Very useful app as I am a follower of a great number of series on the television, and sometimes forget which episode I have seen, or not, or worse, that I buy a DVD that I already have. This will not happen again, as I am now always updated with the latest information on my DVD library, and thanks to the Cloud, I have the information with me on my iPhone and on my other devices. The team behind the app is very reactive and helpful. If there is some information missing, they update the app immediately, and if there should be any kind of problem like the one I had with some missing episodes, they helped me up, and solved the problem very quickly. I am very satisfied, both with the app and the team.
