Wonderful and Great Value
Wonderful and great value. Bought this as a Christmas present for my wife. I did some research on the Oura ring and others before choosing this. This stood out as being cheaper and with an app that is free to use (unlike the Oura) The ring arrived beautifully packaged, like an Apple product. It works well, the App is great and the data produced is surprisingly deep and broad. Strongly recommended.

A great ring, just what I wanted.
I have been using my Ringconn for a few weeks now and feel I can add objectivity. I chose Ringconn due to its lack of subscription and because I have watched and read many positive reviews, and I am delighted with my purchase. First, the great bits: the battery life really is 11 days, and it recharges quickly. I don't take the ring off unless I'm charging it. The charging case is convenient and protects the ring in the process. Sleep recording is more accurate than my watch. My watch generally overrecords my sleep, especially if I read before falling asleep; my ring seems more accurate. When I wake up feeling more refreshed, my sleep score reflects this. As a Sleep Apnea sufferer, I am delighted that I can keep an independent eye on my treatment. When staying away recently, I had to sleep without my CPAP machine for one night, and the ring data reflected this appropriately. The step counter seems to be accurate. Of course, I don't count my steps, but the step counter aligns well with my daily activities. I have also noted that the stress monitoring aligns with my daily ups and downs. I suffered a bout of food poisoning during the second week of wearing the ring and noted several changes to the data to reflect the illness. The software also asked me to explain the abnormality in the data. Overall, I am extremely impressed with the accuracy of the data. I only have one negative: that there isn't a size to fit my index finger. Maybe I have extremely big fingers, although I don't believe that to be the case. I have had to put the ring on my middle finger, which interferes with my wedding ring. I'm used to this now and haven't noticed any damage to the Ringconn or my wedding ring, but it isn't ideal. I thoroughly recommend the Ringconn, I just wish they made a larger size.

Stopped working after a month and rusts!
As an update, over the last month the unit has been really good at collecting date, however over the last week I have had to reset the ring 3 times losing all the data after the app failed to find the device and continually reporting it is sat in the charging base. On top of this, despite assurances you can shower with the unit on (I remove it for any water activity), the contacts on both the ring and charging base are rusting, which has now caused rust marks on my finger. Returning this unit for replacement. I have used AppleWatch before and found it really useful, however the battery life is poor and I prefer a standard watch. I had read about RingConn with interest and decided to try the Gen2. The product is very easy to configure with the app and also exporting the date straight into Apple Fitness and Health. The data that the ring provides is very good and very useful, so all told a pleasant and useful purchase with a battery life around 11 days between charges. The downsides then: - RingConn doesn’t conform to standard ring sizes and you need to try templates to assess the correct size. It would make way more sense to conform to a standard as all rings do. - the ring is quite bulky on your finger, which is understandable given the tech packed into it - I was interested in the Sleep Apnea monitoring after reading the details so decided on the standard instead of the Air (which doesn’t support it). However what is not widely advertised is the disclaimer when you look to enable the option, which wasn’t mentioned anywhere else. Based on the below information I have declined this option: “By tapping "I have read and agree," you signify your consent to activate the "Sleep Apnea Monitoring" feature and agree to provide us with the following data: height, weight, age, BMI, sex, [neck circumference], medical history, OSA symptoms, sleep quality etc. For the purpose of generating an OSAHS assessment report” In summary a great little gadget, fairly accurate, a little bulky for everyday use and not enough detail regarding a key feature which would sway you between the Air and standard version of the product (the air doesn’t support sleep apnea monitoring and is cheaper too).

great tech but a bit of a novelty.
This is a purchase that is quite individual. It is tempting to have a ring with a number of health benefits but i have realised that most of these are duplicated in my smart watch. The two small nodes on the inside bottom of the ring are (for me) very irritating. I am told it looks nice as a ring but it does feel very plastic like - but in fairness this is the coating and they have tried to keep the weight down. Unfortunately, the small weight adds to its 'cheap jeweellery' feel. I wear it periodically but think the technology would need to develop considerably before i made a further investment. Also, from a blind perspective, the companion app is poorly designed for accessibility.

An excellent alternative to more expensive smart rings
An excellent alternative to more expensive smart rings. A comfortable fit - comfy enough to be worn at all times, including nighttime for sleep monitoring. No app subscription required was a real draw for purchasing. Excellent interface. Quality of the ring itself seems good - no scratches yet. Only downside is that it isn't compatible with Vitality - however would feel unfair to mark them down for this!

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

rédigé en janvier 2026 je vient de retirer une étoile, car après Trois mois d'utilisation, nous sommes passé de 11 jours d'autonomie à deux jours à peine . dommage pour un objet à se prix. redigé en novembre 2025 Bel objet, très beau conditionnement. Par contre un peut tôt pour voir se que cette bague vaut, à voir avec le temps. Juste une petite suggestion, un objet de se prix, plus de 300€, mériterait une garantie au moins deux années. Par contre Livreur, Livraison "délai", et Colis impeccable, Cinq étoiles.
