Oura Ring Gen 4
Price: $349 (plus $5.99/month subscription after 6-month free trial)
The Oura Ring has long been considered the gold standard in smart rings, and the fourth-generation device continues this tradition while addressing some key limitations of previous models.
Design and Comfort
The Gen 4 maintains Oura's signature minimalist aesthetic but is now 30% thinner than its predecessor, making it significantly more comfortable for all-day and all-night wear. Available in silver, black, stealth black, gold, and rose gold finishes, the ring features a subtle flat edge on its outer surface—the only visual indication that this isn't an ordinary piece of jewelry.
The internal sensors sit flush against your finger, and the titanium construction strikes an excellent balance between durability and lightweight comfort. Most users report forgetting they're wearing it after just a few days of use.
Health and Fitness Features
Oura continues to excel in sleep tracking, with the Gen 4 offering best-in-class accuracy for sleep stages, timing, and quality. New to this model is advanced REM sleep analysis that correlates with polysomography studies at over 90% accuracy.
Fitness tracking has seen substantial improvements, with continuous heart rate monitoring now sampling at twice the frequency of the Gen 3. The addition of a blood oxygen sensor provides valuable SpO2 data throughout the night, while stress monitoring through heart rate variability (HRV) analysis continues to be Oura's strong suit.
The Gen 4 also introduces a temperature-based illness prediction feature that can alert you to potential sickness up to three days before symptoms appear by analyzing subtle changes in your body temperature, respiratory rate, and HRV patterns.
Battery Life and Charging
Battery life has been extended to an impressive 8 days of typical use, addressing a common complaint about earlier generations. The charging cradle has been redesigned to be more compact and travel-friendly, and a full charge takes just over an hour.
App Experience
The Oura app remains one of the most polished and intuitive in the wearable space, with thoughtfully presented data and actionable insights rather than just raw numbers. The subscription model still applies, though new users get a 6-month free trial.
Standout Features
- Best-in-class sleep tracking with advanced REM analysis
- Illness prediction algorithm with impressive accuracy
- Extended 8-day battery life

Price: $299 (no subscription)
After years of rumors, Samsung finally entered the smart ring market in late 2024, and the Galaxy Ring has quickly established itself as a formidable competitor, especially for those already in the Samsung ecosystem.
Design and Comfort
The Galaxy Ring features a concave inner surface that houses the sensors while maintaining comfort. Available in three finishes (silver, black, and gold), the titanium construction feels premium and durable. At just 2.7g for the smallest size, it's among the lightest options available, making it exceptionally comfortable for continuous wear.
The sizing process deserves special mention—Samsung offers a comprehensive sizing kit with 13 different options to ensure a perfect fit, addressing one of the most common issues with smart rings.
Health and Fitness Features
While not quite matching Oura's sleep-tracking prowess, the Galaxy Ring comes impressively close for a first-generation product. Its standout health feature is its continuous blood pressure monitoring capability—something no other smart ring currently offers.
The ring also excels at activity tracking, automatically detecting and logging workouts with impressive accuracy. Heart rate monitoring is on par with leading smartwatches, and the stress tracking features benefit from Samsung's years of experience with their Galaxy Watch line.
Battery Life and Charging
The Galaxy Ring offers approximately 5 days of battery life—not as impressive as Oura but still sufficient for most users. The charging case doubles as a power bank that can recharge the ring three times before needing to be plugged in, making it ideal for travelers.
App Experience
The Galaxy Ring integrates seamlessly with Samsung Health, making it a natural choice for Galaxy smartphone users. The app provides comprehensive health data visualization and actionable insights, though it can feel overwhelming to new users due to the sheer volume of information presented.

Price: $299 (no subscription)
The Ultrahuman Ring Air 2 represents a significant evolution from its predecessor, with particular emphasis on metabolic health and recovery optimization, making it ideal for serious athletes and health enthusiasts.
Design and Comfort
The Ring Air 2 features a striking yet understated design with a slightly wider band than competitors. Available in matte black, silver, and a limited-edition copper finish, the tungsten carbide construction makes it exceptionally scratch-resistant—a major advantage for active users or those working with their hands.
While slightly heavier than some alternatives, most users report that the weight distribution makes it comfortable for continuous wear after a short adjustment period.
Health and Fitness Features
Where the Ultrahuman Ring truly stands out is in its metabolic health tracking. The ring uses a combination of heart rate, HRV, and temperature sensors to estimate blood glucose stability throughout the day, even without a continuous glucose monitor.
Recovery tracking is another area where this ring excels, providing detailed readiness scores based on sleep quality, HRV trends, and other physiological markers. This makes it particularly valuable for athletes following intensive training programs.
Sleep tracking is comprehensive if not quite as nuanced as Oura's, but the addition of skin conductance sensors provides unique stress tracking capabilities that few competitors can match.
Battery Life and Charging
Battery life is solid at approximately 7 days of typical use, and the innovative magnetic charger attaches seamlessly to the ring without requiring removal, allowing for quick top-ups during shower time or other brief periods when you're not wearing the device.
App Experience
The Ultrahuman app has improved significantly in recent updates, offering a clean interface focused on metabolic health, recovery, and stress management. While there's no subscription required, certain advanced features can be unlocked through one-time in-app purchases.
Standout Features
- Unmatched metabolic health insights
- Superior recovery tracking for athletes
- Exceptional scratch resistance
- Innovative magnetic charging solution
- No subscription required
Limitations
- Slightly heavier than competitors
- Less emphasis on general lifestyle metrics
- App can be overly technical for casual users
RingConn Smart Ring
Price: $229 (no subscription)
The RingConn Smart Ring has quickly gained popularity as a value-oriented option that doesn't compromise on essential features, offering perhaps the best price-to-performance ratio in the market.
Design and Comfort
The RingConn features a sleek, rounded design that's available in black, silver, and gold finishes. The ceramic outer shell combined with a titanium inner ring creates a lightweight yet durable construction that weighs just 3.1g for the medium size.
The ring profile is slightly thicker than premium competitors, but the curved edges help maintain comfort during extended wear. Most users report minimal adjustment period, though some note it can feel more noticeable during sleep than thinner alternatives.
Health and Fitness Features
RingConn offers surprisingly comprehensive health tracking that rivals more expensive options. Sleep tracking is detailed and accurate, breaking down sleep stages and providing useful quality metrics that compare favorably with laboratory standards.
Activity tracking automatically recognizes 20 different workout types, and heart rate monitoring performs reliably during both rest and exercise. The ring also tracks blood oxygen levels during sleep and provides detailed HRV analysis for stress management.
The most impressive feature given the price point is the comprehensive women's health tracking, which uses temperature sensing to predict menstrual cycles and fertility windows with accuracy comparable to dedicated devices.
Battery Life and Charging
Battery life is a respectable 5-6 days, and the charging cradle is compact and well-designed. A complete charge takes approximately 90 minutes, with a quick-charge feature providing 24 hours of use from just 15 minutes of charging.
App Experience
The RingConn app has matured significantly since its initial release and now offers a clean, intuitive interface that presents data in easily digestible formats. There's no subscription requirement, and all features are available with the initial purchase.

Design and Comfort
The Circular Ring Slim lives up to its name with one of the thinnest profiles on the market—just 2.2mm at its slimmest point. Available in black, silver, gold, and a unique "midnight blue" finish, the ring features subtle LED indicators cleverly integrated into the design that can provide visual feedback for notifications.
The aerospace-grade titanium construction feels premium, and the inner surface is gently curved to maximize comfort. At just 2.5g, it's among the lightest options available, making it virtually unnoticeable during wear.
Health and Fitness Features
Health tracking encompasses all the essentials, with particularly strong performance in heart rate variability monitoring and stress management. Sleep tracking is comprehensive, though not quite as detailed as Oura or Samsung options.
What sets the Circular Ring apart is its "Kira" AI assistant, which provides highly personalized coaching based on your health data. After a learning period of about two weeks, the system begins offering tailored recommendations for sleep improvement, stress management, and activity optimization that become increasingly accurate over time.
Battery Life and Charging
Battery life is approximately 5 days of continuous use, and the charging case is among the most compact available, easily fitting in small pockets or bags. The case itself holds enough power for three full charges of the ring.
App Experience
The Circular app features a clean, minimalist design that prioritizes actionable insights over raw data. Basic features are available without subscription, but the "Kira+" subscription unlocks advanced personalization, detailed trend analysis, and unlimited history.
Standout Features

Amazfit Helio Ring
Price: $249 (no subscription)
The Amazfit Helio Ring is the newest entrant in our lineup, released in early 2025. It brings Amazfit's expertise in affordable fitness wearables to the smart ring market, with particular emphasis on sports performance and recovery.
Design and Comfort
The Helio Ring features a distinctive design with a slightly raised sensor array on the inner surface that creates a secure fit during intense activities. Available in black, silver, and a unique "graphite" finish, the aircraft-grade aluminum construction offers a good balance of durability and weight.
At 3.6g, it's not the lightest option, but the weight distribution feels balanced, and the secure fit means it stays in place even during vigorous exercise. The outer surface features a subtle matte texture that resists fingerprints and maintains a clean appearance.
Health and Fitness Features
As expected given Amazfit's focus, sports tracking is where the Helio Ring truly excels. The ring can detect and analyze 25 different sports with impressive accuracy, providing detailed metrics specific to each activity.
The Helio also introduces "Training Effect" analysis, which quantifies the impact of each workout on your aerobic and anaerobic fitness, making it particularly valuable for serious athletes. Recovery guidance is equally impressive, with daily readiness scores and suggested training intensities based on your physiological state.
Sleep tracking and general health metrics are comprehensive, with continuous heart rate monitoring, SpO2 tracking, and stress analysis through HRV. Temperature sensing is used primarily for recovery analysis rather than cycle tracking or illness prediction.
Battery Life and Charging

App Experience
The Helio Ring integrates with the Zepp app ecosystem used by other Amazfit devices, providing a familiar experience for existing users. The app focuses on detailed performance analysis and actionable training insights, though it can appear cluttered to those primarily interested in general health metrics.
Standout Features
- Exceptional battery life (9 days)
- Superior sports performance tracking
- "Training Effect" analysis for serious athletes
- Secure fit for active use
- No subscription required
Limitations
- Slightly heavier than premium alternatives
