There are several apps and devices that you can purchase to restrict and limit your child's online and device activity.

Disney's Circle is both a device and an app that works with your home Wi-Fi network and lets you manage every device connected to it. With circle you can limit and filter content, set time restrictions and schedule 'down' time.
Cell Phone Agreements
Another idea is to have a contract with your child to set guidelines on device use. It’s important to involve your child in the contract making process. The contract may include when and where the device can be used, device etiquette, knowing your child’s passwords, device inspections and consequences for violating the contract.
