ULTRAHUMAN Ring AIR Smart Ring -Track Sleep, HRV & Stress, No subscription

Over the years I’ve tried Withings, Fitbit, the Google Pixel Watch, and various cheaper off-brand “smart” watches. While some of them do impressive things, I’ve consistently been disappointed — mainly due to poor battery life, awkward small screens for basic tasks, and constant notifications that become more annoying than useful (assuming the battery hasn’t died first). This time, I wanted something simple and unassuming. Something that tracked my steps, sleep, and fitness metrics properly. No mandatory monthly subscription. No distraction on my wrist. Just useful insight. I’d been looking at smart rings for a while. Oura was the obvious comparison — it looks great — but the ongoing subscription cost and the patent disputes in the US put me off. Then I discovered Ultrahuman. Low barrier to entry The ring sizing kit cost me 10p (or I could have 3D printed one using files from their website). That immediately impressed me. By comparison, Oura charges around £10 for their sizing kit and only refunds it if you go on to buy the ring. Ultrahuman made the entry point incredibly accessible. The reviews were strong, battery life looked reasonable (4–6 days), and the app screenshots looked genuinely useful. Setup & first impressions I purchased the Ring AIR (size 11, brushed titanium) along with the Ultrahuman Ring Voyager charger for faster charging. Everything arrived promptly, and I was set up within minutes. The ring immediately told me it would take around 14 days to fully calibrate to my baseline metrics, but useful data started appearing within the first hour — even in “Chill Mode” (a battery optimisation mode that extends life further). For peace of mind, I also opted for Ultrahuman X (~£50 for 2 years), which covers accidental loss/damage. I know I specifically didn’t want a subscription model, but for an expensive device like this, that felt reasonable and optional. Battery life & comfort The ring is extremely comfortable — I often forget I’m wearing it. Battery life is around 4 days for me, and likely could stretch further. Charging with the Voyager dock is quick and painless — comfortably back to full within two hours. The app experience The app is genuinely impressive — and completely free. There’s a lot of data, which can feel slightly overwhelming at first, but Ultrahuman does an excellent job explaining what each metric means. The longer you use it, the more insightful the reporting becomes (weekly summaries are particularly useful). The app also includes “PowerPlugs” — optional add-ons that extend functionality. Many are free (e.g. Caffeine Window), while some are paid. For example, UltraSync for Tesla provides things like Drive Readiness Score and Drive Stress tracking. I was initially wary that this might be the “hidden subscription model” — but there are far more free PowerPlugs than paid ones, and the core functionality is more than sufficient for most users. It feels optional rather than restrictive, which is the right balance. There are also links within the app to Ultrahuman’s other products (Metabolism, Home, Vision). I was slightly concerned these might feel like constant upsells, but they’re unobtrusive. No annoying ads, no aggressive prompts — and if you owned those products, having everything within one app would actually be preferable to juggling multiple apps. Overall I’m genuinely impressed with the Ultrahuman Ring AIR. It’s comfortable, provides meaningful and well-presented insights, has solid battery life, and - importantly - doesn’t lock core functionality behind a mandatory subscription. It does exactly what I wanted: simple, smart health tracking without the noise. Highly recommended. Five stars from me.

When it worked, it was great, but the battery performance falls off very quickly, and one it does, support is frustrating and tedious. My first one ran fine for about 6 months, and then dropped from 4-5 days of battery life to needing to be charged twice a day in the space of about 6 weeks. The only support was accessible through the app, but insisted on repeated updates of firmware and factory resets with the instruction to "monitor it for 48 hours and come back to us" - this process ran for weeks before I lost my patience and insisted on a replacement. The replacement similarly dropped off in battery performance (and also suffered connection issues, regularly losing all data for several days at a time). Support was once again tedious and frustrating, and an update to the app format has made the support chat less straightforward to access. I'm now told (after multiple factory resets etc) that I'm out of my warranty period, and not elegible for a replacement - despite the app's support tool telling me that I'm eligible for a replacement - although as a goodwill gesture they are prepared to send me a certified refurbished ring. I haven't yet decided whether to accept, as I have already swapped to using an arm-worn tracker instead. The app isn't as slick and the insights aren't as helpful, but at least it stays charged for over a week and retains its connection to the app.

⭐️⭐️⭐️⭐️⭐️ Game-Changing for Biohackers, Fitness, and Recovery! I’ve used nearly every fitness wearable out there, but the Ultrahuman Ring AIR is hands-down the best for anyone serious about tracking health, recovery, and performance. What sets this ring apart is the depth and clarity of its data. It gives me real-time feedback on HRV, sleep quality, skin temperature, and activity in a way that’s actually actionable. Since wearing the ring, I’ve learned exactly how my lifestyle (from hiking and strength training to my daily walks and even supplement timing!) affects my sleep and recovery. The sleep tracking is next-level. The ring doesn’t just tell me how long I slept—it breaks down deep, REM, light sleep, restlessness, temperature changes, and even my body’s recovery rhythm. I was shocked at how accurately it picked up on changes after a heavy workout or even a late night out, and it’s helped me dial in everything from caffeine timing to my bedtime routine. Since using the ring, my sleep scores have improved, and I wake up genuinely refreshed. I love how seamlessly the ring fits into my daily life—it’s light, comfortable, and doesn’t need constant charging. The app is user-friendly, visually stunning, and gives personalized recommendations I actually want to follow. What really sold me is how the Ultrahuman ecosystem ties everything together. It’s not just about steps or calories—it’s about truly understanding your body’s readiness, recovery, and how to push for better results without burning out. It’s helped me break a fat-loss plateau, optimize my training, and finally get those deep, restorative sleep cycles that every biohacker dreams of. If you want to level up your health, perform at your best, and unlock a new level of self-awareness, the Ultrahuman Ring is a must-have. I’m obsessed—and I can’t wait to keep smashing my goals with it. Sleep mask or not, this ring has already improved my life. Highly recommended!

The Ultrahuman Ring AIR is a sleek, lightweight, and comfortable smart ring that provides detailed health and sleep tracking without any monthly subscription fees. It’s easy to wear all day and night and feels far less intrusive than a smartwatch. The sleep and recovery insights are especially useful and have already encouraged me to improve my sleep habits, giving me much-needed peace of mind about my health. Battery life is solid, lasting several days on a single charge, and the app provides plenty of useful data and recommendations, although the interface could be more user-friendly. Some metrics can occasionally feel slightly inconsistent compared to dedicated fitness devices, and the price is quite premium, but overall it’s an impressive and feature-packed health tracker.

As it arrived I was impressed with it. Loved the grey Matt colour , it is so light and after few days it's like a part of your body. Battery lasted 6 days. Lovely look and form . Less steps than on my Samsung watch ,sometimes much to few (Samsung showing 16 000 while ring 12000 only wearing the same time). But it's like dead now .realised I had to daily charge it and after few hours it's gone. Can't get replacement due to third part sale policy and can get refund now. Very disappointed

not recommended the ring worked fine for the first 6 mths then started playing up so i put it in the draw and did not use it the led is not working so it could of been faulty

Good build and decent insights, although the age indicator is way off the mark and is clearly just based on your actual age +/- 3-4 years. But the main reason for the 2 stars is the battery life, I'm having to charge the ring 2-3 times a day, even on the days where I don't exercise. The ring is already in chill mode, background sync off and it's just dropping from 100 to 30% every 4-5 hours. I've had the ring for just over a year now so I expected some battery degradation, but it's almost at the point where it's unusual now. Maybe that's normal, it's the first smart ring I've ever owned, and obviously the battery is very small but I just expected more for the price point.

At first the ring worked perfectly and seemed like a great buy for the price compared to other similar products in the market. However, after just 1 week of use the ring just stopped working. It would not connect to my phone and therefore was rendered useless. I contacted Ultrahuman and they sent a replacement ring out free of charge after quite a bit of back and forth. This next ring worked for about a month and then I had the same issue, not connecting to my phone. I then requested a refund as I was not happy with the quality of the item, great concept but does not work! This is where the real problems started. Ultrahumam agreed to reimburse me for my purchase. However, after weeks and weeks of back and forth, I have still not received a refund. The customer service team have asked me to confirm my bank details 4 times and each time they have said thank you we have sent this across to the relevant team who will process your refund, each time nothing happens and they request my bank details again. The level of service is shocking, they cannot process a simple refund. At this point I do not think I will ever see my refund as the customer service team are totally inept. I would avoid at all cost, unless you want to have a product that works great for only 1 month maximum and never be able to claim a refund if you are unhappy.

1ere mise a jours, la bague ne fonctionne plus. Je suis extrêmement déçu. 3 semaines d'utilisation

It works just fine, the customer service is excellent, size fits alright. The pregnancy mode doesn't really do much apart from telling me how far along I am and which stats can be different... and then the app tells me to pay attention to exactly those stats. Okay.

Ich habe den Ring vor etwa zehn Monaten gekauft und war anfangs wirklich begeistert. Solange der Ring funktioniert, ist das Produkt top. Nach ungefähr sechs Monaten begannen allerdings die Probleme. Mittlerweile hält der Akku nur noch einen einzigen Tag – bei einem Produkt in dieser Preisklasse absolut enttäuschend. Noch schlimmer ist jedoch der Support. Seit über einer Woche bekomme ich nur Standardantworten per Mail: „Ein Supportmitarbeiter meldet sich innerhalb von 48–72 Stunden.“ Dann wurde mir zwischenzeitlich sogar ein neuer Ring angeboten, ich habe zugestimmt – und danach begann wieder das gleiche Pingpong von vorne. Man wird ständig vertröstet, niemand fühlt sich verantwortlich und es passiert einfach nichts. Für einen Ring, der fast 400 € gekostet hat, ist das eine absolute Vollkatastrophe. Produkt gut, solange es funktioniert. Service und Support danach leider miserabel.

La pila dura 2 giorni non 6 le info non sono esatte volevo sostituire L Apple Watch ma non sono riuscito uso di nuovo L Apple Watch

secondo me il miglior ring... purtroppo se lo prendete colorato la vernice si toglie facilmente, però per il resto non ha abbonamenti nè altro di periodico ed è molto sottile
