What's app is a social networking application mainly for Android users. In a WhatsApp we can chat for free. This is become very popular now a days. Mostly everyone have WhatsApp account . who is having smartphone they are using WhatsApp. In a WhatsApp we required a phone no.
Actually in our contact list all are automatically added with us in WhatsApp if they having WhatsApp account. But now some people are misusing this like sending vulgar images videos. So I request to WhatsApp company to do this particular problem. And also we can make call to with this . so all of all it is nice. Hope this review is useful thank you
