iOS 7.1 has a new warning message for in-app purchases, to make sure you are aware that unless you change settings, approving in-app purchases allows you to make as many as you like for the following 15 minutes.
In-app purchases are increasingly controversial, with parents worrying about kids going on spending sprees, and the European Union planning to legislate over the meaning of ‘free to play.’ Apple introduced parental controls for in-app purchases along with iOS 4.3 in 2011, but the 15 minute period after approving app purchases resulted in the company being sued by parents, who said this failed to prevent children spending lots of money.
iOS purchase settings have not been changed, but this popup message is new, and makes it easier to see how you can change your purchase settings. The 15 minute window is useful for many people, but you can also disable in-app purchases, or require a password for each one. This is a clear improvement for parents in iOS 7, making control settings more visible.
