It's far too easy for children to run up huge bills on phone apps when most default settings allow 'in-app purchases' without asking for a confirmation or password.
Parents who want to stop this should either turn off the default setting or switch on parental controls so that passwords are required for any in-app purchases.
If your child has run up a huge bill without your knowledge, contact the app store or manufacturer as you may be eligible for a refund.
