Apple recently added warning labels to apps in the App Store that include in-app purchases. This comes shortly after the settlement over in-app purchases when families sued over their children buying thousands worth of in-app purchases.
In-App purchases may be ideal for applications that adults use, but children may not know that they are spending real money when playing a seemingly free game that locks out features unless they make a purchase. Personally, I’d rather pay $2 or $3 for a full-featured game if I know that the developers aren’t going to nickel and dime me out of several more dollars later.
It doesn’t stop anything, but as iMore reports, it gives Apple a better legal argument.
