About the timer with alarm

The alarm plays a repeating beep pattern generated in the browser, so it works offline and loads instantly. Use the volume slider to set how loud it should be.

Browsers only allow sound after you interact with the page, so press START at least once before leaving the tab. If you grant notification permission, you will also get a system notification.
