Any person who wants to message and FaceTalk the watch must have the free TickTalk App downloaded and all contacts will have to be approved by the Parent/Admin. You'll be alerted of any add requests in the App to ensure your child is only speaking with people that you know. Your child can add other friends with TickTalk's with Add Friends (which you can choose to turn off in your app if you prefer). You will receive a notification for all friends added to keep you in the loop.
