What people say
Real reviews from Google Play, quoted exactly as written. Each one links to itself on the listing so you can check it.
Very easy to navigate and use. The accuracy is far superior to any other BMR/TDEE calculators I've seen. Great job to the developers!

What a cool body calculator. It is very simple in use and works perfectly well. Recommend.
Excellent BMI app with so many other informative tools
What you get that the website cannot give you
Every calculator on this site works in your browser and always will. The app adds the parts that need to remember you: past readings so it can tell you what changed, more than one person on the same phone, and the child growth check against the WHO curves.
If it is tracking over months that you actually want, rather than a number today,read the comparison first. One of the other two apps may suit you better, and installing the wrong one is nobody's idea of a good time.
This is not medical advice. Body Numbers is a calculator. It does not diagnose, treat or monitor any condition, and no number it produces should replace a conversation with a doctor or a dietitian. If a result worries you, or if you are pregnant, unwell, or under eighteen, speak to a health professional.
