데이터 수정은 불가능한가요?

안녕하세요. 전날 습관 체크를 못해서 다음날 하려 하는데 데이터를 수정할수는 없는건가요?

습관형성은 이앱으로

미니멀리즘의 끝판왕인 습관앱. 단순한거 좋아하는 사람에겐 goat 앱. 직관적인 형성가능. 연속일기능도 좋습니다. 구독료가 진짜 싸서 좋아요.

안드로이드 버전은 안나올까요? ㅠㅠ

교사입니다.
학생들과 학급 특색 활동으로 사용할 습관형성 어플을 칮고 있던 중 66 days를 발견하고 마음에 쏙들어 아이들에게 권했는데 아이들이 안드로이드에는 없다고 하더라고요. 그래서 다른 어플 엄청 찾아봤는데 마음에 쏙 드는 것은 이것 뿐입니다. ㅠㅠ
안드로이드 버전도 만들어 주세요.. ㅠㅠ

간결한 ui , 함축적인 기능

간결하면 리스트를 기록하기가 좋습니다.
