The Body Comp is Withings' mid-range smart scale. Besides weight and body composition, it estimates heart rate, vascular age and a nerve health score, and syncs over Wi-Fi to the Withings app.

I have not owned the Withings Body Comp. This review is built from the maker's published specs and independent reviews, linked below. For more picks, see the [Smart Scales hub](/ai-life/health/smart-scales/).

## What reviewers like

- Reliable weight tracking.
- Clean, well-designed app.
- Extra cardiovascular trends you will not find on cheap scales.

## What to watch for

- Body fat and muscle numbers vary day to day; track trends.
- The extra metrics are not diagnostic.
- Some users report sync and user-recognition glitches.

## Who should buy it

Buy it if you want the best app and heart trends. Skip it if you only need weight; cheaper scales do that fine.



## How smart scales measure body fat

Body composition scales send a tiny current through your feet and estimate fat, muscle and water from the resistance. Hydration, meals, time of day and foot position all change the result. Weight is accurate on good scales; body fat is an estimate that can differ from a DEXA scan by several points.

## Getting useful trends

Weigh at the same time each day, ideally in the morning after the bathroom and before eating or drinking. Stand barefoot on dry feet. Look at weekly averages rather than single readings.

## Users and sync

Check how many people the scale can recognize, whether it syncs over Wi-Fi or only Bluetooth, and whether it connects to Apple Health, Google Health Connect or the app you already use.

## Batteries and placement

Put the scale on a hard, flat floor. Carpet and uneven tiles throw off readings. Most smart scales run on AAA batteries; a few are rechargeable. Low batteries can cause odd readings or sync errors.

## Who should skip body composition

People with pacemakers or other implanted electronics should not use body composition features, and many makers advise against them during pregnancy. Most scales let you turn the current off and weigh only.

## How I research these reviews

For products I have not owned, I read the maker's published specs and support pages, then cross-check them against several independent reviews and, where I can, owner reports. When sources disagree, I say so. I do not list prices because they change constantly. Sources for each claim are linked under the specs table.

## Before you buy checklist

Check four things before checkout. First, the phone: some health devices only work fully with one platform, so confirm yours is supported. Second, ongoing costs: memberships, sensors, replacement heads, litter and cloud video plans can cost more over a few years than the device itself. Third, privacy: read what data the app collects, whether it is stored in the cloud, and whether you can export or delete it. Fourth, returns: holiday purchases often get extended return windows, so set a reminder to decide before yours closes.

## A note on health claims

Consumer health gadgets are wellness tools unless the maker says a specific feature is cleared by the FDA. Treat scores and estimates as trends, not diagnoses, and talk to a doctor about anything that worries you. None of this page is medical advice.

## Is the Withings Body Comp on sale for Black Friday?

It is one of the products I am watching this season. I do not list sale prices here because they change by the hour and differ by color, bundle and store. Compare against the price you see in the weeks before the sale, and check whether a bundle adds things you will not use.

## Our take

**AI Score note:** research-based, not hands-on. One of the best-designed smart scales, priced for people who will use its extras. This is my editorial read of published reviews, not a rating.

Check today's price before you buy: {{< amzn withings-body-comp "See the Withings Body Comp on Amazon" />}}.
