RingConn Gen 2 Sizing Kit - Size Before You Buy (Sizes 6-14)

Have you ever had a problem with something you bought ONE MONTH after the warranty expired? Have you even been BLOWN AWAY by the Amazing Customer Service for the product when they say, "No problem, we'll send you a replacement." This is EXACTLY what RingConn did for me and I wish I could give them 10 stars instead of just 5. Let's face it, $300 (at the time) was very expensive for me but I suffer from Chronic Fatigue and I need to track how much I sleep in a day. RingConn (Gen 2) was the best I could find and I loved that they last for up to 12 days between charging. After 12 1/2 months of using the ring, I noticed that I had to charge it more often until it got so bad that it didn't last a full day after charging it to 100%. Needless to say, the battery was dying and these things happen so I'm not blaming this on the quality of their products. Because it was past the warranty, I didn't have much hope, but after a quick call to their Customer Service Department and a ticket sent to their support team, I received an email saying they would be happy to replace it for me. I love the ring and I think it's the best on the market (although they do have a newer Gen 3 model). The ring itself gets 5 stars and the Customer Service gets another 5 stars!

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.

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.

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!

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!

I've used it for a couple of weeks and generally like it, it mostly does what I want. I think it is pretty accurate as to sleep apnea assessment (ahi tends to correspond with cpap machine). I like the fact that it will also show SpO2. For me, it overestimates my step count. I made two trips from my bedroom to my kitchen, and it recorded 150 steps. It also recorded 48 steps before I got out of bed. In some instances, I think it is counting my hand movement when keyboarding with steps. I have a step counter on my phone (always in my pocket and I historically think it is pretty accurate) and that tends to show about 2/3 of the steps the Ring does. I like the stress assessment. I like the HRV information. I like the sleep quality assessment. It has a decent charge life (for me that's running about 7 days). It's probably the best value for the money of the non-subscription rings, but it does have limitations (for me).

I originally purchased my ring in June of '25. I was pleased with it's performance and the free app. Most of my concern was tracking my sleep to try to get it regulated. Over time the battery life began to seriously diminish until I was needing to charge it every 2-3 days after about a year of use. I contacted RingConn for support through Amazon. I got prompt replies with clear requests for identifying information and explanation of the problem. They also gave me instructions to do sort of a diagnostic of the battery. When that clearly showed that the battery couldn't hold a charge at all, they offered an exact replacement at no cost. It took some time to get my new ring as it had to ship from China, but I am using it now and very pleased with the whole process. All of the email communication with RingConn was great and very easy to follow. Given that there was no extended warranty, I feel like the company treated me very well. I expect I'll just purchase an updated ring whenever I need to in the future.

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. ------------------------------

Étant fan de high tech et santé connecté, j’ai voulu tester les anneaux connectés pour pouvoir essayer de me dégager un peu des montres connectées et pouvoir reporter des montres classique. J’ai donc choisis et J'utilise la RingConn Gen 2 depuis près d'un an et j'en suis très satisfait. Le suivi de la santé et du sommeil est très précis, et l'application remonte énormément de métriques utiles de manière claire, complète et sans aucun abonnement payant. C'est d'ailleurs un vrai plus pour anticiper certains coups de fatigue ou maladies : j'ai eu un épisode de fièvre et la bague a été particulièrement efficace pour détecter la hausse de température.elle détecte les potentiels épisodes de migraines et nous met sous surveillance. La bague est légère et tellement confortable qu'on l'oublie vite au quotidien. Elle est aussi particulièrement robuste : je bricole beaucoup avec, elle prend pas mal d'impacts et encaisse très bien les chocs. Je me lave aussi très souvent les mains avec sans jamais prendre la peine de l'enlever, et elle résiste parfaitement. Au bout de 10 mois, j'ai eu un souci de batterie. J'ai contacté le service client : ils ont été extrêmement réactifs et m'ont renvoyé une bague neuve sans aucun chipotage. C'est très rassurant d'avoir un produit aussi complet et résistant adossé à un SAV aussi efficace. Je recommande sans hésiter !

Excellent!

Se tarda mucho en llegar y una vez que llega, te lo pruebas y dices “pues lo regreso, ahí dice que se puede” y si, se puede, pero lo que no sabes es que el envío corre por tu cuenta y amenos que quieras mandarlo por correos de México y darle la bendición, mejor olvídalo, que el envío sale más caro que el mismo producto. Ya tire el mío a la basura

Mi ha sorpreso per la coerenza dei dati e la qualità del monitoraggio dell’OSA. Trovo molto coerenti i risultati misurati con la sensazione al risveglio. Nonostante un monitoraggio intenso la batteria riesce a durare 4/5 giorni.

Primera vez que uso anillo inteligente y debo decir que me ha ayudado mucho a evaluar curvas de estrés por trabajo y ver el patrón que se repetía de acuerdo a las reuniones que tuviera. Además te va guiando en la calidad de sueño calificando día a día como se duerme. Lo recomiendo.
