  • Good 😊
Color: Rose Gold Size: 7
⭐⭐⭐⭐⭐ Absolutely love this smart ring! The BIEMHA Smart Ring has exceeded all my expectations. It’s lightweight, comfortable, and the rose-gold finish looks incredibly stylish. The health tracking features are surprisingly accurate — especially sleep, heart rate, and activity monitoring. I really appreciate that it works smoothly with both iOS and Android, and the app is simple to use and very clear. One of the best parts is that it doesn’t require a subscription, which saves a lot of money compared to other brands. The battery life is excellent too — I easily get around 5 days on a single charge. Overall, this ring is perfect for anyone who wants advanced health tracking without wearing a bulky watch. Highly recommended! ... show more

  • Elegant, Accurate, and So Convenient!
Color: Rose Gold Size: 16
I absolutely love this Smart Ring! The rose gold design is stunning—it looks like a piece of jewelry but works like a high-end fitness tracker. It’s super comfortable to wear all day and even while sleeping. The sleep monitoring is spot-on, giving me great insights into my rest patterns. I also appreciate the stress and heart rate tracking, which help me stay mindful throughout the day. The 10-day battery life is incredible—no need to charge constantly! Best of all, there’s no app subscription, just seamless syncing with my phone. It also very durable, I do a lot of crafting, gardening, that kind of thing and I am very hard on my hands and I have been wearing the ring for a while now and not a scratch on it! Worth every penny! It’s the perfect blend of style, simplicity, and smart tech. Definitely a 5-star product! ... show more

  • Not user intuitive and limited resources
Color: Rose Gold Size: 9
1. Took me awhile to get the device to be seen in the app. 2. I didn’t read until the next morning, hen there was no sleep data, that it wasn’t ‘connected’ even though it was shown in the list. There were no instructions to do this step 3. The user manual is very short and didn’t newer lol my questions, and I’ve worn another brand before. 4. There is a help section in the app, BUT all the information is specific to wearing a wrist device not a ring. UPDATE 1. The ring is thicker than others and uncomfortable to wear 2. Doesn’t seem to function correctly/at all-tired of trying to figure it out. ... show more

  • Beautiful Ring, Hit and Miss Tracking
Color: Rose Gold Size: 16
I’ve been wearing this ring daily (except for showering) since October, and it is very comfortable and fits perfectly. It’s low-profile and doesn’t look like a health tracker, which I really like. The app is easy to use and syncs perfectly with iOS, so connecting the ring to your phone is a breeze. The charging case works well, and the battery lasts about 5 days before needing a full charge. Tracking results are mixed. Blood pressure readings are impressively accurate, often almost identical to what I get at the doctor’s office. However, other metrics, particularly steps, are inconsistent and usually too low. Because of this, I wouldn’t rely on it as my only health tracking device—it’s more of a supplement than a replacement. In terms of durability, the ring hasn’t turned my finger green or tarnished, even with frequent hand washing and sanitizer, so it’s at least somewhat waterproof. It has picked up some scratches from daily wear, but no dents, which is impressive considering I’m not careful with my hands. Overall, it’s a well-made, comfortable device with some strong features. The inconsistent tracking keeps me from giving it a higher rating, but it remains a nice low-profile health tracker with good comfort and battery life. ... show more

  • I like!!
Color: Rose Gold Size: 16
I didn’t expect much at first, but this ring really surprised me. It looks great, feels super comfortable, and tracks everything I need — heart rate, sleep, and steps — without having to wear a watch all the time. The app is easy to use and connects fast, and the battery lasts way longer than I thought it would. I charge it maybe once a week. Honestly, it’s stylish, works perfectly, and makes it easy to keep an eye on my health. Totally worth it! ... show more
