Finnish health tech company Oura unveils the Ring 5, a smart ring that's 40% smaller than its predecessor while adding AI-powered health insights through Oura Advisor. The $399 device introduces Health Radar for proactive monitoring of blood pressure and breathing patterns, marking a shift from passive tracking to preventive health management.

Oura Ring 5 Shrinks Form Factor Without Sacrificing Performance

Finnish health tech company Oura has launched the Oura Ring 5, positioning it as the world's smallest smart ring at just 6.09mm wide and 2.28mm thick—a 40% reduction from the Oura Ring 4

1

. The smaller and lighter design addresses one of the most common complaints about wearable technology: bulk. Available for preorder today at $399 for silver and black finishes, with premium colors including Stealth, Brushed Silver, Gold, and Deep Rose priced at $499, the device ships June 4

. The titanium exterior features a new physical vapor deposition (PVD) coating for improved scratch resistance, while maintaining IP68 water resistance up to 100 meters

Despite the dramatic size reduction, Oura claims the Ring 5 delivers better accuracy than previous models. The device incorporates LEDs four times more powerful than the Ring 4, paired with redesigned optical sensors positioned closer to the skin for improved signal detection across different finger shapes and skin tones

5

. The smart ring now features 12 independent signal pathways, down from 18 on the Ring 4, but Oura's VP of Product Jason Russell explained that the combination of more powerful LEDs and three beefier photodetectors offers better, more accurate readings

3

. Battery life extends to six to nine days per charge, up from the Ring 4's five-to-eight-day range, and a new portable Charging Case ($99) can add an extra month of battery life with roughly five full charges

Health Radar System Enables Proactive Health Monitoring

The most significant advancement arrives through software, as Oura shifts from passive health tracking to preventive health management with its new Health Radar system. Building on the Symptom Radar feature introduced in 2024, Health Radar continuously analyzes biometric patterns in the background to flag subtle changes before they become obvious problems

1

. At launch, the system focuses on two critical functions: Blood Pressure Signals and Nighttime Breathing. The blood pressure monitoring capability continuously analyzes biometric trends that may correlate with cardiovascular strain, with a new Nighttime Blood Pressure feature monitoring whether blood pressure drops appropriately during sleep—a metric that may reveal cardiovascular risks that daytime readings miss

5

. Users can also add cuff readings to provide additional context for more comprehensive biometric analysis.

Nighttime Breathing provides a rolling 30-day view of breathing disturbances during sleep to identify changes that could affect sleep quality or signal underlying issues. Earlier this month, Oura announced a partnership with Resmed that offers users with elevated nighttime breathing alerts access to sleep health resources, complete sleep assessments, and the option to connect with independent healthcare providers for potential diagnosis and treatment

1

. This represents a fundamental shift in how wearable technology approaches wellness, moving from simply presenting data to actively identifying potential health concerns and connecting users with care pathways.

AI-Powered Health Insights Through Oura Advisor and Counsel Health Partnership

Oura is positioning the Ring 5 as a proactive health platform centered around AI-powered health insights. The company is partnering with Counsel Health to integrate AI-assisted health guidance with access to licensed physicians through Oura Advisor, the company's large-language-model-powered assistant that debuted last year

1

. Through this integration, users can ask health questions, receive personalized guidance, and connect with healthcare professionals from the app in 43 states where such services are allowed

3

. The platform also incorporates Oura's proprietary AI model for women's health, expanding the scope of specialized health tracking features.

For metabolic health management, Oura is introducing GLP-1 insights that allow users to log and track dosing schedules, side effects, and weight changes. The feature helps users keep track of their medication and monitor how it affects their metrics—for example, GLP-1s can cause a mild increase in resting heart rate

2

. Users can also upload lab results directly into the app and chat with Oura Advisor about the findings, though the company reminds users that AI health features are capable of hallucinations and poor advice and should not replace medical professionals

2

. The subscription model remains at $5.99 per month or $69.99 annually, unlocking these advanced health tracking features and AI-driven analytics

Enhanced Fitness Tracking and Third-Party Integration

Fitness tracking receives a substantial overhaul with the Ring 5. A new live activity mode lets users start workouts from the app and view heart rate, pace, and distance in real time through lock-screen widgets on iPhone, eliminating the need to unlock phones mid-session

1

. For activities where a smart ring can be uncomfortable, such as powerlifting, the app now supports third-party heart rate monitors and select devices, allowing users to continue capturing live workout data without wearing the ring itself

2

. Oura also claims its updated Automatic Activity Detection is significantly more accurate than previous generations, particularly for lower-motion exercises like Pilates.

Market Competition and Privacy Considerations

The smart ring market is becoming increasingly competitive, with brands like Samsung, RingConn, and Ultrahuman introducing alternatives that challenge Oura's dominance

4

. RingConn offers a subscription-free experience, while Ultrahuman emphasizes metabolic health tracking, giving consumers more choices. Given Oura's controversy last year over its Palantir partnership, the company now offers expanded options for deleting data, including a new Time-based Data Deletion feature that allows users to erase information from specific time windows

2

. The Ring 5 also includes a new Locate feature for tracking misplaced rings and charging cases through the app, rolling out to Gen 2 devices and newer

1

. Oura is also launching a Brain Health Study with Cambridge Cognition, allowing users to opt in to share their data as the company studies how metrics correlate to cognitive performance
