- MacroCodex is a maintenance calorie tracking app that adapts targets based on real intake and weight data, unlike static TDEE calculators which rely on population-average formulas and can be inaccurate.
- The app helps users choose between cutting, bulking, or recomposition phases, provides weekly metrics to track progress, and offers trend views to reduce stress from daily weight fluctuations.
- It takes about 3-4 weeks of data to accurately estimate maintenance calories, using initial formulas like Katch-McArdle and then refining with actual user data.
- MacroCodex integrates via Google Health Connect with apps like MyFitnessPal or Cronometer for calorie logging, as it focuses solely on maintenance tracking without built-in food tracking.
- The app is free when paired with free calorie trackers, unlike paid alternatives like MacroFactor, and supports custom macro splits for diets such as keto.
- Users are advised to log intake at least 7 out of 10 days for reliability and can manually input maintenance calories during onboarding if desired.
- For body fat estimates, DEXA scans or methods like the US Navy formula are recommended over smart scales or wearables due to accuracy concerns.
