Steam Link App Beta Available now on Android; iOS To Follow
Below you can find Valve's official FAQ. Be sure to let us know in the comments your first impressions on the Steam Link app!
How does it work?
Simply download the app and connect your host computer (PC, Mac, Linux, or SteamOS) via your local network to expand the range of your Steam In-Home experience.
1. Install the app
Download the app on your phone, tablet, or TV for free from Google Play (currently in beta) or the iOS App Store.
2. Pair your controller
The Steam Link app is compatible with a number of popular Bluetooth controllers, including the Steam Controller.
3. Connect to computer
Connect to a local computer running Steam. For best performance, connect over 5GHz WiFi or wired ethernet.
What technology is the Steam Link app using to stream games to phones?
It's using the same Steam In-Home Streaming technology used in the Steam Link hardware. Under the hood, we're doing real-time encoding of H.264 video and sending it over a custom low-latency network protocol, then displaying it on the client.
Which devices can use it?
On the Apple side, we support any iOS device running iOS 10 or newer, and any Apple TV running tvOS 10.3 or newer.
On the Android side, we are releasing in beta so we can do more exhaustive testing. At the start of the beta, we are supporting Android 5.0 or newer.
Can I adjust my settings for better performance quality?
Yes. There is an advanced settings menu option that allows you to tune streaming resolution and bitrate for the best experience on your setup. Over a 5 GHz network, our target is 1080p at 60 FPS with good quality for most scenes. If you have a powerful gaming rig, wired network, and a very good client device, it's possible to stream at 4K 60 FPS.
What about aspect ratio differences and screen sizes?
Black bars on the edges are automatically added to deal with aspect ratio differences, and the video is scaled to handle different screen sizes. On mobile devices you can use two-finger pinch and pan gestures to zoom in as needed.
How much does it cost?
The Steam Link app is available free of charge. No additional charges or service fees apply.
Is my existing Steam Link hardware still useful?
The dedicated Steam Link hardware units support a wide variety of input devices and are specifically designed for low latency streaming to your TV. We are continuing to support the product and believe it is a valuable part of the Steam Link ecosystem.
