Order 1 size up!
I’m usually a ring size 7. But it was too small had to return - I’d recommend getting 1 size bigger, the ring is comfortable, light and looks good on. The app is very good. It’s not gold - more of a rose gold/bronze colour

works great
I'm positively surprised by the RingConn ring and can truly recommend it. It's very comfortable to wear and does a great job tracking vital data. While the current selection of sports modes is still quite limited — so it doesn’t fully replace a sports watch — it’s excellent for overall health monitoring. Looking forward to future updates with more activity options!

NOT GOLD COLOR
I assumed it would be muted gold but it is totally different color, it is more brown than gold, it works fine for now as I just got it but I was disappointed with the color.

Der RingConn Gen 2 Air hat sich bei mir schnell zu einem ständigen Begleiter entwickelt – und das nicht nur wegen der technischen Features. Schon beim ersten Tragen merkte ich, wie unauffällig und leicht er ist. Ich vergaß teilweise, dass ich überhaupt einen Ring trage, was ein echtes Plus ist, wenn man sonst täglich mehrere Uhren oder Fitness-Tracker am Arm hat. Die Akkulaufzeit von bis zu 10 Tagen hat mir im Alltag sehr geholfen. Ich erinnere mich, dass ich einmal über ein langes Wochenende verreist war und den Ring vergessen hatte mitzunehmen, erst als ich zuhause war, fiel mir auf, wie sehr ich die Daten für meine Routine tatsächlich vermisst habe – ein klarer Beweis dafür, wie sehr man sich an dieses kleine Gadget gewöhnt. Auch die Stressmessungen haben mich oft überrascht. Ich war einmal im Homeoffice kurz vor einem Meeting ziemlich angespannt. Als ich auf den Ring sah, zeigte er höchste Stresswerte an. Das brachte mich tatsächlich dazu, 5 Minuten bewusst zu atmen, bevor ich ins Meeting ging – und die Technik hatte mir quasi einen Mini-Reminder für Selbstfürsorge gegeben. Die Integration in Apple Health ist ebenfalls praktisch und hat mir schon oft den Überblick gerettet. Ich erinnere mich, dass ich einmal meine Schlafstatistiken angeschaut habe und feststellen musste, dass ich über mehrere Tage viel zu spät ins Bett gegangen war. Dank des RingConn konnte ich meinen Rhythmus bewusst wieder anpassen, und ich fühlte mich sofort wacher am Morgen. Optisch ist der Ring auch ein kleines Highlight. Ich habe schon einige Freunde überrascht, als sie ihn an meinem Finger sahen und dachten, es sei ein schlichter Schmuckring. Dass er gleichzeitig so viele smarte Funktionen hat, war für sie ein echter Aha-Moment. Auch mein Partner findet ihn hübsch genug, dass er ihn als „Alltagsaccessoire“ akzeptiert – was bei smarten Gadgets ja nicht immer selbstverständlich ist. Preislich habe ich ihn im Deal für 189 € bekommen, aber selbst der Originalpreis von 239 € ist im Vergleich zu Konkurrenzprodukten noch fair, insbesondere wenn man die Akkulaufzeit, Präzision der Daten und die Abo-freie Nutzung betrachtet. Fazit: Der RingConn Gen 2 Air ist nicht nur ein technisch starkes Wearable, sondern auch ein treuer Begleiter im Alltag, der auf subtile Weise hilft, den Überblick über Schlaf, Stress und Herzfrequenz zu behalten. Mit seinem eleganten Design, der langen Akkulaufzeit und der einfachen Apple Health-Integration ist er ein Gerät, das man schnell liebt, vergisst und gleichzeitig schätzt – eine klare Empfehlung für alle, die smarte Technik menschlich und praktisch erleben wollen.

There are enough sizes to find your perfect size. I have a size 10 on my right pointer finger. UPDATE: I have officially bought it and it came in yesterday! My first impression on it was that it feels like cheap plastic, but when I went and read the materials it’s made out of it made sense in order to keep it lightweight. As I’ve only had it for 24 hrs I can’t give a good review if it’s worth it or not but I will update again later. I order the size 10 as the sizing kit let decide which size would work best, it fits the same if not a little bit bigger than the sizing ring but nothing that I would need to size down. The silver looks great with the rest of my silver/white gold jewelry. The set up was easy and everything within the app started working immediately, I wore it to bed to get my sleep tracking going and it tracked it to the T! The cycle tracker is off but it only asked about my last one and I just had to guess so as I use it more and am able to put accurate data in I’ll be able to know how well it is. I’ll update in a few months.

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.

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.
