Frequently Asked Questions
What is the difference between a count up timer and a stopwatch?
A count up timer displays elapsed time in hours, minutes, and seconds without hundredths precision or lap tracking. It is simpler and suited for tracking longer durations like meeting length or parking time. A stopwatch offers sub-second precision and lap recording.
Does the count up timer continue in the background?
Yes. The timer uses Date.now() to calculate elapsed time, so it remains accurate even if the browser tab is in the background. The display updates when you return to the tab.
Can I pause and resume the count up timer?
Yes. Click Pause to freeze the display, then click Resume to continue from where you left off. Click Stop to freeze the final time, or Reset to clear it back to zero.
