Oura Ring 4
#1 in Smart Ring · Rated 4.7
Premium sleep and health ring with deep, science-backed insights
ŌURA is the leading sleep-focused smart ring brand. The Oura Ring 4 adds flatter, more comfortable hardware, enhanced sensing, and richer sleep/biometrics data (HRV, heart rate, blood oxygen, skin temperature, sleep stages). It pairs with the Oura Membership to unlock advanced analytics and trends (the first month is included with purchase; afterward about $5.99/month or $69.99/year). The ring is designed for continuous wear, including sleep, and emphasizes privacy and data ownership. Availability spans a broad global market via the company store and retailers; its ecosystem is strong with Apple Health and Android Health integration through Health Connect, and partner integrations. The $349-$499 hardware price varies by finish (Silver/Black to Gold/Rose Gold) and is frequently discounted during major sales. Oura remains cachet-leading in premium sleep analytics and long battery life (roughly 7–8 days). ([cnbc.com](https://www.cnbc.com/2024/10/03/oura-ring-4-price-release-date.html?utm_source=openai))
