Review: Prefer over Oura Ring 4 - Brought this after returning the Oura ring ceramic, fit is so much more sleek and stylish. I’ve been wearing it now for over 6 weeks and it’s like a part of me I don’t feel it- at first it felt alien so don’t worry the feeling goes away. The charge lasts 8-9 days normally - absolutely brilliant - charges quickly as well within maybe 1.5 hrs from dead to fully charged. The sleep detection is this rings super power - does a fantastic job. One thing I found is I started wearing it on my non dominant hand as it was registering steps just from hand gestures, but once I swapped it on the non dominant hand that stopped. It does learn your movement over time. Now I’ve done that it’s super accurate- I’ve compared my steps to my Apple Watch that I wear during the day and it’s pretty much spot on. It is very durable but I’ve scratched mine washing pots and pans so metal on metal is a no go. Connects super easily to the FREE app, the app also has some great features for tracking your health. Overall I’m super pleased and I think for the money it’s worth trying if your looking to be extra aware like me.
Review: The Best Subscription-Free Smart Ring! Super Thin and Comfortable - I’ve been wearing the RingConn Gen 2 Air for a couple of weeks now, and it has completely exceeded my expectations. If you are looking for a high-end health tracker but hate the idea of a monthly subscription (like Oura) or a bulky smartwatch, this is the one to get. ​Why I love it: ​Insane Battery Life: I’m getting a solid 10 days on a single charge. It’s amazing to go over a week without even thinking about the charger. ​Ultra-Thin & Light: At only 2mm thick and weighing next to nothing, I genuinely forget I’m wearing it. It’s much more comfortable for sleep tracking than any watch I’ve owned. ​No Subscription Fees: This was the dealbreaker for me. You buy the ring, and you own all your data. The app is incredibly detailed and doesn't hide your insights behind a paywall. ​Comprehensive Tracking: The AI-powered insights for sleep, heart rate, stress, and SpO2 (blood oxygen) feel very accurate. I especially love the "Sleep Insights" which help me understand my recovery. ​Durable & Waterproof: I’ve worn it in the shower and while swimming with no issues (IP68 rated). The stainless steel finish is also holding up great against scratches. ​Helpful Tips for Buyers: ​Get the Sizing Kit First: Smart ring sizes don't always match standard jewelry sizes. Use the RingConn sizing kit and wear the plastic ring for 24 hours to ensure a perfect fit (fingers swell at night!). ​Charging: It comes with a sleek magnetic charging dock. It doesn't have the "charging case" of the standard Gen 2, but since the battery lasts 10 days, the dock is perfectly fine for home use. ​App Syncing: It syncs perfectly with both Apple Health and Google Fit, which is great if you want to keep all your health data in one place. ​Bottom Line: If you want a premium, ultra-thin smart ring that tracks everything accurately without charging you a monthly fee, the Gen 2 Air is the winner. Highly recommended!

## Questions & Answers

**Q: What are the key differences between RingConn Gen 2 and Gen 2 Air?**
A: Gen 2 Air is made of titanium steel, offering a sleek, comfortable fit for everyday wear, while Gen 2 is made of titanium. Gen 2 Air covers key health tracking features, though it does not include sleep apnea monitoring.

**Q: Can I measure ring size without an official sizing kit?**
A: For the best fit, we recommend using our official sizing kit. Our smart ring uses exclusive sizing standards, different from regular rings and other brands’ smart rings. Use our dedicated tool for an accurate fit.

**Q: How do I ensure the best fit for my RingConn ring? / How to get the perfect fit size?**
A: Measure your non-dominant hand, with the kit’s protrusion facing your palm. Wear the sizing ring continuously for 24 hours (including sleep). Fingers swell in the afternoon/evening, so long-time wear helps you choose the most comfortable size.

**Q: How to judge if the ring size fits well?**
A: Fit should be snug but not painful. First Test: Fits closely with no gaps. Drop Test: Won’t slip off when your hand is down. Rotation Test: Twists gently with slight resistance.

**Q: How should I wear the ring correctly?**
A: The sensor inside the ring should be positioned on the palm side of your finger. Make sure the ring fits securely and comfortably at the base of your finger to ensure accurate data tracking.

### ⭐ Not worth the money
*by R***L on 5 September 2026*

I bought this as other not expensive brands require a monthly subscription for the app but this one doesn’t. However I ended up returning it as the tracking is awful, it tracks way more activity and steps than you’ve actually done and doesn’t recognise when you’re exercising, it tells you in the app that it thinks there’s been activity but you have to go in a write what it is you’ve done. This isn’t reliable either as mine said it picked up activity when I was actually just in the car driving to work. The app isn’t the greatest either, the recordings are basic and doesn’t give in the moment readings, you have to wear it for a period of time before it shows any recordings. The ring colour is also a lot darker than it looks on the photo, but the actually quality of the ring itself and the thickness of it was good but just not functional at all as a fitness ring.
