With FaceTime, users can make both audio and video calls, switch between front and back cameras, mute the audio or switch off the video during the call, and add up to 32 people in a group chat. FaceTime also features a noise-canceling microphone, which eliminates background noise during conversations. It's easy to use and requires no setup, making it a convenient way for users to stay connected with their family, friends, and coworkers.
