The Facebook is one of the most usable app . Facebook is getting most popular in today’s life.the owner and creator of Facebook is Mark Zuckerberg, I want to say very very thanks for creating Facebook. This is a social networking app.This app can connect people at any end of earth. Peoples have to create their Fb id( FACEBOOK ID) first, then he/she will able to use it. We meets new peoples and chat with them, we can send a friend request and when they accept our friend request , then you can start chat with them.it is very amazing to chat with new peoples and make friends to peoples of another country or another state, and chat with them., it really refresh your mind.It entertains me everytime by watching videos and pictures in it. it really awesome. You can use it by their website ( https://facebook.com) or you can download its app on play store in your mobile. Thats all thanks
