편드려서 정말 죄송합니다.. 해당 부분 광고 확인해서 바로 안뜰 수 있도록 조치하겠습니다! 알려주셔서 감사합니다!!ㅠㅠ —추가 답변—- 간단은 앱 광고 자동 시스템을 사용하고 있습니다 최근 테무에서 광고 클릭 유도하도록 그런 광고를 노출하는걸 알게됐어요ㅠㅠ 그래서 앱에서 전부 차단 완료했습니다!!! ### 5/5 — 간단앱 시작! 조금 아쉬운점^^ *2025-06-14* 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. ### 5/5 — お願いします *2025-06-11* 断食の時間設定を1分単位で決められるようにして欲しいです。 **Developer response:** こんにちは。まずはレビューを残していただき、ありがとうございます。 「体重」タブ → 設定アイコンを選択すると、体脂肪率（％）に切り替えることができます！ ### 3/5 — 깔끔하고 원라는 기능이 있어서 좋아요 *2025-02-23, version 3.227* 스위치온 다이어트 하는데 안성맞춤이에요 근데 식단에 집에서 만든 음식도 추가할수 있도록 했으면 좋겠어요 ++아뇨 다른 어플 같은경우 예를 들어 양배추 볶음밥 하면 재료들과 소스 까지 g단위로 추가해서 레시피로 만들어 하나의 음식을 올릴수 있도록 만들어두는 경우가 많은데 그렇지 못한것에 대하여 말씀드리는거에요 다른 어플들좀 보고 아이디어를 좀 얻으세요 Ai 한줄 입력도 솔직히 불편해요 저는 정확한 값을 넣고싶은데 그게 안되는거니깐 그리고 제가 말한 기능이 있는데 모르는 거라면 좀 알기 쉽게 만들던가 해야하는부분인거 같아요 ### 5/5 — 유용함 *2025-02-19* 간식 섭취를 건강하게 관리할 수 있는 유용한 앱입니다. 간식 시간을 기록하고, 그에 대한 정보를 체크하는 기능이 정말 편리해요. 간단한 인터페이스와 알림 기능 덕분에 간식 관리가 쉬워졌고, 나의 건강을 좀 더 잘 챙길 수 있게 되었어요. 꾸준히 사용하면서 목표를 달성하는 재미도 있습니다. 정말 유용하고 실용적인 앱이에요! **Developer response:** 안녕하세요 창섭이님! 좋은 리뷰와 칭찬 정말 감사합니다ㅠㅠ 앞으로도 간단은 더욱 정진해 더 좋은 서비스로 보답하겠습니다!! 행복하세요!! ### 5/5 — 추천 좋아요 *2025-02-18, version 3.227* 식단을 하면서 체중변화를 볼 수 있어서 단식 기록 뿐 아니라 여러가지 변화를 체크하고 확인 할 수 있어서 좋았습니다 무료도 좋지만 유료전환으로 사용 할 수 있는 것들이 좋았어요 다이어터들에게 쓰기 훌륭한 앱 같습니다 기간별 차트 보기도 편하고 잘 사용할 거 같아요 어려운 기능말고 다 쉽게 필요한 기능들만 갖춰 있는 느낌이라 다이어트 어플로 훌륭한거 같습니다! ### 5/5 — 다이어트하면서 체크하기 아주 좋아요!!! *2025-02-06* 기존에도 간헐적 단식을 계속 했었는데 그때는 기록이고 뭐고 없이 그냥 16시간 공복유지만 하는 것만 신경썼는데 이 어플을 사용하고는 시간관리뿐만 아니라 식단. 운동. 수분을 관리하면서 체크를 할 수 있어서 너무 좋은거 같아요 식단도 그냥 내가 먹은 거 사진으로 찍으면 칼로리도 계산해주고 다이어트하면서 도움을 받을 수 있어서 너무 좋은 어플인거 같아요!!!!!👍🏻 **Developer response:** 안녕하세요 우선 좋은 리뷰남겨주셔서 감사해요~~ 항상 더 노력하는 간단되겠습니다😊😊 행복한 한해 보내세요!! ## Frequently asked questions about InterFasting ### What does SimFast do?
