## Description

ULTRAHUMAN Ring AIR - Bionic Gold - Size 9 - Smart Ring | No Monthly Subscription | Size First with Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker : desertcart.co.uk: Sports & Outdoors

Review: best smart ring on the market! - best investment of 2025! looks and feels amazing on, very functional - you can track so much on it in real time. especially good if you struggle with sleep as it gives you detailed insights. i managed to get it on a black friday deal (£232) so the value for money was amazing! only con of this ring is that it does scratch easily but this can be mitigated by getting a cover for it.
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.

Through multi-biomarker-based tracking for those looking to conceive, predict a 7-day fertile window and pinpoint ovulation with precision. Access cycle tracking combined with biomarker-based personalized guidance for every phase (Menstruation, Ovulation, Follicular, and Luteal). With Pregnancy Mode, expecting mothers get tailored pregnancy insights throughout each trimester.
- ONE APP, NO SUBSCRIPTION: Enjoy all the essential standard features of the Ultrahuman Ring, including sleep, activity, stress, heart rate, heart rate variability, skin temperature and recovery with no subscription — on the Ultrahuman App.

### ⭐⭐⭐⭐ So far so good....
*by G***. on 26 December 2025*

So far so good. Ring functions well with a few caveats. The times showing wake up etc are generally inaccurate. For example today I was up at 0458 and the ring indicated 0809. This then throws off some of the other stats. Additionally, I would like some more explanation or simplification of the stats and figures in the app as I am quite new at this. The ring looks good but come off periodically while I am doing things around the house. Perhaps I should have sized differently but wear it on my index finger by choice. May have to replace it for different size. Generally I am satisfied but would really like a less complex app UI for us newbies. Will update after further usage.
