Skype and Viber might be falling under the same category of mobile apps, but it is a fact that their functionality and features vary considerably.

These apps allow you to call and message your contacts for free. Both the apps let users chat only using the internet. You can also set your profile on both the apps. In this article, we will compare the features of both the apps and then find out the winner at the end.

Ease of Use

When it comes to the ease of use, Skype and Viber are fairly easier to use. Skype and Viber are more or less similar as far as the layout is concerned. Viber requires you to verify your phone number and that number becomes your username. Contacts are added automatically from your contact list and if your contacts are using Viber you will be able to chat with them. Also, Viber does not require a password to login. On the other hand, Skype requires users to sign up for an account. You also need a username and password in order to login. Unlike Viber, you need to add your contacts manually, which can be time consuming.


Viber app is completely free. You can send messages and make calls for free to other users. It is also free to download from the Appstore. However, you will be charged when you make calls to landline and mobile numbers across the world depending on your subscription. The service is known as Viber Out and makes it possible for people to make low cost calls to any landline or mobile numbers even if they are not viber numbers. Like Viber, Skype is also free to download. You only need to purchase credits in case you want to make calls to landline and mobile numbers.

Data Consumption

VoIP is normally used to save money on messaging and voice calls. Mobile VoIP is typically costlier than desktop VoIP. Mobile devices need a 3G or 4G data plan in order to make VoIP calls. However, this is not a requirement as calls can also be made through a WIFI network. Generally, Viber is less expensive than Skype when it comes to data consumption. Even so, Skype offers great quality voice and video calls from both Smartphones and desktops when compared to Viber. Therefore, in terms of data consumption, Viber is the winner. But in terms of quality of VoIP calls, Skype is far more ahead than Viber.


An application is not always rated based on its popularity. An app that has a larger user base allows you to make free calls to many people, thereby saving you lots of money. With that said, there is no denying that Skype is far more popular than Viber. This is quite understandable because Skype came first.

Final Thoughts

Both the apps are definitely worth downloading and installing as their features are not very much different from each other. Viber is a good app when you want to save money on video and voice calls. If you are using VoIP on your computer or tablet PC, you should consider Skype. But if you are using VoIP on your Smartphone, definitely go for Viber. At the end of the day, it all boils down to personal preference!
