Viber is a free Android application that lets users stay in touch with family and friends by sending text messages and making phone calls. The voice calls are free in case you have an internet connection active. In terms of UI design, once you install this app and launch it, you will notice a modern and clean layout. The messaging system allows you to send text, files, add GIFs, and stickers.
Users can create communities that are nothing but group chats with an unlimited number of participants. Holding conversations over the Internet might put your privacy at test, and Viber protects you by using end-to-end encryption. These encryption keys are kept on the devices involved during a conversation, and nobody else can decode the data. Sometimes you might say something that is not that important, and this service allows you to remove seen messages.
You can extend the capabilities of this application by using chat extensions to find and share videos, music, and more. You can manage your account from other supported platforms, and all your information and chat history will be synchronized.
