Frequently Asked Questions

What is the difference between split and total columns?

Split is the time for that lap alone; total is elapsed time from the very start to that lap.

How many laps can I record?

The list grows as needed; long interval sessions with dozens of laps stay smooth.

Which key records a lap?

Press L, or tap the Lap button, while the stopwatch is running.

Does lapping pause the clock?

No. Lap marks the moment and timing continues uninterrupted.

Can I see my fastest lap?

Yes. The list highlights fastest and slowest splits for quick review.

What happens to laps when I pause?

They remain in the list; pausing never deletes recorded splits.

Can I export the lap list?

Copy it before reset, or use the export stopwatch variant for file downloads.

Why do my splits vary so much?

Inconsistent lap trigger points are the usual cause; fix one physical marker and remeasure.
