Second Timers: Pick a Time and Press Start

Short countdowns for when every second counts: plank holds, interval rounds, quiz answers and quick games. Each one is ready to start, and you can press Reset to go again right away.

Every timer shows the time left in your browser tab and plays a chime at zero. It goes by your device's clock, so it stays on time even if you switch tabs.

A chime you will hear

A clear chime plays the moment the countdown hits zero, with nothing extra to load.

Phone, desktop or fullscreen

Fits your phone screen, and goes fullscreen for TVs, classroom boards and monitors.

Frequently Asked Questions

How do I start a timer?

Tap any timer in the list, for example the 5 minute timer, 10 minute timer or the stopwatch, then press Start. You can also type in the search box to find a time quickly.

Do the timers keep working in a background tab?

Yes. They go by your device's clock, so switching tabs doesn't slow them down. The time left also shows in the tab title. Just don't close the tab.

Will I hear an alarm when time is up?

Yes. A short chime plays as soon as the countdown reaches 00:00. Make sure your device isn't muted.

Are the timers free on phone and desktop?
