Frequently Asked Questions
What health calculators are available?
We offer free health calculators including BMI calculator, BMR calculator, calorie calculator, body fat calculator, and water intake calculator. These tools help you understand your health metrics and set fitness goals.
How accurate are these health calculators?
Our calculators use standard medical formulas used by health professionals worldwide. However, they provide estimates and should not replace professional medical advice. Always consult a healthcare provider for personalized guidance.
Is my health data kept private?
Yes, absolutely. All calculations happen locally in your browser. Your height, weight, age, and other health information is never sent to or stored on any server. Your privacy is fully protected.
Can I use BMI as my only health indicator?
BMI is a useful screening tool but has limitations. It does not distinguish between muscle and fat, and may not be accurate for athletes or elderly individuals. Use it alongside other health metrics and professional assessments.
How often should I recalculate my health metrics?
For general health monitoring, monthly calculations are sufficient. If you are actively working on fitness goals, weekly or bi-weekly checks can help track progress. BMR may only need recalculating when your weight or activity level changes significantly.
