Track tape-measure body measurements alongside weight and protocols: waist, hips, chest, arms, thighs, neck, calves, shoulders, with room for additional sites later. Manual entry with trend charts over time, shown alongside your compounds so changes can be correlated with what you're taking. Especially useful where the scale alone tells an incomplete story: GLP-1 users watching inches move before pounds, and TRT/bodybuilding users tracking growth. Could later sync from Apple Health / Health Connect, which both support waist circumference and related measurement types.
