Martin Lewis, the founder of MoneySavingExpert.com, said it was "disappointing" that apps aimed at children have been allowed to charge "ridiculous amounts" for extra features. He said:
When games such as My Little Pony, which are obviously targeted at young children, bait kids with 69p purchases of a 'mountain of gems', something is going wrong in the system.
What's really disappointing is it's been allowed to get this far. Apple especially makes a play of only allowing approved apps in its store.
So why does it allow games that can be targeted at young children to charge such ridiculous amounts for in-app purchases?
As always, an OFT investigation, even if it does advise action, will take time. So the most important message meanwhile is to protect yourself.
