iFart is a great example of what sells on the App Store. It’s the perfect app for conspicuous consumption. The app has had huge success with respect to sales as well, bringing in a reported $10,000 in a single day.
“Joel Comm, developer of iFart Mobile, published download statistics of his app, and this week it stood at No. 1 overall with over 13,000 downloads.”
If anything, this should serve as an example of how to make money with an iPhone app.
