Editorial summaries

Oura Ring 4

The Oura Ring 4 (Gen 4, late 2024, from Oura, founded 2013 in Oulu, Finland) is a titanium biometric smart ring and the study-first archetype of the biometric cohort. Its 'Smart Sensing' recessed sensors (PPG heart rate and HRV, red and infrared blood-oxygen, multi-point skin temperature, accelerometer) feed 50-plus metrics: sleep staging and Sleep Score, Readiness, Activity, stress, cycle tracking, a VO2 Max estimate, and an LLM 'Oura Advisor'. It is sold as a purchase (from about $349) plus a required Oura Membership ($5.99/month); the AI augments genuine biometric sensing rather than being the product. DEPLOY records commercial maturity and a reported $11 billion valuation (October 2025). The verified-vs-claimed throughline: Oura is positioned as general wellness and is not FDA-cleared for diagnostics, and it ran a blood-pressure study in December 2025 before marketing blood pressure, the study-first counterpoint to Whoop's market-first BP Insights. Oura is also the patent-holder in the smart-ring litigation (RingConn settled; Ultrahuman was ITC import-banned via the '178 patent).

Withings ScanWatch

The Withings ScanWatch (the ScanWatch 2 at about $349 and the ScanWatch Nova, including the Nova Brilliant at about $600, November 2024; from Withings, founded 2008 in France and independent since buying itself back from Nokia in 2018) is the hybrid-analog entry of the biometric cohort: a conventional analog watch dial paired with medical sensors (optical PPG, electrical ECG, SpO2, and TempTech24/7 continuous temperature) and about 30-day battery. Its cleared features include ECG (for AFib, sinus rhythm, and high heart rate, cleared 2021, with an OTC ECG clearance in 2025), SpO2 with breathing-disturbance detection, and temperature trends, with an optional Withings+ subscription (~$9.95/month). It carries substantial peer-reviewed cardiologist validation for the size of the company. Cap-flag: as a French maker it is cleared in both the EU and the US, with different specific indications by region.
