Keep in mind that this is a top grossing app, which means most apps are making a tiny fraction of this. Even if it only took one programmer and four months, which is very unlikely, that's still in the range of a good yearly salary and it won't stay on top without continuous updates and promotion. I'll say it again: the smart way to make money in the app store is to get paid writing apps for other people.
