About this app

Easy to use and free BMI Calculator App (no ads). The Body Mass Index (BMI) is calculated with the standard formula also used by WHO.

Please note that age and gender DO NOT affect BMI calculation.


What is BMI?

Body mass index or BMI, is used to determine whether you are in an ideal weight range for your height.

It gives you an idea of whether you’re "underweight", a "healthy weight", "overweight", or "obese" for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease. 

BMI is a useful measurement for most people over 20 years. It is an estimate and should be considered as a rough guide only as it does not take into account age, gender, ethnicity or body composition.

BMI Calculator formula options

✅ Standard BMI formula:
For nearly 200 years now, medical professionals the world over have used the universally accepted Body Mass Index (BMI) to help assess the overall state of a person’s health.

✅ New BMI formula:
Experts have identified a flaw in the basic BMI formula and have recently come up with a new calculation which presents a more realistic result as it scales more accurately in relation to a person’s height.


BMI Calculator classification

💙 BMI of < 18.5
A BMI of less than 18.5 indicates that you are underweight, so you may need to put on some weight. You are recommended to ask your doctor or a dietitian for advice.

💚 BMI of 18.5–24.9
A BMI of 18.5–24.9 indicates that you are at a healthy weight for your height. By maintaining a healthy weight, you lower your risk of developing serious health problems.

🧡 BMI of 25–29.9
A BMI of 25–29.9 indicates that you are slightly overweight. You may be advised to lose some weight for health reasons. You are recommended to talk to your doctor or a dietitian for advice.

❤️ BMI of > 30
A BMI of over 30 indicates that you are heavily overweight. Your health may be at risk if you do not lose weight. You are recommended to talk to your doctor or a dietitian for advice.

More information about Body Mass Index classification which is used by our BMI Calculator App is available on the website of the World Health Organization (WHO).

Its a great app to measure BMI with new and old formulas. What i found difficult is the unit changing I want to add weight in kilograms and add height in ft and inches. But on selecting either they change both units. Kindly adjust the functionality just that units are free of systems. Not metric or others.

Easy and fast to use with a great design. No ads, no costs and nearly no storage used. Definitely the best BMI calculator out there. I recommend to also take a look at the other apps of the developer because I'm very happy with their drink reminder app "Hydro Coach" too.
