SharePlay is a feature tied to FaceTime and iMessage that allows users to interact with apps and media simultaneously. It was revealed alongside iOS 15 as a FaceTime feature, then added to iMessage with iOS 16.
The feature has allowed users to watch movies, listen to music, and do Apple Fitness+ workouts together. But it has been absent from the HomePod and Apple TV — until now. The new feature was spotted by MacRumors.
