About Timer & Stopwatch
The Automarkly Timer & Stopwatch is a free, accurate and beautifully simple time-tracking tool that combines two essential utilities in one clean interface. Whether you are timing a workout, running a Pomodoro session, managing exam minutes, cooking, or tracking how long a task takes, this tool gives you millisecond-precise timing without installing any app. Everything runs locally in your browser using the high-resolution Performance API, so there is no drift and no reliance on a remote server.
The stopwatch mode counts up from zero and displays hours, minutes, seconds and centiseconds. It is perfect for measuring elapsed time for races, presentations, coding sprints, or any activity where you need to know exactly how long something took. The timer mode counts down from a duration you set in minutes and seconds, then plays an audible alert when it reaches zero — ideal for focused work intervals, break reminders, or kitchen timing.
Unlike phone apps that clutter the screen with ads and upsells, Automarkly keeps the interface minimal and distraction-free. The large monospaced readout is easy to glance at from across the room, and the start, pause and reset buttons are large enough to tap comfortably on any device. The tool is fully keyboard accessible and works in both light and dark mode.
Because all timing happens client-side, the tool keeps working even if your internet connection drops mid-session. There are no accounts, no tracking, and no data stored anywhere. Bookmark this page and you will always have a reliable stopwatch and countdown timer one click away, on any device.

Frequently Asked Questions
How accurate is the Automarkly stopwatch?
It uses the high-resolution performance.now() timer, which is far more accurate than setInterval and avoids drift. Times are displayed to the centisecond (1/100 of a second).
Will the timer keep running if I switch tabs?
Yes. Timing is based on elapsed real time, not on the tab being active, so it continues accurately even when the tab is in the background.
Does the countdown timer make a sound?
Yes. When the countdown reaches zero, a short beep plays using the Web Audio API. Make sure your device is not muted to hear it.
Is this tool free and ad-free?
Yes. The timer and stopwatch are completely free. Like all Automarkly tools, there are no sign-ups and no data collection.
Can I use this on my phone?
Absolutely. The interface is fully responsive and touch-friendly, so it works just as well on a smartphone as on a desktop.
