ULTRAHUMAN Ring AIR - Matte Grey - Size 11 - Smart Ring | No Monthly Subscription | Size First with Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker

Love the appearance, and the data tracking is very accurate. I did have a slight issue where Sleep tracking randomly stopped for 1 month, but the in-app support team replied the next day and immediately offered a free replacement which fixed the issue. Great product, and great support.

The Ultrahuman is a fantastic piece of kit. The app works great, with constant and consistent updates. Very fairly priced vs their competition.

Very bad product, defective piece. It was a present for my bro in law and it was so embarrassing that it did not work. Have asked for a replacement from ultrahuman, but the time scales are very long. Not happy at all 👎🏻🙁 I have been sent a replacement ring and it has the sane issue. I think i will return the product and get a ring from a different company.

If you want to be harassed every few minutes by incessant notifications that add no value with no way to choose which notifications are most meaningful to you, this is a great buy. It'll pester you constantly, interrupting your work day and flow state to tell you things you don't need to know. Your choices in dealing with the blabbermouth app are: disable notifications at the OS level for the app or tolerate it. I chose the former.

I've had the ring for a week now. Pros The ring is fairly slim, which is why I chose this product, and it looks good. The app gives a great deal of information and lots of instruction. Still going through it all as the data builds but very impressed so far. No subscription Cons The size 11 ring in the sizing kit fit perfectly. I wore it for a whole week before I ordered. Ring arrived and it is too big. HR is inaccurate. But this could be related to the point above.

Unlike a watch the ring is very comfortable to wear whilst sleeping..still getting used to health tracking but seems informative and accurate..app is easy to use and nicely laid out ....very happy with my purchase 👍

I've been using this for over a year now ,and the ring has proven reliable and accurate. It's comfortable and light on the finger even when asleep.I have found the data to be useful from both a health and fitness perspective. Having no subscription fees puts it to the top when I considered my purchase,highly recommended and the customer support is first class.

I ordered a size 11 after using the dummy kit, however the ‘11’ I received definitely feels smaller so going to have to return for a 12. The app is pretty good, shame some of the more useful apps are behind a paywall, that’s pretty disappointing considering the strong selling point of ‘no subscription’. The hr was surprisingly good during a spin class, took a few minutes to settle but was on a par with my Garmin, Rhr, Vo2 and Hrv almost the same as Garmin (interestingly they were way out on a Huawei watch I recently tried). All in all I like it and think Ultrahuman have done a fairly good job with new tech, hopefully it will keep getting better as they seem to be proactive with software updates.

The Ultrahuman Ring Air isn’t just a wearable—it’s a wellness statement. From the moment I unboxed it, I knew this wasn’t another gimmicky health tracker. It’s forged from fighter jet-grade titanium, featherlight yet durable, and designed with a minimalist elegance that makes it feel more like a premium accessory than a piece of tech. What truly sets it apart is its silent intelligence. There’s no screen, no buzz, no distractions—just pure data flowing into the Ultrahuman app. It tracks sleep, recovery, movement, heart rate variability, and even stress levels with remarkable precision. The app interprets them, offering actionable insights that feel like they were crafted by a personal health coach. One of the biggest wins? No subscription fees. Unlike other smart rings that lock insights behind paywalls, Ultrahuman gives you full access from day one. That transparency builds trust, and it’s refreshing in a world of hidden costs. Battery life is solid—about five days per charge—and the ring charges quickly. It’s comfortable enough to forget you’re wearing it, though I did swap it out during heavy lifting sessions to avoid scratches. Sizing took a bit of trial and error, but once I found the right fit, it was seamless. In short, the Ultrahuman Ring Air is a quiet powerhouse. It doesn’t shout for attention—it earns it through performance. If you’re serious about understanding your body and optimizing your health, this ring delivers. It’s not just wearable tech—it’s a lifestyle upgrade.

Lamentablemente los valores no estan nada cerca, aunque la batería si funciona los 5 dias !!!

Lasted around 6 months and failed. Got a replacement under warranty. This one after about 6 months have started cracking on the inner side rendering it useless. The software is good the tracking is good , hardware strength is no good. I used it continuously day and night , only exception during hand wash and bath. Never dropped it even once , as days go by the inner material expands slightly and can be felt when placing in charging dock as it does not slide in easily. These issues have to be addressed by UH. Will I go for one more ? May be not after the bad experience and steep cost of owning one , that can't last a year. Mine is still working but may Crack off anytime . Addressed the issue to Customer care and promptly they send me the second replacement , keeping my fingers crossed and hope this one lasts.

Good buy. Rakes some time to get used to.

Sehr gute Funktionen, hat auch einen Monat lang perfekt funktioniert. Jetzt ist aber vermutlich der Akku defekt, kein Problem, lieber jetzt als nach Ablauf der Garantiefrist. Ich tausche den Ring um, freue mich schon wieder darauf.
