You can’t expect to get better at baseball if you don’t constantly work on improving your technique and skills. The Diamond Kinetics PitchTracker is a smart baseball that helps you make sense of your performances. It can measure 7 metrics, including velocity, spin rate, and time to plate.
One ball can be used by an unlimited number of players. You get an interactive dashboard to see your last session and can sync your video to your pitching metrics. Users will be able to see the complete pitch history and trends. The PitchTracker app requires iOS 11 or later.[where to get it]
