This means that none of your private information will be sold or even accessed by anyone other than you and your interlocutor. This protective mode is turned on by default. This app can’t read any of your chats because they use end-to-end encryptions. Besides, the app can show push notifications in real-time. The contact lists, chat history, and new messages are easy to access. Viber is designed with simplicity in mind. All information from the smartphone gets automatically synchronized to the PC, allowing you to send messages from your computer. The only requirement is that you already have Viber installed on your smartphone. This app also enables users to utilize voice and video calls via their desktop computers. If you want to call people without the app installed, you may use Viber Out - an option with a pricing plan that allows for cheaper calls to non-users at a low rate. There are no limits as to who you may call, as long as they use the app. Viber allows for audio and video calls on 3G or better connection or WiFi.

To add something extra, there’s a feature that allows for doodling as well.

Group chats can have up to 100 participants. The options include texts, audio clips, videos and photos, and emoticons. When it comes to its messaging features, Viber is no different than other apps.
