About this tool
This tracker keeps a dated series for weight, waist, chest, hips, arms, thighs and neck, plots any metric as a line chart with a least-squares trendline, and reports the change since the first and previous entries. It derives BMI, waist-to-height and waist-to-hip ratios with their published bands, and the US Navy tape-based body-fat estimate when the required measurements are present. These are screening calculations, not a medical assessment — tape measurements are only as good as your technique, and no result here is a diagnosis. Your entries stay in your browser's localStorage with JSON import/export and a CSV download; nothing is uploaded.
