Thinking about joining the smart ring club but not sure which one to pick? RingConn Gen 2 Air and Oura Ring Gen 3 are two of the top contenders, each offering a sleek design, powerful health tracking features, and daily insights that go beyond steps and calories.
But they’re not built the same, and you may want to know exactly what sets them apart before making the call. Let’s break it all down, from design and features to pricing and battery life.
Key Takeaways
RingConn Gen 2 Air and Oura Ring Gen 3 both track essential health metrics, but they differ in features, design, and pricing. RingConn offers longer battery life, no subscription, and a lightweight build. Oura provides more activity tracking, advanced insights, and style options, but requires a monthly subscription for full access.

Design

Let’s start with how these rings look and feel, because let’s be honest, if you’re wearing something 24/7, it better looks good.
RingConn Gen 2 Air comes in just one style with a clean, squircle design. It’s made from stainless steel on the outside and resin on the inside, which helps keep it lightweight and comfortable. You’ve got two color options: Dune Gold or Galaxy Silver.
Oura Ring Gen 3, on the other hand, gives you a bit more variety in both form and finish. It comes in two styles: Heritage, which has a slightly raised plateau, and Horizon, which offers a completely smooth, flat look. The materials are also a touch more premium—titanium exterior with an epoxy interior.
When it comes to size, RingConn covers sizes 6-14, while Oura goes from 6-13. Thickness-wise, RingConn is slimmer at 2 mm compared to Oura’s 2.77 mm (Heritage) and 2.9 mm (Horizon).
The RingConn Gen 2 Air is also the lighter option, weighing between 2.5 to 4 grams depending on size, while the Oura Ring Gen 3 ranges from 4 to 6 grams.
Both are swim-friendly with 10 ATM water resistance, but RingConn adds IP68 protection too.
Features
Oura Ring Gen 3
Both rings nail the basics when it comes to health tracking—think sleep stages, heart rate, stress levels, blood oxygen, and daily activity like steps and calories. But dig a little deeper and you’ll spot some differences.
Oura Ring Gen 3 has a wider scope of fitness tracking with over 40 supported activities—from jogging and cycling to yoga and even housework. It also comes with automatic activity detection, so you don't have to manually start a workout.
RingConn Gen 2 Air is more limited in this area. It currently supports just four types of activities: outdoor running, indoor running, outdoor cycling, and outdoor walking. You also have to start workouts manually through the app. RingConn says they’re working on adding more sports modes in future updates, but for now, it’s pretty basic.
Oura also goes a step further with features like Cardio Capacity (which estimates your VO2 max) and Symptom Radar, which helps you catch early signs of illness or fatigue.
There are some noticeable differences in women’s health tracking too. Both rings offer period predictions and show your current menstrual phase. But only Oura provides fertile window predictions and labels your chance of conception as "high" or "low"—features RingConn Gen 2 Air doesn’t offer.
Battery & Charging

When it comes to battery life, RingConn takes the win.
Its battery capacity ranges from 12-15 mAh depending on ring size, and you can expect up to 10 days of battery life. Charging takes around 90 minutes.
Oura Ring Gen 3 has a slightly larger battery (15-22 mAh), but due to the more advanced sensors and features, it lasts up to 7 days on a full charge. Charging is a bit quicker though—about 80 minutes.
Pricing
Oura Ring Gen 3
RingConn Gen 2 Air keeps things simple: US$199, no matter which size or finish you choose. Plus, there’s no subscription required, so once you buy the ring, you’re all set.
Oura Ring Gen 3 is a bit more complicated. The price varies depending on the style and finishes you select:
- Silver & Black Heritage: US$299
- Stealth Heritage: US$349
- Gold Heritage: US$449
- Black Horizon: US$299
- Stealth & Brushed Titanium Horizon: US$349
- Gold Horizon: US$449
The good news is that as of May 2025, the prices have dropped. Most variants are still more expensive than the RingConn Gen 2 Air, but the Silver & Black Heritage options are now US$199—the same as RingConn Gen 2 Air.
But remember, on top of the upfront cost, Oura requires you to pay a monthly subscription fee of US$5.99 (or US$69.99/year) to unlock all of Oura's features. Without it, the ring becomes a lot less useful.
Therefore, the RingConn Gen 2 Air still emerges as the more cost-effective option in the long run.

Final Thoughts
RingConn Gen 2 Air
Both smart rings offer impressive health insights packed into tiny, stylish packages, but they cater to slightly different users.

Choose Oura Ring Gen 3 if you want deeper health insights, automatic workout detection, and more premium finishes to match your style. Just keep in mind that you’ll be paying more upfront, and again each month for the subscription.
