Question 1

What is a stopwatch?

Accepted Answer

A timer that measures elapsed time with start, stop, and reset controls. Our stopwatch displays hours, minutes, seconds, and milliseconds. Use for workouts, cooking, productivity (Pomodoro), timing experiments, and event timing.

Question 2

How accurate is the browser stopwatch?

Accepted Answer

Browser timers are accurate to ~4ms but can drift during heavy CPU load. For casual timing (cooking, workouts, productivity), it's excellent. For scientific timing (race results, lab experiments), use a dedicated stopwatch.

Question 3

What is lap time?

Accepted Answer

Lap/split time records the time of each segment without stopping the main timer. Track lap 1 (0:15.2), lap 2 (0:14.8), lap 3 (0:16.1), etc. Our stopwatch supports lap recording for interval training and event timing.

Question 4

Stopwatch vs countdown timer?

Accepted Answer

Stopwatch: counts up from zero. Timer: counts down from a set time. Stopwatch measures elapsed time. Timer alerts when time is up. Both are useful — use stopwatch for 'how long', timer for 'when to stop'.

Question 5

What is the Pomodoro Technique?

Accepted Answer

25 minutes work, 5 minutes break. Repeat 4×, then 15-30 min break. Use a stopwatch for the work timer and break timer. Popular productivity method by Francesco Cirillo. Our stopwatch tracks your Pomodoro sessions.

Question 6

Can I use stopwatch for workouts?

Accepted Answer

Yes — track rest between sets (60-90 sec for hypertrophy, 3-5 min for strength), measure circuit duration, record cardio intervals (30 sec sprint, 90 sec recovery), and log total workout time. Lap feature tracks each exercise.

Question 7

What's the maximum time on a stopwatch?

Accepted Answer

Our stopwatch: 99 hours, 59 minutes, 59 seconds (about 4 days). Browser-based stopwatches can technically run for days. For longer durations, use a calendar or dedicated timer app.

Question 8

Does the stopwatch keep running if I close the tab?

Accepted Answer

No — browser timers stop when the tab is closed or the device sleeps. The timer uses JavaScript's setInterval which requires the page to be active. For background timing, use a mobile stopwatch app or dedicated timer.

Question 9

Stopwatch vs interval timer?

Accepted Answer

Stopwatch: single elapsed time measurement. Interval timer: alternates between work/rest periods automatically. For HIIT workouts, use an interval timer app. For general timing, our stopwatch with lap feature works well.

Question 10

How to use stopwatch for productivity?

Accepted Answer

Track time spent on tasks: start when you begin, stop when you finish. Record each task's duration. Review at end of day — see where time actually goes. 'Time blocking': assign stopwatch to each block.
