## Description

Product Description

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!
Review: Great product - So far so good. Bought the ring to replace my Fitbit. The app is good and you don’t have to pay any additional subscription fees. Comfortable to wear all day and night. Impressed so far

### ⭐⭐⭐⭐⭐ Just like a regular ring with smarts.
*by D***. on 25 May 2025*

I purchased the sizing kit and held off for a week deciding whether I should buy this and so pleased I did. I have multiple smart watches which I don't wear for two reasons, I can guarantee I have to charge it when I goto sleep or it's to uncomfortable to sleep with. No issues with this due to the long battery life and I can just pop it on the little charger when I'm reading my book one morning. It is also small, no bulk like earlier models and there is very little difference between this and my ordinary ring on my other hand
