## Description

RingConn Gen 2 Air Sizing Kit

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: Good pre-fit trial - Great way to see your ring size before purchase, give it a couple of days to see how your hands expand and contract due to varying temperatures to settle on your size.

When testing for the best size, make sure the sizing gauge remains tight around the base of your finger

### ⭐⭐⭐⭐ Lovely ring, battery life is questionable..
*by K***S on 18 November 2025*

Absolutely love the look of this ring, I ordered the dune gold and the colour is so pretty! The ring itself is not bulky at all and looks very sleek! (way nicer on the eye in comparison to an Oura Ring) The app is brilliant, great features and super easy to use! However my only negative with this ring is the battery life! I believe it’s advertised to last 10-12 days, whereas mine only lasts 6-7 days? Although this is still a decent amount of time, I would have liked to have got what was advertised! I am unsure whether I’ve received a faulty one as I seem to be the only one with this issue! I have had this ring for 2 weeks and it will need to be charged a 3rd time in 2 days… I will most likely have to return and see if I can get a replacement. It’s a shame as I do really love this ring other than that!
