Okay all of us know what is whatsapp and what are its features. It was launched few years back and has now conquered every smartphone with the leading application used in the world. I have been using whatsapp and have used the app in iOS, android, and Symbian phones and very familiar with it. I use whatsapp for sending messages and receiving it. Whatsapp enables you to share photos and videos with ease and just now it has included sharing of documents too. Further, I use whatsapp for calling purposes as whatsapp provides one of the best voice over ip service which has unmatched voice clarity and quality. Earlier when I used the whatsapp calling feature, it was with a 2G smartphone but the calls seemed pretty okay like average. However with the time passed, whatsapp calling had improved and now when I call anybody on whatsapp, it feels as if I am calling them through offline calls. The only glitch is loss of connectivity which results in interruption in the calls for few seconds but as soon the connection is resumed, whatsapp automatically connects the call. The application offers unmatched services like end to end encryption using which I know can send and receives messages and calls without any fear of being traced by any hacker or any government organization. Using whatsapp has became a part of my life and now it feels incomplete of I don’t use whatsapp for some time. The easy to use interface and light weight application supports every mobile architecture and hence I have been using it on various mobiles from various brands and operating systems.
