For everyday weight and body-composition tracking at the lower listed U.S. price, choose the Withings Body Smart. Choose Body Scan if you specifically want handle-based segmental readings and its 6-lead ECG with AFib detection—and confirm which Body Scan generation and price you are considering before you buy.
What’s the difference between Body Smart and Body Scan?
Both scales measure weight and report a range of body-composition metrics. The main distinction is measurement scope: Body Smart measures whole-body composition, while Body Scan adds a handle for estimates of fat and muscle distribution across body zones. Body Scan also adds ECG/AFib and other cardiovascular or nerve-related assessments.

Which one is better value?
For a U.S. price reference, Withings’ 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 the distinct BodyScan 2 at $599.95. These are different listings and generations, not one settled price for every Body Scan.

#1 Best Overall
- THE ULTIMATE BODY ANALYZER - Body Scan is our most precise smart scale, for faster fitness improvement.
- INCREASE MUSCLE MASS FASTER - Precisely locating areas of muscle imbalance or excess fat may help to increase muscle mass faster.
- ACHIEVE FITNESS GOALS FASTER - Follow consistent and precise weight measurements (50 g / 0.1 lb), and track your weight trend on the scale’s high-visibility color screen or in the app.
- MONITOR CARDIOVASCULAR HEALTH - Estimates the age of your arteries to give a clearer picture of your heart health by understanding how well your heart and blood vessels are functioning.
- FOLLOW YOUR HEART - Evaluate your heart rate at every weigh-in, a good indicator of overall cardiovascular fitness.
Body Smart is the simpler value choice if your goal is routine tracking of weight, BMI and whole-body composition. The higher-priced Body Scan makes sense when you expect to use its segmental readings or ECG feature; paying more for metrics you will not use is unlikely to improve your routine.
How regional availability affects Body Scan features
Feature eligibility is not identical everywhere. Withings’ support table says Pulse Wave Velocity is EU-only, while Nerve Health Score is a medical feature available in the EU and U.S. The comparison page and support documentation can reflect different market variants, so check the feature listing for your country rather than assuming every Body Scan includes every assessment.
Rank #2
- A CLINICAL SCAN OF YOUR HEALTH - Body Smart, developed in collaboration with leading hospitals and clinical institutions, has been clinically validated.
- ACHIEVE YOUR WEIGHT GOALS FASTER - Reliably track your weight to within 50 g and view your weight trends directly on the scale's high-resolution color display.

What about the app and subscriptions?
Some full in-app experiences may be subject to a service subscription, but the available guide does not establish current feature gating or plan terms. If a specific app feature is part of your reason to buy, confirm whether it is included with the scale or requires a current subscription before checkout.

Safety and accuracy limits
Withings’ Body Smart U.S. guide describes weight, BMI, pulse and body-composition functions as wellness features, not a basis for self-diagnosis. It warns: “Do not use the device if you have a cardiac pacemaker, an implantable cardioverter-defibrillator (ICD), or other implanted electronic devices.” That warning is from the Body Smart guide; consult the Body Scan manual for model-specific safety instructions. Ask a healthcare professional if you have questions about using a scale’s measurements.
Rank #3
- A CLINICAL SCAN OF YOUR HEALTH - Body Scan, developed in collaboration with leading hospitals and clinical institutions, has been clinically validated.
- INCREASE YOUR MUSCLE MASS FASTER - Use the scale handle to precisely locate muscle imbalances and excess fat in the arms, legs, and torso.
- DETECT A CARDIAC ANOMALY - Use the electrocardiogram to identify any signs of atrial fibrillation, the most common form of cardiac arrhythmia.
- EVALUATE THE NATURAL PROTECTIVE FUCTION OF THE SKIN - Assess sweat gland activity in the feet to evaluate the natural protective function of the skin, all within seconds.
- MONITOR YOUR CARDIOVASCULAR HEALTH - Every day analyze the condition of your arteries with our revolutionary assessment that measures arterial stiffness, a significant contributor to hypertension.
Withings’ specifications explain what each model is designed to measure, but they do not establish that one is more accurate than the other in independent comparative testing. Treat the readings as tracking information, not clinical diagnosis.
