You may know Zepp for sports tracking sensors you can slap on your baseball bat or soccer ball, but its latest tracking involves little more than your phone and a good view of the action. Its game recording and training apps (Android, iOS) are adding a dash of AI technology (namely, computer vision) to analyze your baseball swings, golf swings and basketball shots. If your three-pointer throwing needs work, you just need to point your phone's camera at the court and start capturing. You can share the videos and performance data with others, too, in case you need to prove your skills to recruiters.
