Xbox Family Settings app
Built for the console in the living room, and handier than digging through menus on the TV. You set a screen time schedule for each child, and the requests flow both ways: your child can ask for more console time or for a new friend to be added, and you answer from your phone.
That request model is what makes it fit older kids. Instead of a hard stop mid-match, a teen can ask for twenty more minutes and you can say yes without walking downstairs. Spending history is visible too, which takes the guesswork out of in-game purchases without needing to read anyone's chat.
