1,440 minutes in a day. Are you truly making the most of your time? You start with determination: "I'm going to finish everything today!" But before you know it, it's night. Another day of procrastination... Ready to break free from this cycle? ◆ Do any of these sound familiar? ① Before you know it, the day is over ② You keep putting off important tasks ③ You set goals but can't achieve them, losing motivation ④ You're bad at time management and always feel rushed ◆ 1440task solves the "3 Major Time Management Challenges" ① [Visualizing Time Limits] Real-time remaining time display Countdown display until bedtime. The urgency of "Only ○ hours left!" prevents wasted time. Your time management awareness will change dramatically. ② [Simplified Task Management] No carry-over to next day rule Incomplete tasks are automatically reset. Free yourself from "guilt over unfinished tasks" and develop realistic goal management of "only what you can do today." ③ [Maximizing Focus] Display only immediate tasks Don't think about the distant future, just focus on today through the day after tomorrow. Task management becomes simple, and you can maintain motivation by accumulating small achievements. ◆ Why does 1440task work? The reason other apps failed was "overly complex features" and "unrealistic goal setting." 1440task is different. Simple × Real × Achievable These three elements help you naturally develop time management habits. Why not turn your limited 1,440 minutes into more valuable time? ◆ Especially recommended for: ・People who couldn't stick with other task management apps ・People who want to escape from days of being rushed ・People who want to build successful goal achievement experiences Starting today, your 1,440 minutes will change. ◆ Premium Plan Information No monthly or annual fees - with a one-time payment, you can permanently use the "Tomorrow/Day After Tomorrow feature" and "Ad-free feature." ◎ "Tomorrow/Day After Tomorrow Feature" A function that lets you plan not just for "today" but also for "tomorrow" and "the day after tomorrow." This feature is for people who want to list tasks 1-2 days in advance rather than thinking about today's tasks on the same day. ◎ Ad-free Feature A day has only 1,440 finite minutes. This feature is recommended for people who don't want to spend even a few seconds viewing ads for task achievement. ◆ We recommend the Premium version. While the free version is sufficient for your task management needs, we recommend using the Premium version. While you'll basically organize today's tasks "today," there will surely be times when you want to jot down what to do "tomorrow" or "the day after tomorrow." When you use the Premium version in such situations, you'll truly appreciate the convenience of this extended functionality. It's also comfortable without being distracted by ads. Of course, you can fully experience the convenience of this app with the free version as well. Manage your tasks effectively and have a fulfilling day! 【Terms of Use】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
