静岡中央高校　TODOTIME

This app combines task management and timer functions. It helps you work more efficiently by managing your daily tasks and being mindful of the time spent on each task.

In addition to a standard countdown timer, this app includes features such as the "Pomodoro Technique," which involves working for 25 minutes followed by a 5-minute break—a technique said to improve study efficiency. Other features include a daily habit mode where tasks are automatically reset each day, and a mode for one-time use where tasks are permanently disabled. There's also a streak function to boost motivation for habit formation. Its simple and easy-to-understand interface makes it easy to stick with, making it recommended for people who easily get bored or struggle to form habits.
