Question 1

How accurate is this online stopwatch?

Accepted Answer

The stopwatch uses your browser's high-resolution timer API for millisecond-level accuracy. It is precise enough for most practical purposes including sports training, cooking, and experiments. For scientific research requiring extreme precision, dedicated hardware may be preferable.

Question 2

Can I record multiple lap times?

Accepted Answer

Yes! You can record unlimited laps. Each lap shows the lap number, the split time (time since the last lap), and the cumulative total time. The lap table appears automatically when you record your first lap.

Question 3

What happens to my laps if I pause the timer?

Accepted Answer

Your laps are preserved when you pause. The timer simply stops counting until you resume. All previously recorded laps remain visible in the lap table, and you can continue recording new laps after resuming.

Question 4

Does the stopwatch work if I switch to another tab?

Accepted Answer

Yes, the stopwatch continues running even if you switch to another browser tab or minimize the window. However, for best accuracy, keep the tab active as some browsers may throttle background tabs.

Question 5

Can I use keyboard shortcuts instead of clicking buttons?

Accepted Answer

Yes! Press Space to start, pause, or resume the timer. Press R to reset. Press L to record a lap (only works while the timer is running). These shortcuts make the stopwatch easier to use during activities like workouts.

Question 6

Is my timing data stored anywhere?

Accepted Answer

No. All timing data is processed entirely in your browser. No lap times, elapsed times, or any other data are transmitted to or stored on any server. Your privacy is fully protected.

Question 7

Can I export or share my lap times?

Accepted Answer

Currently, you can manually copy lap times from the display. For now, the tool focuses on real-time timing. Future updates may include export functionality for lap data.

Question 8

Does the stopwatch work offline?

Accepted Answer

Once the page is loaded, the stopwatch will continue to work even if you lose your internet connection, since all processing happens client-side. However, you need an internet connection to initially load the page.
