    I ordered this smart health ring because I’ve been looking for a way to track health stats without wearing a bulky watch all the time. The sizing kit made it easy to figure out the best fit before committing, which I really appreciated. It’s comfortable, lightweight, and once I had the right size, it didn’t feel intrusive like some other wearables I’ve tried.

    What makes it stand out is the range of health features packed into such a small device—heart rate, blood oxygen, HRV, sleep tracking, and steps, all without a subscription fee. I’ve tested it against my smartwatch, and the readings have been surprisingly accurate. The sleep tracker has already shown me patterns I wasn’t paying attention to, which helps me make changes to my evening routine.

    For someone who wants to keep an eye on health metrics while juggling work, family, and daily responsibilities, this smart ring has been a practical and subtle solution. It’s also waterproof, so I don’t worry about taking it off for chores or when playing with my boys outdoors. This has been a five-star purchase, and I will update my review should any issues occur.

    Glad I got this set. It provided me the right size I needed for my Smart Ring, and prevented me from getting the wrong size. This saves the guess work, and worth the few bucks to find out the size I really needed.

    After getting the Smart Ring, and being blocked from doing a review on it, I’ve added it here, so beware of these APPs (see pics).
    The Apps want full access to your phone, your text messages, photos, and contacts, and…access to DELETE your contacts. How’s that for something you want to have on your phone? Even if you opt out, whose to say they still don’t have access? I’m not sure what the charging block is for either, as I used it to charge the ring, and it showed fully charged, then used the magnetic cord to charge the ring directly, and it charged for another 2 hours…so what’s the block for? As for accuracy of the ring, it’s understood it’s for reference only, so don’t take it as official tracking. I use mine basically for sleep, and it’s not bad, but it’s way off for blood pressure. Steps are close, but not great. The SP02 reading is fairly accurate as well. I tested this against my other meters for verification. The App is from China, so you are giving them access. Read the Privacy Policy.

    I picked up this fitness tracker ring because I wanted a simple way to monitor my heart rate, sleep, and steps without signing up for another subscription. It’s definitely not packed with advanced features, but for what it does, it works surprisingly well. Heart rate and sleep tracking have been accurate so far, and it syncs easily with my Android phone.

    It’s lightweight and comfortable enough to wear all day and night. I like that it’s waterproof, so I don’t have to take it off when washing hands or during a quick shower. The app is basic but clear, and it gives me what I need at a glance. It’s not trying to be a full-on smartwatch, which I appreciate.

    The best part is the price. Compared to other smart rings, this one is a lot more affordable and doesn’t lock you into a monthly fee. If you just want a no-fuss way to track your health and daily activity, this ring is a solid choice. Four stars because it’s basic, but it works.

    This a replacement ring for my granddaughter as she wanted a different size and color. Myself and four of my family members have these health rings. It delivers continuous, high fidelity health tracking without the distractions of a screen or bulky wrist device. It is my invisible health coach. It tracks steps, miles calories burned, heart rate, oxygen level and sleep pattern. The ring is waterproof so it can be worn in the shower or even swimming. It consistently stays charged for 6 to 7 days. Recharging is quick. The QRing app is simple to download with easy to follow instructions for pairing it with your phone. It works for both android and Iphones. My family members love their rings and we enjoy competing with each other to see who has the best activity score at the end of the day. I highly recommend this Qring

    I’ve been testing this Smart Ring for a few days and I’m honestly impressed! The design is sleek and minimal it looks like a stylish piece of jewelry, not a gadget. It’s lightweight, super comfortable, and fits perfectly on the finger (I wear size 8). The sensors track heart rate, sleep, and activity quite accurately, and the connection with the app was smooth and quick. I love that it charges easily in its compact case and holds battery for several days. It’s a great option for anyone who wants to monitor health without wearing a bulky smartwatch. Definitely worth trying!
