About this tool
Set hours, minutes and seconds — or tap a preset — and the timer counts down in your browser tab. It keeps correct time even if the tab is throttled, because the remaining time is computed from the clock rather than from tick counting.
Questions & answers
- Does the timer keep running if I switch tabs?
- Yes. The remaining time is derived from the system clock, so a background tab that stops rendering still shows the correct value when you come back.
- Will it make a sound when it finishes?
- It plays a short beep if you leave the sound option on, and the page title changes so you can see it from another tab.
- Does this tool send my data to a server?
