BMI Calculator: Ideal Weight S

Calculate your BMI instantly, track your trend over time, unlock Body Metrics, daily challenges, streaks, and Apple Health sync, all private, no account needed.

CALCULATE YOUR BMI INSTANTLY Enter your height and weight to see your BMI, category, and a clear healthy-weight range in seconds. Choose WHO or DGE classification, switch between metric, imperial, or stone units, and get a dedicated result for kids and teens.

TRACK YOUR PROGRESS Every calculation is saved to your personal history. Watch your trend on a simple chart, set a goal weight, and see your start, current, goal, and average all in one place.

KNOW YOUR NUMBERS Go beyond BMI with Body Metrics: BMR and daily calorie needs (TDEE), body fat percentage, and waist-to-hip ratio with a clear risk level, all from the same measurements you already entered.

BUILD A DAILY HABIT A simple daily challenge keeps you checking in water, walking, sleep, mindful eating with streaks that reward consistency, not perfection.
