Design implementation is completely done, just need functionality to work. I am creating a mobile app that facilitates nutrion challenges in groups both public and private groups that users can create. The users will recieve points for reachy daily nutrition goals concerning macros(amount of protein, carbs, and fats). Each person macro counts is different, so the system will have to calculate those numbers from inputs from the user and a table that I will provide. Obviously, main goal is for the user to receive the most points within the group between a start date and end date.
