Apple's Pay Once And Play aims to limit in-app purchases
It's the sort of thing that happens when five-year-old Danny invests in a worrying amount of virtual weapons on Zombies vs Ninja in mere minutes.
Apple's new Pay Once And Play feature aims to make it easier for Danny's family to be alerted when a bank account attached to a device is at risk from excessive shuriken (a type of dart, in ninja vocab) purchases.
The new section promotes games that don't have any in-app purchases on the front page of the App Store.
Pay Once And Play is organised into three sub-sections; recent releases, blockbuster games and App Store originals.
Apple has recently dealt with numerous complaints over the nature of so-called freemium games being advertised as free downloads while effectively hiding major features behind in-app purchases.
Other companies have had issues with the way they make users aware of extra costs.
In September, Google was told to pay more than $19m (£11.6m) to settle a formal complaint over unauthorised in-app purchases.
The complaint came from the US Federal Trade Commission (FTC) which said Google should do more to warn people about how much they were spending.
The settlement required Google to tell all those who made in-app purchases about how to get a refund.
Google Play users on Android devices now receive a warning that a game "offers in-app purchases" before downloading.
In-app purchases are listed next to an app's details (ratings, downloads, file size) and on "App permissions" screen.
