Even though an official Twitter client isn’t yet available on Windows 8 platforms, there are several third-party clients available either for free or with a shareware license.
Twitter+ is a mobile Twitter app for Windows 8 that provides you with a Modern interface to easily browse the popular social platform.
The application, however, isn’t a full-featured Twitter client, but only a GUI for the mobile version of the website, so you won’t get any settings or personalization options. It just lets you browse the mobile Twitter from the Modern UI.
The application is available for free and works on all Windows 8 versions currently on the market, including x86, x64 and ARM builds, so Surface RT owners can also install it.
