I am using whats app since few years. it is a very good app for all smartphone users. I am truely impressed by the concept of this app. the logo of this app is ver good. the functions of this app that we cam chat with or friends and relatives, we can also share our good posts to all the users. we can download this app from our playstore. this app can connect many people with us . and it is not paid app it is absoulutely free app. so we all have to atleast try it once.
