About
About the Countdown Timer and Stopwatch
Combines a countdown timer that alerts you when time's up with a stopwatch that counts up and records lap times.
People running a focused work session or a cooking timer use the countdown half, while athletes and anyone timing an activity with distinct segments use the stopwatch's lap tracking. It's one of many free calculators on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

FAQ
Frequently asked questions
Quick answers to common questions about the Countdown Timer and Stopwatch.
What does the Countdown Timer and Stopwatch do?
It's two tools in one: a countdown timer that runs down from a set time and alerts you when it's done, and a stopwatch that counts up and records lap times.
Is the Countdown Timer and Stopwatch free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Do I need to click a button to start the countdown or stopwatch?
Yes. Each has its own Start button — the countdown and stopwatch run independently of each other and don't start automatically.
What happens when the countdown reaches zero?
It stops automatically and shows a "Time's up." message. Click Reset to set it back to your chosen minutes and seconds.
Can I pause the countdown and resume it later?
Yes. Click Pause to stop it without losing the remaining time, then Start again to continue from where it left off.
Does the timer keep running if I close the browser tab?
No. Like any browser-based timer, it only runs while the page stays open — closing or reloading the tab stops it.
How precise is the stopwatch?
It displays time to a tenth of a second, which is precise enough for most everyday timing needs.
Can I use the Countdown Timer and Stopwatch on my phone?
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
