Withings BodyScan 2 Review: A Smart Scale with a Subscription Catch

Withings has launched the BodyScan 2, a smart scale that promises to bring medical-grade health monitoring into the home. The device offers a six-lead ECG, blood oxygen tracking, and nervous system analysis—but only for users who subscribe to Withings+. Reviewers are divided on its value, particularly for metrics of uncertain clinical utility.

A Smart Scale with Medical Ambitions

Withings has released the BodyScan 2, a smart scale that goes beyond basic weight tracking to offer medical-grade health metrics. According to WIRED, the device includes a six-lead electrocardiogram (ECG) capable of detecting atrial fibrillation, a condition characterized by irregular heart rhythms. It also measures blood oxygen levels (SpO2) and nervous system responsiveness, delivering a suite of data points typically reserved for clinical settings.

Subscription-Dependent Features

The BodyScan 2’s most advanced features are locked behind a Withings+ subscription, priced at $10 per month or $100 per year. Subscribers gain access to a weekly 90-second 'longevity scan,' which aggregates the device’s various measurements into a single report. Without the subscription, users are limited in the insights they can access, a point that reviewers suggest may diminish the product’s appeal for those unwilling to commit to ongoing payments.

The Withings mobile app is essential for viewing detailed results, reinforcing the company’s shift toward a software-centric business model. According to WIRED, the app is designed to be user-friendly, though the depth of data may overwhelm some users.

Mixed Reactions to Health Insights

Reviewers have expressed mixed feelings about the practical value of the BodyScan 2’s metrics. While the ECG and SpO2 readings are seen as potentially useful, the clinical relevance of the nerve response score has been questioned. According to WIRED, one reviewer described a sense of anticipation mixed with dread when awaiting the weekly longevity scan, highlighting the emotional impact of health data.

The ECG feature, while innovative for a consumer device, also elicited nervousness during testing. This underscores a broader challenge for health tech products: delivering data in a way that empowers users without causing undue anxiety. The reviewer noted that the subscription requirement may further limit the product’s appeal, as users might expect a one-time purchase to unlock all features.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

The Withings BodyScan 2 reflects a growing trend in consumer health technology: blending medical-grade diagnostics with everyday wellness tools. For founders and operators in the health tech space, this product highlights both opportunities and challenges.

On the opportunity side, the BodyScan 2 demonstrates how hardware can integrate with software subscriptions to create recurring revenue streams. The reliance on Withings+ ensures a steady customer relationship, which is attractive for investors and stakeholders. It also shows how consumer-facing products can democratize access to health metrics that were once confined to clinical settings, like ECGs and SpO2 readings.

However, the product’s limitations are just as instructive. The dependency on a subscription model may alienate users who expect one-time-purchase devices to deliver full value. Reviewers’ skepticism about the clinical usefulness of certain metrics, like nerve response scores, underscores a critical challenge: balancing innovation with evidence-based utility. Founders should note that overpromising on health insights—without clear medical validation—can erode trust and invite regulatory scrutiny.

For operators, the BodyScan 2 also raises questions about user experience. While the app is reportedly easy to navigate, the emotional response to health data—such as anxiety during ECG tests—highlights the need for thoughtful design. Health tech products must not only deliver data but also guide users in interpreting it responsibly. This product is a reminder that success in this space requires more than technology; it demands empathy and clarity.
