BMI Calculator — BMI Level

Work out your BMI in seconds, then keep track of how it changes.

BMI Calculator turns two numbers — your height and your weight — into a clear answer: your Body Mass Index, which category it falls in, and what a healthy weight for your height would be. No account, no sign-up, no waiting.

WHAT YOU GET

• Instant results
Enter your height and weight and see your BMI straight away, shown on a clear dial with your category highlighted.

• Both unit systems
Feet and inches or centimetres. Kilograms or pounds. Switch at any time — your measurement is kept, not wiped.

• Every result saved
Each calculation is stored automatically with the date, so you can look back at any point.

• Progress over time
A chart plots your BMI across your saved calculations against the healthy range, so you can see the direction you are heading rather than a single number in isolation. It also shows what changed since your last result and since you started.

• Understand the numbers
A dedicated screen explains every BMI category — underweight, normal, overweight and obesity — what each range means and where your own result sits.

• Your healthy weight range
Along with your BMI, the app shows the weight range considered healthy for your height, so you have something concrete to work with.

• Five languages
English, Hindi, Spanish, French and German. The app can follow your device language or you can pick one.

• Light and dark themes
Follow your system setting, or choose light or dark yourself.

• Works offline
Everything is calculated on your phone. Your height, weight and history stay on your device — they are never uploaded.

BUILT TO STAY OUT OF THE WAY

The app is free, supported by ads that are kept away from the things you came to do — never over your result, never between you and the answer. Prefer a break from them? Watch one short video and the app goes ad-free for 24 hours.

ABOUT BMI

Body Mass Index is a simple screening measure that compares your weight to your height. It is widely used because it is quick and needs no equipment, but it is only one indicator. It does not measure body fat directly and does not account for muscle mass, bone density, age, sex or body composition, so a very muscular person may get a high reading while being perfectly healthy.

The adult categories used in this app follow the World Health Organization's standard ranges. They are intended for adults aged 20 and over, and are not suitable for children, teenagers, or people who are pregnant.

This app is for general information and is not a medical device. It does not diagnose, treat or prevent any condition, and nothing it shows is medical advice. Always talk to a doctor or qualified health professional about your weight, your health, and before making changes to your diet or exercise.
