The smart ring can monitor with a lot of sensors and you can review your health information, sleep and movements in the app. The smart ring looks really good on the finger as well. The ring has sensors that can determine your temperature, heart rate, blood oxygen level and blood pressure. It also has sensors for your movement and so can track other aspects like sleep patterns, steps. It is amazing that everything is packed in such a small package and can keep track of those things. You will need the app to see what the readings are and you can view them in your phone. The smart ring has a very cool shiny/matte checkerboard design and it looks really good in the ring. The stainless steel silver color looks good to me and on the finger looks good. For best results, you're supposed to put the ring in the index finger. For me, it didn't fit and only fit in the ring finger. You have to make sure you get the right sized ring and there are the measurements given. I think the best way is to be able to try them on since measuring the fingers and actually the ring fitting are slightly different. The app is essential to using this and it is OK. It shows the health data and that was all I was interested in. It has other options like taking photos but it asks for lots of app permissions and I just only used the health part of the app. The app can be used without creating an account and so the data would only stay with the phone. Since the app is proprietary and it is not explained very well, I didn't know what all the data in the app is and how it works. I want to be able to monitor my health stats at given intervals throughout the day but I couldn't figure out how to get it to collect the data automatically. I can manually collect the data but it takes a minute or two and you have to do it for the 3-4 different types of sensors. It does track sleep, steps and the graphs all look good. The app could be much more polished and some documentation or details would be clear things up. Overall, this is a really cool device and you get very good health information from it. ... show more

    • Easy to wear and recharge. Hardly notice that I'm wearing it.
Color: Black Size: 10#
This tracker is lightweight and performs well. I have tried other ring trackers, but they were often inaccurate in tracking my activities and uncomfortable to wear. In contrast, this tracker is very comfortable and accurately monitors my daily activities. It excels in tracking sleep duration and understanding sleep patterns. Not only can it tell me how long I slept, but it also assesses the quality of my sleep, including the duration of deep and light sleep, eye movement during sleep, and the amount of time I was awake at night between sleep cycles. This helped me fix my sleep issues. It is so comfortable and lightweight that I forget I'm wearing it! ... show more
