Frequently Asked Questions

3 answers
Will the timer play a sound?

No. The current implementation provides a visible completion status, not an audio alarm.

Can I enter minutes directly?

The field is in seconds. Multiply minutes by 60; ten minutes is 600 seconds.

Will it alert me after I close the tab?

No. Closing or refreshing loses this session. Device sleep and background throttling can also delay display updates.
