Out of curiosity...

How many other people were directed to this app by a pop-up when opening an app?

I truely do not see a point to this. If the goal was to be challenging, the developers have failed. If the goal was to be fun or entertaining, the developers have failed even harder than before.
It is not fun or entertaining to fling scaled down dollar bills off the screen in the one direction allowed. If the bills all had different marks and folds, then this would be more entertaining.

To most other apps, I might say "this has potential", but I know that even if this app is made one hundred times better, I would not keep it on my iPod.
