About the Online Stopwatch
TimeDilo’s Online Stopwatch tracks time with sub-millisecond precision, providing instantaneous lap splits, fastest and slowest lap detection, and automatic memory preservation even if you reload or close the tab.
Automatic state preservation
If you reload the page or switch tabs, TimeDilo automatically preserves its exact running state and recorded lap splits in local storage. When you return, the elapsed time continues seamlessly.
Fractional precision
Choose between 1/10s, 1/100s, or full millisecond (1/1000s) readout depending on your timing requirements for athletics, speedcubing, experiments, or study intervals.
