Using the 25 minutes timer
The timer is already set to 25 minutes. Start it with the button, the space bar or a tap on the display; pause with the same. +1 min extends it while it runs, and Reset puts it back to 25 minutes. Turn on Restart automatically to repeat every 25 minutes, or change the hours, minutes and seconds for a different length.
The time left shows in the browser tab, so you can switch to another tab and still see it. Leave the tab open and your device awake for the alarm to sound.

Questions
How do I set a 25 minutes timer?
This page is already set to 25 minutes. Press Start or the space bar and the alarm sounds when it reaches zero.
Can I repeat the 25 minutes timer?
Turn on Restart automatically and the timer begins another 25 minutes as soon as the alarm sounds.
Will it keep counting if I switch tabs?
Yes. The countdown is based on the end time, so switching tabs or reloading doesn't change it. Keep the tab open for the alarm.
