About the Online Timer & Stopwatch

Sometimes you just need a timer — for the pasta, a workout interval, a focus session, a quick game round, or a kid's turn. This one opens instantly, sets in a tap, and rings when the time's up, with a stopwatch on the same page for when you need to time something instead of count it down. No app to install, no account, and nothing tracked.

It runs entirely in your browser, so once the page has loaded it keeps working even offline, and the tab's title shows the remaining time so you can see the countdown from another tab.

Common questions

How do I set a timer for 10 minutes?

One tap on the 10-minute preset (or type any custom time) and the countdown starts, ending with a proper alarm. The digits are sized to read from across the kitchen or classroom.

Does the timer keep working if I switch tabs?

Yes, and this is rarer than it should be: timing is anchored to the wall clock, so the countdown stays accurate even when the tab is buried in the background, where most online timers quietly drift.

Does it have a stopwatch with laps?

Yes. The stopwatch side counts up with lap recording, for workouts, races, timed reads, and anything else worth clocking.

Will the alarm sound if my volume is on?

Yes, a clear alarm plays at zero. Keep the tab open and the volume up, and the end of the timer will not be a matter of opinion.

Is this timer free, with no ads interrupting it?

Free, no account, and nothing interrupting the countdown. It also keeps working offline once the page has loaded.
