Whatsapp is the best messenger app among everyother messenger app present in playstore. It is very simple, fast, lag free, add free. Now from 2016 the Yearly fees which was charged earlier by whatsapp has been permanently removed. Now it is free for lifetime. It is although free but have many extra ordinary features like personal chat, group chat, message broadcasting, etc. Now a days whatsapp has also introduced voice call feature. Thus has saved my lots of money which otherwise I have to spend in purchasing call talktime coupans.
