## Description

Product description

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: Game Changer for Sleep Apnea & Daily Activity - I’ve been using the RingConn Gen 2 for a while now, and it has become an essential part of my daily routine. As someone managing sleep apnea, the level of detail this ring provides is incredible. It tracks my AHI (Apnea-Hypopnea Index) and blood oxygen levels throughout the night, which gives me peace of mind and real data I can actually use to monitor my health. What I love: • Sleep Tracking: The sleep apnea monitoring is top-notch. It even flagged a significant oxygen drop for me, which really helps in understanding my sleep quality. • Step Counting: It’s surprisingly accurate with steps. I’ve compared it to other trackers, and it holds its own perfectly. • Comfort: It's lightweight and comfortable enough to wear all day and night without irritation. The Trade-off: The only thing to keep in mind is the battery life. While it’s rated for longer, using it as a dedicated sleep apnea and oxygen tracker means the battery drains a bit faster—I usually get about 7 days out of it. Honestly, for the amount of vital data it’s pulling while I sleep, that’s a trade-off I’m more than happy to make. If you’re looking for a discreet, powerful way to track your health and sleep, I can’t recommend this enough!

### ⭐⭐⭐⭐⭐ A Lifesaver!
*by J***E on March 30, 2026*

This is a great smart to track a variety of vitals. I specifically needed a smart ring that would measure my blood oxygen and track sleep apnea events and hypoxia. Not many rings can do that but this one can. Well worth the money, I have it on all the time, and I work as a mailman, so I'm on there in all elements wearing this, in the shower, at work, asleep, still works perfectly. I couldn't be happier and I daresay this product helped save my life. I ended up getting a cpap because it confirmed I had severe sleep apnea. Tracks your steps, heart rate, blood oxygen, kcals burned, sleep quality, stress levels (although the stress level accuracy I don't think is very accurate). I switched from the fitbit to this, comfortable lightweight and has a long battery. BE SURE to FIRST GET THE RingConn sizer. Itll be a box with a bunch of different size plastic rings. Its important because the girth of your finger changes throughout the day and its important to find one that fits well and is comfortable for all day use.
