One inexplicably popular app: Fruit Ninja

Yes, iPhones can make people rich. No,  we are not talking about those at Apple, who brought in their pile of cash selling iPhones. We are talking about those developers and companies who earned their fortunes off of iPhone apps.

So, let's take a look at an iPhone app that made a fortune for its author. We will not repeat all the well-known stuff about well-known apps such as Angry Birds and why they so are so popular. Instead, we consider the 3rd best-selling app from Apple's App Store, a game called Fruit Ninja. Funny name, for an app, right? Nevertheless, this game with a $0.99 price tag was sold over 10 million times.

A simple calculation reveals that Apple customers together have paid  around 10 million bucks for this game. So, what's so cool about Fruit Ninja? Well, the game itself is pretty simple: it allows you to slash the fruits that fly onto the screen using a sword. Blade movement is controlled by finger swipes. This turns out to be amazingly addictive ; people can spend hours upon hours cutting various fruits in pieces.
