About this timer
The countdown keeps accurate time even if your browser throttles background tabs — it tracks the target end moment rather than counting ticks, so switching tabs will not make it drift. When time is up it plays a triple beep (your device must not be muted) and the remaining time shows in the tab title so you can see it from another tab.
Does it work offline or if I close the tab?
The timer lives in this page: it survives tab switches and brief network drops, but closing the tab stops it. For alarms that must fire with the screen off, a phone's built-in clock app is the right tool.
