How to use this tool
Enter a positive total duration and start the timer. Sound depends on the browser’s audio permission state, so test a short interval before relying on the audible cue.
Results and examples
One minute and thirty seconds sets an end time ninety seconds away. Remaining time is compared with the current clock, but a suspended tab or sleeping system can delay the completion notification.
Limitations
- Closing the tab, power saving and blocked audio can prevent a timely alarm.
- Do not use it as the sole reminder for safety-critical timing or essential medication.
