Frequently Asked Questions
Will the timer ring if I minimize the browser?
Yes, the timer will keep counting down if you minimize the browser window or switch to other tabs. However, since modern browsers may throttle background processes to save power, we recommend keeping the window active or testing it quickly beforehand.
Can I use this timer for study or work sessions?
Absolutely. This tool works perfectly as a free focus timer for studying or a browser timer for work. You can set study blocks (like 25-minute Pomodoro sessions) and hear an audio alert once the countdown is finished.
Does the timer keep running if my computer sleeps?
No. Web browsers pause layout and timing tasks when your computer goes into sleep, standby, or hibernation modes. Your device must remain awake and active with the browser open for the countdown to complete and sound correctly.
Can I use it for cooking or workouts?
Yes! It can be used as a simple online cooking timer on your desktop or an online workout timer with intervals. Just set the required time on your laptop or PC and let it trigger the audio notification upon completion.
Why should I keep the tab open?
The timing loop and active session are maintained purely in your open browser tab. If you close the page or shut down your browser, your countdown session will be deleted and the timer will stop immediately.
