There are so many high-end applications flourishing in the App Store that can be downloaded by the iPhone as well as iPod Touch users. Some are free while others cost a few dollars. But who would have thought that this simple (and quite boring) application will be the consistent number 1 paid application that works on the iPhone.

The pond simulator called Koi Pond from Blimp Pilot has already been downloaded by thousands of iPhone users to their device. The Koi Pond is worth $0.99 and can be downloaded in the App Store. So far this is the number 1 most paid application in the App Store. And not just for this day or for this week. The pond simulator is number 1 since it was released and up to date.

According to the developers, their creation would let the users imagine that they are gazing in a pond filled with crystal clear water. There are also kois that are swimming around the pond. By using the touch-screen features of the device, you can imagine that you will run your finger on the surface of the pond. And when you do, the koi fish will be disturbed just like in real ponds.
