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 been using the RingConn Gen 2 for a while now, and it has become an essential part of my daily routine. As someone managing sleep apnea, the level of detail this ring provides is incredible. It tracks my AHI (Apnea-Hypopnea Index) and blood oxygen levels throughout the night, which gives me peace of mind and real data I can actually use to monitor my health. What I love: • Sleep Tracking: The sleep apnea monitoring is top-notch. It even flagged a significant oxygen drop for me, which really helps in understanding my sleep quality. • Step Counting: It’s surprisingly accurate with steps. I’ve compared it to other trackers, and it holds its own perfectly. • Comfort: It's lightweight and comfortable enough to wear all day and night without irritation. The Trade-off: The only thing to keep in mind is the battery life. While it’s rated for longer, using it as a dedicated sleep apnea and oxygen tracker means the battery drains a bit faster—I usually get about 7 days out of it. Honestly, for the amount of vital data it’s pulling while I sleep, that’s a trade-off I’m more than happy to make. If you’re looking for a discreet, powerful way to track your health and sleep, I can’t recommend this enough!

This is a great smart to track a variety of vitals. I specifically needed a smart ring that would measure my blood oxygen and track sleep apnea events and hypoxia. Not many rings can do that but this one can. Well worth the money, I have it on all the time, and I work as a mailman, so I'm on there in all elements wearing this, in the shower, at work, asleep, still works perfectly. I couldn't be happier and I daresay this product helped save my life. I ended up getting a cpap because it confirmed I had severe sleep apnea. Tracks your steps, heart rate, blood oxygen, kcals burned, sleep quality, stress levels (although the stress level accuracy I don't think is very accurate). I switched from the fitbit to this, comfortable lightweight and has a long battery. BE SURE to FIRST GET THE RingConn sizer. Itll be a box with a bunch of different size plastic rings. Its important because the girth of your finger changes throughout the day and its important to find one that fits well and is comfortable for all day use.

So...here's the thing. What you'll think about this ring depends on what you bought it for. Sleep tracking? Decent. Close enough to get a good idea of what your sleep looks like. Fitness tracking? Not even close - typically 2-3k steps more recorded than on my apple watch - and I trust the watch more since it has GPS In addition, the whole idea of a 'smart ring' is to wear it all the time...well...after wearing it to the gym and doing dumbbell presses, the black finish is already scratching off...kind of a big issue considering what this wearable was made to do. The app itself is pretty straight forward and the ring, when sized correctly, fits fairly comfortably. I do notice that my index finger gets irritated every few days - but it also fits my middle finger so I just switch over for a day or two. Battery life seems to be pretty decent - I've been able to wear the ring for a week straight with no issue. Very important: do not order your normal ring size as Ringconn has their own sizing. You need to buy a sizing guide (it's like 2 dollars, no big deal) to check your size. As an example I am a 8.5 normally, in ringconn I'm a 12 (index finger).

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.

I’ve been very pleased with the RingCon. It’s lightweight, comfortable to wear all day and night, and the battery life is outstanding compared to many other wearable devices. The sleep, activity, and wellness tracking features provide useful insights without requiring a bulky smartwatch. The app is easy to navigate, and the ring feels durable and well-made. Overall, it’s a great option for anyone looking for a discreet and convenient way to monitor their health and fitness.

I've had it almost a year now and have been very impressed with it. it keeps track of almost every thing my Apple Watch does, and no subscription. It's also very nice looking and easy to sleep with. I also have to rave about the customer service, last month it started not holding a charge and I contacted them and they replaced the ring. I was very impressed with the customer service! Highly recommend. They upgrade the app periodically and add new features, which is nice but sometimes takes a little getting used to.

I purchased the ring sizer first and I ordered a size larger based on reviews. The ring is still a little tight even sizing up. I lost the ring within 24hrs of getting it and was able to find it in the yard with the GPS, find my ring feature. The sleep tracking is ok, it’s not super accurate. And the step count is always 1000 steps off from my Apple Watch (usually more steps than my watch). It does not integrate with Apple at all. I like there is no monthly fee. There are a lot of neat features to the ring, but not sure how accurate they are. I have had this ring several months and I have scratched the finish on the inside of my finger but the otter side is fine and purchased the black matte color. I am concerned about long term durability as I have had reports of battery issues and short battery longevity. As for now, the battery last about a week and I like the portability of the charger case. If I had the opportunity to purchase this ring or the Oura ring, I would probably choose Oura due to reports of it being more accurate and better sleep technology and ability to integrate with Apple health. Other than that, they have the same features.
