Our free online stopwatch provides precise time measurement for any activity. Whether you're timing workouts, tracking cooking times, measuring study sessions, or recording race splits, this digital stopwatch delivers accuracy down to milliseconds. The clean, easy-to-read display works perfectly on any device.

With lap time functionality, you can track multiple intervals without stopping the main timer. Perfect for athletes tracking workout splits, teachers timing student activities, or anyone needing to measure multiple events within a single timing session. All lap times are saved and displayed for easy reference.

Unlike physical stopwatches that require batteries and can be lost or forgotten, an online stopwatch is always accessible from any device with internet. Your browser provides the timing mechanism, ensuring accuracy comparable to dedicated hardware without the hassle of carrying extra equipment.

The lap time feature transforms a simple timer into a powerful tracking tool. Athletes can analyze their performance across multiple intervals, fitness enthusiasts can record circuit training rounds, and students can track study session segments. All data is displayed clearly, making it easy to review and compare times.

For best results, keep the stopwatch tab active or in the foreground during timing. While modern browsers continue background timing, having the tab visible ensures you can quickly record lap times when needed.

When recording lap times for athletic events, practice hitting the lap button before you actually need it. The slight delay in human reaction time means you should anticipate when to press, especially for fast-moving events like sprinting or swimming.

For cooking or tasks requiring exact timing, set a backup alarm or timer for critical moments. While our stopwatch is precise, having a reminder ensures you don't miss important timing checkpoints while focusing on other tasks.

Use a stopwatch when you need to measure how long something takes – tracking duration from start to finish. Examples include workout sessions, race times, cooking preparation, or study periods. Stopwatches count up from zero, perfect for tracking elapsed time.

Use a countdown timer when you need to be alerted after a specific duration – setting a fixed time limit. Examples include baking times, meditation sessions, pomodoro work intervals, or exam time limits. Timers count down to zero and alert you when time is up.
