How to know who's viewed your profile?

There is an app on Facebook for that. I tried it before but the app was never accurate like it missed 99% so I guess that app was just for fun.

There are several facebook applications that let users to see who viewed their profiles. However, not all viewers are listed. Sometimes, it only shows the top ten or top twenty viewers of your facebook profile. However, i just don't know if it shows the truth and i never really tried anyone of them. In fact, i just don't care who really view my profile. In addition, i just don't like for facebook to add trusted application who will track your facebook profile day by day.

to be honest I never asked the question if there is any way to know who and how many people have visited your facebook profile every day. However in my opinion, you can track visits to their profile, perhaps even resorting to the use of special software. That said, however, I can tell you that you're not the first person I've heard of this. From what I can deduce that this curiosity is present in many people. So I believe that sooner or later, (if not already possible) there will be a guaranteed system to remedy this problem.

I think there is an 'app' on facebook that you can add to track it. FB already tracks who you view constantly by who they put up on your News feed. Notice it is most always the people you look at constantly or message?
