Tips & Best Practices
- Use the same start cue every session so day-to-day comparisons stay fair.
- Note context such as rest length or temperature next to saved lap values.
- Keep the tab in view; switching away invites accidental resets.
Common Mistakes to Avoid

- Clearing the display before writing down totals you meant to keep.
Frequently Asked Questions
What is the difference between a stopwatch and a timer?
A stopwatch counts up from zero to measure elapsed time; a timer counts down from a preset value to zero.
Can I pause and resume?
Yes. Stop pauses the clock and Start resumes it without clearing recorded laps.
How many laps can I record?
The lap list grows as needed; practical sessions with dozens of laps remain smooth.
Does the stopwatch keep running in a background tab?
Yes, elapsed time stays correct, though some browsers slow display updates until you return.
Is it free to use?
Yes. The stopwatch is free with no account or download required.
Can I use it on a phone?
Yes. The controls are touch-sized and the digits scale to small screens.
What happens if I close the tab?
The session ends, so copy any laps you need before closing or resetting.
How precise are the readings?
Readings update to hundredths of a second, which is enough for training and everyday measurement.
