Jellyfin Mobile on the App Store
Works like a charm This app is the bomb. Totally free, open source server software, easy to use, and looks super sharp. It took me less than half an hour to set up the server software on a 11 year old Windows desktop, and it scanned my 1.5 terabytes of media, grabbing all images, chapters, and descriptions, in only about 6 hours (not bad for the 600kbps internet and old Phenom CPU).
