I think WhatsApp is very useful app for me and for everyone. It is becoming a very popular social media app. It is also a very good entertaining app also. You join some of the WhatsApp group. They send you every news updates, funny videos etc. But there are also some misuse of this app. Sometime people send you fake news, fake pictures which you most of the times believed.
So its not sure everything you received on WhatsApp is so genuine and true. It is very useful when you need to make some free audio or video calls. You can message any of your friends, relatives so easy and quick and send them any kind of multimedia files. The layout and design of WhatsApp is boring. The overall concept of WhatsApp is so good.
