About the Countdown Timer tool
Set hours, minutes and seconds and press start. The timer shows progress, supports pause and reset, and beeps when it reaches zero.
It needs the tab open to run. If you need an alarm for hours away, the countdown-to-date tools or your phone’s clock app are more reliable.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
