I want to build an extremely basic app to help my son manage his diabetes. There are many apps available. But they are all too involved. He needs super basic. So I decided to make him an app. I’m struggling with figuring out one piece. I’ve created a “settings” page where he can input certain information. That information will need to be saved for use in calculations on another page. I made a save button and created the variables for that button. But I can’t figure out how to make the information that the user inputs save for use on another page. I have zero experience. I’m just a mom trying to help my son. Can anyone help me?
