I was originally waiting for the Ringconn Gen 3 to come out, but then I lost my Whoop charger on a plane, so I ended up grabbing the Gen 2... So happy I did! I may upgrade later, but honestly, the Ringconn Gen 2 is ticking all my boxes so far. It's super comfortable to wear, I normally wear it on my middle finger of my right hand (I'm left handed) but it also fits perfectly on my index finger, so I can switch it over if I get that soft soggy white ring rash, and just wear it for a few days on the other finger. The battery life is great, I just got into a routine of charging it on a Sunday afternoon while I'm chilling, and it only takes an hour or so to fully charge. It still has a few days charge left if I'm busy and don't get to do it on a Sunday, but I like the routine. I wear an Apple Watch Ultra for most of my fitness tracking, but the Rigconn actually picks up those short duration activities that the Apple Watch doesn't... spend 20-30 mins mixing and laying concrete or doing yard work, and Ringconn picks it up, while the Apple Watch typically won't. I also like that it's measuring the morning light exposure during the first hour after wake up... this one surprised me, but it's actually using it's sensors to detect the intensity and color of the light after you wake up... getting natural sunlight after you wake up helps depress melatonin production and improves wakefulness... it gives you a running measure of your wake up light exposure and differentiates between natural and artificial light! The app seems to be constantly improving. This was the one perceived weakness with Ringconn, but I can honestly say that I have seen clear signs that they are actively developing the app in the right direction, and also that they have been extremely responsive to user feedback... the responses to questions and feedback have been way more than canned or AI generated replies, they truly seem to welcome and respond to feedback. I love the no subscription model, and that they openly share data with Apple Health so it drives other apps as well if I want more specialized focus, but honestly, I think they are quietly building out their app in all the right areas, and I'm loving the platform. I have friends with other devices, and the Ringconn seems generally more compact and wearable than most I've seen. I'm so glad I switched, and I won't feel bad if I invest later in the Gen 3, but I don't feel like I'm missing anything now, so it will be because it offers something else I want, not because it fixes a gap in the current iteration! Review: Useful data that is reliable up to a point - My sense is that with RingCon versus the alternative that requires paying a monthly fee for service, is that RingCon is more than good enough to avoid paying a monthly fee. That said with all of the ring based solutions they are best used for everything except exercise. For that you really want something that fits as a band on your wrist to obtain accurate exercise data. But if you are looking for sleep data then RingCon certainly works very good for this purpose. Monitoring through the day also is good though if you are constantly having to remove the ring because of something you are doing with your hands, perhaps this might not be the best solution. One fear based upon reading on the Internet is battery longevity. The Internet suggests that the ring's battery will loose the ability to hold a charge in a year's time. Likely this could be because of the very small battery embedded in the ring is worked hard and over a year time gives up. The battery is not replaceable given it is encased in epoxy that seals the ring such that you can wash with the ring on. Apparently there is a trade in option and I believe the cost is $100. Which suggests that the long term cost of using the ring is not a usage fee, but $10/month given the battery wears out. Likely the competition isn't saying this such that their cost of operation is their monthly fee plus whatever it costs to replace their ring in a year or so... Would I buy this again? I want to say no. I found that after a month I learned all I needed from the data and the data wasn't changing. In the end it cost me the price of the ring to learn to solve why I wasn't getting a good night's sleep. Though it could be said that the ring's cost was cheap if that is the case. ## Features - [Size Before You Buy] Before purchasing the RingConn Smart Ring, we highly recommend acquiring the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger.

It's lightweight, comfortable enough to wear all day and night, and provides an incredible amount of health information in such a small device. The sleep tracking, heart rate monitoring, stress insights, and battery life have all exceeded my expectations. One of the biggest advantages is that there are no ongoing app subscription fees. It's refreshing to buy a smart device and have full access to the features without paying a monthly charge. The battery lasts much longer than most wearable devices I've used, and the companion app is easy to navigate and provides clear, useful data. If you're looking for a discreet, comfortable, and feature-packed smart ring with outstanding battery life, this is an easy five-star recommendation. ## Frequently Bought Together - RingConn Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Only Smart Ring - ULTRAHUMAN AIR-Smart Ring Health Tracker, Sleep & Fitness Tracker, Smart Ring for Men/Women, Size First Sizing Kit - Oura Ring 4 Sizing Kit - Size Before You Buy Oura Ring 4 - Unique Sizing - Receive Credit for Purchase --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/691271246-ringconn-gen-2-sizing-kit-size-before-you-buy-sizes](https://www.desertcart.ie/products/691271246-ringconn-gen-2-sizing-kit-size-before-you-buy-sizes) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-08-06*
