The apps are called Steam Link and Steam Video, and they’ll support both Android and iOS platforms. Coming May 21, 2018, the Steam Link app is the most exciting one and promises to let you experience your Steam library of games on your Android or iOS smartphone, tablet or TV. Steam Link works by connecting your Android or iOS device to a host operating system like GNU/Linux, macOS or Windows, where the Steam Client application is installed, via a wired Ethernet or a 5Ghz wireless network connection. Of course, you must also be connected to your Steam account on the host computer.
