About Health & Fitness
Health calculators give you a clear picture of your body metrics, nutritional needs, and fitness targets. Instead of guessing, you get data-driven insights based on your age, weight, height, and activity level.
Softzar offers a full range of health and fitness tools. Calculate your BMI, estimate daily calorie needs, find your ideal weight range, determine your macros, track your sleep cycles, and more. Each tool is built around established medical formulas and guidelines so you can trust the numbers.
All health data stays in your browser. Your personal measurements are never uploaded or saved.
How to Use Health & Fitness
Select the health or fitness calculator relevant to your goal. Fill in your personal measurements — these are used only for the calculation and never stored. Review your results and use them as a reference for your health and fitness planning.
Frequently Asked Questions
Are these calculators medically accurate?
The calculators follow widely accepted medical formulas. BMI uses the standard formula from the WHO. Calorie needs are based on the Mifflin-St Jeor equation. BMR uses the Harris-Benedict equation. These are referenced by healthcare professionals for initial assessments.
Should I use these results to make health decisions?
Use the results as a helpful reference point, not a medical diagnosis. Always consult a doctor, dietitian, or healthcare provider before making significant changes to your diet, exercise, or lifestyle.
How is BMI different from body fat percentage?
BMI estimates body fat based on height and weight alone. Body fat percentage directly measures how much of your weight is fat versus muscle and bone. Two people with the same BMI can have very different body fat percentages, especially athletes.
