Frequently asked questions
- How accurate are smart scale body fat readings?
- Bioelectrical impedance estimates are approximate and affected by hydration and time of day. They are most useful for tracking trends over time rather than exact figures.
- Do smart scales need Wi-Fi?
- Some scales sync over Wi-Fi for automatic uploads, while others use Bluetooth and require your phone nearby. Choose based on how hands-off you want syncing to be.
- Can multiple people use one smart scale?
- Most smart scales support several user profiles and recognise individuals by weight, keeping each person's data separate within the companion app.
