Review: Two rings failed, but RingConn ultimately stood behind the product - I am revising my original review because RingConn ultimately provided me with a second replacement ring, even though my original warranty period had already expired. I purchased my RingConn in February 2025. Within the first year, the original ring developed a serious battery issue and would discharge within approximately 1.5 to 2 hours. After troubleshooting with RingConn support, they replaced it with a brand-new ring. Unfortunately, that replacement later developed essentially the same problem. Once removed from the charger, it would discharge within a few hours and die. At that point, I was understandably very frustrated. Two separate rings had failed, including the brand-new warranty replacement, and I no longer had much confidence in the hardware reliability. However, I want to give RingConn credit for how they ultimately handled it. Even though they initially told me the order was outside the refund period and warranty, after reviewing the repeated battery failure they agreed to send me another new replacement ring at no cost. So my experience has been mixed. When the product works, I genuinely like it. The app UI is excellent, the tracking and data are useful, and the overall functionality is very well designed. It is one of the better wearable experiences I have used from a software standpoint. My concern remains long-term hardware reliability. Having two rings develop similar battery failures is difficult to ignore. At the same time, RingConn did ultimately stand behind the product and replaced the second failed unit even though the original warranty had expired, which I think is worth acknowledging. I am now using the second replacement and will update this review again if anything changes. Excellent software and functionality. Questionable hardware reliability in my experience, but very good customer support in ultimately resolving the issue.
Review: Love it way more than my Whoop - I switched from a Whoop, in part because it still wasn't totally comfortable sleeping with it on, and because the annual subscription was so expensive... 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!

### ⭐ No Subscription Required, But a New Update Removed All Functionality from the device.
*by B***E on December 31, 2025*

Edit: Beware- Do Not Waste your Money! I ended up liking this device more than I first suspected. I got used to using the rings and found the sleep and other data easy to understand and correlate. I had decided to edit my review and give it 5 stars, despite the difficulties with the ring not accommodating my wheelchair use. That is, until yesterday. For some reason, the developers released an update that removed everything I loved about the device and replaced it with nothing useful. You can no longer tell when you were asleep or awake; there are no sleep-stage data graphs, and the graphic representation of movement disappeared as well. The smart ring became stupid with the speed of an update. I've sent feedback to the developer, but I don't expect a reasonable reply. I don't know why they removed all functionality from what was an excellent smart ring with easy-to-understand graphs and no subscription fees. As far as I can tell, they haven't added a subscription fee yet, but they've trashed the usefulness of a good device and replaced it with nothing. I wouldn't recommend this smart ring to anyone as it is currently non-functional. Hopefully, enough people will provide feedback, and the developers will consider returning the ring’s original functions and graphs. Pros I like the fit, color, and look of this smart ring. I did order the sizing kit. I suggest that anyone contemplating purchasing this ring try on the different sizes. I would have ordered the wrong size had I not tried the sizing kit first. It's more comfortable than I had expected. I am not used to wearing rings, and I expected it to be bulky and annoying, but a few hours after putting it on, I forgot it was there. I really like that there’s no subscription. The ring does an adequate job of monitoring sleep, heart rate, O2, and most other measurements. The battery life appears to be as advertised, which is a plus. I've found that most electronic devices advertise longer battery life than my experience shows, so it's refreshing to see that the developers of this device were honest in their advertising. I appreciate this, as I rarely encounter it in practice. Cons However, it has difficulty deciding how to categorize exercise. I am disabled and wheelchair bound. Apparently, there is no way to inform the program of this fact, which has it misunderstand my activity level. I would like to see an option added to the programming to accommodate people with physical disabilities, including those who use mobility devices such as canes, walkers, and wheelchairs. The most annoying thing about the app, however, is that the date is off by 1 day. I want a way to manually set the date, since it doesn't automatically adjust to the correct date. Another thing that slightly bothers me is that the sleep reports aren't as detailed as those from an Apple Watch or a Fitbit. I assume that’s because there's no subscription, but I could be wrong. Overall, there would need to be significant changes to earn more stars in my review. I haven't tried other smart rings, except for an inexpensive one I purchased some time ago that had a very short battery life and wasn't comparable to today’s smart rings. If the developers fixed the few issues I had with this ring, I would recommend it without reservation. But since I haven't tested it against the competition, I can say it's worth looking into for now. The time between charges is impressive, and it does have the benefit of no subscription fee. These two things alone make it worth looking into.
