Can anyone recommend a Mac app for keeping track of my books, CDs, and DVDs to serve as a replacement for #Readerware? Must be able to export data in an open format, to import some vaguely sensible format, and to look up metadata on the intertubes for new items entered as ISBN or UPC bar code numbers. Ideally, but not essentially, it will have an iOS companion that it can sync with so I can have copies of my data in my pocket. Please only recommend tools you use yourself. #Bookstodon
