Guia Nutri is an Android application developed by Domore Web e Software, with the intention of providing easy access to food composition data for those interested in nutrition, students or health professionals. The app provides basic information on food composition, nutritional education, quality control and safety, nutrient intake assessment, and adaptation for individuals or populations.

The application is user-friendly and allows easy access to information on minerals, vitamins, proteins, calories, cholesterol, and more. It also enables users to calculate the food characteristics based on the desired portion size in grams. Currently, the app uses data from the Brazilian Table of Food Composition (TACO) developed by the Center for Studies and Research in Food (NEPA).

New data sources will be available in future versions. The app is open to suggestions, criticisms, and compliments to improve and enhance the user experience.
