Great for sleep tracking!

[This review was collected as part of a promotion.] I’ve had the Ultrahuman ring for about a month though and I’m liking it overall. It has been great for tracking my sleep and I haven’t had any battery issues. The app has a lot of data which is great, but my one complaint is that it is a little bit overwhelming and hard to navigate.
I would recommend this to a friend!

[This review was collected as part of a promotion.] Really great ring. Bought a few months ago an HD so glad I did. Worth the price and tells me so much about my health I would never have known.

Great ring even after months of use

[This review was collected as part of a promotion.] After having the ring for a couple months, I've enjoyed seeing the information presented for my health. The data is presented in a clear manner and gives some assistance on improvement when necessary.
My only negative is the battery. Initially, the battery was lasting a out 5 days between charges. Recently, it has been an every other day requirement. This isn't a major problem and become just another routine activity to plan in my day/evening.

[This review was collected as part of a promotion.] Bought the ring a few months ago and never regretted it , as my sleeping time is all over, with the parameters given by the ring, I took effort to nap when I have a chance and it makes me more productive in my work.

Poor Battery Life
on July 30, 2025
Posted by: riah
I bought my ring secondhand but brand new. The person I bought it from told me that they sent their original ring back because the battery life significantly dropped after just over a month of use. Ultrahuman sent her a brand new ring which I then bought from her - and I've had the same experience. The battery used to last several days and now it maybe lasts a day and a half. I've only had it for a few months.
Battery life aside, I do enjoy exploring the information provided, particularly my sleep scores, cycle, and movement throughout the day.

Great features

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and the difference in sleep quality and recovery is night and day. The real-time biomarker insights (especially HRV and skin temperature) gave me more control over my routine and helped me make smarter lifestyle choices. It’s not just a tracker - it’s a personal performance optimizer. Looking forward to more firmware upgrades and continued improvements. Great product, strong ecosystem.
