Oura unveiled its Ring 5 this Thursday, positioning it as the most compact smart ring currently on the market. This latest iteration represents a dramatic 40% reduction in size compared to the Ring 4, slimming down from 3.5mm to 2.8mm in thickness and narrowing from 7.9mm to 6mm in width.
The Oura Ring 5 is now official! It's $50 more, but it also adds a ton of features while being 40% slimmer.

Crafted from hypoallergenic titanium, the device maintains a minimalist aesthetic that resembles traditional jewelry. According to Oura, engineers completely reimagined the internal sensor layout, incorporating enhanced LED technology and 12 reinforced signal channels to deliver superior accuracy across diverse skin tones and finger sizes.
Pre-orders opened today, with deliveries commencing June 4. Standard finishes including silver and black are available at $399, while upgraded options such as gold and brushed silver command $499.
The fifth-generation ring introduces multiple advanced tracking features, with backward compatibility extending to Ring generations 3 and 4.
The revamped Health Radar system continuously monitors vital biomarkers including core body temperature and breathing rate. A significant addition is overnight blood pressure pattern analysis, designed to identify preliminary indicators of cardiovascular concerns.
A freshly introduced Nighttime Breathing tool examines sleep respiration data across a 30-day rolling period. The system alerts users to irregularities and recommends professional medical consultation when appropriate.
For those using weight management pharmaceuticals, Oura introduced GLP-1 Insights. This feature enables medication schedule logging, side effect documentation, and weight progression tracking integrated with the ring’s biometric measurements.
Real-time activity monitoring is now embedded directly within the Oura application. During workouts, users access live metrics including speed, distance covered, and heart rate through convenient lock screen widgets. The system accommodates external heart rate monitoring devices as well.
Through a strategic alliance with Counsel Health, Oura now provides AI-assisted medical guidance within its app ecosystem. Subscribers can submit health inquiries, receive customized recommendations, and schedule appointments with certified healthcare professionals. The service debuts across 43 states, operating on a per-consultation payment model.
A newly launched Health Records tool allows users to consolidate medical diagnoses, prescription information, and laboratory results, establishing a comprehensive health profile particularly beneficial for those managing ongoing medical conditions.
The Ring 5 delivers seven full days of operation per charge. An optional portable charging solution, constructed from anodized aluminum, costs $99 and provides approximately one month of supplemental power.
Oura disclosed it expects to exceed five million paying subscribers within the current quarter, representing quadruple growth over a two-year span. The company simultaneously reported a fourfold revenue increase during this timeframe.
This past October, Oura secured $900 million through Series E funding, establishing an $11 billion valuation. Total capital raised now exceeds $1.5 billion.
Last week, the company confidentially submitted preliminary IPO documentation to the Securities and Exchange Commission. No specific timeframe for the public offering was disclosed.
CEO Tom Hale previously indicated the company could achieve nearly $2 billion in annual sales by 2026. Ring 5 membership is priced at $5.99 monthly or $69.99 annually and qualifies for FSA and HSA reimbursement.
