Free Stopwatch & Countdown Timer
Precise stopwatch with lap times and customizable countdown timer with quick presets.
This free online stopwatch and timer works right in your browser. Use the stopwatch for timing activities with lap support, or set a countdown timer for focused work sessions, cooking, workouts, and more.
Quick timer presets let you start common durations with one click. Set custom timers for any length. An audio alert notifies you when the countdown reaches zero. No signup or installation required.
Choose elapsed time or a countdown
Use the stopwatch when you want to measure how long an activity takes. Start it when the activity begins, pause when needed and record laps to compare parts of a session. Use the countdown mode when you already know the time available, such as a short presentation or a focused work period. Set the duration before starting and check that the selected mode matches your purpose.
Use timing to review your routine
For repeated activities, compare similar sessions rather than treating one result as a permanent estimate. A long meeting may include useful discussion, while a short task may still need a quality check. Record the context alongside any important time measurement. The timer can support a personal routine, but it does not automatically explain why an activity took longer or shorter than expected.
Keep the browser environment in mind
A browser timer depends on the page and device remaining available. Closing the page, sleeping the device or restricting background activity can interrupt its behaviour, and sound depends on browser settings. Check the timer before relying on an alert and use a dedicated alarm for critical reminders. Reset only after you have recorded any lap information you need. Choose a duration that leaves enough time to finish and review the activity.
