Verdict: The $229.95 Withings Body Comp is a polished, multi-user Wi-Fi scale for people who want automatic weight trends and extra wellness indicators in one app. It is not a substitute for DEXA, a clinical body-composition test, blood-pressure measurement, or neurological examination. Its best value is for existing Withings users; buyers who only need weight tracking will likely get more for less from Body Smart or another basic scale.

What the Body Comp measures
The Body Comp combines weight sensors with multi-frequency bioelectrical impedance analysis (BIA). It reports weight, BMI, weight trend, fat mass, muscle mass, bone mass, water, visceral-fat index, standing heart rate, vascular age and (on the U.S. model) an Electrodermal Activity (EDA) Score. Wi-Fi uploads readings automatically, while Bluetooth handles setup and can provide backup syncing. Withings claims 50 g/0.1 lb resolution and about 18 months from three AAA alkaline batteries. Dimensions are 12.8 × 12.8 × 1.1 inches. It recognizes up to eight users. See the official specifications.
“30+ biomarkers” is a marketing total, not 30 independent clinical tests. Several values are calculations or indexes derived from the same impedance, weight and profile data.
Measured, estimated and scored
- Measured directly: body weight and the electrical response detected through your feet.
- BIA estimates: fat, muscle, water, bone and visceral-fat values, generated from algorithms using factors such as height, age and sex.
- Proprietary scores: vascular age and EDA. These are wellness indicators, not medical diagnoses.
- App information: trend charts, weather and air-quality displays (when Wi-Fi is configured) and coaching content.
European units may call the nerve-related feature Nerve Health Score; the U.S. product uses Electrodermal Activity Score. Availability and terminology vary by country and hardware revision.

Setup and everyday use
- Install the Withings App and create or sign in to an account.
- Open Devices, choose Add device, and pair the scale over Bluetooth.
- Connect it to Wi-Fi for phone-free uploads and on-scale online information.
- Confirm household profiles and step on barefoot, standing still until the sequence finishes.
- Review individual metrics and trends in the app.
Wi-Fi means a phone does not need to be nearby after setup. Put the scale on a hard, level floor; soft or uneven flooring can affect readings. The color-display retail revision introduced in 2023 differs from older monochrome units, so launch-era reviews may not match current menus or screen behavior.
How accurate is it?
Weight
The 0.1-lb/50-g figure describes display resolution or claimed precision, not a guarantee that every measurement is exactly 50 g accurate. On a stable floor and under repeatable conditions, weight is the most useful output.
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.
- INCREASE MUSCLE MASS FASTER - Increase muscle mass faster by analyzing body composition to tailor efforts.
- FOLLOW YOUR HEART - Evaluate your heart rate at every weigh-in, a good indicator of overall cardiovascular fitness.
- BOOST YOUR METABOLISM - Boost your metabolism by estimating the energy your body needs every day.
Body composition
BIA estimates shift with hydration, meals, exercise, skin temperature, foot contact, placement and time of day. A post-workout reading can show an apparent change in muscle or fat that is really fluid movement. Independent coverage has generally found consistent routine readings while questioning the absolute accuracy of the composition estimates and some app behavior (Wareable’s review).

If absolute composition matters, arrange periodic professional testing such as DEXA; it is a reference-style assessment, not a replacement for daily weighing.
Rank #3
- A CLINICAL SCAN OF YOUR HEALTH - Body Comp, 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.

Make readings more repeatable
- Measure at roughly the same time, preferably before eating or exercising.
- Use clean, dry, bare feet in the same position.
- Stand still and avoid comparing morning readings with post-exercise readings.
- Interpret changes over weeks, not individual weigh-ins.
Vascular age and EDA: useful signals, not diagnoses
Withings describes Vascular Age as an age-group comparison related to arterial condition. The EDA Score reflects sweat-gland activity controlled by the nervous system. Neither tells you the actual age of your arteries, detects neuropathy, or replaces blood-pressure testing, ECG interpretation, vascular imaging or a neurological exam. In the U.S., Withings positions Body Comp as a general-wellness product (FAQ). Treat persistent or worrying changes as a reason to speak with a clinician, not as a self-diagnosis.
Withings app and Withings+
The free experience includes scale measurements, automatic synchronization and historical charts. Withings says U.S. users can still receive EDA, Vascular Age and Standing Heart Rate without Withings+. The optional service adds deeper analysis, daily engagement, guided sleep, nutrition and activity programs. The current U.S. shop listing shows one free month followed by $99.50 annually; older reviews mentioning a 12-month Health+ trial are historical. Check the checkout terms because promotions change (current shop and terms).
Rank #4
- 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.
The trade-off is account dependence and subscription prompts. If you only want readings, do not include the annual fee in your budget unless you specifically want the coaching content.
Safety and exclusions
BIA sends a small electrical signal through the body. Withings advises people with pacemakers or other implanted electronic devices not to use BIA functions, and says Body Comp has not been tested or validated for pregnancy. Metallic implants can affect results; ask a clinician about your specific implant. Ordinary stents are distinguished in Withings’ guidance, but that should not be generalized to every implant.

To disable impedance features, open Withings App → Devices → your scale → Modes → Weight-Only Mode → Enable Weight-Only Mode. This disables body composition, water, EDA/nerve activity and related electrical functions for all users linked to that scale. Read the safety FAQ before setup.
Body Comp versus alternatives
| Alternative | Choose it when… | Trade-off |
|---|---|---|
| Withings Body Smart | You mainly need weight, BMI and basic composition trends. | Fewer advanced cardiovascular and electrodermal features; usually better value. |
| Withings Body Scan/Body Scan 2 | You need segmental arm, leg and torso analysis or six-lead ECG features. | More expensive and more involved to use; check current U.S. availability. |
| Withings BodyFit | You want Withings’ newer body-composition-focused hardware. | Availability, pricing and feature support are changing. |
| Garmin Index S2 | You already live in the Garmin ecosystem. | Best benefits depend on Garmin devices and app. |
| InBody or budget Renpho-type scales | You want lower-cost BIA trend tracking or a composition-focused alternative. | Home BIA remains an estimate; ecosystem and support differ. |
| DEXA | You need a more clinically grounded occasional composition assessment. | Costs more per visit and cannot replace daily home trends. |

Who should buy the Body Comp?
Buy it if several people will share one scale, you value automatic Wi-Fi history, you already use Withings, and you will interpret the extra metrics as long-term signals. The two-year webstore warranty and 30-day direct-purchase return policy can reduce hardware risk; read the applicable terms before ordering.
Skip it if you only need weight and BMI, want clinical body-fat accuracy, dislike accounts or subscriptions, need segmental readings, or expect Vascular Age or EDA to diagnose a condition. People with implanted electronic devices should use Weight-Only Mode or choose a scale without BIA, following medical advice.
