Review: Love it way more than my Whoop - I switched from a Whoop, in part because it still wasn't totally comfortable sleeping with it on, and because the annual subscription was so expensive... I was originally waiting for the Ringconn Gen 3 to come out, but then I lost my Whoop charger on a plane, so I ended up grabbing the Gen 2... So happy I did! I may upgrade later, but honestly, the Ringconn Gen 2 is ticking all my boxes so far. It's super comfortable to wear, I normally wear it on my middle finger of my right hand (I'm left handed) but it also fits perfectly on my index finger, so I can switch it over if I get that soft soggy white ring rash, and just wear it for a few days on the other finger. The battery life is great, I just got into a routine of charging it on a Sunday afternoon while I'm chilling, and it only takes an hour or so to fully charge. It still has a few days charge left if I'm busy and don't get to do it on a Sunday, but I like the routine. I wear an Apple Watch Ultra for most of my fitness tracking, but the Rigconn actually picks up those short duration activities that the Apple Watch doesn't... spend 20-30 mins mixing and laying concrete or doing yard work, and Ringconn picks it up, while the Apple Watch typically won't. I also like that it's measuring the morning light exposure during the first hour after wake up... this one surprised me, but it's actually using it's sensors to detect the intensity and color of the light after you wake up... getting natural sunlight after you wake up helps depress melatonin production and improves wakefulness... it gives you a running measure of your wake up light exposure and differentiates between natural and artificial light! The app seems to be constantly improving. This was the one perceived weakness with Ringconn, but I can honestly say that I have seen clear signs that they are actively developing the app in the right direction, and also that they have been extremely responsive to user feedback... the responses to questions and feedback have been way more than canned or AI generated replies, they truly seem to welcome and respond to feedback. I love the no subscription model, and that they openly share data with Apple Health so it drives other apps as well if I want more specialized focus, but honestly, I think they are quietly building out their app in all the right areas, and I'm loving the platform. I have friends with other devices, and the Ringconn seems generally more compact and wearable than most I've seen. I'm so glad I switched, and I won't feel bad if I invest later in the Gen 3, but I don't feel like I'm missing anything now, so it will be because it offers something else I want, not because it fixes a gap in the current iteration!
Review: Company is engaged - Came upon Ring Conn in my research for a smart ring. Looked at the competitors extensively and found Ring Conn met and or exceeded what I was looking for. Essentially it checked all of the boxes. Ordered the Ring sizing kit that is available and pulled the trigger. I was pleases/satisfied with the rings function and it's interface with the app. (No subscriptions btw). About 8 months in, the battery began having issues with operating duration. I skeptically reached out to the company. What I was expecting and what transpired caught me by surprise. Their reply was speedy, concerned and action oriented. They asked a few questions and in a matter of days, a replacement Ring arrived complete with instructions to move data over and included return supplies. The replacement functions as intended and fit and finish is as new. Ring Conn's response and corrective action was engaged and thorough. Impressive and exceeded my expectations. My message to them is included as the entire process was top level. "I have received everything as expected and I believe i successfully disconnected the old ring from my info. I feel the replacement process went very well and exceeded my expectations. I would be happy to provide a review of the process or you could use this reply. There were no bumps or hiccups to complicate the process. I found everyone to be helpful and the goal seemed to be a positive problem free process. Which was successful. I appreciate your attention to the matter as if I was the only one that mattered. Thank you for your assistance and the goal was obvious. To make things right. You did!" I would not hesitate to conduct another transaction with them. All positive!

### ⭐⭐⭐⭐⭐ my yellow gold Gen 2 ringconn is pretty, accurate, & anti-scratch!
*by H***A on July 11, 2026*

Everything from its pretty aesthetics to its battery life to its functionality & accuracy is PHENOMENAL! It’s so slim & sleek (noticeably less bulky compared to the Oura Ring!) And it blends in with my other yellow gold jewelry! In over 6 mths the yellow gold color hasn’t tarnished or scratched off (like customer reviews say the oura ring does!) It truly IS waterproof! I never take it off when washing my hands or washing dishes & it still works great! I’m so impressed with how accurately it detects my sleep patterns, & it knows if I fell back asleep or took a nap! It also has everything I need for tracking my cycle (you can input notes & symptoms etc). I really purchased this ring because I wanted the BBT feature to track my ovulation, but it only reads your SKIN temp so it’s not as accurate as I’d hoped… Helpful “Find My” Feature: I misplaced my ring in the house the other day so I used the app to find it by sounding a beeping alert & lighting up/glowing blue! And the map on the app accurately showed exactly where in the house my ring was! It is so precise! The battery life is VERY LONG (8+ days!), and the charging time is SUPER QUICK! (like under 45 min!) And you don’t need to pay extra $ for the APP (unlike other competitors!) which is a big plus! Overall I am SO impressed with this fitness ring and I highly recommend! UPDATE: My mother in law wanted the silver GEN 2 ‘AIR’ for her birthday & she loves it so far! (see the pic of it on her pointer finger. It looks great on the same hand as her white gold wedding band!)
