15 Minute Timer
What a 15 minute timer is good for
People use this timer for a classroom activity, a power nap and letting a roast rest. A 15-minute nap refreshes without grogginess, because you wake up before deep sleep.
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.
