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.
Apple’s decision seems weird, considering there are other apps available on iOS that allowing streaming from desktop PCs to phones. Valve is continuing to work to get the app out on iOS, so let’s hope that Apple will reconsider its decision.
