The Steam Link app, slated to launch the week of May 21st, allows gamers to experience their Steam library of games on their Android (phone, tablet, TV) and iOS-based (iPhone, iPad, Apple TV) devices while connected via 5Ghz network or wired Ethernet to a host system (Mac or PC), with Android access initially offered in beta. The Steam Link App will feature support for the Steam Controller, MFI controllers, and more across both platforms.
On Monday, May 7th, Apple approved the Steam Link app for release. On Weds, May 9th, Valve released news of the app. The following morning, Apple revoked its approval citing business conflicts with app guidelines that had allegedly not been realized by the original review team. Valve appealed, explaining the Steam Link app simply functions as a LAN-based remote desktop similar to numerous remote desktop applications already available on the App Store. Ultimately, that appeal was denied leaving the Steam Link app for iOS blocked from release. The team here spent many hours on this project and the approval process, so we're clearly disappointed. But we hope Apple will reconsider in the future.
Later this summer, the Steam Video app is targeted for release, allowing users to enjoy the thousands of movies and shows available on Steam directly via their Android and iOS devices over Wi-Fi or LTE. In direct response to customer feedback, it will offer the ability to enjoy content in offline and streaming modes.
