5/5그동안 써본 달력
중에서 가장 마음에 드는 달력입니다. 복잡하지 않고 즉시입력되고 한눈에 볼 수 있어 좋습니다. 감사드립니다.

4/5완전 편리..
항상 날마다 종이에 적을 필요없이 핸드폰으로 적을수있다는것부터 너무 만족중인데, 알람 시간 설정해두면 알아서 그 시간에 일정이 떠서 너무 편리함. 원래는 노숙자처럼 집에만 박혀있는데, 요즘 이 앱으로 해야할거 다 적어두고 하나씩 하니까 날이 너무 빨리가더라.. 요즘에 운동도 시작하는데 항상 언제 시작할지 알람이 와서 굳이 핸드폰 알람시계 그런거 설정 안해도됨. 이거 한번하면 뭔가 사람이 계획적이게 되고 계속 뭐 적고싶어짐..
