Is the online stopwatch accurate down to the millisecond?
Yes. Our tool leverages the `performance.now()` API native to modern web browsers. Instead of relying on error-prone interval loops, it syncs directly with your device's high-resolution system clock, ensuring zero drift and perfect accuracy.
Will the alarm sound if my computer is locked or asleep?
If your computer goes into a deep sleep mode, browser activity is suspended. However, once you wake the device, the timer instantly calculates the passed time. To ensure the alarm rings exactly on time, disable sleep mode while the timer is running.
Can I use the stopwatch for workouts?
Absolutely! The lap function is designed for athletes. It tracks your overall time while simultaneously calculating 'Split Times' (how long each individual lap took). It even color-codes your fastest lap in green and slowest in red.
