Frequently asked questions
Will the timer keep running if I switch tabs?
Yes. The timer compares against your device clock, so it remains accurate when you return to the tab.
Can I run more than one timer?
Yes. Create multiple countdowns or stopwatches and control each one separately.
How do shared timer links work?
A shared link stores the timer label, mode, duration, and timezone in the URL. It does not upload your timer data.
Why might the alarm be silent?
Your browser or device may block sound until you interact with the page or may be muted.
