The Family Link app from Google helps parents stay in the loop as their child or teen explores on their Android device, and lets parents set certain digital ground rules for their family. … If a child/teen already has an account, Family Link will walk their parent through linking their account to their child's account.
It lets you create and manage a specific Google account for your child. This account is a lot like an adult account - but there are limitations on what the account gets access to from Google. Family Link then allows you to remotely manage a child's device, including things like screentime limits, device location and installation permissions.
With Family Link you can approve or block the apps your child wants to install from the Google Play Store. You can also monitor and limit screen time, including checking out how much time your child spends on their favourite apps, thanks to weekly or monthly activity reports. And, you can set daily screen time limits for their device.
