Laps that tell you something
Each lap is shown with its own time and the running total, newest first. When you have two or more laps, the fastest one is marked in green and the slowest in red, so you can see at a glance where you gained or lost time on a track, in the pool or in a speed cubing session.
When you are done, copy the table straight into a spreadsheet, or download a CSV file that opens correctly in Excel and Google Sheets.
Accurate, even in the background
The stopwatch records the moment you pressed Start and calculates the elapsed time from the system clock, instead of counting ticks. Browsers slow down hidden tabs, but the time shown when you come back is still exact. The start time is saved on your device, so a reload does not lose your measurement.
