Common questions
How can I check the alarm sound before starting?
Press TEST SOUND. It plays the alarm without starting or changing the countdown, so you can adjust your device volume first.
Do I need to install anything or sign in?
No. The alarm sound is generated in your browser, and once the page has loaded, the countdown does not need a network connection.
Will the alarm ring if I switch tabs or my device goes to sleep?
Keep this tab open, your device awake and the sound on. Browsers may slow down background tabs, and power-saving settings can delay the alarm. It may not ring at all if the tab is closed or the device sleeps.
