It covers the core measurements at a lower listed price. Choose Body Scan if you specifically want handle-based segmental readings and a 6-lead ECG with AFib detection—and confirm the exact model and current price before buying, since Withings lists both Body Scan and the newer BodyScan 2.
What are the main differences?
Both scales measure weight and provide body-composition estimates, including fat, muscle, bone, water, lean mass, BMI, BMR, and a visceral-fat index, according to Withings’ U.S. comparison page and support feature table. Their key distinction is how much additional information they offer: Body Smart focuses on whole-body tracking, while Body Scan adds a handle for segmental estimates and several cardiovascular or nerve-related features.
| Feature | Body Smart (WBS13) | Body Scan (WBS08) |
|---|---|---|
| Weight and core body-composition metrics | Yes; Withings lists weight, BMI, fat, muscle, bone, water, lean mass, BMR, and visceral-fat index. | Yes; Withings lists the same core metrics. |
| Segmental fat and muscle estimates | Not listed for this model. | Yes; the handle enables estimates across body zones. |
| Heart features | Standing heart rate. | Standing heart rate, plus 6-lead ECG with AFib detection. |
| Other listed measures | Withings lists 20+ biomarkers. | Withings lists 40+ biomarkers, including vascular age and Nerve Health Score. |
| Weight-change precision claim | Withings states 50 g detectable weight-change precision in its Body Smart FAQ. | Not stated in the cited comparison materials. |
| Power | Four electrodes; up to 15 months from included AAA batteries, according to Withings’ U.S. comparison page. | Not stated in the cited comparison materials. |
These are manufacturer-listed capabilities, not independent proof that either scale measures more accurately. Withings’ 20+ and 40+ biomarker counts are feature counts, not accuracy scores.
Which one should you buy?
Choose Body Smart for core tracking at a lower listed price
Body Smart is the practical pick if you want to follow weight, BMI, body-composition estimates, BMR, visceral-fat index, and standing heart rate without paying for Body Scan’s handle and additional assessments. Withings identifies this model as WBS13.

Choose Body Scan if you will use the added measurements
Body Scan is a better fit if segmental fat and muscle estimates or its 6-lead ECG/AFib feature are specific reasons for your purchase. Its handle is what enables the body-zone breakdown; if you only need a general trend in weight and composition, those extra readings may not justify the added cost.
Check the model generation and live price
Withings’ U.S. comparison page lists Body Smart at $129.95 and Body Scan at $379.95. A separate current U.S. store page lists Body Scan at $499.95 and BodyScan 2 at $599.95. These are different listings, so a Body Scan price should not be treated as a single stable amount; verify the precise model and live listing before ordering. See the comparison page and U.S. store.

Do the extra features work in every country?
No. Withings marks some features as region-limited. Its support table says Pulse Wave Velocity is EU-only and Nerve Health Score is a medical feature available in the EU and U.S. The feature set shown on a comparison page may not match every regional variant, so check the eligibility details for your country and exact model before buying—especially if a particular assessment is the deciding factor.
What about app access and subscriptions?
The scales’ readings are presented through Withings’ app experience, but the available product materials do not establish current subscription terms or which specific features, if any, require a paid plan. Check Withings’ current app and service terms for the model and region you intend to use rather than assuming every in-app feature is included indefinitely.

Safety and what these readings can tell you
Withings describes Body Smart’s weight, BMI, pulse-rate, and body-composition functions as wellness tools, not clinical diagnosis. Its Body Smart U.S. user guide warns: “Do not use the device if you have a cardiac pacemaker, an implantable cardioverter-defibrillator (ICD), or other implanted electronic devices.” The warning cited here is from the Body Smart guide; consult the Body Scan manual for its own instructions rather than assuming the same guidance applies unchanged.
The guide also cautions that self-diagnosis and self-treatment can be dangerous and advises consulting a doctor with questions or doubts. Treat scale measurements as tracking information, not a substitute for professional assessment.
