Now is a difficult period for everyone. Because of the lockdown, my kids are learning online.
But they are constantly at the computer! How to track what children are doing during the day on the computer? I don't think they are learning all this time!

I have installed mac keylogger https://www.refog.com/mac-keylogger.html on my kids computers. Refog Mac Keylogger provides undetected surveillance unlike some of free keylogger programs available. The program can run in stealth mode so children will have no idea their activities are being monitored. That means they won't be able to bypass the program, stop it from recording, uninstall it, or change their behavior to avoid detection.

many children spend an unlimited amount of time on the Internet

My kids rarely use computers, but they spend a lot of time with their smartphones. So I decided to install Hoverwatch is a phone tracker https://www.hoverwatch.com/ which makes it easy to find phone, lets you record calls and access not only text messages but all types of media use on smartphone.

Agree. It is a really difficult task. But I have found a couple of ideas to resolve this problem. I offer my Bunny to play and to see the results of her activities. My surprise was great, as she didn't only start to play with it, but she forgot about the computer for a week!
