Why are my body composition numbers different from the ones I see at my gym, doctor, etc.?

Body composition analysis is an inexact science, regardless of the manufacturer or method of measurement. Because your scale combines the measurements it takes with variables stored in your user profile according to our algorithm, the numbers you see may vary from those you see using other measurement methods – which is completely normal. When you're measuring body composition, it's more important to pay attention to overall trends than the absolute value of a single measurement. (Tracking in the Renpho app helps with that.)
