FAQ
Will the alarm ring if I switch tabs?
Yes. The alarm is scheduled when you press Start, so it rings on time even in a background tab, and the tab title shows the time left. It may not sound if your computer goes to sleep.
I can't hear the alarm.
Check the volume slider and your system volume, then press Test sound. Phones in silent mode may block sound.
What is the Pomodoro technique?
Work for 25 minutes, take a 5-minute break, and take a longer break every 4 rounds. You can change all the durations.
