Swing, an AI-based Tennis App, Allows Players to Track Their Stats and Improve Their Games

When he was a graduate student in statistics at Columbia, Swupnil Sahai considered doing his doctoral dissertation on the statistics of tennis. As an avid tennis player, he wanted to create an easy-to-use app that amateur players could use to track their games. He imagined creating something for iPhone and Apple Watch through which players could tally their scores and stats, log their workouts and analyze their swings.
