Are Smart Rings the Future of Health and Wellness Monitoring?

December 20, 2024

The burgeoning market for smart rings is becoming a significant trend in the domain of wearable health tech. As these rings gain prominence on retail shelves of major stores like Costco and Walmart, they are beginning to solidify their place in the consumer market. While smart rings may not be the perfect health monitoring tools, their potential to detect patterns and illnesses is drawing attention from healthcare providers and even the US military. Having long been favored by the wealthy and health-conscious for their sleep-tracking capabilities, smart rings are now poised to enter the mainstream consumer market.

In essence, smart rings serve as a significant health and wellness tool, capable of monitoring several biometric markers. As Tom Hale, CEO of Oura, characterizes them, smart rings act as a “check engine light” for the body, providing insight into the interplay between one’s biometrics and behaviors. This insight makes the technology especially useful for individuals looking to stay ahead of potential health concerns and improve their overall wellness.

The Evolution of Smart Rings

Oura has been a major player in the smart ring market since its first Kickstarter campaign nearly a decade ago. The Finnish company has continually refined its product, with the latest fourth-generation model being both slimmer and smoother, and priced between $349 to $399. This consistent innovation has helped Oura maintain a dominant presence in the smart ring space. On the financial front, Oura has recently achieved profitability after years of operational deficits. The company reached a valuation of $5.2 billion following a recent $200 million Series D funding round.

New entrants are also making their mark. The Ultrahuman Ring Air, priced similarly to Oura’s offering at $349, debuted in 2022. Additionally, Samsung has introduced its Galaxy ring at $399, and the Virtusan ring, priced at $200 and backed by David Sinclair, focuses on promoting longevity. This surge in competition not only demonstrates the high demand for these devices but also prompts improvements and innovations within the industry. As more brands enter the market and provide unique features, consumers benefit from a wider array of choices and potentially more advanced health-monitoring capabilities.

Unique Features and Capabilities

Each manufacturer seeks to differentiate their product through unique features—be it the thinnest band, the longest battery life, or the most comprehensive dataset. Commonly, smart rings track steps, monitor temperature, and log heart rate. In addition to standard fitness metrics, these devices often delve into more extensive health data, such as heart rate variability, which can indicate stress levels, and temperature monitoring, which can detect early signs of illness.

Dr. Daniel Kraft, a physician-scientist and founder in the Bay Area, supports the notion that even without being FDA-approved, smart rings offer value through consistent data collection. These devices can provide longitudinal trends, useful for tracking the impact of exercise, diet, or stress on one’s health. Kraft shares his personal experience, noting how daily exercise sessions over three months led to an observable eight-point drop in his resting heart rate. Such personalized insights can incentivize users to maintain healthy habits and make data-driven decisions about their lifestyle choices.

Brands like Virtusan enhance their offerings by pairing rings with apps that provide guided breathwork sessions, such as those by Andrew Huberman. This interactivity engages users, motivating them to make incremental lifestyle changes and observe their long-term health benefits. The combination of wearable technology and persuasive health content makes smart rings not only a tool for tracking but also a catalyst for healthier living.

Market Penetration and Consumer Adoption

Until now, the popularity of Oura rings has largely been fueled by word-of-mouth recommendations within personal and professional circles, as well as endorsements from longevity-focused physicians. Friend referrals offering a 10% discount account for a significant portion of Oura’s business. As these endorsements and referrals accumulate, they amplify the product’s credibility and adoption rate among consumers wary of investing in new technology.

The trend suggests that 2025 could be a turning point when smart rings shift from being niche gadgets to mainstream wellness tools. Industry forecasts predict a more than 20% annual growth in the smart ring market until 2030. Retail expansion has also begun, with Ultrahuman stocking its rings at major US outlets like Best Buy, Verizon, Costco, and Walmart. The company reports that over 15,000 new Ultrahuman rings are sold every month in the US alone. This retail availability, combined with increasing social proof, positions smart rings to become as common in consumers’ lives as smartphones and other everyday tech accessories.

Expanding Applications in Health Monitoring

Besides fitness tracking, smart rings are expanding into other health domains, including period tracking and illness prediction. Studies show that by monitoring metrics such as heart rate variability, temperature, and breathing rate during sleep, these devices can detect early signs of viral illnesses like COVID-19 or the flu. These insights can prove invaluable in providing early warnings and potentially mitigating the severity of illnesses through timely medical intervention.

Women’s health has also become a focus for some brands. In the US, medical research did not always include women until quite recently (1993), creating a need for more data specific to female health. Dr. Umbereen Nehal, a fem-tech founder and pediatrician, emphasizes the importance of accurate, personalized care and believes smart rings could play a vital role in preventing health issues. Women now constitute the majority of users for both Oura and Ultrahuman, accounting for 55% and 60% of the user base, respectively. Temperature tracking in these rings can assist in period tracking, helping women better plan for conception or pregnancy prevention. This added functionality makes smart rings particularly appealing to women looking for all-in-one health monitoring solutions.

Critical Evaluation and Future Prospects

As smart rings carve out their place in health and wellness, Dr. Nehal advises consumers to remain wary of the data these devices provide. It’s important for users to evaluate who tested these devices and for what specific purposes they were designed. Despite the potential, consumers should remain critical and informed, understanding that these tools are aids and not absolute solutions. Critical evaluation is essential for ensuring that the health data collected is used appropriately and effectively, rather than being misinterpreted or relied upon exclusively.

For a more holistic approach to health monitoring, a combination of various technologies could be beneficial. This includes harnessing insights from cameras, voice recorders, and other accessible tech. Mohit Kumar, founder and CEO of Ultrahuman, envisions a comprehensive health monitoring system that integrates products like the Ultrahuman Ring Air, continuous glucose monitors (CGM), and CO2 scrubbers for air quality. Such an integrated approach could provide a more complete picture of an individual’s health status, enabling more accurate predictions and better preventive care.

Government and institutional interest in smart rings is also evident. Oura has partnered with Dexcom, a CGM manufacturer, and secured a $96 million deal with the Department of Defense. Some US Army airmen are testing Oura rings to optimize performance, making decisions about rest and caffeine intake based on the ring’s feedback. Starting in 2025, Essence Healthcare, a Medicare Advantage plan, will offer free Oura rings to seniors to help control healthcare costs. These initiatives indicate a growing recognition of the potential benefits smart rings can offer not only to individuals but also to broader public health initiatives.

Dr. Kraft underscored the benefit of such data, noting that subtle health changes, often missed in brief clinical visits, could be detected by consistent monitoring through smart rings. This form of early detection could be critical in addressing health issues before they become severe. While challenges and limitations remain, smart rings appear poised to play a significant role in the future of personalized health monitoring.

In summary, smart rings are rapidly advancing as invaluable health and wellness tools, tracking various biometric data to provide users with insights into their health patterns. With broadening applications from fitness to illness prediction and period tracking, and increased adoption across different demographics, they present a promising tool for the future of personal health management. However, consumers must stay informed and critical of the data provided, ensuring these devices complement rather than replace professional medical advice. The market is set to grow significantly, with innovations and competition fueling improvements and wider accessibility.
