BMI3D calculates the Body Mass Index (BMI) and displays it with human 3D models. Since the BMI makes no statement about the body fat percentage, a corresponding fat calculation is integrated. This is based on measured values of approx. 6000 people.

In the before/after view, a desired body fat reduction can be anticipated. The app shows the desired BMI, body fat percentage and also changed body measurements after a corresponding weight loss.

For an exact body fat calculation only waist, hip and neck circumference are needed. These values are taken easily with a measuring tape. The Pro version uses this data to calculate your exact and precise body fat.

You can order the Pro version with In-App-Purchase. The subscription period is one week. It renews unless auto-renew is turned off at last 24-hours before the end of the current period. Your account will be charged for renewal withing 24-hours prior to the end of the current period, and identify the cost of the renewal. After purchase you can manage subscriptions in your account and turn off auto-renewal. Any unused portion of a free trial period, if offered, will be forfeited when you purchases a subscription, where applicable.

The prices can vary based on your country and currency. The Pro version is a recuring subscription with cost. It is handled at the App Store on your device.

Does not calculate correctly

This has a website that seems accurate. I have been disappointed because the iPhone app is grossly inaccurate. My BMI is about 31 but it lists me as being above 60. I’ve carefully gone back through the steps several times to ensure I’m using correct units, converting correctly (it strangely has you measure your waist circumference, etc in feet and inches rather than just inches). The graphical figure it generates seems reasonably accurate (compared to looking in the mirror) but the calculations are completely off. The website seems not to have this issue but the iPhone app needs revision.

Sadly disappointed

Aside from the measurements not working, I paid for the pro version a long time ago.
There was issues even back then but I contacted their support and it was fixed in a couple days which was why I ended up paying for the pro version.
Very disappointed that after I updated the app I no longer have the pro version.
The salt in the wound was when I saw that if I want my pro version back it would cost me 99 cents a week.
I don’t need this app that bad. There are many apps for measuring BMI.

All of It

It is so inaccurate especially because it doesn’t let you choose the specifics of your character such as neck size, hip size, etc. As such, it doesn’t even look right. It depicts being fat with a high BMI, which is sometimes wrong, as we see with muscular individuals. And it has a narrow set of limits. Such as where you can’t even go under 18 or over 30 on the BMI. I recorded my height as 5’7” but the weight can’t get under 55 kg, as if people can’t be under this.
