The best smart scale depends on what you want to track: reliable weight history, estimated body composition, or extra heart-related features. For straightforward weight and composition tracking, consider the Withings Body Smart. The premium Withings Body Scan 2 adds higher-tier features, while the Garmin Index S2 makes most sense for people already using Garmin Connect. The Eufy Smart Scale P2 Pro is another feature-rich option. Treat body-fat and other body-composition numbers as estimates—not clinical measurements—and do not treat a scale’s heart-related readings as a diagnosis.
How to choose a smart scale
Start with the information you will actually use, then check whether the scale works with the app ecosystem you already use. A scale that records weight consistently may be a better fit than one with more readings that you will not use or cannot interpret.

- For weight history: prioritize easy-to-read trends and dependable app syncing.
- For body-composition estimates: look for the particular measurements you want, but remember that they are derived estimates rather than direct readings of body fat.
- For extra heart-related features: check the exact feature list and its availability in your country. A feature listing does not establish a diagnosis or replace medical care.
- For app fit: check whether the scale works with the service you already use, such as Withings or Garmin Connect.
- Before buying: confirm current local availability, price, feature access, and any subscription terms. These can change by model, region, and date.
Smart scale recommendations
Withings Body Smart: a simpler weight-and-composition option
The Body Smart is a reasonable starting point if you want weight and body-composition tracking without choosing the brand’s highest-feature tier. Withings lists weight and composition data across several of its scale models, with app syncing across its scale range. See the Withings scale range and its model feature comparison for the current feature list.

Withings Body Scan 2: a premium feature tier
Withings positions the Body Scan 2 at the higher-feature end of its range. The company’s comparison lists features such as segmental composition and additional heart-related measurements for certain models, including ECG and AFib detection for higher-feature options. Some functions are region-specific or marked as coming soon, so check the current comparison and your local product listing rather than assuming every advertised feature is available where you live.
Choose this tier only if its added measurements are useful to you. Feature availability is not evidence that a scale can diagnose a condition or provide a clinical body-composition assessment. Consult the Withings feature comparison for model-specific and regional qualifications.

Garmin Index S2: a natural fit for Garmin Connect users
The Index S2 is worth considering if Garmin Connect is already part of your routine. Garmin describes the product as a body-weight scale with composition tracking, and an independent Tom’s Guide smart-scale guide also treats ecosystem fit as a buying consideration. Check Garmin’s Index S2 product page for current compatibility and local availability.
Eufy Smart Scale P2 Pro: a feature-rich alternative with a testing caveat
The P2 Pro is another option if you want multiple estimated metrics and app integration. In its review, TechRadar reported that some body-fat and heart-rate-related readings did not align with the reviewer’s expectations. That is a result from that review, not proof that every unit or reading will be inaccurate. It is a reason to approach its extra estimates cautiously rather than treating them as ground truth.

What body-composition readings mean
Bioelectrical impedance analysis (BIA) estimates body composition from the way a small electrical current moves through the body. In its explanation of the method used by Body+, Withings says the scale measures impedance, estimates total body water, uses that to estimate lean mass, and derives body fat from the difference between lean mass and weight. That chain of estimates is not the same as directly measuring body fat. Withings also notes that excess scar tissue may affect composition readings without affecting weight readings. Its BIA explanation is specific to its product guidance; it does not establish a universal accuracy range across brands or populations.
For everyday tracking, focus on whether readings form a useful pattern over time rather than treating any one body-fat figure as an unquestionable fact. The sources cited here do not establish a definitive clinical head-to-head accuracy comparison across these models.

What heart-related scale features can—and cannot—tell you
Smart-scale feature lists may include heart rate, vascular-age or pulse-wave features, ECG, and AFib detection, depending on the model. These are not interchangeable features, and availability can depend on geography or rollout. Check the manufacturer’s current model comparison for the specific scale and region you are considering.

| Scale | Best fit | What to verify |
|---|---|---|
| Withings Body Smart | Weight and body-composition tracking in the Withings app ecosystem | Current model features and local availability; body-composition values are estimates. |
| Withings Body Scan 2 | People seeking a premium tier with segmental composition and additional heart-related features | Whether each feature is available in your region, whether it has rolled out, and current subscription terms. |

How to get more useful trends
- Use the same scale and app when comparing readings over time.
- Pay attention to the direction and consistency of trends instead of overinterpreting one composition number.
- Separate weight tracking from body-composition estimates: they are different outputs, and the latter depends on a chain of estimates.
- Check model-specific feature availability before buying, especially for regional or newly rolling-out heart-related functions.
