【About Just Start】 We believe that "Starting" is the greatest action of all. Just Start is not just a timer; it’s your launchpad to beat procrastination. We stripped away the clutter so you can do one thing the moment you open the app: Act Now. 【Why Just Start?】 1. A Companion from the Stars: Laika Remember Laika, the first dog in space? She didn't disappear; she traveled to your phone. When you focus, Laika waits by your side on the screen. Whether you're studying late or working early, she is there. It’s not just a timer; it’s a warm, silent guardianship. 2. Pro Features Unlocked (Yes, Free) We believe your growth data belongs to you. No paywalls for self-reflection. 3. Unlimited Categories: Coding, Reading, Meditation—create as many tags as you need. Free. 4. Full History Stats: Your every minute counts. Access all history records, duration stats, and trend charts without paying a cent. Visualize your achievements. 5. Starlight Mode: A Connection Across Time Focusing can feel lonely, but not here. When you start the timer, you will see the glimmering starlight left by others who have traveled this path before you. Just like looking at the night sky, these lights are echoes of past efforts from people around the world. It’s a subtle "cloud companionship" that tells you: someone else has worked hard right here, just like you.

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。
