Despite shrinking the battery, the device still promises 6 to 9 days per charge, with a compact case adding five more full charges. It is waterproof to 100 meters and carries a new scratch-resistant coating.\n\nThe headline addition is an upgraded Health Radar that brings blood pressure monitoring and nighttime breathing tracking. The ring does not use a cuff; instead its LED sensors read changes in blood flow and blood oxygen that correlate with high blood pressure and can flag patterns suggestive of sleep apnea, viewable over 30-day windows. New features also include GLP-1 medication tracking, uploadable Oura Health Records, and live second-by-second workout metrics.\n\nThe Ring 5 is available for preorder and ships June 4, priced at $399 for black or silver and $499 for premium finishes, with a $99 charging case and a $5.99-per-month membership. The launch sharpens Oura's lead in the smart-ring market as rivals push deeper into wearable health."}}
