Whatsup is an application where you can call , chat , share and react , I installed this app years ago , and till now I have not gone boared of it .
this app is user friendly there is no need to read a manual to operate this app , convineint we can say . you can send your private information too to ur trusted once as it is fully secuired and your chats with your friends are secured too .
whatsup is an easy was to connect with your friends in a less time . I personally liked it as it proved to be convineint for me also it dosent cost too much data , a very few amount of data is needed if you just want to chat .to do other things like video chat etc , it will cost you data but the quality of video calling is good so the data costed is worth it .
I would highly recommend you people to install this app in you cell phones as it is free of cost .
