I have been using this and comparing with readings from my apple watch. They don't always agree and I can't be certain which is more accurate. I have found that the Ultra Age and the Cardio Age fluctuate quite a bit and are never really in agreement with each other. I do like using the ring to track heart rate during workouts. But, other than that, I haven't been able to use it for much else.

[This review was collected as part of a promotion.] The product performs very well with regards both the tracking of the health data and also the battery lasts around 4 days with full scale continuous monitoring. Easiest how to take care of the battery is to charge during the dinner or when going to shower. The shiny version

[This review was collected as part of a promotion.] Overall, really happy with the superhuman ring. I like all of the things that tracks. If I was being critical, I think that the walking step count can be inaccurate at times especially when driving in the car with bumps it will still record steps so by the end of a very long drive you can have over 10,000 steps recorded Other than that’s great

[This review was collected as part of a promotion.] I have had my ring for 3 months so I feel like I’ve had plenty of time to really utilize its features. I love the sleep data and feedback. I have actually been able to make positive changes to improve my sleep behaviors. I’m also very motivated by my step tracking, and heart health results to move more! Overall, I’m very happy with this investment in my health.

[This review was collected as part of a promotion.] Overall I’m happy with this ring, I am coming from being an Apple Watch wearer and I particularly like being able to feel a bit more disconnected from my phone and have a more ascetically pleasing wearable. I think sleep tracking is extremely good (much better than my Apple Watch that only tracks during my preset sleep window), the nap tracking is a huge bonus. Some tracking metrics (like step count) don’t always seem to be accurate, but they are consistent which is more important to me when tracking trends. It is unclear to me how ultra human integrates with apple health data, but I’ve noticed vastly different data written to certain data fields that are most certainly not accurate. Overall this ring is doing what I wanted it to do and providing decent insight into overall health trends.

[This review was collected as part of a promotion.] I bought this ring for sleep tracking and it does this really well, much better than Apple Watch. so I don't need to wear the watch at night any more! it is starting to give me actionable comments after eg a bad nights sleep, but it is early days to know how this will impact my sleep habits etc. only 4 stars as after a number of weeks it disconnected from my phone and it took a while to sort out what was wrong. I contacted support and I had to do a battery re-set which involved letting battery completely die, which took about 4 days. I then re-charged it for a few hours and it connected back too my phone easily. It will now take a few days to see if I am back on track with data again.

[This review was collected as part of a promotion.] I love the data the ring provides! It has been really interesting seeing what affects my sleep and hoe I can make improvements to help shape how I feel throughout the day. My only negative is how long it takes to charge. I want to wear it at all times to get the data. It would be nice if it could be fully charged in 30 mins so I don’t have to have it off for so long. Overall an amazing product!

[This review was collected as part of a promotion.] This ring has been great, I’ve really enjoyed the sleep tracking and it tends to pick up activity quite well even when I don’t go in and log a workout myself. I moved from an Apple Watch and much prefer the Ultrahuman ring

[This review was collected as part of a promotion.] Have been using the ring for more than a month now, and what blows me away the most is the accuracy of the insights. Sleep tracking is the feature I like and use the most, and the ring being very comfortable to wear to bed is what helps. There is no manual input needed post initial setup, just wear it and consume the insights. This is the best tech purchase I’d made in the last couple of years.

[This review was collected as part of a promotion.] I’ve been using the ring for a couple of months and I’m thankful that it has made me conscious of my overall health. Now, I’ve become conscious of my sleep patterns and also the times I get stressed and their triggers.
