Countdown timer guide

A good timer should be visible, dependable and easy to control.

This countdown timer uses the current clock to calculate remaining time, helping it stay more accurate when browser updates are delayed.

Fullscreen focus mode

Fullscreen mode expands the timer into a distraction-free display suitable for classrooms, workouts, presentations and focused work.

Alerts

Sound, vibration and browser notifications can be enabled independently. Browser permission may be required before notifications are displayed.

Session history

Completed timers are saved locally so users can quickly repeat recent durations.

Frequently asked questions

Browsers may block audio before a user interaction or when the device is muted.

Can the timer display in fullscreen?

Yes. Use the Fullscreen button or press F. Browser fullscreen availability varies by device.

Is timer history uploaded?

No. Recent completed sessions are stored only in local browser storage.
