一日に、自分に、一つだけ約束する。 これは、自分との約束を守る力を鍛えるためのアプリです。 ◆ たった一つのシンプルな習慣 朝、自分に一つだけ約束を書きます。 「今日、私は自分に約束する:___」 ただ一行。 夜、その約束と向き合います。 守れたのか。守れなかったのか。 ○か×を、自分で押します。 たったそれだけ。 ◆ 4つの記号が、あなたの日々を記録する ○ 守れた × 守れなかった △ 向き合わなかった(判定せず日付境界を越えた日) — 約束しなかった日 これらの記号が、履歴に静かに積み重なっていきます。 それは、あなたと自分の関係の、嘘のない記録です。 ◆ 取り消せない 一度確定した判定は、後から変更できません。 ゲームのようにリセットできない。 過去は、重い。 だからこそ、今日の一つの約束に、意味が宿ります。 ◆ 白と黒だけの、静かなデザイン 通知もカラフルなアニメーションもありません。 バッジも、連続記録のプレッシャーもありません。 ただ、あなたと、今日の約束と、向き合う時間だけ。 ◆ プライバシー完全保護 すべてのデータは、あなたのiPhone内にのみ保存されます。 外部に送信されることは一切ありません。 データ収集ゼロ、ネットワーク通信ゼロ、広告ゼロ。 ◆ こんな人に ・毎日の小さな積み重ねを大切にしたい人 ・自分との信頼を取り戻したい人 ・ミニマルで静かなアプリを好む人 ・シンプルな内省の時間が欲しい人 今日、あなたは自分に何を約束しますか。
