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.

Best smart ring ever — super comfortable! ⭐⭐⭐⭐⭐
This smart ring is amazing. It’s incredibly comfortable to wear— even to sleep. Fit tip: It runs a bit smaller than usual. I normally wear a size 5, but ordered a size 6, and it fit perfectly. What I love about it: • Tracks wellness balance data including sleep, vitals, activity, menstrual cycle, relax status, and lifestyle score • No monthly subscription required — you get full features right away • Battery life is great — I recharge it every day in the shower and it never drops below 50% before I recharge Highly recommend if you want a comfortable, capable smart ring without ongoing fees!

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.

Go read the reviews for the App itself! Don't make my mistake!
I chose this ring over its more expensive competitor solely because reviewers here claimed the app was intuitive, informative and user friendly. To say I was shocked to discover none of those things were true would be an understatement. Fact of the matter is the app is not user friendly in the slightest and what little settings it has for you to customize don't even work! For example, I unchecked 24-Hour Clock which should have defaulted all clock settings and time reading displays within the app to 12-Hour format, right? Well, it does not! Unchecked or not, the app knows no other alternative - it only knows, operates from and displays the time in 24-Hour format! I highly recommend taking a look at the reviews for this app in the iOS AppStore because it's what I didn't do but should've done prior to purchasing. I let the reviews here sway me when I should've gone to the source. And boy, are the App reviews telling. One of the reoccurring "cons" stated in reviews here about the competitor ring is that their app requires a monthly subscription fee to use. This "con" was very effective in making this ring look like the more appealing option - even more so because the competitor ring AND its ring sample kit are already priced higher than this ring, so naturally one would be paying a lot more for that ring not just upfront but longterm. This ring being the cheaper - the actual ring itself as well as its ring sizing kit - of the two with a subscription-free app to boot would no doubt seem like the better buy! Obviously I didn't buy the other ring so I can't tell you if that ring is what it claims to be or if its $5 monthly subscription fee is worth it, but what I can tell you is the free-of-charge $0 app for this ring is so awful you couldn't pay me to use it. So I guess I got what I paid for in that I paid nothing for the app and it gave me NOTHING in return. The app is the main component to this ring. Without a good app this ring is worthless. Now, let's get into the ring itself because before I even discovered how horrible the app was I had to unbox the ring, and in unboxing the ring I was pleasantly surprised by how nice it looked in the Dune colorway - the only good thing I have to say about this ring - and eagerly put it on just to discover it was too big! Did I mention I purchased the ring sizing kit? Sure it only cost a $1 to the competitor's $10 but still... what's the point of offering the sizing kit if the sizes don't actually align?! At that point I hadn't known what was to come with the app itself so I was planning on ordering another ring in the size down. Good thing I didn't because it ultimately wouldn't have mattered with the state of the app. I only make note of this to point out that even with the first impression being an ill fitted ring I was still excited and looking forward to getting the ring set up and running because truth be told I had been looking forward to the delivery of this ring all week! I'm genuinely so bummed that THIS ended up being my experience with it. If you're still reading, the lesson to be had here is choosing the cheaper option is not always the deal you think it is, and in this case it was very much a bad deal. That's not to say the more expensive competitor ring is the better deal because for all I know that ring's app could be just as mediocre but ultimately I don't know and honestly have no intention of finding out anytime soon. All I can say for sure is this ring's ring sizing kit is inaccurate and this ring's app is a whole joke so don't be fooled like I was. 1 obligatory yet deserving star for the dune color and nothing else. Update: I've now worn this ring across two different fingers for about a week's time each and both fingers spurred blisters beneath the ring. It should also be noted that my initial sizing issue hadn't been an issue of the ring being too small but rather too big, so I can't even write off the blistering to it being too small for my fingers because it's not. Additionally, I’ve also found the charge doesn’t last nearly as long as advertised. For example, after a full charge the app told me I had 9 days of battery life remaining. When I checked in on the app 4 days later following a workout I was surprised to find nothing from that session had been logged because the ring was dead… 1 1/2 days dead, which I hadn’t realized as I hadn’t checked in on the app the day prior! Also strange, the step counter is crazy inconsistent and the calorie counter is just broken as it never really changes much. I tested in comparison to my iPhone’s Apple Health data and it’s way off some. It will say I burned 400 calories with less than 200 steps and then if the steps reach 5k the calorie counter only grows by 10 or something. Make it make sense!

The ring’s sensor suite delivers on every promise: heart-rate variability, sleep stages, and daily activity all sync quickly to the companion app, and the data trends have been consistent with my smartwatch. I have worn it day and night for a few days, and it is comfortable enough that I barely notice it—even during workouts or while typing. Battery life hovers around eight days per charge, which feels generous given the continuous monitoring. My only disappointment is the finish. In the product photos the bronze appeared muted, almost like brushed stainless steel; in person it is a highly polished, mirror-like bronze that catches far more light than I expected. It is still attractive, just much flashier, and it clashes a bit with my other jewelry. If a subtle look matters to you, be prepared for a shinier ring than the images suggest. Overall, the tracking performance earns high marks, but the color rendering in the listing could be more accurate.

Ik heb heel erg lang zitten kijken naar een geschikte ring. Ik wilde eigenlijk niet zo'n 'lompe' ring. En gewoon een om mijn ringvinger. Deze is gewoon, fantastisch! Niet te groot, en ongelooflijk wat deze ring allemaal meet. Hij is preciezer dan de metingen met mijn smartwatch. Slaaptracking is heel erg precies, voor de vrouwen onder ons, menstruatie tot op de dag na nauwkeurig...ja toch handig om te weten 🤭 en alles omtrent verdere gezondheid is gewoon super fijn om te kunnen zien. Ik ben fan!
