I have been using whats up for 4 years and whats up always keeps on update his features.
Whats up is awesome you can do lots of thing on whats up like chating, video calling and many more, today whats up its very useful app
You can send every thing like video, message,
Document and information but we cant search
Our friends like facebook, in whats up you can only keep in touch with that person if you have number them if you dont than you cant keep in touch with them in whats up.
Whats up is very good for close our dears one.
