I did a search and read through the ten threads that mention Chromecast.....but didn't find the rudimentary recommendation I seek.

Unlike some clients, the Chromecast can't really do anything without a control app to "cast" to it.

I'm curious whether other users have found a playback app or control app for iOS they like, that can browse all the content on the Asset UPnP server, and then "cast" it to a Chromecast?

(Apologies if I am stating this incorrectly, or if there is such a simple common known way to do this on iOS that I'm wasting bandwidth even asking!)
