Eufy Smart Scale P3
Eufy Smart Scale P3 advertises sixteen metrics. Consider whether those readouts are useful to you; their number does not establish accuracy or make them a medical assessment.

You prefer Eufy’s app presentation and will use its trend history.
Main compromise
More displayed metrics can add information you do not need.
Before ordering
Review the app, account requirements and model T9150 before buying.

It is less compelling if you do not want another Garmin account or app routine.

How to choose bathroom scales
Which app do you want to keep using?
Look at the app before choosing the scale. Consider whether you can easily find the history you care about, which features require an account and whether any optional services have charges. If you only want a weight readout, ask whether you need a connected model at all.
Plan household profiles and privacy
Check how each person creates an account and how readings are assigned. Do not assume every metric is visible to every household member, or that privacy settings are identical across brands. Read the current account and data-sharing controls before linking another service.
What can this comparison say about accuracy?
We have not tested these scales against reference equipment. Body-composition readouts are estimates and should not be treated as a diagnosis. Follow the exact manual for positioning, measurement conditions and any restrictions on using its body-composition functions; compare trends cautiously rather than treating one reading as a verdict.
