Alarm sound plays when it hits 0. Works offline after first load.
Classic Pomodoro: focus, short break, repeat. Alarm at each phase end.
Run multiple simultaneous countdowns (great for cooking, workouts, or classrooms).
This online timer combines a fast countdown timer, a stopwatch with laps, and a simple Pomodoro timer for study sessions. People use timers daily for workouts, cooking, presentations, exams, and classroom activities—so a lightweight page that loads quickly is perfect for repeat visits and bookmarks.
Set a countdown in minutes and seconds, start it, pause it, and reset anytime. The progress ring gives you a quick “at a glance” view of how much time is left, and when the timer ends, your browser plays an alarm using the Web Audio API—no external audio files or libraries required. For the stopwatch mode, you can record lap times for intervals and training. In Pomodoro mode, the tool alternates between focus and break phases (default 25/5), with an alarm at each phase end.
Need more than one countdown? Use the multiple timers panel to run several timers simultaneously. Full-screen mode is included for presentations and classrooms so the display stays readable from a distance. Everything runs locally in your browser and doesn’t store your data.
