Apple plans 'more robust' parental tools after iPhone addiction claims

Company says it has 'always looked out for kids' after open letter from investors said it should do more to tackle children's overuse of smartphones

Apple says that it plans to make parental control tools more robust, following investor calls that it must take action against smartphone addiction in children.

Two investors, collectively controlling $2bn (1.48bn) in Apple stock, called out the company on Monday for not doing enough to help mitigate the growing concerns around the negative effects of smartphones and social media on the young, urging it to "play a defining role" in the health and development of children.
