Countdown Timer

Set a countdown for any duration and receive an audible alert when time expires. The 25-minute Pomodoro preset supports the Pomodoro Technique — a time management method developed by Francesco Cirillo in the late 1980s that uses 25-minute focused work intervals separated by 5-minute breaks. Research on sustained attention and mental fatigue supports timed work sessions: cognitive performance typically declines after 25-50 minutes of continuous focus on a demanding task, making regular short breaks measurably more productive than uninterrupted long sessions.
