Tool Guide
Tool Overview
The Online Stopwatch Timer Tool supports stopwatch timing and lap functions. The tool records all start, pause, and lap data, and can export the data to Excel for processing.
The "Item" column in the tool's table supports editing. After completing laps, you can modify the values—for example, in a group long-distance run, you can assign lap numbers to students in order, and after they finish, modify them to the students' names according to the lap numbers.
You can export the timing data to Excel for easy saving and recording. Excel provides more detailed timing data information, such as the recorded time and the timestamp of the recorded time.
