Snapchat is a very popular app that many teenagers use. On Snapchat you can take pictures using crazy filters that recognize a human face and then add crazy things like dog ears, stars, hearts, etc. You can also talk to your friends and send them the weird pictures. In Snapchat the conversations are deleted after they are seen unless you or your friend saves them, which if I’m being honest, is pretty useful. I like this app because I can take funny pictures and I can talk to my friends.
