WhatsApp vs. Viber Messengers

Feature Comparison Between Two Popular Apps


If you are choosing between installing WhatsApp or Viber on your smartphone, don’t choose. Install both and try them out until you finally favor one over the other. These apps are so similar, your decision may come down to which app do your family and friends already use. Here is a comparison of the two apps feature by feature to help you decide which is the best choice for you.

The Interface

Viber has a richer interface but it appears cluttered. In contrast, WhatsApp has a simple, clear interface that makes the user feel comfortable and gives the impression that everything is at hand. Viber has an overwhelming library of relatively useless stickers that clutter and complicate the interface. This is one category where the apps differ. Viber’s cluttered interface loses when compared with the sleek and simple interface of WhatsApp.

Voice and Video Call Quality

Voice call quality is an important consideration. Viber has offered voice and video calling for years and is more experienced at it than WhatsApp. Viber delivers HD quality voices that are crisp and clear in high bandwidth connections. WhatsApp came to voice calling later than Viber, but it delivers decent voice quality.

Voice quality has many aspects affecting it, apart from the services' codecs and perceived quality. One important factor is the network connection. In this respect, WhatsApp appears to be more robust, especially in re-establishing dropped calls. 

Both Viber and WhatsApp offer video calls. There doesn't appear to be a distinguishable advantage of choosing one service over the other for video calling.

The Cost

Viber costs nothing to download and install. Viber-to-Viber calls and messages are free, no matter where the person is located. Calls to numbers that don't use Viber are made using the https://account.viber.com/en/Viber Out service, a service that connects you to anywhere in the world for a low free. Viber offers hundreds of decorative sticker packs for use when messaging, some of which are free and some of which cost.

WhatsApp did away with its $1 a year fee in 2016 and is now completely free to download and use for messaging, voice and video calls, which use your internet connection rather than a cellular connection. WhatsApp Calling can place calls to phones worldwide. The only costs occur when you exceed your data limit.


Both WhatsApp and Viber have penetrated the market and offer apps for nearly all mobile operating systems on the market. They also both offer versions for computers. Both offer a desktop app you can install on your machine. 


Technically, a group places a number of people in a common location where everyone can post messages to everyone else and sees what anybody posts. This is a great way of communicating en masse and getting information through efficiently. Both apps allow groups, but the implementation in both could use some improvement.


What'sApp prides itself on end-to-end encryption of your messages and calls. You and the person you contact are the only people who can read or listen to them. Viber also provides end-to-end encryption for your communications, so both apps provide strong security for users.

And the Winner Is...

With Viber, you can share your screen with another Viber user during a chat. With WhatsApp, you can send documents up to 100 MB.

As you can tell, these two apps are similar in services, features, security, and costs. Your choice may come down to which service is used by your family and friends and your personal preference for the interface design. It's safe to say there are no losers here.
