The countdown is anchored to a finish time, so it stays exact even if the tab is in the background. Press Test sound once so the browser lets audio play. Space starts and pauses, L takes a lap, R resets.
Thirty five minutes suits a roast chicken stage, a moderate gym session, or an exam section with a little reading time built in.
For anything you will repeat, give the timer a label first. Labelled timers appear in the Recent row so you can start them again with one tap.
A free online timer, stopwatch and countdown clock that runs entirely in your browser. No account, nothing to install.
It keeps working offline once loaded, and you can add it to your home screen like an app. Your settings stay in your own browser.
Press Voice control and allow microphone access, then speak normally. Your speech is handled by your browser's own speech service, and nothing is stored by this page. Allow the microphone once and switch this on once, and it stays on as you move around the whole site, in this tab or a new one. It switches itself off after an hour of not being used. The button always shows whether it is listening, and tapping it stops it for good.
Two thousand one hundred.
Give it a label before you start and it appears in the Recent row, ready to run again with one tap. Recent keeps your last five timers.
It sits between the twenty five minute Pomodoro and the fifty minute block, which suits people who find one too short and the other too long. Pair it with a real break rather than a glance at your phone.
