The Oura Ring has long been considered the gold standard for smart rings. But with the release of the RingConn Gen 2 Air at a much more wallet-friendly price, you might be wondering: is the Oura Ring 4 really $150 better?
In this comparison, we’re diving into the similarities and differences between the RingConn Gen 2 Air and Oura Ring 4, so you’ll know exactly what you gain (or give up) by saving that hundred and fifty bucks.
Key Takeaways
Both track core health metrics, but differ in materials, sizing, and overall feature depth. The RingConn Gen 2 Air is more affordable, offers longer battery life, and requires no subscription. The Oura Ring 4 supports more workout types, automatic activity detection, and advanced features like VO2 max and fertile window prediction.

Design
RingConn Gen 2 Air
The RingConn Gen 2 Air is made from stainless steel, while the Oura Ring 4 uses titanium. Titanium is lighter, stronger, and more durable, which might matter if you're planning to wear the ring 24/7 and want it to stand up to the long haul.
Still, the stainless steel on the Gen 2 Air doesn’t feel cheap at all. It’s solid and polished, though it may be more prone to small scratches over time.
When it comes to sizing, RingConn offers sizes 6-14, while Oura gives a slightly wider range from 4-15, which could be helpful for people with very small or large fingers.
As for thickness, the RingConn Gen 2 Air wins with a 2mm thin profile, compared to Oura’s 2.88mm thickness. It’s a subtle difference, but if you want the most discreet smart ring possible, the Air might feel a little more sleek.
Oura Ring 4
Weight-wise, the RingConn Gen 2 Air comes in at 2.5-4 grams, depending on your ring size. The Oura Ring 4 is slightly heavier, ranging from 3.3 to 5.2 grams, again depending on size.
Now let’s talk about looks. The RingConn Gen 2 Air comes in two finishes: Dune Gold and Galaxy Silver. The Oura Ring 4, on the other hand, offers a broader selection with Black, Silver, Stealth, Brushed Silver, Gold, and Rose Gold.
So if you're particular about matching your tech to your vibe, Oura gives you more style options, though you’ll pay for it (more on that in a bit).
Both rings are waterproof up to 10ATM, which means you can swim, shower, or sweat with them worry-free. The RingConn Gen 2 Air also carries an IP68 rating, which covers dust protection as well.
Features
Oura Ring 4
When it comes to health and fitness tracking, both rings cover the basics really well. You’ll get detailed sleep tracking (including sleep stages), stress monitoring, heart rate and SpO2 tracking, and daily activity metrics like steps, calories, and movement trends.
But the Oura Ring 4 definitely packs in more when you zoom in on the details.
For starters, Oura Ring 4 supports 40+ workout types, ranging from running and swimming to cardio and HIIT. Even better, it has automatic workout detection, so you don’t have to remember to log anything or manually start the session. It just knows.
In contrast, the RingConn Gen 2 Air currently tracks just four specific activities: outdoor running, indoor running, outdoor cycling, and outdoor walking. You have to manually start each workout in the app. RingConn has said they’ll be expanding the list of sports modes in future updates, but for now, Oura clearly leads in this area.
Oura also adds some extra features like VO2 max estimation (a solid fitness indicator) and a Symptom Radar that helps you catch early signs of illness or fatigue.
When it comes to women’s health, both rings track menstrual cycles and show where you are in your current phase. But Oura goes further, offering fertile window predictions and even labeling your chance of conception as “high” or “low.” If fertility tracking is a priority for you, that might be a game-changer. RingConn, for now, sticks to the basics.
Battery & Charging

Battery life is one area where RingConn holds its own.
The RingConn Gen 2 Air lasts up to 10 days on a full charge, while the Oura Ring 4 lasts up to 8 days. Charging times are fairly similar—up to 90 minutes for RingConn, and around 80 minutes for Oura.
So if you don’t love charging your wearables too often, RingConn gets you a couple of extra days between charges.
Pricing
Oura Ring 4
Now for the part that might make or break your decision: the price.
The RingConn Gen 2 Air is a flat US$199, no matter which finish you choose. That’s it. No extra costs. No monthly fees.
The Oura Ring 4, on the other hand, starts at US$349, and the price goes up depending on the finish:
Silver & Black: US$349
Brushed Silver & Stealth: US$399
Gold & Rose Gold: US$499
So yes, you're paying an extra $150-300 just for the ring.
But there’s more: Oura requires a subscription for full access to its features. That’s $5.99/month (or $69.99/year) if you want to see all your data, insights, and recommendations.
RingConn? No subscription. You get full access to all the features in the app, no paywalls, no upsells.

Final Thoughts
RingConn Gen 2 Air
If you're after the most premium smart ring experience—with advanced features like automatic workout detection, fertility tracking, and a broader design selection—the Oura Ring 4 absolutely delivers. But you’ll pay for it, both upfront and over time.
The RingConn Gen 2 Air may not have all the bells and whistles, but for $199 and no subscription, it nails the fundamentals. It tracks the core health metrics well, offers a thin design, and even comes with a longer lasting battery.
In the end, it comes down to priorities: If you're on a budget or want to avoid subscriptions, go with the RingConn Air. If you're all in on tracking and don’t mind paying for it, Oura Ring 4 won’t disappoint.
