Is it possible to export my website to a native iOS/Android application?
Mobile App Generator exports a website to plain .html pages so that PhoneGap can compile it into native mobile apps.


  Mobile App Generator assists in creating native multi-platform
  PhoneGap mobile applications for Apple iOS(iPhone, iPad), Google
  Android, Palm, Symbian, BlackBerry and more.


If you want to manage the website through mobile App then take a look at this module Drupad
