25 Minute Timer

Twenty-five minutes is the heart of the Pomodoro Technique, one of the most popular time-management methods in the world. Developed by Francesco Cirillo, the technique prescribes 25-minute focused work sprints followed by 5-minute breaks. This duration is backed by research on sustained attention and cognitive freshness. Beyond Pomodoro, 25 minutes works well for focused study sessions, practice instrument drills, and timed exam preparation. This free online timer keeps precise time using absolute timestamps, so you'll never lose seconds to browser throttling. An alarm chime signals when your sprint is complete.
