The most advanced sports timer in the AppStore! Featured by Apple in the TV-ad "Strength". SprintTimer is a unique sports timer and photo finish app that employs the same techniques as the fully automatic timing equipment (FAT) used at the Olympics. Start the timer and point the camera towards the finish line. The app creates an image where you can scroll to get the time for each competitor with a 0.01 s accuracy*. SprintTimer also includes a motion/human-activated Video Finish for longer races and a Start Sender for wirelessly controlling SprintTimer from another device. SprintTimer is used by coaches, teachers, and athletes all over the world for practice and competition in, for example, track & field, cycling, skiing, speed skating, car racing, rowing, kayaking, horses or greyhound racing. SprintTimer has several advantages over a manual stopwatch: - One person can time all participants - Higher accuracy* - Easier to determine the order - The image and the results can be saved - Can operate "hands-free" when started - The timer can be started manually, with a sound, or remotely from another device *See webpage: sprinttimer.app/accuracy ——— Reviews and Comments ——— "Without a doubt the best App available on the market for sprinters and coaches who want accurate timing to see their development." speedendurance.com "AMAZING" thepegeek.com "Amazing app for physical education teachers or coaches!
