01
What this one is for
A 45 minute timer is a class. School periods, gym sessions, a half of football and most therapy hours all land here, which suggests forty five minutes is about as long as attention holds.
It is a good work block if twenty five feels like it ends just as you get going. Set it, do one thing, take a real break after.
Start with Space. The tab title shows what is left, the screen stays on, and the alarm beeps at zero.

How it runs
Counts down 45 min, then beeps. Press Start, or hit Space. The digits turn green while a work block runs and grey on rest.
Sound is on by default: a rising pair for work, a falling pair for rest, a tick for the last three seconds and a three-note finish. Mute with the speaker button. The screen stays on while the timer runs and the tab title shows the time left.
Change anything in Settings under the timer. The last setup you used on this page is remembered in your browser.
Questions people ask
- Is 45 minutes a good study block?
- Many people focus better in 45 to 50 minute blocks with a proper break after, rather than the shorter pomodoro cycle.
- Will it ring if the tab is in the background?
- The countdown never drifts since it is tracked from timestamps. The beep plays while the tab is open, or the moment you switch back to it.
- Can I change it to an hour?
- Yes. Edit the duration on the timer or open the 60 minute page.
- Do I need to sign up?
- No login, no install, and it works offline after the first load.
