30 Second Timer
What a 30 second timer is good for
People use this timer for a plank or wall sit, a jump rope burst and one turn in a party game. Thirty seconds is the usual hold for beginner planks and stretches; repeat it three times with a short rest.
How it works
Under the digits you see the clock time when the timer ends. Need a little longer? Tap +1 min while it runs. Switch between numbers, a progress ring, a visual disc and a sand timer.
Space starts and pauses, R resets and F opens fullscreen. The screen stays on, and the timer follows the real clock, so it stays accurate when the tab is in the background.
Questions
How do I set a 30 second timer?
Press Start on this page: the timer is already set to 30 seconds. To change it, tap the digits or pick another preset.
Is there a 30 second timer with sound?
Yes. Pick one of several alarm sounds and a volume, and turn on repeat until stopped so you do not miss it.
Will it ring in a background tab?
Yes. The countdown follows the system clock and the alarm rings even if you switch tabs. Keep the tab open.
Can I repeat it for intervals?
For repeated work and rest, the interval timer runs the rounds for you with voice cues.
