How it works

The timer runs entirely in your browser — nothing is uploaded, there is no account, and it keeps working even if your internet drops. It keeps counting while the tab is open in the background, shows the remaining time in the tab title so you can glance at it from another window, and plays a beep plus a visual alert when time is up. You can pause and resume any countdown, and restarting a preset takes one click.

One honest limitation: if the tab is closed or your device goes to sleep, a browser timer cannot ring. For waking up use the online alarm clock; for measuring how long something takes, the stopwatch; for dates days or weeks away, the event countdowns.

Frequently asked questions

Does the timer keep running if I switch tabs?

Yes — the countdown continues in a background tab and the remaining time stays visible in the tab title. Keep the tab open and you will hear the beep at zero.

Will it still ring if my computer falls asleep?

No. Browser timers pause when the device sleeps or the tab closes. For wake-up use, set an alarm instead and keep the screen on.

Timer or stopwatch — which do I need?

Timers count down to zero (cooking, pomodoro, rest breaks); stopwatches count up from zero (races, tasks, experiments). We have both, plus an interval timer for repeating work/rest cycles and a stage timer for talks.
