Frequently asked questions
Will the timer keep running if I switch tabs?
Yes. The countdown follows the clock, so it stays accurate in the background, and the time left is shown in the tab title.
How do I make the alarm louder?
The alarm uses your device volume. Turn it up and make sure the “Sound” switch is on; on a phone, also check silent mode.
Can I set a timer longer than an hour?
Yes — enter hours, minutes and seconds under “your time”, up to 23:59:59.
Can I show the timer on a big screen?
Yes. Press the full-screen button and the countdown fills the screen — handy for a projector or a TV.
