Start it, forget it, the alarm reminds you
The most useful timer is the one you start without thinking. One click on a preset (1, 3, 5, 10, 25 min) or a free h/min/s entry, and off it goes. At zero, a real alarm rings on a loop until you stop it — impossible to miss.

A few classic uses
- Cooking: 3 min for a soft-boiled egg, 10 min for al dente pasta.
- Sport: planks in sets, timed rest between exercises.
- Work: focus sessions, enforced breaks for your eyes.
- Kids: screen or play time, a 2-minute tooth-brushing.
The countdown targets a fixed end time: it stays right even if the tab goes to the background. Everything is local, no data leaves your browser.
Frequently asked questions
Does the alarm ring if I leave the tab?
Yes: the sound is generated by the browser and fires at the deadline even in the background, as long as the tab isn’t closed. The countdown also shows in the tab title, visible at a glance among your open tabs.
Why does the timer stay accurate?
It targets a fixed end timestamp and recomputes the remaining time on every tick. Even if the browser throttles inactive tabs, the ring time stays exact — no accumulated drift.
Do I need to allow sound?
Browsers require an interaction (a click) before playing audio. Since you start the timer by clicking, permission is granted: the alarm will ring. Just check that the volume isn’t muted.
What’s the difference from a stopwatch?
A stopwatch counts time upward (measuring a duration); a timer counts down to zero from a set duration (being alerted at the end). For a rhythmic work session, see also our Pomodoro timer.
