Countdown

Press Space to startTap the time to start

Pick a preset (1–60 minutes) or type hours, minutes and seconds, then press Start or Space. Use the fullscreen button for a projector or TV — on iPhone it fills the screen.
While it runs, any key pauses the countdown, and any key resumes it. Turn off Pause with any key if you use a presentation clicker, and only Space will. On a phone, tap the time.
A soft beep marks every second. Near the end the clock turns red and pulses, beeping on every pulse, faster and faster as it nears zero. At zero, TIME'S UP! stamps over the clock and an alarm rings. Turn on Count up after zero to show how far over time a talk has run.
Timing uses the browser's high-resolution clock, so it stays accurate even if the tab is in the background, and the screen is kept awake while it counts.
