WhatsApp vs. Viber Free Download – Should You Use WhatsApp or Viber?


WhatsApp and Viber are just two of the emerging instant messaging applications that people use these days to communicate, instead of using text messages.

The two apps let you make and receive calls and messages for free. That being said, let’s compare the two popular communication apps.

WhatsApp is available on iOS, android, Blackberry and Windows Phones. It is an instant messaging text service that allows users to send pictures and videos. On the other hand, Viber is available on various platforms including iOS, Windows Phone and Android. Viber is also available for desktop computers and Mac OS.

Ease of use

WhatsApp is quite easy to use. You need to perform the initial setup using your personal phone number. All contacts that already use WhatsApp will appear in your WhatsApp contact list. WhatsApp must be linked to your SIM card number. It acts more like an in-built SMS tool than an Instant Messaging app. In other words, you cannot use the app on more than one device.

When it comes to Viber, the interface is simple and clean across all platforms. Like WhatsApp, it syncs to your phone contacts, allowing you to see which of your contacts already use the app. While Viber has a clean UI, WhatsApp focuses more on simplicity and straightforward approach. Viber seems to be a little bit more sophisticated in this aspect.

Call Quality

When comparing the two IM apps, the quality of the actual voice is an important factor. WhatsApp voice calling on different bandwidths is quite acceptable. However, audio quality is poor on a 2G network. Even so, the fact that WhatsApp can support voice calls on such an outdated network is an achievement in itself.

Compared to WhatsApp, Viber offers far better audio quality. It offers an HD voice quality feature on almost all bandwidths. However, it performs better on high-bandwidth networks. Additionally, Viber allows its users to connect with people who are not using the service.


WhatsApp is free to download. However, it charges a dollar every year for continued use of the service after the first year of free use. Also, it does not allow ads. Viber is also free and does not allow offers from advertisers.


The two top mobile messaging apps offer their own web clients. WhatsApp offers a desktop client that uses an internet browser, meaning you do not need to install anything else. Viber also allows you to use it on a Windows PC but you need to install a desktop program. So in this aspect, it seems like the game is a draw.

Final Thoughts

Both WhatsApp and Viber share a lot in common, making it almost impossible to tell which one is better than the other. But WhatsApp takes the cake here because the instant messaging app service serves hundreds of millions of users worldwide. The main reason most people install Viber is to get access to HD voice calling, and most of Viber users already have WhatsApp on their mobile devices. Since WhatsApp is also improving on its voice features, users might find no reason to use Viber in the future.
