Keys: Space starts or pauses, R resets, and L records a lap on the stopwatch.
The page opens with 5 minutes in the fields, so the display reads 05:00. When you press Start or Space, the countdown begins. The page title shows the time left, so you can check it from another tab without going back to the timer.
Five minutes works as a short break, or as a fixed limit on a quick tidy: start the timer and stop when the tone sounds. If the job needs more time, the 10 minute timer gives you a longer block.
How to set a countdown timer
- Pick a preset, or type hours, minutes and seconds, then press Start.
- Switch to Stopwatch for laps, and press Lap or L to record each one.
- Switch tabs if you like. The time stays right, and a tone sounds when a timer reaches zero.
Questions
What if I want a 5 minute break every hour?
The timer runs one countdown at a time and does not repeat by itself. Start it again for each break, and keep the volume up so you hear the tone.
How do I stop the timer before the tone?
Press Space to pause it, and press R to reset it. A paused timer keeps the time left, so the tone still comes at the right moment when you carry on.
Why does the timer stay accurate when I switch tabs?
It reads the clock rather than counting ticks. When it starts, it saves the end time, and each update subtracts the current time from that. Browsers slow down timers in background tabs, so a counter that adds one per tick can drift. This one does not.
Will the sound play if the tab is in the background?
The tone is made in the browser and scheduled on the audio clock when the timer starts, so it sounds at the end time even if the tab is in the background. The page title shows the time left while it runs. Your device volume and mute settings still apply, and on phones the browser may stop sound when the screen locks, so keep the page open and the volume up.
Does the screen stay on while the timer runs?
Only if you tick the box, and only where the browser supports the Screen Wake Lock. The browser releases the lock when the tab is hidden, so the page asks again when you come back.
What do the lap times mean?
Each lap time is the time since the previous lap, and the total is the time since the stopwatch started. Reset clears the laps. Nothing is saved after you close the page.
