"Nutrition Optimizer" (AKA "macros.cheap") is a timely math macronutrient cost optimizer, based on the cost of food at the Aldi chain. Macronutrients are different categories of food such as protein, carbs, and fat. This app will be especially handy after everybody is poor from all the tariffs. The generated diet is pretty basic and I'm not sure that many people would want to do it on a long term basis.
