+This is actively being developed and will be available on the App Store soon - check back here or on [our website](http://limelight-stream.com) for updates.
 
 We understand that Limelight users are eager for the opportunity to stream their Steam collection to their iOS devices. Limelight for iOS is in the testing stage and preliminary versions are available for beta testers.
 
 In the meantime, check out the existing versions for [Android](https://github.com/limelight-stream/limelight-android) and [PC](https://github.com/limelight-stream/limelight-pc). Also, a client for [Windows and Windows Phone](https://github.com/limelight-stream/limelight-windows) is in the works and actively being developed.
 
 Please be patient as we work to bring Limelight to more platforms.
