Quick times

Sound is off until you turn it on. Then a chime plays at zero if your browser allows it.

What a 20 Minute Timer Is Good For

  • Reading block

    Twenty minutes with a book at home or in class, with the clock doing the checking.

  • Writing time

    Enough for a first draft of a short piece, started from a writing prompt.

  • Small groups

    You sit with one small group while the others work, and change groups at zero.

How to Use It

  1. The clock opens at 20 minutes, and nothing runs until you press Start. To change it, press a quick button or type a new time.
  2. Press Start, or press Space if you’re not typing in a field.
  3. Press Pause if you need to stop for a moment, then Resume. Need longer? Press +1 minute.
  4. Press Big screen to show only the clock on a projector.
  5. Turn Sound on if you want a chime at zero. Either way, the clock says Time’s up!
  6. Press Reset to go back to the time you set.

Frequently Asked Questions

Can I use a 20 minute timer for reading at home?

Yes. Open it on any phone, tablet or laptop and press Start. Put the device where you can see the ring. There’s nothing to sign in to.

Will the screen stay on for 20 minutes?

Where the browser allows it, yes: the page asks the device to keep the screen awake while the timer runs and lets go when it stops or is paused. If your browser can’t, change your device’s screen setting for the lesson.

Will it make a sound at zero?

Only if you turn Sound on with the switch by the clock. It’s off until you do, and the same switch works for every wheel on this device. Then a chime plays at zero if your browser allows it. A browser can block sound, so keep the clock in view.

Does it keep time if I switch tabs?

Yes. It works from the time it should end, not by counting ticks, so the clock is right when you come back. The time shows in the tab’s title while it runs.

Can I show it on a projector?

Yes. Press Big screen and only the clock fills the screen, large enough to read from the back of the room. Press Space to pause or start it there, and Escape or Leave big screen to go back.

Is anything saved?

No. The timer runs in your browser and nothing about it is sent to us. Reload the page and it starts fresh. Your Sound choice stays on this device only.

Is it free?

Yes. There’s no sign-up and nothing to install.
