Auto Kill for Android remote app

I noticed that the Roon remote app will remain active, keeping a wakelock on my phone and tablet which causes rapid battery drain. It would be good to have some sort of auto kill feature after X mins of inactivity. The app BubbleUPnP has this and it helps dramatically. Luckily, my phone is rooted so I can use Greenify to kill Roon remote once the screen goes off but my tablet is not rooted.
