Frequently Asked Questions
How accurate are your health calculators?
Our calculators use scientifically validated formulas with accuracy rates of ±10% for most individuals.
The Mifflin St. Jeor formula (our default for BMR) is considered the most accurate for the general population.
However, individual results may vary based on personal health factors.
Do you store my personal health data?
No, we do not store any personal health information. All calculations are performed client-side in your browser,
and your data never leaves your device. We only collect anonymous usage statistics to improve our services.
Can I use your calculators for medical decisions?
Our calculators are educational tools only and should never replace professional medical advice.
Always consult with qualified healthcare professionals for medical decisions, especially if you have
health conditions or are planning significant lifestyle changes.
How often do you update your formulas?
We regularly review and update our algorithms based on the latest scientific research and user feedback.
Major updates are typically implemented quarterly, with minor improvements made continuously.
Is there a mobile app available?
Currently, we offer a fully responsive web application that works great on mobile devices.
You can add our site to your home screen for an app-like experience. Native mobile apps may be
considered for future development based on user demand.
