Frequently Asked Questions
How to set a countdown timer online?
Pick a preset such as 5 Min or 25 Min Pomodoro, or enter custom hours, minutes and seconds, then press Start. The timer counts down and plays an alarm sound at zero.
Does the timer work if I switch tabs?
Yes. EZCountdown calculates the remaining time from the system clock, so it stays accurate in background tabs, and the remaining time is shown in the browser tab title.
Can I use this for Pomodoro study sessions?
Yes. Use the 25 Min Pomodoro preset for focus sessions, then the 5 Min preset for breaks. Turn on Loop to repeat intervals automatically.
Will the alarm sound play automatically?
Yes. Press Start once so the browser allows audio, keep the tab open and your volume up, and the alarm plays when time is up. You can test and change the sound at any time.
Is EZCountdown free and private?
Yes. It is 100% free, needs no sign-up and runs entirely in your browser. No data is sent to any server.
