Frequently Asked Questions
Can I set custom time?
Yes, you can set hours, minutes, and seconds.
Does it work in background?
Yes, and you'll get a notification when time is up.
Can I save my frequent durations?
Yes. Save the current time as a preset and start the same countdown with one tap next time.
What does auto-restart do?
When time runs out, the timer starts again by itself — ideal for interval workouts and repeated kitchen tasks.
Is it free, and is there a fullscreen mode?
Completely free — and one tap switches to a big-digit fullscreen view. It runs in your browser, nothing to install.
Will the alarm sound if I'm in another tab?
The countdown keeps running in the background and the alarm plays when time is up — just keep the browser tab open.
