Hi ,
Didn't get it .
ARC app replacing roon app or its an additional one .

It's Roon on the go for mobile devices. You can access your streaming services and local library from your cell phone.
Roon ARC only runs on IOS or Android devices (currently). It can use cell service or wifi. It also allows you to download music you own (i.e. local music) to your phone or tablet for times when you can't connect (e.g. airplane). It's very cool and will likely evolve quite a bit more.
