Help us build the future of accessible health intelligence.
Help us improve the health of every human being — at near zero cost.
NutriSize is a health intelligence app that provides science-backed nutrition and exercise guidance referencing WHO, ACSM, and NASEM standards. It is built and maintained by a single developer who believes that access to quality health information should not depend on income or background.
Every feature is designed with privacy at its core — your health data stays on your device. NutriSize is available on iOS, Android, and Web, and all essential features are free. Your support helps us continue improving the app, adding new features, and reaching more people around the world.
Modern healthcare too often operates as sick care rather than true preventive health care. Not every illness can be cured, especially when new threats emerge unexpectedly. The COVID-19 pandemic made this starkly clear: in the absence of early vaccines, those who fared best relied on the strength of their own natural immunity.
The most reliable, long-term way to cultivate and sustain robust immunity is through consistent, high-quality nutrition combined with regular physical activity. Nutrisize gives you efficient, practical tools to optimize both, helping you build resilience and better prepare your body for whatever health challenges may come next.
All core features of Nutrisize remain completely free forever, with no essential functionality locked behind paywalls. This app exists because I chose to donate my time, expertise, and labor for the betterment of humanity without charging for the foundation of the product.
If you find Nutrisize valuable and would like to support its continued development, improvement, and free availability for everyone, you are warmly invited to donate yours as well. Easy, secure donation options are built directly into the app via PayPal and other methods, and every contribution, large or small, is deeply appreciated. Thank you for choosing to invest in your health and resilience. Together we can build a stronger, healthier future.
