What's recommended for media-library tracking software? My wife is using an iPhone app for logging our books and discs. But the library is isolated to the app; it's not shareable online or readily synced to my phone. Is there anything good now? Ideally, it would have an iOS app component that scans UPC codes, and able to share the library via the cloud or website. If it interacted with Emby or Trakt.tv, that would be great. Doesn't have to be free.
