Viber

Viber is a cross-platform communication application that enables users to send text messages, make voice and video calls, and participate in group conversations over an internet connection. Developed by Rakuten, it prioritizes end-to-end encryption for all personal communications, ensuring that only the sender and receiver can access the content. The service operates on mobile devices running iOS and Android, as well as desktop computers through Windows and macOS applications, with full synchronization of chat history, contacts, and call logs across all devices. Users can initiate one-on-one or group voice calls with high-definition audio quality, and video calls support up to 50 participants in a single session. The platform also offers a feature called Viber Out, which allows users to place calls to traditional landline and mobile phone numbers at competitive rates, useful for contacting individuals who do not have the app installed. For messaging, Viber supports text, photo, video, file sharing (up to 200 MB per file), location sharing, and the sending of voice messages. A rich library of stickers and GIFs is available for expressive communication, and users can create custom sticker packs using their own images. In addition to basic messaging, Viber provides Communities, which are public or private groups that can host thousands of members. These communities function as social spaces where administrators can broadcast messages, moderate discussions, and share multimedia content. Community members can interact through replies and reactions, and the feature supports polls and announcements. For businesses, Viber offers a dedicated Business platform that enables companies to create verified accounts, send promotional or transactional messages, manage customer inquiries
