Hello! I have to do a class project, which the function of the app is to be able to block any installed mobile app for a limited period of time, I have been researching all the sites (forums, web pages, etc.) but the result has I have been a failure, because nowhere have I been able to see anything similar, that's why I write these two questions:
Is it possible that the "effect" of an inventor app function can be active even if the application is closed?
Is it possible to make an application which can block for a certain time?
Any kind of guidance or help will help me a lot.
