### 5/5 — いい手触りです

*2026-07-05*

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。

### 1/5 — 資料全都不見了

*2026-06-11, version 1.7.6*

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。

### 5/5 — 很好用

*2026-03-24, version 1.7.6*

很好用的日曆，不過有少少提議，可否再增加多一點顏色可以再分多一點細項

### 3/5 — 背景の色

*2026-02-13, version 1.7.6*

背景の色はなぜ暗い色しか無いのでしょうか？白とか無いのでしょうか？

とても悲しいです。。
