Krestrel

Diet and care tracking for children with metabolic conditions.

A private record-keeping app for parents and legal guardians: meals and nutrients, growth, labs, medications, and daily care. No ads, no third-party tracking.

Krestrel is a tracking tool, not medical advice. It does not recommend diets, restrictions, or amounts. Nutrient figures are reference values from USDA FoodData Central and may not match specific products — always confirm values and your child's dietary plan with your metabolic dietitian and care team.

This site hosts the legal and support resources for the Krestrel mobile app. Everything here is written for the people who use the app: parents and legal guardians tracking their own child's care.
