On the iPhone People Buy Games, Not Books
Summary
For developers, a better return on investment comes from Games, Entertainment and Productivity software, the top three categories of paid software in the App Store. Apptizr’s aggregated data is a gold mine for current and would-be developers alike. That compares to 15 percent searching the games category, which is the runner-up in terms of interest. Apptizr’s report (PDF) comes from the crowd-sourced user data it collects from users, which install the free Apptizr software and “seed” the service by sharing the types of applications they prefer. The Apptizr app then tracks software titles users install on their iPhones and suggests new ones based on an in-house algorithm — Apptizr has offered over 10 million software recommendations to date.
