Prism just added the ability to customize streaming transcode quality based on network type (local/remote/cellular) and it works great to save data when you’re cellular only, but still get full original quality (lossless in my case) when you’re on wifi. And it has full CarPlay support. I don’t store music on my phone anymore I just stream exclusively from my Plex server using this app and it’s great, I highly recommend it.
