How does this tool work?
Measure time intervals precisely and record important milestones.
Use the stopwatch for sports, cooking, or work. Start the time measurement and use the "Lap" function to mark intermediate times without stopping the running clock. All lap times are clearly logged in a list and can be reset if necessary.
