Predy is a study timer and planner that helps you start studying, stay consistent, and make your progress visible. Use a study timer, Pomodoro, stopwatch, or manual entry to track learning time and build a routine that lasts. In Predy, goals are organized as projects, with tasks and work logs contained within them. Tasks can be managed by project, priority, deadline, and estimated time, preventing work from becoming scattered. Because all work logs are tied to projects, progress accumulates automatically, making it easy to see where you stand. Estimating required time in advance also helps users realistically understand what it will take to reach deadlines, reducing failed plans. The first problem Predy tackles is “not being able to start.” Work tracking supports Timer, Pomodoro, Stopwatch, and manual entry, allowing flexible use depending on the task and mental state. StudyWithMe mode further lowers the barrier by creating a focus-friendly atmosphere with immersive visuals and ambient sounds. On days when starting feels hardest, AutoPilot is especially effective. With one tap, a 2-minute timer begins alongside a simple starter action, such as tidying your desk. After that, you naturally move into a focused 20-minute session. This uses behavioral activation—you don’t start because you’re motivated; you get motivated because you started—minimizing resistance and building momentum naturally. Predy is also designed to make you want to continue. Daily login and task completion bonuses grow with streaks, while rankings visualize productivity through multiple metrics such as project completions, focus level, efficiency, total work time, and consecutive days. Even “just one minute today” feels meaningful, often leading to longer sessions. Consistency is supported not by grit, but by structure. Progress is clearly visible through analytics that show work volume and time for today, this week, and this month. Seeing effort accumulate creates a sense of achievement and naturally leads to “Maybe I’ll do a little more.” Predy’s core differentiator is Prediction. Before working, users estimate how long a task will take and compare it with the actual result. Feedback at project completion helps clarify why estimates were off. Repeating this process improves planning accuracy, reducing deadline overruns. Predy doesn’t just manage tasks—it trains how to plan. Predy isn’t only for your best days. It’s for people who tried task management apps many times and couldn’t keep going. By lowering the barrier to starting, creating reasons to continue, and leaving visible proof of effort, Predy helps users try again. From “I have to push myself” to “I’ve already moved forward.” Predy is designed to make that state part of everyday life.

「3km走る」ではなく「15分走る」。 成果ではなく、時間を積み上げるだけ。 それが、習慣化タイマーの設計思想です。 ---------------- ほとんどの習慣アプリは「成果」を求めるので、調子の悪い日に達成できず、ストリークが切れて挫折します。 このアプリは、やる量ではなく「タイマーを最後まで動かしたかどうか」で達成を判定します。 出席することだけが、あなたに求められる唯一のこと。 毎日勝てるからこそ、続きます。 ---------------- 【こんな人におすすめ】 ・他の習慣アプリで挫折した経験がある ・『Atomic Habits』『習慣の力』に共感した ・派手なゲーミフィケーションに疲れた ・自分と静かに向き合える道具を探している ・「やる気」ではなく「設計」で習慣化したい ---------------- 【主な機能】 ・時間ベースのカウントダウンタイマー ・バックグラウンド・画面オフ中も時間は進み続ける設計 ・「私は〜する人だ」のアイデンティティ宣言を登録 ・「When I X, I will Y」形式の実行意図を設定 ・連続記録(ストリーク)と統計の可視化 ・決めた時刻にやさしく合図するキュー通知 ・習慣ごとに自由なカラーカスタマイズ ・今日やる習慣だけが並ぶ、ノイズのないホーム画面 ・ホーム画面ウィジェットで一目で確認 ・完全ローカル動作(外部送信なし) ---------------- 【行動科学のバックボーン】 アイデンティティ習慣(James Clear) 「目標」ではなく「なりたい自分」を主語にする。 実行意図(Peter Gollwitzer) 「いつ・どこで」を決めた瞬間、達成率は2~3倍に。 2分ルール 始めるハードルは「最初の2分」だけ下げればいい。 損失回避(Daniel Kahneman) 失う痛みは、得る喜びの2倍に感じる。 だから連続記録は強力に効く。 ---------------- 完璧より、続けること。 1%の積み重ねは、1年で37倍になる。 今日、その証拠を1つ積み上げましょう。 ---------------- プライバシーを最優先しています。 あなたの記録はすべて端末内に保存され、外部に送信されることは一切ありません。
