### 3/5 — 特に編集機能が使いにくい

*2024-10-02, version 2.4*

電車の乗車時間を記録するのに使用しています。古いカテゴリを削除しようとしたところ、全てのカテゴリが削除され保存してたデータも消えてしまいました…。
表示がわかりづらく慣れるのに時間がかかるアプリなので、まずは消えてもいいような計測データやカテゴリで使い方を練習することをお勧めします。

### 2/5 — 良いアプリを見つけたと思ったけど残念

*2021-10-28, version 2.2*

アプリ起動後すぐに記録開始でき、集中した時間を分類してくれるシンプルな作りで最初は気に入っていたが、どうも動作が安定しない。

ドラッグ&ドロップすると項目が消えてしまい記録が取れない。せっかく3時間近く集中したのに残らないなんてことが多発。嫌になってきた。このままじゃ使えない。

### 3/5 — 1時間以上のタイマーが作れない

*2020-10-02, version 2.0.1*

スライドバーで任意の時間を設定する画面で、タイマー自体は00:00:00と、99時間まで設定できそうな感じなのですが、スライドバーは59分までしかなく、1時間以上の設定ができません。
あと、タイトルが「無効」のまま変更できません、改善よろしくお願いします。

### 5/5 — サポートサイト

*2019-02-28, version 1.1.1*

サポートサイトが見つかりません。
それにlogを15分に設定していても、通知が来ません。改善お願いします！
