TL;DROura has launched the Ring 5, a smart ring that is 40% smaller than its predecessor at 6.09mm wide. It adds blood pressure pattern detection and AI-powered Health Radar monitoring. Priced from $399, it ships 4 June as Oura prepares for a US IPO at an $11 billion valuation.
Oura has launched the Ring 5, a smart ring that is 40% smaller than its predecessor and, at 6.09mm wide and 2.29mm thick, is the smallest smart ring on the market. The ring weighs as little as 2 grams depending on size, down from the Ring 4’s 7.99mm width and 2.88mm thickness. Despite the shrinkage, Oura says the Ring 5 retains the same sensor accuracy and offers up to nine days of battery life.
“We have finally achieved what I think seems like a real technological miracle,” CEO Tom Hale told CNBC. “This is what our members have been asking us for, for years.” The Ring 5 is available for preorder immediately at $399 for black and silver finishes, or $499 for gold, stealth, brushed silver, and deep rose. Shipping begins 4 June. An Oura membership is required at $5.99 per month or $69.99 per year.
Blood pressure signals and AI health monitoring
The Ring 5 introduces a feature Oura calls Health Radar, an AI-powered monitoring system that continuously tracks biometric signals including body temperature, respiratory rate, and heart rate variability in the background. When Health Radar detects patterns that suggest strain, it surfaces alerts to the wearer. Oura has built its reputation on passive health tracking that works without screens or notifications, and Health Radar extends that approach with predictive capabilities.
