Track time with millisecond precision using vTickr's free online stopwatch. Perfect for sports, running, workouts, experiments, and any activity that requires accurate time measurement with lap tracking.
Start Stopwatch →An online stopwatch is a digital timing tool that counts up from zero, measuring elapsed time with high precision. Unlike a countdown timer that counts down to zero, a stopwatch measures how much time has passed since you started it.
vTickr's free online stopwatch features millisecond accuracy, making it ideal for precise timing in sports, fitness, scientific experiments, and everyday activities. The built-in lap function allows you to record split times without stopping the main timer.
Track your run times, record lap splits, and monitor your progress over time.
Time your laps in the pool and track improvements in your swim times.
Track total workout duration, rest periods, and exercise intervals.
Precise timing for laboratory experiments and scientific observations.
Time game rounds, speed challenges, and competitive activities.
Measure how long tasks actually take for better time estimation.
The lap function allows you to record intermediate times without stopping the main stopwatch. This is essential for tracking split times in running, swimming, or any multi-segment activity.
Press the Spacebar to quickly start or pause the stopwatch without clicking. Use Alt+4 to jump directly to the Stopwatch tab from anywhere on vTickr.
The vTickr stopwatch displays time in the format: HH:MM:SS.mmm
For example, 01:23:45.678 means 1 hour, 23 minutes, 45 seconds, and 678 milliseconds.
A millisecond is one-thousandth of a second (0.001 seconds). There are 1,000 milliseconds in one second. This level of precision is important for:
Use lap times to track each mile or kilometer of your run. Compare your splits to identify where you're slowing down or speeding up. Aim for consistent lap times for better pacing.
Record lap times for each length of the pool. Track your turns and push-offs to identify areas for improvement. Compare times across different strokes.
While a timer is typically better for structured intervals, a stopwatch is great for tracking total workout time and recording how long each circuit takes.
Time sprints, drills, and activities during practice. Use lap times to record multiple athletes' performances in sequence.
Keep a training log of your stopwatch times. Recording your lap times regularly allows you to track improvement over weeks and months. Even small improvements in times can indicate significant fitness gains.
vTickr's stopwatch uses JavaScript timing functions with millisecond precision. While it's extremely accurate for most purposes, factors like browser performance can introduce minimal variations (typically less than 10ms).
Yes! The stopwatch continues running accurately even when you switch to other tabs or applications. The time is calculated based on actual elapsed time, not just counting intervals.
Absolutely. vTickr is fully mobile-responsive and works on smartphones and tablets. Simply open vtickr.com in your mobile browser.
The stopwatch can run for over 99 hours, which is more than sufficient for any practical timing need.
Lap times are displayed during your session but are cleared when you reset or leave the page. For permanent records, we recommend noting your times manually or taking a screenshot.
A stopwatch counts UP from zero, measuring how much time has passed. A timer counts DOWN from a set time to zero. Use a stopwatch when you want to measure duration; use a timer when you need to track remaining time.
Whether you're training for a race, timing experiments, or just curious how long something takes, vTickr's free stopwatch is ready to help.
