Questions & answers
Will my screen go to sleep during the lesson?
No – while the timer runs it keeps the screen awake in supported browsers.
Are there ads in full screen?
No. Full screen shows only the timer.
Can I add it to Google Classroom or my class site?
Yes, use “Embed a timer” in the Tools menu, or share the link.
