While the application falls short of tracking pageviews (which would violate Facebook’s privacy policy), Stalker Check does keep track of your friends’ public interactions – including wall posts, comments, likes, gifts and more – to determine which of your buddies is most, um, interested in your life lately.

 

Another killer feature: You can also track your friends’ biggest fans. In other words, if you think someone is spending too much time on your significant other’s Facebook page, Stalker Check provides some hard evidence.
