🔬Technical Introduction
Core ConceptA chronometer is a precision timekeeping device used for measuring elapsed time with high accuracy. This tool uses the browser's high-resolution time API (Performance.now()) to provide millisecond-precision timing. It supports lap timing, which allows recording intermediate times during a continuous timing session, commonly used in sports, fitness, and performance measurement.
Best Practices• Use for short-duration timing sessions for best accuracy
• Avoid switching browser tabs during timing as it may affect precision
• Record laps at consistent intervals for meaningful comparisons
• Consider browser limitations for very long timing sessions
• Use lap timing for interval training and performance analysis
