Count down. Or count up. Your call.
Set hours, minutes and seconds, add a label, and let it run. The ring shows progress, the sound tells you when it's done — all in your browser.
Max 99 hours, 59 minutes, 59 seconds. For count-up mode the starting time is ignored.
Shown under the digits so you remember what the timer is for.
Four steps, a running timer.
No manual required — here's the entire flow.
Pick a mode
Choose Count Down for a classic timer, or Count Up if you want a stopwatch that runs from zero.
Set the time
Enter hours, minutes and seconds — or tap a quick preset like 5 or 25 minutes. Add a label if you like.
Press Start
The ring sweeps down (or up), the digits count, and the tab title shows the remaining time. Pause and resume anytime.
Hear the alert
When the countdown hits zero, a sound plays and the status turns amber. Reset to run it again.
Built for focus, not fiddling.
The details that make a timer feel invisible while it works.
Runs on your device
All timing runs locally in your browser with JavaScript. Your labels and durations never leave your device.
Visual progress ring
A clean ring shows how much time is left or elapsed, so you can glance without reading numbers.
Sound alert at zero
When the countdown finishes, a short tone plays so you never miss the moment. Turn it off if you prefer silence.
Questions people actually ask.
The short answers — with the long ones one tap away.
How do I use this countdown timer?+
Set the hours, minutes and seconds you need, optionally add a label, then press Start. The ring counts down visually and a sound plays when the time reaches zero. You can pause, resume or reset at any point.
Does the countdown timer make a sound when it finishes?+
Yes. When the countdown reaches zero, a short alert tone plays through your device speakers. Make sure your volume is up and the browser tab is not muted. You can toggle the sound off with the speaker button.
Can I use this as a stopwatch or count-up timer?+
Yes. Switch to Count-up mode and the timer counts upwards from zero instead of counting down, behaving like a stopwatch. Pause, resume and reset work the same way.
Is my timer data uploaded anywhere?+
No. The countdown timer runs entirely in your browser using JavaScript. Your times, labels and settings never leave your device.
What is the maximum countdown length?+
You can set up to 99 hours, 59 minutes and 59 seconds, which is enough for almost any study, cooking or productivity session.
Will the timer keep running if I switch tabs?+
Yes. The timer uses the system clock, so it keeps accurate time even if you switch tabs or minimise the window. The tab title updates so you can glance at the remaining time.
Can I use this countdown timer for Pomodoro sessions?+
Absolutely. Use the 25 minute preset for a classic Pomodoro work interval, or set your own custom work and break lengths. The sound alert tells you when to switch.
Is this countdown timer free?+
Yes, it is completely free with no account, no sign-up and no usage limits.
