I'm looking for an app that will help me track my HC and TPB collection. I found goodreads and comicgeek and both look like they are ok for adding each book to a collection, but what I really want is an app that can tell me how much I've read. It could be pages or issues or whatever but I'd like it to track some of those other things and not just be a list of all the books I own.

Does anyone having anything they use currently, even if it doesn't exactly fit what I'm looking for?
