The first-place schedule management app in the App Store in Japan is a free app that helps users manage their daily schedules using a 24-hour pie chart. It offers various features such as total time calculation and graph transitions to visualize and analyze daily activities. Users can enter their schedule for the next day, and the app automatically analyzes and displays the total time and bar graph, allowing them to reflect on their daily schedule and make improvements for a well-balanced day.

The app is equipped with all the necessary functions for schedule management, including automatic total time calculation, bar graph transitions, diary and goal registration, and push notification reminders. It stands out from similar apps with its free usage fee, easy one-tap schedule registration, and the ability to visualize schedules as a pie chart. Users can add multiple schedules, view the total time spent on each activity, and track their progress towards goals. The app also offers over 100 color variations for customization and allows schedules to be registered in 5-minute increments for detailed planning.

While the basic functions of the app are available for free, there is a premium plan that offers additional benefits such as ad removal, widget usage, and priority support. The premium plan is available on a monthly or yearly basis, with prices of USD 4.49 per month or USD 44.99 per year. The app provides automatic renewal after the free trial period, but users can cancel the subscription at any time. For inquiries, users can contact the app's support team via email.
