Oura Ring 5 launches as the world’s smallest smart ring with AI‑driven health features

Oura announced the Oura Ring 5, a 40 % smaller smart ring measuring 6.09 mm wide and 2.28 mm thick, built from lightweight, non‑allergenic titanium and rated IP68 for water resistance. The redesign includes re‑engineered sensors, more powerful LEDs and twelve signal pathways to improve accuracy across finger types and skin tones, while retaining a week‑long battery life. A portable charging case that stores up to a month of power is also supplied.

The new device expands health monitoring with “Health Radar”, adding nighttime blood‑pressure signals and breathing analysis that can flag early cardiovascular or sleep‑apnea risks. Oura’s proprietary AI model for women’s health provides menopause, perimenopause and hormonal‑birth‑control insights, and the platform now supports GLP‑1 medication tracking and Health Records integration for clinical data. Live activity tracking lets users start workouts from their phone and view real‑time metrics.

Pricing starts at $399 for base finishes and $499 for premium versions, with a $5.99‑per‑month (or $69.99‑per‑year) subscription for full data access. Pre‑orders opened on May 28, 2026, with shipping slated for June 4, 2026 in markets including the United States, India, the United Arab Emirates, Australia, Germany, Egypt and Japan. Oura also opened a flagship retail space in Harrods, London, to showcase the product.
