Difference between WhatsApp and Skype

What are the differences between these two platforms?

WhatsApp and Skype are two front runners employing VoIP technology. They are so ubiquitous in the modern world that people will mistake you for a caveman if you say that your smart device doesn't have either one of them. 

Skype can be rightfully crowned as the pioneer of video calling. WhatsApp, in its inception, was more of a chatting/messenger app. While the former is preferred by a desktop user, who wants a sophisticated mode of communication that offers better clarity, the latter makes personal communication easy through mobile phones. 

Another major difference is the ease of access to contacts in WhatsApp compared to Skype. This is due to the reason that it is enabled easily through the contact list on your phone. In Skype, such details like Skype username or nickname must be shared beforehand and it can be quite tedious for a first-time user. 

In terms of call quality, Skype is a notch above WhatsApp as it employs its own codec for call encoding. So much so that Skype has come up with a feature called HD voice. This in turn has been cited as the reason for Skype consuming more data than WhatsApp. WhatsApp has a user base of over 1 billion, which is 5 times more than that of Skype.
