Frequently Asked Questions
What is the difference between a timer and a stopwatch?
A timer counts down from a set time to zero and alerts you. A stopwatch counts up from zero to measure elapsed time. Use a timer when you need to finish within a fixed period; use a stopwatch when you want to record how long something takes.
Is the timer accurate when I switch tabs?
Yes. The timer calculates elapsed time using Date.now(), so it stays accurate even when the tab is in the background.
Why is there no alarm sound?
Browsers block audio until the user interacts with the page. Click Start directly to allow sound, and the alarm will play normally when the countdown ends.
What is the Pomodoro Technique?
It is a time management method using 25-minute focused work sessions followed by 5-minute breaks. Use the 25-minute preset to get started quickly.
