The BBC has launched a mobile app – Own It – with a Beeb-approved interface aimed at keeping kids safer online when using baby's first smartphone.

The app's qwerty keyboard is meant to track the child's mood and offer advice as they write. This will include warnings if the app decides a child is sharing too much information or sending something potentially abusive. It will also offer links to advice and help sites "if their behaviour strays outside safe and sensible norms".
