Google's Family Link allows very granular control over what your kids do with their devices. The the extend that you get a notification if you want for every app they try to install and won't get installed unless you permit it. You can set time limits not just for screen time but on on a per app basis as well. I don't know how this works but from my experience I found that Google's got this one right.
