Frequently Asked Questions

What is the difference between a stopwatch and a timer?

A stopwatch counts up from zero, measuring elapsed time for specific activities. A timer counts down from a set time and alerts you when it reaches zero.

What is a lap time?

Lap time records interval times while the stopwatch is running. For example, you can record the time to complete each lap while running. Each time you press the lap button, both the interval time and total elapsed time are recorded.

How accurate is the stopwatch?

This stopwatch measures in 10-millisecond (0.01 second) intervals. Since it is browser-based, slight inaccuracies may occur under heavy system load or when the tab is inactive. For professional precision measurements, dedicated equipment is recommended.

How can I best use the stopwatch and timer?

The stopwatch is useful for measuring rest time between exercise sets, presentation practice, and cooking time. The timer is great for the Pomodoro technique (25-minute focus), boiling noodles, and setting meditation durations. The multi-timer lets you manage multiple tasks simultaneously.
