Editorial summaries

Evie Ring (and EvieMED)

Movano Health's Evie Ring is a women's-health-focused smart ring (menstrual-cycle tracking, sleep, energy, heart rate, SpO2, and mood and goal trends; general-wellness, not a diagnostic) and the lifecycle-state-paused archetype of DEPLOY's biometric ring sub-cohort. The verified-vs-claimed distinction is critical: Evie Ring sales are PAUSED, not discontinued. Following Movano Health's Corvex reverse merger (closed March 19, 2026), an AI-infrastructure pivot, and a 1-for-10 reverse split, the company paused Evie Ring sales while a divestiture of its EvieMED clinical line is pending. EvieMED (the B2B/clinical variant) is an FDA 510(k)-cleared pulse oximeter and heart-rate device (December 2, 2024) for clinical trials, remote patient monitoring, and payors and pharma. DEPLOY records the consumer Evie Ring at paused availability with no current retail price. Aggregators routinely flatten this as 'Movano discontinued the Evie Ring'; the accurate state is sales-paused amid a corporate pivot, with the EvieMED divestiture pending (an intention where not yet closed). Movano Health trades as NASDAQ: MOVE (CEO John Mastrototaro).

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).
