I have been mentioning this topic in a related thread (/forum/general-discussion-and-questions/nl-and-chromecast-audio#post-2080300), but worth to elevate.
With Chromecast becoming universally supported by most B&O products, I would be curious what apps for IOS colleagues are using to stream to chromecast. Spotify and TuneIn are obvious.
However, I have not found any good DLNA app for IOS that allows streaming to chromecast audio devices. VLC has still not implemented chromecast streaming. I dislike the GUI and UX of allcast, goodplayer or C5.
Would be curious to learn what others are using for casting DLNA to chromecast.
