Never try this kind of applications, they won’t work on Facebook. These applications might give you un-wanted surprises like posting some spam links on your wall or your friends wall. Just imagine how many of your friends will fall for that silly looking spam link on your wall.

Facebook doesn’t allow tracking the profile visits data. Any application which is developed to track such data will be taken care of, before it actually tracks anything meaningful.

Can I see who’s viewed my profile? There’s a group or application claiming I can find out who has been viewing my profile.

Facebook does not provide applications or groups with the technical means to allow people to track profile views or see statistics on how often a particular piece of content has been viewed and by whom. If an application claims to provide this functionality, please report the application by going to the application’s About page and clicking “Report Application” at the bottom of the page, or by clicking “Report” at the bottom of any canvas page within the application.
Applications you use may ask for permission to access content from your News Feed and Wall. Granting this permission does not allow applications to see who has viewed your profile. It simply allows applications to see which friends have interacted with posts, such as which friends liked or engaged with a particular wall post.

So, If you come across any such application, stop sending invites to your friends or posting on your wall and report the application to Facebook.

Here you’ll see an option to turn off all the platform applications. This will make your profile inaccessible to all other Facebook applications and thus you won’t see and invites or wall posts.

To block any specific application which you are not interested, just go to the application home page and click on ‘Block application’ and that app is blocked.
