Frequently asked questions
Will the timer keep running if I switch tabs or lock my phone?
Yes. The timer stores the exact moment it should end and compares it with your device clock, so it is correct the moment you come back. Browsers may delay the alarm sound slightly while a tab is in the background.
Why didn't I hear the alarm?
Check that the timer is not muted, your device volume is up and the phone is not in silent mode. Browsers only allow sound after you have interacted with the page, which pressing Start does.
What is the longest timer I can set?
Up to 99 hours, 59 minutes and 59 seconds.
Do I need to sign up or install anything?
No. The timer works in any modern browser on phones, tablets and computers. Your settings stay on your device.
