Frequently Asked Questions
Q: How accurate is this online stopwatch?
The stopwatch utilizes high-resolution browser performance timestamps (performance.now() and Date.now()) alongside requestAnimationFrame. This delivers sub-millisecond precision with zero drift, even when backgrounded or run across long multi-hour durations.
Q: How do lap splits and delta calculations work?
Whenever you click Split Lap (or press L), the stopwatch records both the individual lap duration (split time) and the cumulative overall elapsed time. It automatically highlights the Fastest Lap (⚡ Best) and Slowest Lap (⏳ Slowest), while calculating variance against the overall average lap pace.
Q: Can I export or copy my recorded lap times?
Yes. You can copy the entire lap table to your clipboard formatted as plain text or click Export CSV to download a spreadsheet-ready .csv file complete with lap numbers, split times, cumulative times, and variance metrics.
Q: What is the Speedcubing & WCA Inspection mode?
Designed for Rubiks Cube speedsolvers, this mode provides an official 15-second WCA inspection countdown with audio warnings at 8 and 12 seconds. Solvers can hold the Spacebar to arm the timer and release to start timing their solve with zero touch latency.
Q: What keyboard shortcuts are supported?
You can control the stopwatch using standard keyboard hotkeys: Space or Enter to Start/Pause, L to record a Lap Split, R to Reset, F to toggle Fullscreen Stage Mode, and M to Mute or Unmute audio sound effects.
