Quitting Roon Arc

I think a easy question but help is appreciated,
I got Roon Arc working, but how do i quit it? It takes op full screen on my phone and i don’t seem to be able to quit it,
Many thanks

You can “force” quit ANY app on iOS that doesn’t have a quit action of their own. Fun fact: most don’t…

On an iPhone with a home button, double-click it. Then swipe up in the app you want to quit, like ARC.

On iPhones without a home button, gently swipe all the way from the bottom until you see a parade of currently-active apps. Again, swipe up in the one you want to quit.

Note that this way of quitting apps has been available a long time already.
