We have created ScreenCoach with school work in mind. If your child has a locked-down school owned device, you may not be able to install ScreenCoach.  However, if you have access to install Apps on your child's device, you should be able to install ScreenCoach. You can even have a mode called "School time", where all the non-educational apps are blocked to ensure your child focuses on their school work. This is also perfect for home schooling parents!
