This timer counts down 15 minutes (900 seconds) and plays an alarm at zero. It is handy for a power nap, a short workout, a time-boxed chore or a quick meeting stand-up. It runs entirely in your browser: nothing is uploaded.
Press Start on this page. The 15 minute timer is already set to 15:00 and sounds an alarm when it reaches zero. Press Pause to stop it and Reset to start over.
Common uses are a power nap, a short workout, a time-boxed chore or a quick meeting stand-up.
Usually yes. The timer follows the clock, so it stays accurate in a background tab, and the remaining time shows in the tab title. Keep the page open until it finishes, because it cannot ring after you close it. Some browsers block sound until you have clicked on the page, which pressing Start counts as.
15 minutes are 900 seconds.
