Life Hack Reminderは、「今の自分に本当に効くライフハック」だけを、忘れず・しつこくなく思い出させるためのアプリです。 人生で大事なことほど、忙しくなるとすぐ忘れてしまう。 ToDoや名言のストックではなく、"自分専用の言葉・コツ・型"を「思い出せる形で育てる」ことに特化しています。 【3つのコンテンツ】 ・Life Cards(モチベ・格言・決意) 画像+短い言葉で構成される「刺さるカード」。 通知をタップすると、画像と言葉をドーンと表示して、気持ちや視点を上げます。 ・Nudges(人生のコツ・注意喚起) 「慌ててる時ほど呼吸を深く」「会話で焦ったら一呼吸」など、 日常で忘れがちなコツを一行メモとして保存できます。 ・Playbooks(状況別の型・攻略手順) 「こういうときはこう動く」という行動の型を、最大7ステップの手順として整理。 詳細メモで背景やポイントも書き留められます。 ※この3つは機能の違いではなく、「思い出させる」という同じ目的に対する表現の違いです。 【思い出させ方】 ・ローカル通知(毎日9:00/14:00) 朝と昼過ぎの1日2回、その日の1枚を端末内のローカル通知でお届け。 通知をタップすると、該当するLife Card/Nudge/Playbookの詳細画面がすぐ開きます。 ・反応で「育つ/退役する」仕組み 表示のあとで「役に立った?」と短くフィードバック。 YESが多いものは定期的・長期で出続け、NOが多いものは表示間隔が伸び、やがて削除/退役の候補になります。 「溜めるほど偉いメモ」ではなく、「今の自分に効くものだけが残っていく」ように自動で入れ替わっていきます。 【その他】 ・データはすべて端末内に保存され、サーバーには送信されません。 ・ライフハックを増やすより、「今の自分に合う少数を入れ替えながら育てていく」思想で設計されています。 忙しい毎日の中でも、「大事だと思っていたこと」を自然に思い出し直せるように。 Life Hack Reminderで、自分だけのライフハックを少しずつ育てていってください。
Calm Commit

Are you tired of endless to-do lists? Calm Commit is a gentle task management app that helps you choose the one thing that matters most today and keep it visible on your Home Screen. Instead of trying to manage every task perfectly, focus on the one thing that would make today feel worthwhile. If you can finish it, today is a good day. Your Daily Commitment Each morning, choose one thing you want to focus on most. For example: - Finish the first draft of a proposal - Submit presentation materials - Clean your room - Make plans with your family - Study for just 30 minutes Write down the one thing that would make you think, “If I finish this, today will be great.” When it is done, simply tap the completion button. Calm Commit gives your day a clear focus and makes it easier to feel a small, satisfying sense of progress. Home Screen Widgets Your daily commitment can be displayed as a Home Screen widget. Even without opening the app, you can see what matters most today every time you look at your phone. On busy days, it helps you avoid getting swept away by notifications and distractions, and gently reminds you what you decided to care about today. Widget Memo Separate from your daily commitment, you can also place a free memo on your Home Screen. Use it for shopping lists, things to bring, appointments, quick notes, or anything you do not want to forget. For example: - Buy eggs - Bring an umbrella - Call at 10:00 - Take out the trash tomorrow It works like a quiet sticky note for your phone’s Home Screen. If-Then Habits Habits are hard to build with willpower alone. With Calm Commit, you can create habits in an If-Then format: “If this happens, then I will do that.” For example: - After brushing my teeth in the morning, drink a glass of water - Before starting work, check today’s commitment - After lunch, walk for five minutes - Before going to bed, prepare for tomorrow By deciding when and what to do in advance, it becomes easier to take action naturally. Streaks When you check off a habit, your streak grows. Not like a flame burning intensely, but like a quiet wave that keeps moving forward. Calm Commit helps you record small daily wins with a calm, gentle feeling. Notes Calm Commit also includes a simple notes feature. Write down thoughts, shopping lists, work notes, ideas, or anything else you want to keep. You can use it as a simple notebook, or as a supporting space for your daily commitment. Why This App Was Created Calm Commit was inspired by the book Task Management for People Who Never Have Enough Time. The app focuses on the most practical parts of the book’s approach: choosing one daily commitment and building habits with If-Then planning. It is not meant to help you do more and more forever. It is designed to help you decide what really matters today, complete it, and end the day feeling good. Recommended For People Who - Feel tired of ever-growing to-do lists - Could not stick with other task management apps - Want to decide the most important thing each morning - Want to remember important tasks from the Home Screen - Want to place simple memo widgets like sticky notes - Want a habit tracker that does not feel too strict - Care about work, but also want to value time with themselves and their family Premium Premium makes Calm Commit more comfortable to use. Premium includes: - Ad removal - Unlimited notes - Unlimited habits - Photo backgrounds - Customization features such as water surface themes Monthly, yearly, and lifetime plans are available. Choose the one thing that matters most today. Keep it in sight. Finish it, and end the day feeling good. “If I finish this today, today will be great.” Make that one thing your commitment for today.
