If your child is spending too much time in front of their device, you can use AirDroid Parental Control to monitor their activities on their device and in the online world. It has been designed to help parents keep an eye on their child’s activities on their phone, tablet, or laptop. With this app, you can get instant alerts when your kid’s device is used for certain activities, such as excessive screen time or screen sharing.

You can also get alerts when your kid’s device is used for other activities that could be harmful to your child’s physical and psychological wellbeing. For instance, your kid could be using the device to access inappropriate content online. Or, they could be using the device to engage in cyberbullying or other dangerous activities. You can get alerts for all of these, and you can choose to enable or disable them.
