Click on the app you want. Read this: *FaceTime* It is not actually a face time and your video will not be recorded.Only the end call button works. *Messages* It is using a variable list. You can add your message for other scratchers to see, but they will not know who wrote it, unless you write your username in the message.
Apple FaceTime and Messages of course! Hope you enjoyed! You can request another app in the comments.
