30-day battery, elegant, minimal
A minimalist hybrid watch with Withings’ open data ecosystem and a 30-day battery — but deliberately stripped of the FDA-cleared ECG, SpO2, AFib, and temperature found on the ScanWatch 2.
What it measures
Optical HR (daily and overnight, with high/low-HR notifications), sleep (score, stages, breathing-quality index, regularity), connected-GPS activity, guided breathing, and cycle tracking. No 24/7 HR, SpO2, temperature, or ECG.
Regulatory status
Wellness-only — and notably stripped down: no ECG, no SpO2, no temperature, and no irregular-rhythm/AFib detection (unlike the ScanWatch 2).
Validation & accuracy
Withings has clinical credibility on its higher models, but the Light omits those validated cardiac features; HR and sleep here are wellness-grade.
Data control & export
Raw data: open — Health Mate data export and PDF reports, with Apple Health and Google Health Connect/Fit sync. API: open — the registration-based Withings developer API.
Wearability & battery
Elegant 37mm hybrid analog watch with a ~30-day battery and no charging hassle; minimalist by design.
Cost & access
One-time $249.95. No subscription required; optional Withings+ ($9.95/mo). FSA/HSA-eligible.
Who it serves
Minimalist and sleep-focused users who want an elegant, low-maintenance tracker with portable data.
Who is left out or burdened
Easy to confuse with the ScanWatch 2 — buyers expecting ECG/SpO2 get neither; no 24/7 HR; not for cardiac monitoring.
✓ Strengths
- Open developer API plus data export and PDF reports
- No subscription; own the hardware; FSA/HSA-eligible
- ~30-day battery, elegant hybrid design
- Apple Health / Google Health Connect sync
✕ Weaknesses
- No ECG, SpO2, temperature, or AFib (unlike ScanWatch 2)
- No 24/7 heart rate
- Easy to confuse with the more capable ScanWatch 2
- Not suitable for cardiac monitoring
22
Why this clinical score. With no cleared features at all — no ECG, SpO2, or AFib — it sits at the bottom of the clinical axis, below the ScanWatch 2.
74
Why this empowerment score. The same open Withings posture — developer API, data export, free cloud, no required subscription, own the hardware — keeps empowerment high.
66
Why this everyday score. Elegant and effortless with a 30-day battery, but minimalist by design with few smart or health features.

Reviews & coverage
Reviewers frame it as a stripped-down, very-long-battery hybrid for people who want clean activity and sleep tracking without ECG. The trade is the missing medical-grade sensors of the full ScanWatch.
