Frequently asked questions
Switch tabs and the time will stop?
No, it is calculated based on real time instead of counting frames. So it updates to the correct time when you return to the page.
Do I have to enable notifications?
No. Alert sounds can be enabled without requesting permissions. The screen notification section is optional and the browser will ask for permissions first.
