Everything runs locally in your browser — there is no server to trust with your data and nothing to configure. Open the page and the tool is ready.

Common durations are one tap away as preset buttons. Need something else? Enter an exact duration and start the countdown immediately.

When the countdown ends you get a clear beep, and you can restart the same duration with a single tap on Reset.
