I see there is no iOS category yet, so I am putting this into the feature request section:
I just noticed that the Zoneplay app added support for Apple Watch.
This might be a gimmick you could put on your roadmap once everything else has been developed 
Just the basics would be fine for starters: Now Playing, Play/Pause, Forward/Back, Volume Control.
Too soon? 
Yes, that would be cool
Here’s a request for future builds. I’d love to be able to stop/start Roon with my Apple Watch.
Much appreciated for all you do! Roon is the best.
Thanks,

I would also love to see this.
I was spoiled with this feature (by iPeng). It would really be nice to have it again, in Roon,
Forget Apple Watch support. Give me Siri support. “Hey, Siri, play Miles Davis Birth of the Cool with Roon”
Siri’s reply: Hey dummy turn down the stereo so I can hear you.
Please basic functions for Apple Watch. Like next, prev. Stop, pause, louder, softer.
I would like this as well - would be handy for poolside control, etc.
Would love to control pause, play, next track, and previous track from Apple Watch. Thank you!

In terms of simplicity, mine would be just a single play/pause button with the crown used for volume.

I’d like to add my thumbs up to this request!
I suppose Force Touch could be used to pick a zone to keep the main screen simple.
Agreed, feature requests could certainly grow but that’s what the product backlog is for 
That would be awesome, just the simple controls would be immense.
+1 for this - even if basically the same as other media players / radio apps.
