【實用運動app】Simple Sprint Timer|最夯免費app-綠色工廠好玩App

Simple sprint timer is a tool used to track and compare times while training. Good for timing the 40 yard dash, 100 yard dash, base running in baseball, and any other sprint you are training for. Very easy to use - press run when the runner starts and release when the runner crosses the finish line. You can email your results when you are finished. After 10 sprints, press reset to start over.
