Needs a dedicated Apple TV app

Overall, the service is pretty good. I wish there was a proper “guide” to see what’s coming up across all channels at the same time. But what I really want is a dedicated Apple TV app. Using Airplay from the iPhone to Apple TV usually works fine, but why do I have to hold one device hostage in order to stream it onto another device?
