In 2024, while researching emerging digital market trends, I discovered a critical gap in the health sector: platforms like MDCalc—used by 65% of US physicians—don't have Spanish versions, leaving millions of people in Latin America without access to reliable medical tools.

The analysis revealed that searches like 'BMI calculator,' 'calorie calculator,' and 'due date calculator' generate hundreds of thousands of monthly queries in Spanish, but available options are limited, outdated, or monetize users' personal data.

As a developer committed to digital accessibility, I saw an opportunity to create something different: a platform that combines medical precision with complete privacy. HealthCalc was born with a clear mission: to offer free, accurate, and privacy-respecting health calculators, without storing personal data or requiring registration.

Each calculator uses internationally recognized medical formulas, all processing happens locally in your browser, and access is completely free. Because basic health tools shouldn't be a privilege, but an accessible right for everyone.
