Hello, nice to meet you, I am a novice programmer. Some time ago as a school project I made an ecological calculator as a mobile application, which was obviously an alpha version, now for a better presentation I would like to create a more complete app.
I would like to make it have an interface similar to the applications of exercise routines to lose weight, let me explain, I want to create an interface in which you can see your progress on a weekly basis.
My calculator sends a message in which it says if your ecological footprint is sustainable, abnormal or disastrous when answering a questionnaire, in this questionnaire points are added the more harmful your consumption is and in the end it yields the result. I want the result to be saved so that the following week it will be shown if you improved or worsened in your consumption. I hope you can help me understand how to do this, please.
