I LOVE this ring!
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!

Great ring, yes it's a little pricey, but it works like it is supposed to!
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!

Game Changer for Sleep Apnea & Daily Activity
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!

Finish rubs off VERY quickly, fitness tracking WAY off - sleep tracking pretty good
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).

No Subscription Required, But a New Update Removed All Functionality from the device.
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.

A Lifesaver!
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.

Useful data that is reliable up to a point
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.

RingConn is Great!!!
I have both the RingConn and the Ultrahuman Ring Air simply because a monthly subscription is not justifiable based on the price and due to the fact Oura already corners 80% of the market on wearable tech rings. Both the RingConn and the Ultrahuman Ring Air are excellent products but the Ultrahuman battery life lasts about two days while the RingConn easily lasts about a week or more between charges. Ultrahuman Ring Air has a more polished app and provides better explanations about the readings and gives good advice to improve your metrics, however it is currently not available in the US due to pending litigation brought by Oura who clearly wants to corner the market. Go with RingConn if you hate subscriptions. You won’t be disappointed!

RingConn Gen 2 Smart Ring
Ich habe mir 3 verschiedene Smartringe angesehen. Alle hatten unterschiedliche Größen. Also, man kann nicht eine Firma probieren und sich dann doch für eine andere entscheiden. Das geht schief!!! Ich habe jeweils den Ringfinger und Zeigefinger rechts und links getestet und mich dann für den RingConn entschieden, weil die Größen einfach besser auf meine Finger passten. Wichtige Voraussetzung war auch, dass nur dieser Ring die Schlafapnoe überwacht. Und das macht er eindrucksvoll. Die Werte kann ich in der App abrufen, diese ist übrigens kostenlos. Es dauert ungefähr eine Woche, bis die Daten umfangreich ausgewertet werden können. Aber vom ersten Tag an wurden die Werte bereitgestellt. Wichtig für mich ist die Schlafüberwachung und das ist eindrucksvoll.

Si lo quieres para medir y devolver, olvídalo
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
