Stopwatch for coaches

Stopwatch for Coaches is a Chrome extension that lets you stop several athletes at the same time, collect split times from each athlete, and quickly see which splits are fastest or slowest. It’s ideal for athletics, swimming, or any sport with multiple athletes, and supports accessibility features such as large font sizes and VoiceOver.

Sport Stopwatch Pro expands the feature set with multi-athlete support (stop more than two athletes at once) and keyboard controls (use the up/down keys to start and stop the clock). The Pro version is available by annual subscription (pricing varies by location), with privacy and terms pages linked for transparency.
