Put a clock or timer on the big screen that everyone in the room can read. Choose a clock with the date, a countdown timer with an alarm, or a stopwatch with laps, then go full screen on a projector, TV, laptop or tablet. Dark, light, green and amber colour themes keep it easy on the eyes, and the screen is kept awake while it runs.
loading toolHow to use the full-screen clock and timer
- Choose Clock, Timer or Stopwatch.
- For a timer, type the time (5, 1:30 or 1:00:00) or tap a quick button.
- Press Start, and Full screen to fill the screen.
- The timer beeps and turns red at zero; Reset to run it again.
Good to know
- In the last 10 seconds the digits turn red, so a speaker can see time is nearly up.
- Green and amber themes are easy to read from the back of a hall and gentle in dark rooms.
Questions
Will the alarm ring if I switch tabs?
Yes, as long as the page stays open: the timer runs on the real clock, so it stays right even in the background. Some phones pause pages when the screen locks, so keep the screen on (the tool asks for this automatically).
How do I set 1 hour 30 minutes?
Type 1:30:00 in the timer box, or 90 (a plain number means minutes).
Can I control it with the keyboard?
Yes. Press the Space bar to start and pause the timer or stopwatch, and double-click the clock to go full screen.
