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!

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.

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.

Definitely worth considering
To start, I want to say I don’t regret this purchase at all. I’m pretty neutral when it comes to the RingConn fitness tracking device. A lot of what I don’t like are probably issues one would run into with any ring style tracker. First impressions: The RingConn ring was packaged very nicely. The charging case feels really solid and the ring stays secure on the charging post. The ring itself is very lightweight and I’m fine with that. I feel like a solid metal ring large enough to accommodate the sensors would be a little too heavy for my taste. Overall, the fit is true to the sizing kit (definitely recommend buying this to test your size) and it’s very comfortable to wear casually and during exercise. Sync features: the setup process was super quick and easy. The ring syncs with the app whenever the app is opened and it does so fairly quick. The app also syncs with my other health apps very easily. Tracking: the tracking is where I’m a little less impressed and I think the majority of what I’m not content with will be common across ring style trackers. The ring seems to track lower on all metrics compared to my Apple Watch. It also tracks distances that are typically 0.25 mile less than my treadmill readouts. I’m a casual runner and don’t use any advanced methods to track my distance and other metrics so I’m not sure which is accurate. Just something to be aware of. That aside, I do like the sleep tracking feature. My Apple Watch battery barely lasts a day so using it to monitor my sleep is not feasible. This ring has a battery life of ~12 days and is very comfortable to wear overnight, so I do appreciate the sleep monitoring. I typically avoid wearing this during the shower or other instances where it would be exposed to a lot of water so I’m not sure how the water resistance is. I can say that sweat during workouts haven’t seemed to effect the functionality. App: the app is really nice. The verbiage is kind of odd, so you can tell it’s been translated to English but it’s still easy to understand. It integrates with my other health apps very easily so that’s a huge plus. And most importantly, there is NO subscription fee that is required to have access to the full functionality of the app. Overall, I’d say if you’re interested in this style fitness tracker, then this is worth checking out. I’m glad I bought this instead of a the much more expensive alternative.

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!

Had high hopes for this ring.
After giving this smart ring a good chance I’ve decided to return. After doing a lot of research comparing competitors I really thought I made the best choice. This ring needing no subscriptions was a huge plus and the battery able to last up to 12 days, amazing. I wore thing ring for about a month, 24/7. Great gold color, durable. Easily to turn on/install. Was easy to get used to on my hand and the battery did last a long time. Charging case is sturdy and holds a charge itself. So if you go on a trip you only need the case, no cords. When it comes to the main reasons I wanted a smart ring, get to know my body better, track my stress and most importantly monthly cycle. While wearing the ring I found out I was pregnant. I let the ring know I was no longer trying to conceive and the ring basically told me “we’ll see ya in 9 months” I was shocked it wasn’t going to offer any information for my pregnancy journey. Not even a weekly update. Huge let down. I still wanted to keep wearing the ring and utilizing other benefits. Today, I fainted. Literally passed out. The ring had NO IDEA. Didn’t warm me something was off and after had no recollection of it happening at all. I’m returning the ring.

Beeindruckend genaue Bewegungs- und Schlaferfassung
Richtig getragen liefert der RingConn Gen 2 eine beeindruckende Genauigkeit in der Erfassung von Bewegung und Schlaf. Die Apnoe-Überwachung funktioniert mit plausibel erscheinenden Analysen. Ein Beleg der Werte ist letzten Endes nur durch medizinischen Abgleich möglich. Um über diesen Schritt in ein Schlaflabor und weitere Maßnahmen zu entscheiden, liefert er ein sehr gutes Tracking. Über Varianten der verschiedenen Sportarten kann ich nichts sagen, für mich ist der Alltag entscheidend. Dafür klare Empfehlung, in Roségold ein schöner Hingucker für Frauen. Das Tragen ist angenehm, die wenigen Minuten für den Datenabgleich sollten für jeden möglich sein. Der Akku ist topp.

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 ?) !

Excellent Product and Value for money
First check the best fit of ring size using the size kit. Writing this review after 45 days, Looks elegant, works excellent, Battery Remains 10 days, Perfectly syncs with the phone. Don't feeling wearing it. App is too professional and provides loads of information on the Vitals, Sleep, Activity and Stress. Ai based plan needs a lot of improvement (still in beta), finding cumulative monthly achievements in the app is bit hard. Sometimes the info provided by app seems to be overwhelming. Sleep Apnea Tracking is good and looks suggestive. Only after couple of months it can be confirmed. Otherwise a best product that comes without any subscription and doing it's job so well. Kudoos to Ringconn Team.
