Eufy Smart Scale P3
The P3 suits someone who wants to choose which readings appear on the scale itself. Its detailed body-composition estimates are best used for longer-term trends.
Benefits & things to consider
Consider it for
People who want a configurable on-scale display
Main compromise
More metrics do not make every reading clinically precise.
Before buying
Check EufyLife compatibility and the T9150 model number, rather than assuming all Eufy scales share the same display.

Garmin Index S2 Smart Scale
Keep weight records alongside activity data in Garmin Connect. Its strongest reason to choose it is the existing Garmin ecosystem, rather than a promise of more accurate body-fat readings.
Benefits & things to consider
Consider it for
Existing Garmin Connect users
Main compromise
Less compelling if you do not already use Garmin's app.
Before buying
Set up through Garmin Connect and check your home Wi-Fi connection before relying on automatic syncing.

We checked the exact model descriptions and published specifications, compared each choice’s practical role and reviewed relevant alternatives. We retained products where a newer name alone did not justify a change.
Our recommendations are editorial judgements based on those published differences. We have not measured performance, comfort or long-term durability. A manufacturer listing confirms a reference model, not current Amazon stock.

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.
Buying check 1
Choose a scale around the app you will actually use. Body Smart includes core measurements and trends without a Withings+ subscription; Garmin Index S2 is most useful if you already use Garmin Connect. Body-composition figures are estimates, so compare trends measured under similar conditions rather than treating a daily change as a precise measurement of fat or muscle.
