A survey by Flurry has revealed that over the last six months, the preference among iOS gamers has flip-flopped from paid games (premium) to free-but-offering-in-app-purchases type games (often called "Freemium"). Using App Store data on over 90,000 apps and applying its own analytics, the website determined that the freemium model is growing rapidly, moving from 39 percent of all game sales in January to 65 percent last month.
