I'll put in another vote for Audirvana. I use it exclusively on a mac mini server and run it from the very good iPad app. Mostly playing local files stored on a NAS but I do use Tidal some. You don't have total control of A+ from the app but it is excellent for playback. Sound quality is excellent.
I have used Roon a lot and I think the interface is terrible. It is so convoluted and cumbersome to navigate. To me, simplicity is king and A+ is way way ahead in this regard. Roon does have a little more flexibility in terms of browsing Tidal, but I don't think it is fun to use. FWIW this is coming from someone age 33 so it is not like I am a geezer struggling to use new technology!
