The Steam Link App will let gamers experience their games on Android or iOS-based devices provided that you have a 5 GHz wireless connection or a hardwire ethernet connection.
The Steam Link app will support use of the Steam Controller, MFI controllers and other controllers available on both platforms, Valve said in a press release.
It remains to be seen whether Valve is turning its back on the Steam Machines in favour of focusing on devices everyone owns, but last month the company removed the listing for Steam Machines from its store.
Steam is primarily intended as a means for downloading and playing games on a computer, but Valve has extended that further over the years-Steam Link allows you to stream games to a TV over your local network.
So at best, you'd be able to play your Steam games around your living space. In addition to phones and tablets, the app will also be available for Android TV. Both apps will be free. The Steam Link app is set to launch on May 21, 2018. The app lets you stream Steam's library of movies and TV shows and download content for offline viewing. While functionality will likely be similar, performance through the Steam Link app probably will not offer the same 1080p, 60 FPS stats of the Steam Link box.
As for the Steam Video App, it will be arriving sometime later this summer.
