Useless app

I am rich
I Am Rich is an iOS application developed by Armin Heinrich and which was distributed using the App Store. When launched, the screen only contains a glowing red gem and an icon that, when pressed, displays the following mantra in large text:

I am rich

I deserve it

I am good,

healthy & successful

The application is described as "a work of art with no hidden function at all", with its only purpose being to show other people that they were able to afford it; I Am Rich was sold on the App Store for US$999.99 (equivalent to $1,187 in 2019), €799.99, and GB£599.99 (equivalent to £806.54 in 2019), the highest price Apple allowed for App Store content. The application was removed from the App Store without explanation by Apple Inc. the day after its release, August 6, 2008.

why is it useless?
it is useless because you have to pay $1000 for it and all it does is recite those words why would you waste your money on that.
