“Infinity Blade” is an action-adventure game for the iPhone that is more than two years old. Just a few days ago the 99-cent app was unranked on Apple’s list of most downloaded apps.
Today, Infinity Blade is in the top 5 on the App Store’s free download ranking. That’s what happens when Apple features your app as “App of the Week.”
More importantly, the app appears to be making more money than it was just a week ago when it charged 99 cents. Like other freemium titles, it offers in-app purchases that help you advance your character through the game more quickly.
