This app is supposed to consult a long string of databases, but all I get when I input all valid URLs is the word "Null".
There appears to be no real checking of databases and no results for the URLs under investigation. Either its a scam; or simply defective and poorly-written.
When I follow the app support links, it takes me to Carnegie Melon University homepage, so I would tend to think it is a scam. Too bad! It was a good idea.
