Background
About stopwatch
A stopwatch answers a different question than a countdown: not "is time up?" but "how long did that take?" Measuring elapsed time is the foundation of improvement in almost any repeatable activity — workouts, drills, cooking steps, task estimates, and practice sessions.
Timing your work also fixes estimation. Most people misjudge how long routine tasks take by a wide margin; a week of casual measurement replaces guesses with data, which makes planning dramatically more realistic.
These guides cover practical stopwatch use — lap timing, task measurement, estimate calibration — with a free browser stopwatch that starts in one click.

FAQ
Common questions about stopwatch
What is a stopwatch useful for besides sports?
Calibrating estimates. Timing routine tasks for a week replaces guesses with data — most people discover their "quick" tasks take two to three times longer than assumed, which transforms planning.
Stopwatch or countdown — which should I use?
Countdown when you want a boundary ("20 minutes on email"), stopwatch when you want a measurement ("how long does this report actually take?"). They answer different questions.
