The RingConn smart ring is lightweight, comfortable, and easy to wear all day. It tracks sleep and heart rate reliably, with especially useful sleep insights. Battery life lasts several days, which is very convenient. The app is simple and clear, though it could offer more advanced features. Overall, it’s a great value for basic health tracking in a discreet design.

I’ve been wearing this tracking ring for 5 months now, nonstop, & I LOVE IT. I really just wanted to track my sleep, my activity, & my stress throughout the day, plus I wanted to make sure I didn’t have an apnea issue. Comfort wise, RingConn is thinner than the Oura ring, & less annoying feeling (to me) than wearing an Apple watch. I get very rashy from wearing anything with nickel content - a previous Apple watch & band clasp made me rashy even. So one of the things I was concerned about was the nickel content. I’m happy to report that I have zero sensitivity or rashy response. Looks wise, I love that silicone covers in many colors are cheap to buy. It does say it’s water resistant, but I err on the side of caution & don’t soak it in water or shower with it on. But the best part: the function! This ring (with only the free app, no extra paid plan required), gave me an apnea test over multiple nights & ruled out any issues. It maps out my REM, deep sleep, light sleep, & activity every night & gives me a sleep score & total sleep time. RingConn tracks my stress & alerts me when my stress levels spike. It does take about 30-ish mins for it to alert me, but its been very helpful for me to know. It also holds its charge for almost 2 weeks, & from a very low charge fully charges back up in a little over an hour. That is FAR less frequent charging than an Apple watch needs. The most interesting thing: one day RingConn told me I had a headache COMING ON. I was confused bc I felt nothing. For 3 days, it showed this warning. Since I had only worn it for a month at the time, I thought I got a malfunctioning ring. BUT then! On the 4th day, I woke up sick! So RingConn literally warned me that I was getting sick (& was possibly contagious) before I even felt any symptom at all. I am super aware of my body, so this was amazing to me. That was the only time I have been sick since I’ve worn RingConn so I’ll be interested to see if it warns me similarly the next time I get sick. I took a chance on RingConn during black Friday, so I got a great deal on it. Even at full price, I would highly recommend this. I love mine!

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!

Battery quit charging after a few months, battery would only last an hour or so after charging attempts. I bought this ring a year ago but during my annual pilgrimage to the Sturgis Motorcycle Rally the thing failed to charge. Not built rugged enough for either the vibration or rain encountered during my ride IMHO. With that being said I am ordering another one today as the sleep info and reporting us important to ke, I do have sleep apnea and this thing works great and Is accurate IMHO, I'll just try to keep it out of the rain and not wear it on long rides, not worried about wearing it in the shower.

The measurements are quite accurate. The quality of the ring is very poor. For starters, I just don't accept fake advertising, and their pics are clearly misleading and false. The rings look so soft and mate, in all colors. Well, take a look at the pictures in the reviews. I got the silver one and it looks like cheap plastic that imitates a mirror. It's shiny and cheap. But that's not the worst of it. I have seen the pictures and people get scratches on the rings so easily, and for the golden and black colored ones, underneath that cheap paint, a silver or lighte color appears under every scratch. I guess that won't be so conspicuous on the silver ring. So yeah, looks very cheap and, I am sorry, there are many materials that are way harder than this. I don't like wearing something on my hand that is going to be full of scratches, lose the "plating" in no time, etc. I've paid a fortune for this ring, and there is no excuse for such a mediocre surface material. They brag that is titanium, well, my titanium watches are literally unscratchable. And I am also missing half sizes, since I am clearly in need of a half size, but they don't make them. I guess they don't care if people really need those half sizes (and trust me, if it's too tight, when your fingers are swollen, it's unbearable, but if it is to loose, it will be useless and will rotate). More than probably half of the potential customers can't find any right fit without half sizes, because then the ring will either be too loose or too tight. Fingers girth changes a lot! More than a size, between cold days and swollen fingers (when it's warmer or every time you wake up). To top it off, after paying 300+ dollars, I have found out that the charging case can't be purchased again. So if you ever you lose it or it malfunctions, the only "replacement" option is to purchase and use the docking station with cable, which they do sell. I mean, for real? Can't they sell separatedly charging cases? It's not like they'd need rocket science to sell them. Finally, yet another critizism: since the sensors must always be on the palm side of the finger, why on Earth these guys haven't thought of putting a little mark, protuberance or anything to know if the ring is correctly set? When the ring turns upside down it's very hard to tell, because you can only know by looking at the sensors, but they are not easy to see when you are wearing the ring. They haven't even thought about this, and apparently people scratch them in a certain spot to make a mark. I mean, I guess that, with so many unvoluntary scratches, one more big scratch done on purpose doesn't harm, right?

I first tried a cheap smart ring ($60), and while the hardware was somewhat impressive, the app was junk: not specific to the particular ring. This RingConn ring, and app, however, are the real deal! The ring is well made, its inside surface is made so that it tends to stay in place on your finger without rotating around over time. The charge lasts a very long time, and so far after about a month, the ring still works and charges perfectly. The titanium exterior apparently really does resist scratches, because mine still looks new and I wear it 24/7, except for charging. I swim daily, and wear the ring without issues, it really is waterproof. Too bad it does not have a dedicated tracker for swimming (you have to edit that into the app data after the swim session), but I also use it for walking in our neighborhood, and that dedicated function tracks accurately, in tandem with Google Maps, to show the route you walked. Sleep data is fairly accurate, though it finds REM during some of the time I was awake, which is not correct. It also has twice counted time in my recliner watching TV (before going to bed) as if I had gone to bed, but that data can be easily edited the next morning if necessary. Sleep apnea tracking is a nice touch, it says I probably have mild apnea, which is correct (it would be worse if I did not tape my mouth at night!). Vital signs seem to be accurate, it detects periods of exertion when you are working your body hard. The heart rate is correct even when the ring is wet, which was not the case with my previous cheapie. The "stress" measurement must be based on the HRV value, not sure if that is really helpful for me. I purchased a size 13 after trying sizes in the sizing kit--don't skip that step, because this ring has an unusual inner surface and you need to make sure to get a size that works on your fingers. Turns out that 13 is a handy size for me, because I can wear the ring on a choice of 3 different fingers, meaning I can switch hands when I need to. According to the AI in the app, the ring finger doesn't make any difference. Just keep in mind that none of these smart rings, including the Oura, are medical devices--that is, they are not directly measuring most of the information that they display. Instead, these readings are calculated using complex algorithms based on data obtained by the sensors in the ring, so they are really estimates and should be viewed over time, to see trends. Some readings are more accurate than others, like heart rate is more directly measured than REM, for instance. There's certainly room for improvement, but all in all, this is a good product!

I absolutely love this ring! I got this after my Galaxy ring stopped working after 6 months. And this thing is phenomenal! Health metrics are spot on. Step counter, vitals (heart, oxygen temp), and sleep tracker: all extremely accurate. The color is nice and it feels very durable. It doesn't feel like cheap plastic or like it's going to break. It definitely fits wonderfully and it is not bulky. It's supper comfortable and feels like it's not even there. Switching to the ringconn gen 2, best decision I ever made.

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.
