Terrible app! The app is built into your router. my child is studying remotely. I know that it is possible through a router to restrict a child's access to a site or page, but you can also add approval to the page and sites from one or more. AT and T put this damn app in your router settings and at the step of when you would like to adjust the access or restriction. the number of devices you will get out this app. and it has only one function to completely cut off the Internet at a given IP addr
