Own It app: Prince William said it's a good thing for digital wellbeing
Prince William said he thinks the new BBC Own It app, external "can only be a good thing for children's digital wellbeing and mental health".
Three years ago he set up something called the Cyberbullying Taskforce, and he's worked with the BBC to develop a new internet safety app for kids.
It aims to support young people who use social media, and helps them to take their first steps online.
