Well one of these type of highly costly app is going Free !! now for few days.
https://play.google.com/store/apps/details?id=com.iamrich.diamondexpensive.i_am_rich
I took is, since it is now available for Poor
though it mentions in its description section :
"warning! this app is only for the rich people who think that i am rich they can purchase it.
beware poor people and stay away from this app thank you."
Anyway it turns out to be a wallpaper image of a diamond. Now how I make my wife believe that I am Rich ?? She still thinks otherwise.
