Calculate Body Mass Index (BMI) to assess weight status and health risk with accurate BMI categorization. Uses standard BMI formula (weight/height²), categorizes results as underweight, normal, overweight, or obese, supports metric and imperial units, and provides health risk assessments. Essential for health screening, weight management, and fitness goal tracking.
View BMI ranges and classifications specifically for women with comprehensive height and weight reference tables. Shows weight ranges for each BMI category (underweight, normal, overweight, obese) across different heights, helps women understand healthy weight ranges, and provides guidance for weight management goals. Essential for women's health planning and fitness tracking.
Calculate daily calorie needs for weight loss, maintenance, or weight gain using BMR and activity level calculations. Uses Harris-Benedict or Mifflin-St Jeor formulas, accounts for activity levels (sedentary to extra active), creates calorie deficits for weight loss or surpluses for weight gain, and helps plan sustainable nutrition goals. Essential for diet planning and fitness tracking.
Calculate body fat percentage using various measurement methods including Navy method, Deurenberg formula, and body circumference measurements. Requires waist, neck, and hip measurements, provides gender-specific calculations, categorizes results by fitness level, and helps track body composition changes. Essential for fitness goals focusing on fat loss and muscle gain.
Calculate Basal Metabolic Rate - calories your body burns at rest to maintain basic bodily functions. Uses Mifflin-St Jeor or Harris-Benedict formulas, accounts for age, gender, height, and weight, represents 60-75% of total daily calorie burn, and serves as the foundation for calculating total daily calorie needs. Essential for accurate calorie and nutrition planning.
Calculate your ideal body weight range based on height, gender, and body frame size using Robinson, Miller, or Devine formulas. Accounts for small, medium, and large frame sizes determined by wrist circumference, provides weight ranges rather than single numbers, and correlates with healthy BMI ranges. Essential for setting realistic weight management goals.
Calculate running pace, speed, and time for distance running and training with comprehensive pace analysis. Converts between pace (minutes per mile/km) and speed (mph/kmh), calculates target paces for race goals, estimates finish times for different distances, and helps plan training runs at various intensities. Essential for runners training for races and tracking performance improvements.
Calculate optimal sleep and wake times based on sleep cycles for better rest and easier waking. Accounts for 90-minute sleep cycles, suggests wake times at cycle completion points, helps plan bedtimes for specific wake times, and optimizes sleep quality by avoiding mid-cycle awakenings. Essential for improving sleep quality and morning alertness.
