Technical FAQ
How accurate is the timing engine?
UtilVox uses performance.now() and requestAnimationFrame() to synchronize with your display's refresh rate. This provides sub-millisecond precision, far exceeding standard setTimeout-based timers.
Will it continue if I switch tabs?
Yes. While most browsers throttle background execution, the underlying logic uses absolute high-resolution timestamps. When you return to the tab, the display will instantly catch up to the true elapsed time.
Can I export my session data?
Absolutely. Use the CSV or TXT export buttons in the sidebar to download a complete breakdown of every lap, including split times and statistical performance metrics.
