Facebook is the most popular social media app. The app is very easy to understand for most people. It's a very good way to keep up with your friends and even your family members that don't live near you. It is very easy to use, it's nothing complicated. I love Facebook myself because I get to keep up with my friends and see what kind of things they like.
Snapchat is the third most popular social app. I like it because It helps me see the people I'm talking to and what their up to at that time. What I also like about it is that it deletes the picture right after they see it and you can determine how many seconds they can see the picture. It is very easy to understand when you download the app, like it will take you two minutes to know the app.
