I'm I reading this right? A person who sells an app called "Pedometer" (which tracks your steps) sees iPhones that fit easily in your pocket as the most common size for people who buy the App? If so I'd guess people who measure their steps correlates strongly with people who don't like to carry extra carry bags.
