The timer runs in this tab, needs no account and keeps time even if the tab is in the background.
Using it in class
Type what the time is for, such as Group work or Tidy up, choose a preset or set your own minutes and seconds, then press Start and Full screen. On a projector or a big screen the numbers fill the display. In the last minute they turn orange, in the last ten seconds red, and the screen flashes gently when time is up.
Keyboard controls
Space starts and pauses, R resets, F switches full screen on and off, and the up and down arrows add or take away a minute while it runs. Press a number from 1 to 9 to set that many minutes straight away, which is handy with a presenter remote or a wireless keyboard.
Counting up
Count up works like a stopwatch, for timing a presentation or a reading. The chime can be switched off for quiet rooms, and your last time and label are remembered for next time on this device.
