I’ve now had the Ultrahuman ring for a few weeks and I wish I’ve had this my whole life! The first thing I noticed is how lightweight the ring is, you really don’t even notice you’re wearing it. It matches the rest of my gold jewelry and really looks like a simple gold ring. It's very durable and is yet to show any sort of wear and tear. The layout of the app is easy to follow and organized. It is practically identical to its competitors but much cheaper and offers additional features. My favorite thing about the ring is that you can initiate the tracking of workouts, and it will appear on your phone. This is super helpful when I want to compare the workouts I do to my total activity for the day. I’ve also enjoyed tracking my sleep and circadian rhythm. These two features, along with the ability to track your caffeine window, have all helped me build a routine and feel more energized as a result. The battery life is impressive, I can go almost a week without having to charge it. And when I do need to charge it, it reaches 100% battery quickly. Overall, I will be recommending this ring to many of my friends with different lifestyles. This ring is the best way to track your health and wellness and avoids looking like a distinct piece of wearable technology.

I’ve had the UltraHuman ring for about 3 weeks so far and it’s quite interesting. It has a wide range of information that you wouldn’t know or find out by not having one. From body temperature, sleep tracking, steps in a day and much more. It also has a built in workout system so you don’t have to find them on the internet or anything. The down side is the battery heath which only last about 4 days and less if you keep looking at the app for information. Over all good and has a sleek look. I have the Aster Black color
