KiK is a Canadian app that allows users to instant message each other. While you can use the app to chat with people you know, it also allows contact with strangers in different chat rooms. For the most part, you are able to remain anonymous on KiK if you choose as you sign up with an email and not a phone number. The minimum age for using KiK is 13 per the app's guidelines. This app should always be used under supervision because teenagers have the ability to make an account and chat with strangers all over the world. This can be dangerous because you never know who is on the other side of those messages.
