Honestly, I used to think smart rings were a bit… well, dumb. What was the point? They often cost as much as, or even more than, a smartwatch, and many of them slapped a monthly subscription fee on top of that high price.
I mean, are we going to need a subscription to use our toaster next? But after spending time with it, the RingConn Gen 2 is probably the first smart ring that didn’t just impress me, but that I now actually recommend.
I’ve found myself recommending this ring are its frankly insane battery life, the convenience of its charging case, and a surprisingly comprehensive set of features packed into a tiny form factor.
Key Takeaways
- RingConn Gen 2 offers standout battery life up to 12 days, with a charging case that adds up to 150 days of reserve power.
- Sleep apnea detection sets it apart, providing early alerts and health insights with 90%+ accuracy.
- No monthly fees, offering full feature access at a one-time cost starting at $299, unlike Oura or Ultrahuman.
- Comfortable, durable titanium build and minimalist app interface make it ideal for new health tech users.
- Best smart ring for health tracking in 2025, combining affordability, innovation, and polished user experience.
First Impressions & Design of RingConn Gen 2: Light, Sleek, and Surprisingly Comfortable
When I first unboxed the RingConn Gen 2, I was immediately struck by how small and lightweight it is. RingConn claims the Gen 2 is thinner, lighter, and narrower than their first generation ring, with weights as low as 2 grams.
It’s made from titanium alloy which gives it a feeling of durability. Holding it, it feels lighter and thinner than other smart rings I’ve tried, like the Ultrahuman. On my finger, it’s honestly barely noticeable.
The design is a little unique, I would say it is square-ish. It’s rounded like any ring, but the edges have a distinct shape. The top surface is concave, which is a smart design choice to help protect it from scratches when you rest your hand down.
The sides and bottom are convex, which makes it feel more comfortable and prevents it from digging into your finger. This design language is even mirrored in the charging case. The ring comes in different colors and finishes, including matte and glossy options for the Gen 2.
Sizing is crucial with smart rings because their internal components make standard ring sizes different. RingConn, like other smart ring companies, uses a slightly different sizing method. They emphasize using their free sizing kit before ordering the actual ring to ensure the best fit.
I found this important because even comparing it to another size 10 smart ring I owned, the RingConn felt a little tighter.
RingConn recommends wearing the sizing rings for a night or two to account for finger swelling, and suggests wearing the final ring on your index, middle, or ring finger for optimal accuracy.
The ring is also built tough, with an IP68 water resistance rating. This means it can handle showers, swimming (up to 100 meters according to RingConn’s official statement), and general daily exposure without issue. I’ve worn it showering and swimming without problems.
Health Tracking Features of RingConn Gen 2: Sleep, Vitals, and Sleep Apnea Detection
The RingConn Gen 2 line packs a ton of sensors inside, allowing for continuous health monitoring. It tracks a wide range of metrics:
- Sleep: Including stages (REM, Light, Deep), efficiency, quality, and time in bed. It can also monitor naps.
- Activity: Steps, calories burned (including all-day calories, not just during workouts), distance.
- Stress: Provides a stress score and charts showing daily patterns. It uses HRV for this.
- Vital Signs: Heart Rate (including Resting Heart Rate – RHR), Heart Rate Variability (HRV), Blood Oxygen Levels (SpO2), Skin Temperature, and Respiratory Rate. It monitors HR and SpO2 24/7, every 2.5 minutes. It’s notable that it includes SpO2, a feature that was disabled on some Apple Watch models due to patent issues.
- Menstrual Health Support: Tracks changes in body temperature for period predictions.
I was pleasantly surprised by the accuracy of the data. The RingConn Gen 2 was often very close to significantly more expensive competitors like Oura and Whoop on important metrics.
It is good at capturing trends, while like most health professionals often agree, the main value of wearable health tech is tracking trends, not exact statistics.
There is one feature of RingConn Gen 2 that truly stands out is Sleep Apnea Detection. This is a significant feature, particularly because sleep apnea is often undiagnosed.
RingConn claims it’s the first smart ring to offer Obstructive Sleep Apnea (OSA) monitoring, with over a 90% accuracy rating based on their internal testing. It requires just a few nights of sleep data to assess your risk.
I even heard a story about someone’s father getting a risk warning after using the feature, prompting them to see a doctor. While it’s not a scientific diagnosis, getting a risk indication from the ring is certainly a strong prompt to get checked out.
Workout tracking is available but seems to still be in beta mode. Currently, there are only four customizable workout modes (outdoor/indoor running, outdoor walking, outdoor cycling).
During a workout, it provides information like distance, calories burned, duration, and heart rate with a zone indicator. The app states that more diverse sports modes are coming soon, but I wouldn’t recommend buying it solely for its current workout tracking capabilities.
RingConn is also adding AI Health features, currently in beta. This includes an AI health plan tab where the AI can provide coaching, help set goals, and simplify data analysis. The goal is to make health insights more accessible, especially for casual users.
The RingConn App: Simple, Insightful, and Easy to Use
The accompanying RingConn app has a relatively simple and basic interface, it is generally easy to read and navigate. The main Insights page provides a visual “Wellness Balance” graph that quickly shows you where you’re doing well (sleep, vitals, activity, stress).
You can easily tap on any metric to dive deeper into the detailed data and analysis. There’s also a Trends tab to view average scores over weeks, months, or a year.
A useful feature is the ability to add notes and tags to your health timeline, effectively turning it into a health diary. This allows you to correlate health data with daily events or habits.
For users already invested in other health ecosystems, the app allows you to sync data to Apple Health and Google Fit. You can also share your data with other RingConn users, which I found useful for keeping tabs on family members’ health.
Home screen widgets are available and are reportedly quite good and update well, providing quick access to key stats like activity score, battery life, and steps.
One thing should be noted, creating an account is mandatory and requires you to be over 18, which isn’t explicitly stated upfront.
While you can sync data to Apple Health, some niche features like stress tracking or sleep apnea detection might not be available outside the RingConn app. Despite these small points, the app’s user-friendliness makes it accessible, especially for those new to health tracking.
Battery Life & Charging Case: RingConn Gen 2’s Biggest Advantage
This is where the RingConn Gen 2 truly excels. The battery life is exceptional, blowing many competitors out of the water.
The RingConn Gen 2 can last up to 10-12 days depending on the ring size, with larger sizes having slightly more battery. My experience confirms these long battery claims.
For the RingConn Gen 2, the included portable charging case is a game-changer. This case holds a massive amount of reserve power, providing up to 150 days (or 15-20 full ring charges for 150-200+ days total) of extra battery without needing to plug it in.
This is incredibly convenient for travel and ensures you rarely have to remember to charge the ring itself frequently. You literally only need to charge the case a couple of times a year.
The charging process itself is straightforward with the case, you simply align the ring using the internal nubs and divots. Charging seems to be relatively quick.
Price and Value: No Subscription, High-End Features at a Lower Cost
As I mentioned early on, the pricing structure is a major factor in the RingConn Gen 2’s appeal. The RingConn Gen 2 starts at $299, with different finishes increasing the price (e.g., rose gold up to $469).
Comparing this to competitors, the Oura Ring starts higher ($349+) and requires a $6/month subscription. The Samsung Galaxy Ring is $400 and, while it lacks a subscription, it works best only with Samsung phones. The Ultrahuman Ring Air also has a higher starting price ($349) and charges an annual subscription ($199/year).
The fact that you pay a one-time fee for the RingConn Gen 2 and get free, full access to all monitoring features without a monthly subscription is a huge advantage and is seen as a much more ethical business model by many.
This value proposition is so strong that I would consider the RingConn Gen 2 to be the “best value” smart ring available right now, offering top-tier features and build quality for a significantly lower total cost over time.
RingConn also offers a trade-in program where you can get value for trading in older smart rings (including Oura, Galaxy Ring, Ultrahuman), smartwatches (Galaxy Watch, Apple Watch), and even the RingConn Gen 1 towards a new Gen 2. They also offer an optional RingConn Care+ plan for accidental damage, loss, or theft coverage.
Who Should Buy the RingConn Gen 2? Best Fit Use Cases
Based on my experience, the RingConn Gen 2 seems ideally suited for several types of users:
- Those who want comprehensive health and sleep tracking but dislike wearing a smartwatch. It’s discreet and doesn’t cause distractions from notifications.
- People seeking excellent battery life who are tired of charging devices daily or every few days. The RingConn Gen 2’s charging case is especially convenient for travel.
- Users who want actionable insights from their health data without being overwhelmed by a complex app. The RingConn app is really simple to pick up and use.
- Consumers looking for the best value in the smart ring market. The lack of a subscription is a major draw.
- Individuals specifically interested in monitoring their risk of sleep apnea.
