About Kigen ~ penguin task tracker
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!
