I am using WHATSAPP since 2013. I am very happy with this application. There are some points I would like to share .
The concept and design - The developers of this application has done a very good job. The purpose of this application is connect people and the developers designed this application according to that. This application is so user friendly that any one can use this very easily.
The free service - The service of this application is absolutely free. This makes this application even more popular. This free service is for everyone who have a phone and a sim card.
Features - Whatsapp is upgrading itself day by day. They believes in improvements. It gives all its users regular updates. I just need to update this application regularly. That’s it.
I am very happy with this application and this application is highly recommended from my side.
Thank You.
