「自分との約束、本当に守れていますか?」 KAKUGO(覚悟)は、あなたの覚悟に価値をつけて、達成した時に寄付として社会に還元する—— そんな「自分への約束アプリ」です。 ▼ KAKUGO の使い方 1. 目標を決める 例:30日間、毎日30分の英語学習。 2. 期間と「1日あたりの価値」を決める 例:30日 × 500円 = 15,000円。 この金額は、達成したときに寄付として社会に還元する予定額です。 3. 覚悟を立てる 立てた覚悟は、編集できません。 「決めたものは動かさない」——それが KAKUGO のコア価値です。 4. 達成したら、寄付で形にする 達成画面から、READYFOR・Syncable・カタリバの 寄付プラットフォームへ進めます。 ※ アプリ内決済は行いません。寄付先サイトで直接お手続きください。 ▼ なぜ「価値型」なのか 罰金型の習慣アプリは、続かなかった時に自己嫌悪を生みます。 KAKUGO は逆に、達成したご褒美を「自分の外」に出すことで、 覚悟を守れた瞬間を、社会への小さな貢献に変えます。 ▼ 機能(フェーズ1) ・覚悟の作成(目標・期間・1日あたりの価値) ・進捗の可視化(経過日数・残り日数・達成率) ・達成画面と寄付先への外部リンク ・X(旧Twitter)への達成報告(テンプレ付き) ・データはすべてあなたの端末内に保存。サーバーへの送信は一切ありません ▼ 開発者より このアプリは、「非エンジニア以上エンジニア未満の30代パパ」が制作した小さなプロダクトです。 完成までの過程は X( @EngineeringPapa )で公開しています。 あなたの覚悟が、誰かの未来につながりますように。
