When iOS 12 launches this fall, you’ll be able to perform a group FaceTime call with up to 32 people simultaneously. The Group FaceTime news came out of WWDC 2018 today, and members will be able to drop in and out of a call, and there will be support for both audio and video calls.
When members begin speaking, the FaceTime app will automatically make their tiles larger, and then get smaller again when someone else talks. You can also choose to lock someone onto the window, and apply filter effects, Animoji, and the new Memoji while live on a call.
Group FaceTime will work on iPhone, iPad, and Mac, and you can answer on audio using the Apple Watch.
