I wanted something like the old Richard Simmon's Deal a Meal cards to use. My ideal app would allow me to Choose my calorie needs for the day, figure protein, carb & fats, divide them into servings (by default and by my own choosing) of food groups, and have an easy to see screen divided into groups. I want to include how to figure number of grams for each of protein, carbs, fats as calculated by percentages, so I can vary my intake, say, of protein from 30% to 25% or whatever, same with carbs & fats.
