The iNuba index is generated taking into account your body composition, gender, height, and goal. To activate it you must go to the 3D Human section in the app and at the top you must select “Complete your manual measurements to access your iNuba index”. In the basic metrics section, you will need to enter your “waist” and “hip” perimeters and hit the update button. When you return to the 3D Human tab you will get the index and a score from 1 to 10. Scrolling down you will get tips related to your index, lifestyle and goal.
