A scale — not worn
A connected health-station scale with an FDA-cleared 6-lead ECG (AFib detection), segmental body composition, and a vascular-age estimate — strong on patient data control, but a standing measurement rather than a worn device.
What it measures
Segmental body composition (4 weight sensors + multi-frequency bioimpedance), a 6-lead ECG via a retractable handle (AFib detection), heart rate, and a vascular-age estimate.
Regulatory status
FDA 510(k)-cleared in the US for AFib detection from the 6-lead ECG (the US launch was held until clearance landed in Aug 2023). Some EU-marketed metrics (e.g., nerve-health/skin conductance) are outside the US clearance.
Validation & accuracy
The AFib-detection algorithm was validated for FDA clearance; the ECG is medical-grade. Bioimpedance body composition is consumer-grade, not a clinical reference method.
Data control & export
Raw data: open — Health Mate exports full account data as CSV and ECG recordings as PDF, with Apple Health / Google Health Connect sync. API: restricted — a partner-gated Withings developer API.
Wearability & battery
A premium bathroom scale you stand on with a handle for the ECG and hand-to-foot bioimpedance — a daily standing measurement, not a worn device.
Cost & access
One-time $399.95, no subscription for the cleared features; optional Withings+ (~$9.95/mo). FSA/HSA-eligible.
Who it serves
Households wanting at-home AFib screening, weight, and body-composition trends with portable data and no recurring fee.
Who is left out or burdened
Not a worn device; bioimpedance is approximate; some EU metrics aren’t available in the US.
✓ Strengths
- FDA-cleared 6-lead ECG with AFib detection
- Segmental body composition and vascular-age estimate
- CSV export, ECG PDF, and Apple Health / Health Connect sync
- No subscription for cleared features; FSA/HSA-eligible
✕ Weaknesses
- A scale — not a worn device
- Bioimpedance body composition is approximate
- Some EU metrics are outside the US clearance
- Partner-gated API rather than fully open
74
Why this clinical score. An FDA-cleared 6-lead ECG with AFib detection is genuinely actionable, putting it high on the clinical axis; held below dedicated cardiac/CGM devices because measurement is intermittent and standing.
76
Why this empowerment score. The open Withings posture — CSV export, ECG PDF, third-party sync, own the hardware, no required subscription — keeps empowerment high.
46
Why this everyday score. As a scale it scores low on the everyday-wearable axis by design: not worn, used for brief daily measurements.

Reviews & coverage
Reviewers are impressed by the segmental body-composition, vascular-age and ECG features of this premium smart scale. The downsides are the steep price and some features arriving gradually or region-gated.
