このアプリでは、タイマーを最大5分までしか設定できません。 なぜか? 一度始めた行動は、続けやすくなるから。 「1分だけ」のつもりが、気づいたら5分、10分。 大事なのは「長くやること」ではなく「始めること」です。 — ■ 3日坊主は「意志力」の問題じゃない 習慣が続かない本当の原因: ・いつやるか決まっていない  「毎日やる」だけでは、いつまでも始まらない ・何をするか具体的じゃない  「筋トレする」では、何をどれだけやるか毎回迷う ・目標が大きすぎる  「毎日30分」は、3日目に負担になる 「1分の習慣」は、この3つを仕組みで解決します。 — ■ 3つのシンプルな仕組み 【if-then planning】 「朝コーヒーを淹れたら、ストレッチをする」 いつ・どんな状況で・何をするかを事前に設計。 心理学者Gollwitzerの研究で、目標達成率が2〜3倍になることが実証されています。 【3ステップ分解】 やることを3つの具体的なステップに分解。 「次に何をすればいいか」を考える必要がなくなります。 【1〜5分タイマー】 始めるハードルを極限まで下げる。 1分から設定できて、最大5分。それだけでいい。 — ■ 主な機能 ・if-then planning:「いつ・何を」を設計して通知でリマインド ・1〜5分タイマー:始めるだけ。あとは流れに乗る ・カレンダースタンプ:やった日がひと目でわかる ・完全オフライン:アカウント登録不要。データは端末内に保存 — ■ こんな方に ・何度も3日坊主を経験している ・習慣化アプリを試したけど、結局続かなかった ・やりたいことはあるのに、始められない ・「頑張る」以外の方法を探している — 頑張らなくていい。仕組みに乗るだけ。 あなたのペースで、1分から。
