- Weight: use the scale on the same hard floor and at a similar time.
- Trend: look at weeks and months, not isolated day-to-day changes.
- Body composition: treat body-fat and muscle readings as approximate trends, never a diagnosis.
- Privacy: review permissions, account deletion and integrations before syncing data.
- Clinical use: medical decisions require professional assessment and appropriate methods.
One consistent, simple measurement is more useful than a long list of unstable numbers.
Safety: People with implanted medical devices and pregnant users should follow manufacturer instructions and ask a clinician before using bioimpedance features.
