[This review was collected as part of a promotion.] Been using the Ultrahuman Ring Air for about 4 months. Overall experience is very good, I really enjoy all the detailed info the device collects. Far more detailed, accurate and helpful than any other device like smartwatches. Battery could be better but it’s not terrible. Some features in the app require an app to be running in the background. Smart alarm in my case sometimes isn’t turned on due to app not running in the background. And the majority of time it only triggers with a fallback timing.

[This review was collected as part of a promotion.] I have been a customer since Ring R1 for the ease of use for health tracking (especially sleep), and when they launched the Ring Air it just got even better with all the useful functionalities in an even smaller form factor. Just crazy how tech has evolved.

[This review was collected as part of a promotion.] Best investment in my health in a long time. It's been incredible to have instant access to so much useful data in such a simple and easy to understand way. I only need to glance and I have so much information throughout the day. I originally got this purely for the sleep tracking but I have quickly found every aspect of the ring useful - the insights I'm getting are so worth it. It's also such a plus not having to pay a monthly subscription for the app.

[This review was collected as part of a promotion.] I bought this ring in November and overall it’s fine, but I don’t think it’s super accurate. If I charge it overnight, it will still say that I slept and gave me a sleep score but I wasn’t wearing it. This has happened multiple times. It’s nice to wear and not bulky on uncomfy. Also I think the goals/metrics are mostly for walking, I don’t think it tracks other activity well. Also my charge will only last a day if I try and log any activity.

[This review was collected as part of a promotion.] I got my ring around 9ish months ago. It was my way to start tracking my sleep health and an attempt to make better life choices. Also to compare my activity trackers. Overall I’ve seen an improvement in my sleep patterns and can make adjustments when needed.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a while now and have truly enjoyed the product. The overall experience has made me feel that health should be approached through the Ultrahuman Ring and their app. I like the caffeine window.

[This review was collected as part of a promotion.] Up until a week ago it was working fine, registering my values efficiently. After the latest update however, the battery doesn’t last a whole day anymore. When it was new I didn’t need to recharge it for approximately 3 days. I like wake up function (found a favourite tune) and I use it almost daily. I don’t have a second devise to compare the functions to so can’t really say much about its accuracy. However, I chose this ring above Oura simply because it doesn’t require a subscription to see the more complex values from recording your sleep. Another reason for choosing this over Oura was the aFib detection and cardiofunction, but I got quite disappointed from learning that these two functions require a subscription. On the plus side I like the layout and I find the info about all things it contains to be interesting.

Feature improvements: - heart rate button (real time sometimes I want to check) - Same day activity detection instead of the next day - Better small walk detection - the app tells me to move but then labels my stress as high - Deep sleep and main hr drops seems to be a bit spotty which makes for a pretty extreme move in my restfulness scores That aside I really enjoy the product and it’s worked well for me!

[This review was collected as part of a promotion.] I’ve been using it now for 2 months and am really happy overall with my experience. As a runner, I find all of the cardio age and vo2 max statistics really helpful and it’s been great to see them changing the longer I use the ring. The battery is good, I charge it whilst I’m at my desk every few days or so and it’s relatively fast to charge to full battery. My only reason for not giving it 5 stars is the period tracking. I was under the impression that as it measures your body temperature it would predict cycle outcomes based on this, not just 28 days. As someone with an irregular period, if it is late, the app just says that my period is in an unknown phase. It seems to basically be their own version of an app such as flo. I don’t find it to be any more accurate, despite the body temperature measuring.

[This review was collected as part of a promotion.] This has been soooo helpful especially with sleep and now I know why I am so tired! It has also helped me with my activity level and has made me increase my steps - daily. The only thing that I have an issue with is sometimes when I have an activity running, for example I’m out running. It will randomly just close out and I have to start over again when I’m already midway through my workout.
