HOW TO Copy a fb app?

Hey BHW, haven't posted here in months but about to start up again.

I was wondering if anyone could tell me how I can make a direct copy of a simple fb share app for a cpa email submit...

I use a program called HTTrack to copy websites.

I am kinda new to FB but I see an app that I want to copy and adjust, and promote via spamming. Thanks guys! I love you all.

Apps are generally made up of php, which u cant copy
