Screen Time for Mac
According to report from 9to5mac, Apple is going to introduce ScreenTime for macOS. Most likely using Marzipan (their new framework that allows to port iOS apps for MacOS). This app is needed to make your screen time monitorable everywhere. When you see how you spend your time you start to appreciate it, than in the case when you have no opportunity to compare how much time you spent on work and games last week. It will allow us to develop ourselves by adding limits for apps and to control our children screen time.
My concept went further — you can see the time you spent on other platforms in the form of summary and compare it. You can monitor your time even easily by adding Screen Time to Menu Bar and give yourself opportunity to check spent screen time today and limits left.
