Love it but one issue

This app is so great and easy to understand. It’s very fast and gives an accurate BMI number. However, the accuracy of the underweight/overweight placing is off. An underweight BMI, is anything less than 18.5. This app says that to be “underweight” you need to have a 15.6 BMI. 15.6 is severely underweight. Same thing with the overweight. Having a BMI over 21, is not overweight, but the app says it is. So, great app, great numbers, but just remember, 18.5 or under is underweight, and over 25 is overweight. Don’t be tricked into thinking you are overweight✨

Here’s why there’s so many bad reviews:

To make it fast: recently there’s been a push to get rid of and ‘cancel’ any sort of apps that “promote Diet culture and fatphobia”. People don’t like apps like this bc it deals with weight loss and health, and it seems like anything that tells a person that they are fat and overweight is somehow bad now. The app is accurate, and if any of the reviews actually cares about that they could’ve done the research I did to make sure it was accurate. But they don’t. They just don’t want people to take care of their healthy and know their BMI.

So inaccurate

This app is super inaccurate. Let's say I was 5 feet and 100 pounds. You are told that you're a "normal" weight, but it's underweight, according to most of the other apps i've tried out. This app is lying to you, remember, you are beautiful and fantastic the way you are. If perfect were a thing, that'd be you. Your body size doesn't describe what kind of person you are. Don't go into thinking your a under, or over weight.
