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.

Way better than the more mainstream competitors.
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.

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).

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.

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!

Calidad y precio
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.

Expensive toy
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.

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

Bague connectée ultra légère, spéciale santé+activité+sommeil avec une autonomie phénoménale !
Enfin une bague connectée tellement légère qu'on l'oublie au doigt et avec une autonomie phénoménale ! Avant toute chose, commander bien le kit d'essai à 1€ et faites des tests sur plusieurs jours avec les 3 doigts conseillés ; ça m'a permis de voir que seul mon annulaire gauche la supportait (le droit étant déjà pris), le majeur et l'index posant problème pour la préhension. Tout d'abord, j'ai lu quelques critiques négatives qui n'ont pas lieu d'être à mon avis. La luminosité la nuit par exemple : absolument négligeable tellement elle est ridicule si vous avez bien l'anneau sur le doigt. Autre exemple, l'absence d'indicateur pour bien positionner les capteurs : il suffit de la forcer un peu à glisser vers la paume de la main pour voir apparaitre deux points dorés qui indiquent le bon positionnement. Je la charge tous les matins lors de la douche dans son boitier, ce qui lui donne une autonomie quasi illimitée et sinon, elle ne me quitte pas une seconde. J'ai même commandé le chargeur usb-c de la marque pour conserver mon boitier chargé pour les voyages. L'application est bien pensée et les mesures semblent appropriées ; de plus, l'application (sous Android pour ma part) n'a pas besoin de tourner en permanence, la synchronisation avec l'anneau se faisant à son lancement. Je peux donc suivre ma santé, mon activité et mon sommeil à ma guise sans porter h24 une grosse montre connectée à recharger tous les deux jours maxi ! Autre point négatif à oublier : si l'anneau est dans son boitier et qu'il est ouvert, l'application indique bien les niveaux de batterie de l'anneau ET du boitier. Bref, foncez, c'est du lourd par rapport à la concurrence (qui a dit G.l.xy Ring ?) !
