Perfect ring and perfect price and no subscription!!!

joshua s.December 31, 2025

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. Read more

Happy I ordered

DanielleOctober 10, 2025

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. Read more

Been using for 3 months

Reviewer 03December 5, 2025

so I’ve been using us through three months. It works so well, I was a little hesitant because it’s a lot cheaper than other options. The app has no subscription, is so detailed and has already updated since I had it and it’s even better than when I originally got it. It fits true size, super easy to use, battery last about nine days and takes like 20 mins to charge to full battery! I use my hands a lot so I would say it’s very durable, no issues in water, when using cleaning products. It’s kept its color, no glitched. I highly recommend getting this and not spending $500 on a different ring especially if you’re new to this sort of Technology. Read more

Everyday Wear

DevinJune 11, 2025

Wasn’t sure what to expect from this thing but gave it a shot. I wear it everyday now and can say I mostly enjoy it. I like knowing how I slept the night before and keeping track of my steps here and there. It charges super fast too and rarely needs charging honestly. Waterproof tested- I’ve gone to the beach, been in the pool, the shower, no problems. I will say I don’t love how it makes my finger feel after wearing it for a while but I just switch fingers and let the other one air out and I’m good to go. Sizing wise I just measured my finger with a tape measure and checked it against a ring size I found on google and it was accurate. It does scratch pretty easy but overall holds up well. My only complaint is that the step counter seems to be somewhat inaccurate. Often times it’ll say I’ve walked 100 steps before I ever get out of bed. Or one time on a 2 hour road trip it said I walked 2000 steps. I presume it was counting bumps? No clue but way off for that day. Read more

Nice mid-priced ring. Comfortable, decent app. (So far, free app, but read details)

LuckyFeatherSeptember 28, 2025

I love the health details on the RingConn App. It has about everything I could possibly want, except Blood Pressure, which I am not sure rings can do. The font on the app is a little hard to read as it is small and they use gray instead of black in most of the text. I only have an iPhone10, so maybe a larger phone would be easier to read. The data collected is accurate though, compared to the cheaper $40 health tracker rings. A HUGE PLUS is that there is no monthly charge to see your own data and use the app, like the Oura ring does. Monthly digs into your pocket really add up. After paying $200 for something, you shouldn’t have to pay to see your own health data. I did however notice they say for “Basic information”, but for more details, it cost $? I haven’t been charged, or have seen any adds yet, in the week I have worn it, so we will see. The RingConn is comfortable and well made. The outer titanium surface (I have galaxy silver) is very durable, but I still cover it with a clear ring protector. The bumps inside, compared to a normal ring are unnoticeable. They do help to keep the ring in the correct position. I have had an issue with sizing, like others have mentioned. I even bought the RingConn sizing kit. According to the ring sizing kit, my index finger, normally a 10, needed an 11 RingConn. When I recieved the 11 ring, it was slightly larger, by about a half size. Had to return for a 10. I sure hope they give me my money back. We will see. One thing I do wish the charging stand had was a battery in it with a cover to keep the dust off, like others rings have. Would be nice for travel. Also, there is no fully charged light. You need to look at the app to see the percentage charged. But this wouldn’t keep me from buying it. I will update my review, as time goes on to keep you informed. Read more
