Tape measurements — waist, chest, arms, and the rest — tracked separately from your scale weight, one site at a time.
Current measurements lists the latest reading for every site you've logged at least once — nothing shows until you log your first one. Below that, Log a measurement records a new reading for the site you pick, in your length unit, on any date. Choosing a site loads its trend chart and full history at the bottom of the page.
Measurements sync the same way your other data does, but they don't mirror to Health Connect — that's bodyweight only (see "Bodyweight log"). Delete a bad entry with the ✕ next to it in the history list; you're asked to confirm before it's gone for good.
