Summary of Key Points
Smart rings, these screenless gadgets, are rapidly gaining popularity: global shipments are expected to double to 4 million units by 2025, with the leading brand Oura accounting for 74% of the market share and a valuation of $11 billion, preparing for an IPO. They have outperformed smartwatches by offering a seamless wearing experience and continuous sleep monitoring capabilities. However, they also face challenges such as weak warning systems, inaccurate exercise data, and unclear regulatory frameworks. Domestic and international players have different strategies: Oura focuses on a "hardware + subscription" model, while Samsung aims to enhance its ecosystem; domestic companies either develop medical-grade sensors or integrate their products into comprehensive health solutions. Whether smart rings can evolve from a novelty to a necessity depends on whether doctors will accept their data as credible.
Why Smart Rings Outperform Smartwatches?
The success of smart rings lies in addressing the key issues associated with wearing smartwatches:
- Seamless Wearing: Rings weigh only 3-6 grams, have no screen light, and offer a battery life of 5-10 days. They can be worn while sleeping without any discomfort (43% of wristwear users give up due to battery life or nighttime irritation).
- Advanced Sleep Monitoring: Since 95% of people sleep every day, accurate sleep tracking is crucial. Rings are placed closer to the fingers, where blood vessel density is higher and movement is minimal, resulting in more precise sleep phase detection (Oura achieves 53% accuracy in laboratory tests).
- Female Health Benefits: Oura's continuous temperature monitoring works with FDA-approved digital fertility apps like Natural Cycles, giving it official recognition as a health tool and moving it beyond the realm of ordinary electronics.
Three Challenges Hindering Smart Rings from Becoming More Useful
Despite their popularity, smart rings still have unresolved issues:
1. Weak Warning Systems: Without a screen or significant vibrations, they can only record data and cannot provide real-time alerts (e.g., for low heart rate or atrial fibrillation). Most rings use PPG (photoplethysmography) signals, which can only indicate irregular pulse patterns, not provide ECG-level insights (only Circular Ring 2 offers this feature).
2. Inaccurate Exercise Data: Intense exercise causes significant changes in blood flow, leading to larger heart rate variations (e.g., RingConn reads 120 compared to Apple Watch’s 138). For accurate tracking during physical activities, smartwatches are still superior.
3. Unclear Regulations: The FDA classifies most smart rings as "low-risk health devices," not medical devices. Blood glucose monitoring is a potential market, but the FDA has not authorized any smart wearables for non-invasive blood glucose measurement.
Different Approaches from Various Players
There are three main types of players in the smart ring market, each with distinct strategies:
- Oura Model: Selling the ring for $349 and charging $5.99 per month for core health analysis services, with an 80% member retention rate. They profit from data and algorithms (e.g., a recovery score) with the screen serving as a secondary feature.
- Whoop Model: Going even further without a screen, they have developed a screenless band that has received FDA ECG certification, bringing them closer to clinical applications.
- Ecosystem Enrichers: Samsung’s Galaxy Ring integrates into the Galaxy Watch ecosystem, focusing on sleep monitoring while the watch handles exercise tracking.
Domestic Players’ Approaches
Domestic companies are taking different paths:
1. Developing Medical-Grade Sensors: Huawei’s Xuanji technology, in collaboration with Peking Union Medical College Hospital, has achieved 80.1% accuracy in non-invasive uric acid screening. Other companies are working on fingertip ECG and continuous blood pressure monitoring rings, aiming for high data accuracy and clinical reliability.
2. Integrating into Health Platforms: JD Health connects ring data with blood glucose meters for blood sugar management, while Ping An Health uses AI and doctors for follow-up services. Alibaba Health offers health management solutions, seeing the hardware as a gateway to additional services and revenue.
The Transition from Novelty to Necessity
To become a necessity, smart rings must overcome the barrier of doctor acceptance:
- Patent Disputes: Oura has sued Samsung for patent infringement, while Samsung offers a $399 ring without a subscription, sparking a price and patent battle.
- Competitive Pressure: Lower-priced alternatives from Chinese manufacturers may reduce the value of smart rings, leaving data credibility as the deciding factor.
- Standards for Acceptance: Accurate data, stable algorithms, and clear error reporting are essential. Without these, smart rings will remain accessories that generate reports but cannot become essential medical tools.
The story of smart rings is just beginning. Whether they can reach the "medical-grade" category depends on their ability to overcome these barriers.
