Which of your own numbers can you believe?

A body-composition printout states more numbers than it measures. Most are estimates derived from two or three real readings — and they do not always agree with each other. Type yours in and we recompute every relationship, showing the arithmetic.

Sixteen numbers is a lot to type. If your report is a PDF, this reads it and fills the form for you — in this tab, on your machine. Nothing is uploaded. You still confirm every field before anything is checked.
