An online stopwatch or timer is one of those tools you reach for when you do not want to unlock your phone or dig for a dedicated app. It lives in a browser tab, starts with one click, and gets out of the way. This one handles two modes: a stopwatch that counts up from zero, and a countdown timer where you set the duration and it counts down.
Uses vary: timing a presentation run-through, a cooking step, a workout interval, a focused work session, or a meeting that should not run long. The countdown timer can alert you when time is up so you do not have to watch it constantly.
Frequently Asked Questions
Does the timer continue if I switch browser tabs?
Modern browsers throttle background timers for performance reasons. For accurate timing in another tab, keep this tab visible or use a dedicated timer app. For casual use, background throttling is usually minor.
Can I use this as a Pomodoro timer?
Set the countdown to 25 minutes, work until it goes off, then reset for a 5-minute break. It works fine as a manual Pomodoro setup, though it does not automate the work/break cycles the way dedicated Pomodoro apps do.
Will the alarm work with sound muted?
No - browser sound alerts require audio to be enabled. If your device is muted, you will only see the visual indication when the timer ends.
