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).

RingConn (Gen 2 / Gen 3)

RingConn (the Gen 2 at about $279, plus the Gen 2 Air and a Gen 3 arriving late May 2026; from RingConn, Shenzhen) is the subscription-free archetype of the biometric ring sub-cohort: all standard features are free for life, the core positioning against Oura's required membership and Whoop's subscription-only model. Its sensors (PPG, skin temperature, SpO2, accelerometer) drive sleep, heart rate and HRV, and a deep-learning sleep-apnea / AHI screening feature, with 10-to-12-day battery (the charging case extends to about 150 days). The verified-vs-claimed throughline: the sleep-apnea / AHI feature is a company-claimed screening capability (RingConn cites about 90.7% accuracy) that is NOT FDA-cleared. RingConn's own materials say it is 'actively pursuing clearance' and 'not intended to diagnose'; DEPLOY records the AHI claim as claimed, not cleared, the direct counterpoint to the genuinely-cleared Happy Ring in the same form factor. On the patent front, RingConn settled and licensed cleanly in the smart-ring ITC litigation; it was not import-banned, unlike Ultrahuman. Price is $279, subscription-free.
