This is the best of all the calendar apps

I’ve tried all the calendar apps, they all have pros and cons. But for me this is the best, really the only app that does exactly what I want. It lets me visualize my life and my work exactly how I want to.

いい手触りです

手触りよく、一覧性が高いカレンダーアプリで、ここ数年ずっと愛用させていただいております。
ただ一点惜しいのが、繰り返しスケジュールの最後の予定を編集すると、それまでの予定も全て書き変わってしまいます。そこ以外本当に素晴らしいので修正いただければ幸いです。

資料全都不見了

用好幾年了，工作、生活全都記錄在上面，覺得很好用很方便，但今天打開竟然所有資料都沒了，變成初始設定，整個超崩潰，拜託看有沒有方法可以把資料找回來。
