❓ Frequently Asked Questions

What makes your BMI calculator unique? +

Our BMI calculator shows not just your BMI, but also your visceral fat risk level, compares your BMI to others in your age group through an interactive graph, and adjusts for ethnicity (Asian, Caucasian, African) for more accurate health assessment.

How does the gut microbiome score work? +

Based on research from the American Gut Project and Harvard, it analyzes your fiber intake, probiotic foods, antibiotic history, and digestive symptoms to give you a science-based gut health score.

What is the circadian rhythm optimizer? +

It uses the validated Morningness-Eveningness Questionnaire (MEQ) to determine your chronotype (lion, bear, wolf, dolphin) and provides a personalized daily schedule for optimal sleep, energy, and productivity.

How accurate is the heart risk calculator? +

We use the Framingham Risk Score and ASCVD algorithms, which are medical-grade and used by physicians. It shows your 10-year risk of heart attack or stroke and your heart age.

What is the inflammation score? +

Based on the Dietary Inflammatory Index, it calculates your inflammatory load from diet, lifestyle, and symptoms. It estimates your CRP levels and gives anti-inflammatory recommendations.

How does the vascular age calculator work? +

Using Framingham Heart Study data, it estimates your arterial stiffness and vascular age based on blood pressure, lifestyle factors, and demographics. Vascular age is a stronger predictor of heart attack risk than chronological age.

Are these calculators really free? +

Yes! 100% free forever. No signup, no credit card, no hidden fees. All calculations happen in your browser - we never store your personal data.

Can I use these on mobile? +

Absolutely! All our tools are fully responsive and work perfectly on phones, tablets, and desktops. The interface automatically adjusts to your screen size.
