About Macrolyze
Understand. Not just count. Macrolyze helps you understand how nutrition and behavior affect your body — data-driven, visual, and built for everyday life.

Effortless tracking Log food by photo, voice, or visual search. Macrolyze automatically recognizes foods and analyzes nutrients, ingredients, and context. Patterns, not snapshots Macrolyze connects nutrition, behavior, and daily responses into clear insights — so you can see relationships and make informed decisions. From data to insight See not just what you eat, but how it affects you — across days, weeks, and habits. Macrolyze — understand your nutrition.
