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.
Studying in timed blocks works because it makes starting easy and finishing definite. Pick a length, work only on that one subject, and stop when the alarm sounds.
Label each block with the subject and it appears above the countdown and in the Recent row, so you can restart the same block with one tap tomorrow.
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.
Twenty five minutes suits most people starting out. Fifty minutes suits people who need longer to get into difficult material. Both are on this site as their own pages.
Only lightly. The last five labelled timers are kept in your own browser so you can start them again. Nothing is uploaded and there is no account.
