Questions
Which face should I use?
Digits are best for older students and exact times. The disc suits younger children, because it turns from green to amber to red. The hourglass is calm, for quiet work. The bomb and the rocket make games and tidy-ups exciting.
Will it show on a projector or interactive whiteboard?
Yes. Press Full screen and the timer fills the screen. The controls fade after 3 seconds without mouse movement, and the screen stays on while the timer runs, in browsers that support it.
Do I need an account or an app?
No. Open the page and press Start. There are no ads in the timer or in full screen, and nothing to install.
What happens at zero?
Digits and the disc ring an alarm and pulse once a second. The hourglass rings a soft bell. The bomb goes boom and the rocket lifts off. Turn off Sound for a silent finish.
What keyboard shortcuts are there?
Space starts and pauses, R resets, F goes full screen, M turns sound on or off, and + and − add or take off a minute.
Is anything sent to a server?
No. The timer runs in your browser. Your face and sound choices are remembered on this device only.
