This is a timer that lets you visually check the remaining time. The pie chart gradually disappears, and when it completely disappears an alarm will sound. The time can be set from 1 to 60 minutes You can measure the time exceeded by changing the settings. This can be useful for studying for exams, etc. Please give it a try.
