Review: Finally a wearable that does what I actually want — without the subscription trap - 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.
Review: Great idea, badly implemented and let down by poor quality control and battery technology - 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.

### ⭐⭐⭐⭐ Review after wearing the Ring Air everyday for 9 momths
*by G***E on 2 October 2025*

I really like my Ultrahuman Ring Air, love the data it collects and shows, I love the fact you get stacks of data and don’t need to subscribe to an app. Kudos to them. Also kudos for their support team and rapid response via WhatsApp chat. I wear it everyday, after nine months the resin on the inner ring started peeling, then it wouldn’t charge, no worries they sent me a new one with no quibble (luckily I still had proof of purchase!, screenshot of Amazon purchase history!) a couple of niggles though. Ring size of actual ring is definitely different to the plastic sizing ring, so I wear it on my middle finger not my intended forefinger, no biggie really. I’ve never had anywhere near 6 days battery life, maybe four days at best and only then when on low power mode. For the warranty exchange they asked me if I had been scuba diving, why ask that(?), the blurb says it’s good to 100m!, no PADI AOW diver gets anywhere near that depth, anyways I said no only sea swimming and snorkelling and I got my exchange approved. I highly recommend this gadget, saves wearing a smart Watch or a Fit-bit type gadget. Everyday use including sailing in all weathers, swimming in the sea (and ‘cough’, maybe some scuba diving 😉) it lasted nine months, like I said it was exchanged no charge no quibble but longevity may be an issue as these things are not cheap if I had to repurchase (original was a milestone birthday gift!).
