Happy I ordered
I’ve had this for 1/2 a day and I really like it. We will see how it/the charger holds up as I’ve seen some people say it doesn’t last as long as it should. It was so easy to set up and had like 75% battery, then only took maybe 15 mins to fully charge. App is easy to navigate and frankly looks good. I did a small work out and it’s accurate with the steps so far. My mini stepper counts as well so I compared to that. All other vital signs seem to be in line with what my normal is too. It’s comfortable, not heavy or thick. But still feels high quality, I was pleased pulling it out of the package. UPDATE: It’s been over a week and I still like it. The battery would’ve lasted just about 9 days, I charged it before it got to ~0%. Good enough for me. It charged quickly too, did some chores and it was done. I keep seeing reviews with the app being troublesome but I haven’t had any issues and I rather enjoy it. There’s a lot of information. I saw an update for it so maybe that’s the issue??? The ring has been really comfortable, I did get the sizing kit and it’s worth waiting the extra day or two. I also see people complaining about the size when this company and other smart ring companies clearly state they don’t follow regular jewelry sizing. So truly size before you buy unless you’ve owned one before. Stats are overall pretty accurate. I somewhat know what time I wake up randomly while sleeping and it does match with what the app says so I tend to believe the rest of it for sleep. I’ve counted off steps in my head and then looked at the app — if I walked 50 steps it logged 50 steps. All of my workouts have been detected, time/calories/steps, all there. Update #2: It’s been 3 months now 1/10/26 and I still love it. I even got my mom to trade her Fitbit for one and she loves it. Maybe I got lucky but I haven’t really noticed a difference in my battery levels, even with the ring tracking more and more things 24/7. The only thing I do is not let it get to 0% it’s not really great for any battery to my knowledge. I’ve done multiple updates for the ring and app, no issues. I’ve only enjoyed the new features. Tracking still works, workouts are still detected and everything. Also, I hardly take it off and it’s less scratched than I thought honestly, and I’m not careful. Overall, still 5 stars, still happy I ordered, still loving it.

Perfect ring and perfect price and no subscription!!!
First, make sure you purchase the ring size kit. Its like a $1.97 and when your done you can return it. I did a lot of research on smart rings and this one and its sister ring came out to be the best option for price and functionality. And the best part is you don't need a subscription!!! It was easy to set up with the app. I have apple products, and it is fully compatible with iPhone and apple health. The ring is lasting about 9-10 days on a full charge and it will notify you on phone when its time to charge. The product is also durable based on my use. It does scratch (on the bottom more but that's expected) I am also rough on it. I also keep it on while in the pool and ocean with no issues as its waterproof. I love that it tracks activity and best of all the sleep tracking. I hate wearing my ultra watch3 to bed so this is perfect. And it looks like its accurate with the data. I couldn't be happier, I will buy another if and when this one kicks the can or they update the current version.

FREE APP and Comfortable
First let me say, FREE APP. Nothing additional is needed unless you want it. Compatible with my iPhone 14 and was setup within minutes. I brought this to monitor my sleep and heart rate as it is more comfy to wear a ring sleeping than a watch. It takes about 4 days to know a bit about you to track patterns. But once it tracks it will tell you everything you need to know. The sleep monitor is accurate, to the points it picks up on my lack of sleep, when I nap on the couch and wake up to move to bed. I’ve worn this for over 2 weeks now and I absolutely believe it is worth the money. The stress levels are insanely accurate, as I wear it during work and through some stressful life moments and it lets me know. I brought without the sizing kit because I already knew my ring size and it fits like a regular ring for me. I do have slim fingers.

I have had my RingConn Gen 2 Air for a month now and I absolutely love it. I ordered the sizing kit prior to placing my order for the actual ring. Sizing kit rings are true to size. Honestly, the ring looks and feels high quality. I am able to wear my ring 24/7 no complaints. The battery lasts about 9 days and the data is fairly accurate! Connecting to my phone is very easy. The ring gives you great feedback on your data and sends your phone reminders if you are stationary for too long or if there is an abnormality noticed. So far 10/10! I recommend it to my friends and family. Only thing to note is the ring can scratch. If you take care of the ring, the scratches are minimal.
