What a 20 minute timer is good for
Workshop activities
Twenty minutes gives small groups time to try something and report back. Large digits on the projector keep every table on schedule.
Naps
A twenty-minute nap is a popular length for a short rest in the afternoon. Turn the volume up before you lie down.
Focused homework
Work for twenty minutes with the phone away, then take a short break. Children often find a visible end time makes starting easier.
Questions
Why just digits on this page?
Over twenty minutes the exact time left matters more than a shape, and digits fill the screen best in full screen. Choose a pie or bar under the timer if you'd like one; this page remembers your choice.
Can I see the time left while I work in another tab?
Yes. While the timer runs, the tab title shows the time left, like "12:30". It changes to "Time's up!" at zero.
How do I run a workshop activity that overruns?
Tick "Count up after zero". After the alarm, the digits count up with a plus sign, so you can see how long you're running over.
How do I split homework into twenty-minute blocks?
Work until the alarm, take a short break, then press Restart for the next twenty minutes. Press Pause if you need to stop in the middle, and Resume to carry on.
