Online Stopwatch
Time anything down to hundredths of a second with this simple online stopwatch. Hit start to begin counting, stop to pause, and record laps to capture split times without interrupting the clock. It is handy for workouts, cooking, timing a presentation, or measuring how long a task really takes. Because it lives in your browser tab, there is nothing to install and nothing to sign up for. The lap list keeps every split you record so you can compare rounds at a glance, and the reset button clears everything for a fresh run. Everything runs locally, so your times stay on your device and the clock keeps ticking accurately even while you note down your splits.
