How this timer works

Choose a preset to begin immediately, or enter a duration and press Start. Pause keeps the exact time left; Reset returns to the chosen duration. No account or saved selection is needed.

The display recalculates from the device clock when a suspended tab resumes. Browsers can delay sounds and updates in background tabs, so keep the page open for an important alert.
