The best Smart Ring with No subscriptions
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!

I love it so far!
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.

Great Health Tracker!!
I absolutely love this ring! It checks every box for me at a much better price point than competitors. The slimmer band is a huge plus — it’s more comfortable than others I’ve tried and easy to wear 24/7 without even noticing it’s there. The charging case/carrying case is honestly a major win. I much prefer it over a traditional charging stand. With cats in the house, a stand would’ve lasted about five minutes before becoming a toy. Being able to safely tuck it away and only charge it for about 30 minutes every 11–12 days is super convenient. I’ve definitely put it to the test — worn it straight for nearly 2.5 weeks through gym sessions, cooking, cleaning, sleeping, showering, and even wood projects. It’s held up great. I really love the features and the health data it tracks — it’s been insightful and motivating. Overall, I’m extremely happy with this purchase! Also a HUGE plus is the charging case stores additional hours to charge the ring so if I’m out of the house and it ever need a charge it’s as easy as popping it in the case and then in my purse and grabbing it 30 minutes later!!!

Great fitness ring!
I ordered this fitness ring on July 10th, 2025, so I've had it for about 5 months now. What is making me finally write a review is that I accidentally just put this ring through the wash and you couldn't even tell. No damage at all from being in all that water and washed around with soap. I honestly really enjoy this ring. Pros: -Great battery life -Charging case also has great battery life -Free app that is user friendly and a bit customizable -Ability to track steps, sleep, exercise, sleep apnea, periods, heart rate, oxygen saturation, body temp, stress, and add notes. -With accuracy in tracking for steps, sleep, vital signs, exercise, and stress. -Useful information in the period section, about which part of the cycle you are in and what to expect. -Multiple types of exercise you can track from HIIT, sports, walking, etc. -Sleep is quite accurate I think, and gives you how long in each stage, heart rate variability, temperature, respiratory rate, naps, time in bed vs time asleep, and a subjective tracker for you to make how you feel. -You can track so many things with your period, I love the detail. See attached photos. -Sleek and easy to wear, not heavy at all. -Waterproof!! I wear this ring while washing my hands, washing dishes, accidentally left it in my pocket and put it through the laundry. No visible damage, and no issues with use. Cons: -Sizing is iffy. I ordered a size 11 for comfort but I think sleep apnea tracking would be better if I had a size 10 because it's closer to the skin although too tight for my comfort. -Touted for sleep apnea monitoring but doesn't seem to be accurate when compared to my home sleep test and cpap machine. Unfortunate, but hopefully they hone this tracking aspect in the future. -I haven't been good with remembering to track my periods in the app on top of my written planner, so I can't tell how accurate that is yet. -Poor gps tracking for walks and runs. I will start and end the walk timer for the duration of my walk which could be anywhere from 1 to 3 mi but will only chart that I did 0.05 miles. Luckily you are able to edit the mileage. Overall I love this ring and it's features, which are worth the midrange price tag.

Absolutely love this ring
Nothing bad to say about this ring, super light weight, durable. The app is very easy to use. Seems to do very well at taking everything. The sizing kit was spot on and well worth the extra buck to verify size fit and comfort. Battery life is excellent. Only thing I would like with this ring is the ability to change the quick pick options for exercise on the main screen if the app, the 7 preset ones are the only ones and can't be changed based on personal preference. Overall ... EXCELLENT and will definitely upgrade to the gen 3 when available.

Richtig getragen liefert der RingConn Gen 2 eine beeindruckende Genauigkeit in der Erfassung von Bewegung und Schlaf. Die Apnoe-Überwachung funktioniert mit plausibel erscheinenden Analysen. Ein Beleg der Werte ist letzten Endes nur durch medizinischen Abgleich möglich. Um über diesen Schritt in ein Schlaflabor und weitere Maßnahmen zu entscheiden, liefert er ein sehr gutes Tracking. Über Varianten der verschiedenen Sportarten kann ich nichts sagen, für mich ist der Alltag entscheidend. Dafür klare Empfehlung, in Roségold ein schöner Hingucker für Frauen. Das Tragen ist angenehm, die wenigen Minuten für den Datenabgleich sollten für jeden möglich sein. Der Akku ist topp.

Just got my Ringconn Gen 2 - setup was a breeze and am excited to start collecting data. Have to say - after reading several comments that the ring fits big, I was a bit worried about sizing but the size 8 I ordered was 100% correct according to the initial ring-sizer I chose from the kit. On top of that, this ring is, quite simply, beautiful. It’s very lightweight and almost feels undetectable on my finger. The gold is not brassy and it looks like an expensive piece of jewelry. 11/10 for fit & style! I got this specifically for the sleep apnea tracking - hoping it performs as well as it looks! Will be back with an update.

Se tarda mucho en llegar y una vez que llega, te lo pruebas y dices “pues lo regreso, ahí dice que se puede” y si, se puede, pero lo que no sabes es que el envío corre por tu cuenta y amenos que quieras mandarlo por correos de México y darle la bendición, mejor olvídalo, que el envío sale más caro que el mismo producto. Ya tire el mío a la basura
