SprintLens is a photo finish timing app designed to measure times with high accuracy using just two smartphones. It is ideal for track and field, swimming, and other timed sports. Perfect for team managers, coaches, and club advisors! As a runner myself, I created this app from the perspective of athletes and team managers who want precise and flexible timing tools. Place one smartphone at the start and another at the finish. SprintLens combines the start signal with high-frame-rate video recorded at the finish, allowing you to review the exact finish moment frame by frame. It is designed to make timing more accurate and easier to understand in situations where stopping a manual stopwatch is not enough, such as sprints, swimming races, time trials, practice sessions, and school club activities. 【Key Features】 ・Measure times using two smartphones placed at the start and finish ・Timing linked with the start signal ・High-frame-rate video recording at the finish ・Frame-by-frame video review to determine the finish time ・Useful for sprints, 100m races, time trials, club activities, and practice sessions ・Create a timing setup using only smartphones, without dedicated photo finish equipment 【Recommended For】 ・Track and field and swimming practice ・Accurate timing for 100m, 200m, hurdles, and other short-distance events ・Recording practice results for teams and school clubs ・Situations where manual stopwatch timing is difficult ・Reviewing the exact finish moment on video SprintLens is designed to help you check the time from start to finish using video and synchronized timing data. ※Timing accuracy may vary depending on the device, frame rate, network environment, and recording conditions. ※This app is not guaranteed to replace official photo finish timing systems used in sanctioned competitions.
