FAQ

FAQ

Will the timer keep running in a background tab?

Yes. The timer counts from the actual end time, so it stays accurate even if you switch tabs or the browser slows the page down. Keep the tab open so you can hear the alert.

I can't hear the alert sound.

Press “Test sound” at the top once to let the browser play audio. On iPhone, turn off silent mode and check your volume.

What is the Pomodoro technique?

It's a way to work in short focused bursts: typically 25 minutes of focus followed by a 5-minute break. You can change both lengths, and today's completed sessions are saved in this browser.
