### 4/5 — こういうアプリ欲しかった!!

*2024-07-19, version 1.1.1*

朝のルーティーン管理に使ってます。 秒数まで表示されるのありがたい! 強いて言えば、 1.Todoに日付や時刻を設定したら、デフォルトで通知が設定される機能があると嬉しいな。iPhoneのリマインダーみたいな。2.音の種類や長さ設定

### 4/5 — 締め切りまでの具体的な日数がわかりづらい

*2024-07-18, version 1.1.1*

カウントダウンが時間単位のみだと細かすぎて逆にどのくらい猶予があるのかわかりづらく、「まだ時間がある」という意識が残ってしまいます。
日数単位でのカウントダウンへの変更もできるようにしてほしいです。

### 5/5 — 求めてたのはこういうのだ！！

*2023-07-21, version 1.1.1*

でも使っててこうしてほしいな〜って要望がでてきたので一応書いておきます １、カウントダウンの秒数表示の変更(私は秒数までは表示されなくてもいいかな) ２、文字の大きさと色の変更(変えれたらよりわかりやすくていいかな) ３、通知音をiPhone内の好きな音楽や通知音に変更(音の違いでわかりやすくしたい) よかったらお願いします。

### 4/5 — 不具合報告

タスクを期限前に終えたので１年後に直そうとしたところ反映されなかった−1点

システムは素晴らしいので今回は減点は1点とします。
