An unusual clock app that allows you to be more productive by making friends with "time". The design is highly customizable. Also ideal as a table clock. [ Increase Free Time ] Why is there only 24 hours a day? This app allows you to change the length of time. If you set a day to 26 hours, the length of one hour will be 5 minutes shorter than usual. By putting this clock in a place where you can see it, you will be able to spend your time efficiently in a natural way. After 24 hours, you will get 2 hours of bonus time. This means that the short times you save will be combined to make more meaningful time. [ Take Frequent Breaks ] Proper breaks are essential for meaningful use of time. You need to stand up, stretch and hydrate regularly. If you set 1 hour to 65 minutes with this app, you can take a 5 minute break every 60 minutes. You can also ring the chime every hour, which makes it easier to take a break even if you are absorbed in the work. [ Fits Your Lifestyle ] Do you have the habit of advancing the clock in your room? This is usually not possible with a “too accurate” clock on a smartphone. With this clock app, you can advance or delay the display time. If you advance it by 5 minutes, you will be able to avoid being late. You can also set the start time of the day. For example, you can manage working hours by setting the business start time to 00:00. When traveling, it's easy to set the clock to local time. [ Also as a Table Clock ] Of course, this app can also be used as an ordinary clock. It has a big, easy-to-read digital display, so it's a good idea to use it as a table clock when your iPhone or iPad is on a charging stand. You can change the design of the clock face by setting the font and background. Enjoy customization. [ List of Functions ] Clock: - Advance or delay the clock. - Set the start time of the day. - Set the hours per day, minutes per hour, and seconds per minute. - Accelerate the clock up to 24x. - Sound the chime every hour/minute/second.

Kigen Tasks is a semi-task management scheduling app designed to help you enjoyably meet deadlines. Kigen (期限) means due/ deadline in Japanese. There is a reason why I wrote "semi". This app is a little too simple to be called a scheduling app. All you need to enter is the title, a quick note, the due date, and the importance of the task. It is also very simple to use. When a task is completed, you just record it as completed. Completed tasks will disappear, but uncompleted tasks will stay on the list until they are completed, regardless of the passing days. Other features include ・Background colours as a due status indicator. When the background colour is green, it is safe! If you have an appointment within 5 days, it will turn yellow, for the next day's task it will turn orange, and on the same day or when an appointment has already passed the due date, it will turn red. ・Punctuality level If you complete a task earlier than the set due date, you will move up a level! On the other hand, if you miss the deadline, you will be downgraded. There is nothing special that happens just because the level is raised, but it is a nice feeling to see the number go up, so I hope you will make use of it to motivate yourself. ・Notification function Notifications are sent one week, five days, three days, two days, the day before, and the day of the deadline! This is why this app is too simple to be called a schedule app, instead, it is an app that was created with the focus on how to help you keep up with your deadlines simply and enjoyably. No more last-minute deadlines!
