Try the free Family Link parental controls app from Google. Whether your children are younger or in their teens, the Family Link app lets you set digital ground rules remotely from your own device to help guide them as they learn, play, and explore online. For children under 13 (or the applicable age of consent in your country), Family Link also lets you create a Google Account for your child that's like your account, with access to most Google services.
