The Most Expensive App Ever

World's The Most Expensive App Ever as of 29th October, 2015. Previous most expensive app was USD 200 but you have a chance to be a proud owner of the world's most expensive android app ever by purchasing this awesome $400 app. The magic behind this app is, all users who purchase this app will uninstall the app within 2 hours from purchase. ;)
But if you are a millionaire and don't know how to spend money, you can (in)waste your money here.
