Oura Ring 4 vs RingConn Gen 2: The Ultimate Smart Ring Showdown (2025 Edition)
In 2025, smart rings have firmly established themselves as go-to wearables for anyone seeking discreet, accurate health and fitness tracking. With new launches and rapid advances, two frontrunners have grabbed the most attention this year: the Oura Ring 4 and the RingConn Gen 2. Let’s take a feature-by-feature look at how these innovative rings compare, helping you make the best choice for your needs.
Design and Comfort
Both the Oura Ring 4 and RingConn Gen 2 adopt sleek, lightweight titanium construction. The Oura Ring 4 maintains a classic jewelry-like aesthetic, available in a spread of metallic finishes (silver, brushed titanium, matte black, stealth black, rose gold, gold) with a subtle profile. In contrast, RingConn’s Gen 2 ring takes thinness and comfort up a notch—its 2mm thickness feels more like a real ring and weighs in at only 2-3g depending on size. This not only makes the RingConn almost unnoticeable during daily wear, but it also boosts long-term comfort, especially for sleep tracking.
Tracking Features
When it comes to tracking, both rings are packed with sensors: photoplethysmography (PPG) for heart rate, skin temperature, accelerometer, and more.
The Oura Ring 4 distinguishes itself with its Daily Readiness 2.0 AI-powered index. It uses sleep, activity, and stress data to intelligently guide everything from your workouts to your recovery days. Its body-temperature mapping even syncs with your biological clock for hormone and cycle insights. Sleep tracking is robust, tracking stages (light, deep, REM), latency, and overall quality. Oura remains the gold standard for deep recovery and sleep metrics.
RingConn Gen 2 matches much of this functionality, adding SpO2 and more customizable fitness tracking options, including four dedicated workout modes. Where RingConn shines is with real-world performance—its app delivers fast, easy-to-read health summaries, and ongoing firmware updates promise to further improve accuracy and features.
Battery and Charging
Battery life is a major differentiator in the smart ring market.
The Oura Ring 4 delivers 4–8 days (depending on usage). RingConn Gen 2 undercuts much of the competition with up to 12 days between charges, and its magnetic charging case doubles as an on-the-go power bank for 15 full recharges. This convenience means less user interruption and more continuous data.
Subscription and Pricing
Oura Ring 4 starts at $349 and requires a $5.99/month subscription for advanced analytics, insights, and historical data access. The subscription enables powerful features but can turn off budget-focused buyers.
RingConn Gen 2 starts at $299, and—crucially—has zero subscription fees. Once purchased, you get full app functionality for life, making it appealing for those who want to avoid ongoing costs.
Durability and Compatibility
Both rings are built to last with titanium bodies. Oura adds diamond-like carbon (DLC) and physical vapor deposition (PVD) coatings for extra durability. Both are waterproof, suitable for swimming and shower use.
For compatibility, both pair with iOS and Android, supporting integration with Google Fit and Apple Health, so your data syncs easily with the broader health ecosystem.
User Experience and App
Oura’s companion app stands out for design and usability, offering deep health insights and a polished experience. You’ll find clear graphs, actionable tips, and recovery recommendations.
RingConn’s app is streamlined and straightforward, focusing on essential stats and fitness insights. It’s praised for its rapid updates and openness to new third-party integrations and features.
