❓ Frequently Asked Questions
Is this online timer free to use?
Yes, completely free. No registration, no downloads, no installation required. All timing logic runs locally in your browser — no data is ever uploaded to any server.
Will I be notified when the countdown ends?
Yes. When the countdown reaches zero, the timer plays an alert sound and requests browser desktop notifications (requires notification permission). You'll be notified even if you've switched to another tab.
What's the difference between countdown and stopwatch?
Countdown counts down from a set time to zero — perfect for Pomodoro, cooking, or exams. Stopwatch counts up from zero — ideal for workouts, speeches, or task timing. You can switch between modes anytime.
Does the timer work when the browser tab is in the background?
Yes. The timer uses real timestamp differences for calculation, so it stays accurate even when the browser tab is in the background. No timing drift from tab switching.
What is the maximum countdown duration?
The maximum is 99 hours 59 minutes 59 seconds, which is more than enough for most daily scenarios like studying, cooking, meetings, and workouts.
