「ToDoに書いた瞬間、なぜか安心してしまう。」 その安心感が、実は先延ばしの入り口です。DuesDayは「書く」ことと「終わらせる」ことを分けて考え、書いたその先――実行まで一緒に進むためのToDoアプリです。 ■ 毎朝、カードを4方向にスワイプするだけ 「今すぐ」「数分後」「今日中」「それ以外」。タスクカードを4方向にスワイプして仕分けるだけで、今日やることが自然と整理されます。難しい優先順位付けは不要です。 ■ 先延ばしを可視化する 何度も後回しにしているタスクは、炎のアイコンと回数バッジで一目でわかります。見て見ぬふりをさせません。 ■ タイムプランで時間に落とし込む 「今すぐ」「数分後」カテゴリのタスクを時間枠に自動配置。連続フォーカスモードで集中し、5分休憩を挟みながらこなしていけます。 ■ 続ける力を後押し ストリーク(連続達成日数)、ストリーク復活シール、レベルアップ、週間チャレンジなど、続けるほど手応えを感じられる仕組みを用意しています。 ■ ホーム画面・ロック画面ウィジェット、Live Activity アプリを開かなくても今日のタスクが確認できます。フォーカス中はLive Activityで残り時間を表示。 ■ プライバシーに配慮 アカウント登録不要。データは端末内で完結します(AI機能は今後のアップデートで追加予定)。 利用規約: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
