As the title states, are there any Android apps that can directly read the Calibre database files? Not via OPDS or any other intermediary, just the db itself. I've poked around a fair bit, both here and on the greater interwebs, and my method of library management must be fairly uncommon, as I can't find any answers, or anyone else asking the same question. The closest I've seen is that Calibre Companion says it can manage your device library, but I wasn't sure if that meant it could read a Calibre library stored on a device, or if it just created its own library on a device.
