Smart Scales for Multiple Users: RENPHO Elis 1 vs Etekcity ESF-551

Compare RENPHO Elis 1 and Etekcity ESF-551 for household use: separate accounts, shared profiles, app syncing, capacity and weight-only controls.

Direct answer

For households, the key distinction is privacy: separate app accounts keep each person's trend data apart, while profiles under one shared account are easier to manage but may expose measurements to other account users.

Quick answers

Frequently asked questions

Can several people use one smart scale?

Yes, but account limits and privacy differ. Verify whether each person can use a separate account or must share profiles in one account.

Will a smart scale recognize users automatically?

Some apps match measurements to likely profiles by weight history. Similar-weight users may still need to confirm the correct profile.

Are body-fat readings medically accurate?

No consumer smart scale should be treated as a diagnostic device. Hydration, meals, exercise and foot contact can change impedance estimates.
