Questions
- Does the 5 second timer keep running if I switch tabs?
- Yes. It counts against the real clock, so switching tabs or returning after a browser pause shows the correct remaining time. Keep the tab open for the finish sound and notification.
- How do I start the 5 second timer?
- It loads ready to go — just press Start (or the spacebar). It will play the selected sound when time is up and can show a notification if notifications are allowed.
