3 Hour Timer
What a 3 hour timer is good for
People use this timer for a long exam, a slow-cooked stew and a parking limit. For long timers, keep the device plugged in and the tab open; the end time is shown under the digits.
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.
