Beginning this fall with iOS 12, FaceTime will support audio and video calls with as many as 32 simultaneous participants. Members will be able to drop in and out of group call as necessary, much like an ongoing conference call.
The announcement could be a blow to dedicated conference call services like Zoom, as smaller organizations may choose to rely on the the built-in FaceTime rather than paying for a more feature-filled service.
On more populated video calls, the FaceTime app will automatically focus on and enlarge the "tiles" of users, and vary the size of individual tiles when someone else talks. You can also choose to lock focus on a certain user, and apply filter effects, Animoji, and the new Memoji to yourself while live on a call.
Group FaceTime will work on iPhone, iPad, and Mac, and you can answer on audio using the Apple Watch.
