I'm currently using an iPhone but I have a Nexus 6p on the way. On my iPhone I use Air Video HD which isn't available on Android. There seems to be clones of it but they don't work with the HD server. I can stream from the Plex app but I don't want o pay for Plex Pass to download. Is there an app that will let me connect to specific folders on my computer to stream and download videos to the phone?
