Meanwhile, Viber is quite poor, offering much less, so we can say that Skype is a true winner.When you video call a friend, the data (audio and video) are sent from you to your friend over many different network links between different devices:Īny one of these links can have a problem, although you will mainly care about the ones on your side (the top half of the diagram) because they’re the ones under your control.

You can even find special hardware for Skype, such as microphones, web cameras or headsets. The latter allows you to add several people to one call, record you call, set up various configurations and settings, you can choose premium plans and so on. It doesn’t offer too many features, while Skype has had the time in a decade to gather up lots of interesting and useful features. Yet again, Viber proves itself to be quite limited. Moreover, Viber is still beta testing their video call feature, so we cannot really compare the two. This happens because the app relies on HD voice and improved codecs. As we already said, Skype offers a much better call quality than Viber, both when it comes to voice and to video. As such, the winner of this round is Viber, with the mention that indeed, Skype offers more qualitative calls than Viber.Īnd since we’re here, let’s talk a bit about the quality of the calls too. For you to have an idea, Viber uses something around 250 KB/minute, while Skype definitely needs more than that. You have to pay attention to how much data you are using. However, mobile VoIP is slightly more expensive than the desktop one, since you have to spend on mobile data usage. The very concept of VoIP was intended to be a cheap alternative to calls. Meanwhile, Skype has had quite some difficulties in catering to various mobile platforms, since the developers had to changes all sorts of things. Here, Viber has a definite advantage, since it was conceived primarily as a mobile app. Nowadays flexibility is a key component of everything.

However, it’s normal to be like that, since Viber has just hit the market. Skype is again the winner here, since it has 5 times the number of downloads Viber has. In this case, the bigger the userbase a VoIP app has, the more people you can call, it’s simple. Though popularity is not a warrantee for quality, it is often times an indicator of how good an app is.
