詳細資訊
metaXring Arc listens to your heart rate, HRV, blood oxygen, skin temperature and sleep, all day and all night. It measures every reading against your own 30-day baseline, turns them into one number — Body Power — and the app tells you in plain words what changed and what to do next. No screen, nothing to check: just a ring you forget you're wearing.
