I’ve been using the RingConn Gen 2 for about six months now, and I absolutely love it. The features are fantastic, and the app is super intuitive and easy to use on a daily basis. The sleep tracking is especially impressive, and the wide range of body metrics it provides has been incredibly helpful for understanding how my body is doing overall. I also really appreciate how frequently the developers update the app and continue to add and improve features. I wear the ring every single day, including at work, and it still looks brand new with no scratches at all. The battery life lasts exactly as advertised, and charging is incredibly fast, making it effortless to keep it ready to go. Highly recommended!

Just got my RingConn 2, and so far, I’m really impressed! I went with the gold, and it’s a gorgeous color that matches my other jewelry perfectly. The ring fits snugly and comfortably—I got a size 9 for my index finger. I also really like the portable charging case; it’s sturdy and convenient. I charge it while I shower, and it’s ready by the time I’m done. I’ve only let it get down to about 70%, so I can’t say how long it would take from a completely dead battery. The app is super user-friendly, and I love the sleep tracking feature—it seems accurate, and I look forward to checking my sleep score each morning. I haven’t compared steps or other metrics to my Apple Watch yet, but I plan to and will update my review later regarding accuracy. No scratches yet, but it’s new, so I’ll see how it holds up over time. From what I’ve seen from other users, I’m fully expecting some wear and tear eventually. What I really like: no subscription required, sleek design, and easy daily use. So far, it feels like a solid investment for anyone looking for a smart ring that’s both functional and stylish.

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 really like the data this ring gives me. I deducted a star for the app. The app doesn't distinguish or allow you to edit for overnight wake ups and keeps overwriting the wake up time it does let me edit. there is no detailed data export so that's also not the greatest. overall. having this for only a few weeks I'm very happy with it. and glad it works without a subscription. on pure aesthetics. I like the way the silver looks on my finger. The ring is very light. not sure about durability yet but hopeful I get a few years out of it.

The RingConn Gen 2 does what it’s supposed to do. It provides basic medical stats, and does so without a monthly subscription fee like the more well known health ring. It is also very easy to link and set up. The app is very intuitive and easy to navigate. I selected RingConn primarily because it provides data on your sleep, including sleep apnea statistics, which the other rings don’t. The ring is comfortable to wear and is much lighter than I expected. You barely know it’s on. It’s also not as wide as its competitor. I recommend ordering the ring sizer kit first. The sizing is not the same as a traditional ring. Also, the silver version is very high gloss, like chrome. I originallky ordered the silver ring, but then did a return and got the black one instead. The black has a flat or satin finish. I like that much better, but it’s all about what appeals to you personally. I am very happy with the RingConn Gen 2, the info it provides, how quickly it charges, and that you get your data without having to pay a subscription fee or have your personal information uploaded to the web.
