### 1/5 — AIが使えない

*2026-10-14*

とにかくイライラする。AIにスケジュール送っても理解されず
私が間違えてるの一点張り、AIが自動入力してくれるから楽だと思って入れたのにそれすらしてくれないなら他のスケジュールアプリと変わらない
あとAIの口がなぜか悪い。人をイライラさせるのに向いているアプリだと思います

### 2/5 — Không sử dụng được app

*2026-10-01, version 3.23.2*

Tải về thành công nhưng vào đến bên trong app thì không ấn được bất kỳ mục nào, chức năng nào luôn.

### 5/5 — 不同裝置同步

*2026-09-30, version 3.23.1*

使用體驗不錯，不同裝置如電腦、手機、平板能同步的話更棒（還是我沒找到）
