What is the "Apps" section on the left?

My page is in the "App Page" category. One of the sections on the left -- that include "About" and "Photos" -- is "Apps." In this section appears a thumbnail of my web site and the word "Website." Not sure that should be there.

How do I get a link to my web site out of the "Apps" section? And what should go there? A listing of my individual apps?

The page is PhotoCrash Apps. Thank you.
