Steam have announced that they are releasing two new apps for both Android and iOS - the Steam Link app, and the Steam Video app.
Steam has historically only been available on PC and Mac, but the Steam Link app will allow users to stream games from their PC / Mac to a mobile device. You will need to be connected to a host system, but the app will free you up to play games wherever you like as long as you are connected to the network (either via 5 GHz WiFi or Ethernet).
This could be particularly handy for users with a great TV/audio set-up that is in a different room to their computer. The app is compatible with Steam Controllers and MFi-certified controllers too.
The Steam Controller can be used with the Steam Link app
The Android version of the app will initially be released in beta.
The app will be made available during the week commencing 21st May 2018, so there's not long to wait.
Later this summer the company will release the Steam Video app which can be used to watch films and TV shows through Steam. Users will be able to watch content via WiFi, 4G, and also offline.
