WhatsApp messenger, which has more than a billion users worldwide, has finally got a desktop version of the application for computers with Windows and OS X operating systems. This step, which was expected from the program developers several years ago, will allow WhatsApp to compete with Viber , Skype and other services that can be used for a long time both on mobile devices and on computers. The application supports Windows 8 (and higher) and OS X 10.9 (and higher). The desktop version can be obtained by downloading it from the official website of the developer. After installing the application, you will need to scan the appeared QR code using your own smartphone so that the desktop client can synchronize the entire history of correspondence from the mobile client. A serious drawback of desktop options is their dependence on a smartphone connected to the Internet, where a messenger is also installed. The ability to chat in chats and groups, correspond with individual users, send emoticons, files, multimedia, and so on through the desktop version of the application is similar to mobile.
