It pairs heart-rate and heart-rate-variability, blood-oxygen-trend, multi-point temperature, and accelerometer sensing with sleep staging and a Sleep Score, a Readiness Score, activity, stress, cycle tracking with Natural Cycles integration, a VO2 Max estimate, and an AI Oura Advisor across more than 50 metrics, sold by purchase plus a required membership of $5.99 a month. On FDA status, the Oura Ring 4 itself has no clearance and is marketed as a general-wellness product, with its only cleared-feature route via partner integrations such as the FDA-cleared Natural Cycles birth-control app consuming Oura temperature data, where the clearance belongs to the partner. Oura is the disciplined counter-case to Whoop in the verified-versus-claimed framework: it launched a Blood Pressure Profile Study in December 2025 to pursue a hypertension feature, but that feature is investigational and not cleared, so Oura is running the clearance path before marketing blood pressure, in contrast to Whoop's market-first posture that drew an FDA warning letter. A valuation correction is worth recording: Oura is valued at $11 billion after a roughly $900 million Series E in October 2025 led by Fidelity with revenue reportedly above $1 billion in 2025, not the stale roughly $5 billion figure. Its clinical-validation posture is the strongest and growing in the cohort specifically on sleep, with a 2025 Brigham and Women's Hospital study finding it the most accurate consumer sleep tracker for four-stage classification against polysomnography, while its posture is validated wellness rather than a cleared medical device except via partners, and its blood-pressure feature and the accuracy of its Readiness and VO2 Max metrics are investigational or not clearance-validated.","formFactor":"biometric","maturityStage":"commercial","lifecycleState":"active","supersededByModelId":null,"specs":{"notes":[{"label":"FDA clearances (minimal - the disciplined posture)","value":"The Oura Ring 4 itself has NO FDA clearance; it is marketed as a GENERAL-WELLNESS product under FDA's general-wellness policy.
