This APP requires no effort to use. It is truly self explanatory! Enter 3 data points Height in Feet and Inches followed by entering your Weight and press the Calculate button and you receive your result. One potential improvement could be, if the large section would display the same color as the BMI number and the BMI numerals could be displayed white or blackas a choice of the individual. Thank you William

I read the reviews that pleaded for decimal points and downloaded the app, anyway. Now that I have trird it, I see how important the decimal is. The app is small, easy to use, and has a lot of useful info in one place. But, I'm going back to the website.

Very simple BMI calculator. It could be improved by remembering height as that usually does not change as often as your weight. Just remember that the BMI is not a very reliable indicator for a problem.

This app is great, it's simple and easy to use. The only drawback is that you can't use a decimal point for weight measurements.

I don't see how someone could rate it less, it's a calculator and it calculates well, that's all, perfect.

Good app in theory, but as many other users have stated the inability to use decimals makes it inaccurate and thus, useless. It cannot do its one job because of this mass oversight. How can you not allow decimal points???

Calculates close to what the website had, but you can't include decimals in pounds. I'll stick to using the website.

I prefer a decimal point be added for any use for myself being for half inches and tenths of lbs in digital weight.

This app is good if you live in the United States. If you are elsewhere, then it could be very frustrating; and it should be avoided.

Simple to use, but not allowing a decimal place for weight in kg is not good enough.

Can't use it, doesn't support metric properly. Unlike the imperial system metric uses decimals...

For those of you trying to find this app, it's called "MY BMI CALCULATOR". I just saved 10 minutes of your lives.

Love this app

Totally useless. Put in height and weight, tells me I'm underweight and to ask my Dr if this is a healthy weight for me. Any online calculator could tell me this without taking up space on my phone

A. G. u. Jul 7, 2017

Does not allow decimal points... Only whole inches and whole pounds so not accurate enough. Should allow weight to at least nearest half inch and tenth of a pound.
