Mathematically BMI is a person’s weight in kilograms divided by the square of height in meters. BMI is moderately correlated with more direct measures of body fat and is often times used as an estimate for overall body fatness. BMI only uses weight and height, and then compares it to an average scale. An athlete would operate outside the standard curve, since muscle mass would give them additional weight without adding body fat. This app uses a single scale for both Men and Women. To determine if your BMI is a health risk, a healthcare provider would need to perform further assessments.

They kept it simple and easy to use. Use this one if you're interested in tracking BMI. Graphs are a nice touch.

$$ Grabber

It is highly limited. And inaccurate because of it. AND every time you run it, it converts to a bariatric ad that fills the screen. And it’s not even specific. I entered weight wrong and was shown highly underBMI, and it still told me bariatric surgery was perfect for me!
I deleted it. I can easily get the same measurement in a FREE app ONLINE with a simple google or bing search. No need to pay for an on-device app, especially if it doesn’t do it right.

If you don’t pay to remove them, you get annoying ads obscuring the screen. You also have to pay to track more than 2 BMI scores over time. And it doesn’t include age in the calculation. Ended up deleting it.
