### 5/5 — 그냥 이앱이최고임

### 5/5 — Simple isn’t always bad

*2025-03-10*

I get easily distracted and have come to realize that I NEED a check list that I can quickly refer to. Well full time mom and I don’t have time to write so love this app hope the ads go away

### 3/5 — 도와주세요

*2025-02-28*

제가 두달간 호주에 다녀왔는데 그기간동안 작성한 내용들이 한국에 오니 다 지워졌습니다. 복구를 간곡히 부탁드립니다. 호주에서는 한국에서 기록된게 안보이던데 왜 그런건가요?

### 5/5 — Checkbox

*2024-01-05*

I like it so far. Looking forward to explore it more in depth.

### 1/5 — Don’t rely on

*2022-06-10*

I lost everything when I had to delete and re-download because the screens are layered on top of each other.  Usually that fixes apps when there is a problem; however, all my stuff in my calendar is gone and I don’t see that I can get it back.  Do not rely on this app at all.  It has major bugs in it that do not go away.

### 5/5 — 안녕하세요. 이번 1.41 업데이트 이후 처음으로 문제가 생겨서 말씀드립니다~!

*2022-05-23*

1. 어떤 날을 클릭해서 Title에 할 일을 몇 줄 정도 적고 저장합니다. 2. 다시 오늘의 할 일을 확인하려고 누르면 화면이 아래로 내려가버립니다. (= 즉, 제일 위 Title에 써둔 오늘 할 일이 안보이고ㅠㅠ 날짜, 반복, 알람, importance, 메모만 보입니다.) 3. 이 문제 때문에 매번 할 일을 보려면 화면을 스크롤해서 올려야 하고 작성하다 보면 내려가 또 화면이 아래로 내려가 버리는 현상이 반복됩니다ㅠㅠ 몇 년째 잘 쓰고 있었는데 처음으로 문제가 생겨서 말씀드립니다. 이번 업데이트 후 이 증상이 생겼습니다. 후속 업데이트로 이번의 작은 문제점 살펴봐 주시고 해결 부탁드립니다. 혹 시스템상 수정이 어렵다면 아쉽지만 제가 다른 앱을 알아봐야겠지요ㅠㅠ 늘 감사드립니다^^

### 2/5 — 두개로 겹치는 오류

*2022-04-12*

앱 깔고 며칠 잘 되더니 뭐 입력하거나, 저번달꺼 보려고 하면 두개로 겹쳐서 암것도 안되요

### 5/5 — 가입신청

*2022-02-22, version 1.40*
