My answer to What is the optimal description length in the Apple App Store? on Quora
Have you ever come across one if those ugly, long pages advertising an ebook—the ones that bang on for dozens of paragraphs with bullet points, pictures, testimonials, headings, more testimonials, more bullet points and so on?
Guess what: they work! The general format is called a “sales letter”—http://en.m.wikipedia.org/wiki/S...
We know they work because people have been split testing them for decades.
I imagine iPhone developers have discovered that the same trick (way too much information) works for 99 cent purchases on the App Store.
