MacroCodex

MacroCodex is a calorie tracking app that calculates maintenance calories (TDEE) from user weight and calorie intake data, solving the problem of weight loss or gain stalling due to metabolic adaptation. It targets individuals focused on fat loss, body recomp, or lean bulk, including consumers and data-oriented users. The app differentiates by using a dynamic algorithm that adapts to real data over time, unlike static calculators, and offers a free, ad-free, subscription-free service with no personal data collection.
