About the Stopwatch
A general-purpose stopwatch is the baseline tool when you do not need a specialty layout yet still want trustworthy elapsed time. Reach for it when the task is ordinary but the stakes are real: how long did the sauce reduce, how long was the patient in triage, how long did the keynote run over. This stopwatch keeps the interface calm so the numbers stay authoritative. Athletes use it for informal repeats, tutors time mental-math sprints, and makers measure cure times for glue or resin.
How to use it
- Open the stopwatch and position the window within easy sight of the activity.
- Press Start or Space at the exact moment the activity begins.
- Add laps at each rep, station, or checkpoint to record splits.
- Pause with Stop if interrupted; earlier laps remain in the list.
- Reset only after saving any values you need for your records.
Good to know
The stopwatch counts while this tab is open. A slept tab can pause or jump. For a race result you may need to keep the phone unlocked in your hand.
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.
