What we do

We build calculators for everyday health and fitness questions: BMI, calorie needs, macros, sleep timing, due dates and more. Each page pairs the working tool with plain-language explanations, reference tables and answers to common questions.

What we stand for

• Transparency. We name the formula and source behind each result and show the arithmetic.
• Safety. Calorie and weight tools apply conservative limits and point you to a doctor or dietitian when inputs look extreme.
• Privacy. Calculations run in your browser. We do not ask for an account and we do not receive the numbers you type in.
• Honesty about limits. A calculator gives an estimate from a few inputs. We say what each one cannot tell you.

What we are not

HealthFitnessHQ is not a medical practice, and nothing here is medical advice, diagnosis or treatment. We cannot answer personal health questions. If you are worried about your health, speak with a doctor or another qualified professional. In an emergency, contact your local emergency number.
