A stopwatch with laps.
Free to use, no sign-up required. Stopwatch is one of 198 tools built into Xenition, alongside a chat that can use them for you.
A stopwatch that counts up to the hundredth of a second and records lap times. Use it for timing runs, workouts, speeches or anything you want split into parts.
Elapsed time is the difference between the current clock and the moment you started, refreshed every 50 milliseconds, so it stays right even if the page is briefly slow. Each lap stores the total elapsed time at the moment you pressed the flag, and the newest lap appears at the top of the list.
Pressing the flag at 01:02.35 and again at 02:10.80 lists “Lap 2 02:10.80” above “Lap 1 01:02.35”. The second lap on its own took 02:10.80 minus 01:02.35, which is 1:08.45.
A split is the total time from the start to a point, while a lap time is only the stretch since the previous mark. This stopwatch lists splits, so subtract one from the next to get a single lap.
The display shows hundredths, but human reaction time adds roughly 0.1 to 0.3 seconds at each press, which is why official sprint results use electronic timing.
You do not have to open Stopwatch to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
