    • Two rings failed, but RingConn ultimately stood behind the product
Color: Future Silver Size: 10
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. ... show more

    • Love it way more than my Whoop
Color: Future Silver Size: 13
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! ... show more

    • I do NOT recommend for Sleep Apnea monitoring!
Color: Matte Black Size: 8
Review Image by Jeepsjunction
Review Image by Jeepsjunction
Update: I lowered to a 1 rating. Now the battery only last 2 days before it dies. I purchased this ring because of few things. 1st. I wanted a black ring to replace my lost wedding band. 2nd my wife recently said I appeared to stop breathing a few times while I was sleeping (more on that later). 3rd I've never liked wearing a watch and I'm tired of my apple watch which I only liked for the fitness aspects. After a lot of research, I decided on the RingConn GEN2. I liked the sizing of it, and it appeared to cover my needs. I was unhappy that the original version doesn't come in black. I recommend buying the sizing kit as there are no 1/2 sizing options. I'm happy with the sizing and I'm getting use to the wear of it because of the nubs (sensors) that stick out on the inside of the ring. This doesn't appear to be an issue for me so far. I have read that some people find it uncomfortable. I like the fit. Review: Now my big issue. I have 2 of them and they are both around accuracy. I don't expect perfection, but I have an issue with the sleep apnea results. I purchased this ring while I was waiting on my Dr's appointment for sleep apnea. I received my ring wore it a few days and then start the sleep apnea study. The RingConn results were "No Abnormalities (0.9) or NO instances of sleep apnea. I repeated this test a week later and got the same results, actually a little better. All is good right? Wrong! I completed my sleep study, and not only do I have sleep apnea I'm going back to conduct another study so I can be properly fitted for a CPAP and to determine the pressure my CPAP needs to be set at. This ring does not properly test for sleep apnea in my opinion, nor in my Dr's opinion. My next issue (based on the previous issue was accuracy. I was surprised to see that I was meeting my step goals somewhat regularly as monitored by the RingConn GEN 2 (I'm not as motivated as I like to think I am). I decided to wear my apple watch for a day and the RingConn GEN 2 to compare steps. What I have learned so far is the RingConn GEN 2 is over counting steps to the tune of about a 15-20% difference between the ring and my watch. I can live with that you just need to be aware that it might not be as accurate as you think. At least it's not for me. What I do like! I do believe the SP02, time asleep, heart rate, and relaxed time all appear to work well. I think the ring looks great. I love not having to buy a plan to have access to my data! That is a great plus. I will be keeping the ring; first because my wife likes me having a wedding band again :-) Happy wife...... and I do not like wearing a watch and this ring fits the bill good enough. I trust the RingConn will continue to update the software and maybe address these issues. Lastly, I'm disappointed that you can't buy the RingConn (original) in black. It only comes in silver and gold. I would have returned this one and bought the cheaper one if that were the case. I don't recommend people buy this ring for the sleep apnea feature. Considering everything else go for it. ... show more

    • Do it! You won’t regret it.
Color: Royal Gold Size: 9
I wasn’t sure whether I was going to like wearing a Smart Ring, but I have found that I love it. It does take a few days of getting used to it on my finger. The insights provided are fantastic and without a subscription fee. Cost is reasonable for what you get. I had also looked at the Oura, but between the higher price and subscription fee, RingConn made even more sense. As an example, I knew that I probably wasn’t getting enough sleep and was slightly sleep deprived. RingConn shows me exactly how much sleep I’m getting each night, plus the quality of sleep. This incites me to go to bed a bit earlier and relax before I get to bed. I also like the other metrics, such as vitals and activity. The app is super easy to use and provides a lot of data without overwhelming me. I chose the Gen 2 over the Gen 3 because it’s smaller. I think that I wouldn’t have been as happy with the Gen 3 just because of the size, plus I don’t need the Gen 3 alerts. ... show more

Loving my ring! I ordered for my boyfriend and I and we received them in the next day. The packaging was original and as advertised. I usually wear a 6.5 in rings so I ordered up to a 7. My boyfriend I’d usually a 10 and ordered an 11. The ring seems snug at first but has turned out to be a great fit. I love everything about my ring. All of the features are awesome, especially the sleep apnea and pedometer. The app associated is easy to navigate! This even has cycle tracking and a baby prep option if you and your partner have that in mind. Most importantly it looks great! ... show more

I got my ringconn and within 3 months I had some issues with the battery not holding up. But contacted them through the customer service on their app. They send me a brand new one. Had no issue ever since. I like the accuracy of the health tracking and love the features and info you get especially tracking my period. Overall great product. Got some scratches but seems normal like any other ring honestly. I wear it everyday! ... show more

    • Exactly what I wanted, has exceeded my expectations
Color: Future Silver Size: 10
I've had a RingConn Gen 2 for almost a year now, and it is exactly what I was looking for in a fitness tracker. My old Fitbit died, and I needed something to replace it, but all of the new models are too large for my tastes. I really don't love wearing something on my wrist, so I was fascinated by the fitness rings, but I didn't want to pay a monthly subscription fee on top of the pricey tech itself just to use it. That's how I found RingConn; buy the ring, and that one time cost is all you pay, no subscription needed. I am not an elite athlete by any means. If you need extremely precise constant feedback to monitor everything with peak accuracy, then this is probably not for you. If you want something to give you a very good readout of your various health and fitness metrics (steps, sleep, heart rate, oxygen saturation, other vitals, etc) to show you how you're doing and to keep you on track, then RingConn should work just fine. It can also monitor for sleep apnea, but I do not use that particular feature, so I can't speak to it. Previously, the only down side was that it could not auto detect your workouts, but a recent firmware update (September 2025) fixed that and it works well, at least for walking; I can't speak to any other activities. Definitely use the sizing kit; my RingConn is a full size larger than my typical ring size, but it is very comfortable. Wear the sizer you think you need for a few days to make sure the thickness of the ring won't bother you. The extra thickness takes a few days to get accustomed to, but now I don't even notice it. I prefer to wear it on my middle finger rather than my index finger, and it still works great. My skin tends to react badly to cheap metal, and I am unable to wear costume jewelry of any kind without having some sort of skin reaction, but I have had zero issues with the the titanium Gen 2, and I wear it every single day. It is waterproof, so you can wash your hands with it on, though I do personally remove it to shower or wash dishes. The battery also lasts about 10 days for me (I only use "persistent connection" mode when exercising), and the charging case lasts for multiple charges. I think I've only charged the case twice in the almost year I have owned the ring. The ring can store about 24 hours worth of data at a time, so you will want to connect to the app at least once a day to ensure that you get of the information. I try to connect at least twice a day: when I wake up and before bed. Each "data download" from the ring typically takes less than 10 seconds, so it's very quick. The RingConn Gen 2 has far exceeded my expectations, and I would not hesitate to buy another one! ... show more

    • Good but Battery not great.
Color: Future Silver Size: 7
The RingConn Gen 2 Smart Ring is an ultra-lightweight, impressively thin wearable that features a sleek design and highly accurate health data tracking, though the battery performance degrades noticeably after six months of daily use. ⭐⭐⭐ Accurate Data Tracking and Comfort, but Battery Degrades Fast Over Time "I was incredibly excited to buy the RingConn Gen 2, especially since it is the first smart ring to offer a dedicated sleep apnea monitoring feature. From a design standpoint, it is a triumph. It is unbelievably thin, lightweight, and so comfortable that I completely forget I am wearing it. I have also been deeply impressed by the tracking accuracy. Unlike other wearables, the step counter is spot-on, the sleep data aligns perfectly with my actual patterns, and the heart rate monitoring is incredibly reliable even during intense workouts. Unfortunately, the longevity of the battery leaves a lot to be desired. While it initially lasted well over a week on a single charge right out of the box, the battery performance has dropped off a cliff after just six months of daily wear. I am now lucky if I get three to four days of use before needing to pop it back into the charging case. It is a beautiful piece of hardware with fantastic, dependable software tracking, but the rapid battery degradation over time is a major disappointment for a premium device." ## Product Breakdown * Ultra-Thin Form Factor: Exceptionally slim and lightweight layout that offers maximum comfort for 24/7 continuous wear. * Highly Accurate Metrics: Delivers incredibly reliable sleep stage data, heart rate tracking, and precise step counting during daily activities. * Advanced Sleep Health: Introduces specialized sleep apnea screening metrics alongside standard blood oxygen measurements. * Noticeable Battery Degradation: Standalone battery life drops significantly after six months of continuous charging cycles, requiring much more frequent recharges. Verdict: An outstanding health tracker that sets a high standard for comfort and data accuracy, but is held back by disappointing long-term battery endurance. ------------------------------ ... show more
