Frequently Asked Questions
How accurate is online stopwatch?
Our online stopwatch uses the browser's high-resolution timer with millisecond accuracy, suitable for most timing needs including workouts, experiments, and productivity tracking.
What is lap time?
Lap time records the duration of each completed lap/segment. Split time shows the cumulative time from the start. Both are useful for fitness and performance tracking.
Can I use stopwatch in background?
The stopwatch continues running even if you switch tabs, but browser timer throttling may reduce accuracy after several minutes in background tabs.
