I did a cross comparison of this ring with other brands and decided to purchase this one because it’s - More affordable - Ring sizing kit is cheap - No monthly fees - Tracks oxygen I am soo happy I chose ringconn. It looks great on my hand, battery lasts forever, charges super quick and accurately tracks so many metrics. It has told me things about my sleep I had never even considered. For example, my skin temperature was dropping at night preventing me from getting the best possible sleep. I wear socks now and get better sleep! It also knows your normal metrics so when something is off, it tells you right away. I don’t have sleep apnea but I had a septoplasty recently so I could not breathe well and it tracked all the times I had stopped breathing at night along with my oxygen levels. I wear it in the shower, pool, washing hands and have never had any issues with getting it wet. I love the way it looks. Some people have mentioned the other brands being too bulky or annoying but I don’t even feel it. I highly recommend this brand over the competition!

Great product. Does all the listed functions very well. Very nice looking and best of all it has NO subscriptions. The app works great on both my iPhone or Android. Tracks sleep very well. Needed customer service once and they did a good job.

I have been wanting to have a smart ring for a while, so I did research on the choices that were out there.. I was considering the OURA but I don’t like the thickness of the ring, and they also have a paid subscription. The RingConn is very light, very thin and no subscription. It gives me all the vital information and tracking that I need, and it syncs extremely well with my Apple Watch. I have been wearing it continuously since I got it, other than the few times I have to charge it and it holds a charge extremely well I get a week or more on a charge. It has become a constant fixture on my hand and I hardly even realize I’m wearing it. It has really made a difference in my activity as I can check it and see where I’m at and it’s helping track my sleep, which is also very important. When I compare the tracking to the RingConn and my Apple Watch, they’re extremely close. Highly recommend!

Gotta say, this device surprised me. The sleep apnea monitoring, all the beels and whistles in the app to display lots of stats, different graphs, explanations of what it all means, great! I couldn't figure out the steps part though. It's not tracking accurately. Shows a number far beyond what I am doing. Other than that, no complaints. Works in the pool and shower, I wear it all the time

I've had a RingConn Gen 2 for almost a year now, and it is exactly what I was looking for in a fitness tracker. My old Fitbit died, and I needed something to replace it, but all of the new models are too large for my tastes. I really don't love wearing something on my wrist, so I was fascinated by the fitness rings, but I didn't want to pay a monthly subscription fee on top of the pricey tech itself just to use it. That's how I found RingConn; buy the ring, and that one time cost is all you pay, no subscription needed. I am not an elite athlete by any means. If you need extremely precise constant feedback to monitor everything with peak accuracy, then this is probably not for you. If you want something to give you a very good readout of your various health and fitness metrics (steps, sleep, heart rate, oxygen saturation, other vitals, etc) to show you how you're doing and to keep you on track, then RingConn should work just fine. It can also monitor for sleep apnea, but I do not use that particular feature, so I can't speak to it. Previously, the only down side was that it could not auto detect your workouts, but a recent firmware update (September 2025) fixed that and it works well, at least for walking; I can't speak to any other activities. Definitely use the sizing kit; my RingConn is a full size larger than my typical ring size, but it is very comfortable. Wear the sizer you think you need for a few days to make sure the thickness of the ring won't bother you. The extra thickness takes a few days to get accustomed to, but now I don't even notice it. I prefer to wear it on my middle finger rather than my index finger, and it still works great. My skin tends to react badly to cheap metal, and I am unable to wear costume jewelry of any kind without having some sort of skin reaction, but I have had zero issues with the the titanium Gen 2, and I wear it every single day. It is waterproof, so you can wash your hands with it on, though I do personally remove it to shower or wash dishes. The battery also lasts about 10 days for me (I only use "persistent connection" mode when exercising), and the charging case lasts for multiple charges. I think I've only charged the case twice in the almost year I have owned the ring. The ring can store about 24 hours worth of data at a time, so you will want to connect to the app at least once a day to ensure that you get of the information. I try to connect at least twice a day: when I wake up and before bed. Each "data download" from the ring typically takes less than 10 seconds, so it's very quick. The RingConn Gen 2 has far exceeded my expectations, and I would not hesitate to buy another one!

Love this ring. Had a horrible sleep study, where I didn’t sleep at all, and results were normal. Years later and still having issues, got this and it shows when my issues are and exactly what they are. Can take this info to my dr. Also love it for the other health tracking data it provides. Doesn’t look to bulky on a female hand either, which is nice. Worn a few months, and no scratches or chips, still just as shiny. Stays charged for a super long time, and doesn’t take very long to charge it back up.
