"On Monday, May 7, Apple approved the Steam Link app for release", reads a Valve statement. After initially approving the Steam Link app for the App Store, Apple has revoked its approval due to "business conflicts". Ultimately, that appeal was denied leaving the Steam Link app for iOS blocked from release. Valve planned to roll the app out on Android, in addition to iOS and the Apple TV. Aside from the use of GameStream, the main difference between Steam Link and Moonlight is the latter only works with Nvidia GPUs, the former works with Nvidia and AMD. The app utilizes Nvidia's GameStream protocol to stream games from a compatible PC to a mobile device with the app installed.
Apple is fully focused on selling apps, but allowing Steam Link on to the store means enabling a free app to be used to access thousands of games on a different platform.More news: 10-year study shows obesity increases risk for 12 cancers
Valve is understandably hacked off having spent many hours on this project and the approval process. According to a report from Sensor Tower, the new App Store design brought an 800% increase in downloads for Featured apps. I was looking forward to testing out Steam in-home streaming once again on my iPad, but unless Apple changes its mind, we won't be getting that opportunity.

For those unaware, Apple has not yet given a major visual bump to its Mac app store ever since 2011.
