ULTRAHUMAN Ring AIR (Certified Renewed) – Smart Tracker for Men/Women, Fitness and Sleep (Sizing Kit)

I can genuinely say that this Smart Ring has changed my life in so many ways. The Ring tracks so many different areas including stress, caffeine intake and its effects, shift work, sunlight exposure, exercise etc. The app is seamless and very well laid out, not only provided the data but giving you real tips and advice on how to make improvements. I do not know if the data displayed is 100% accurate but it gives a baseline to work with and the data then shows trends including body temperature and movement during my sleep. I do not wear my Apple Watch Ultra to bed as it is too bulky and needs charging so the Ring is perfect. Battery lasts around four days, but I charge it when not wearing it for weight lifting to avoid damaging it. The Ring feels super high quality and hasn't yet marked despite continued use in a variety of activities. It is also really light in weight so you don't even notice it and is not bulky. I went for the dark grey titanium colour and it looks and feels more premium than I expected. I got the Ultrahuman X subscription with the Amazon offer and is really worth the extra upgrade for peace of mind, also brings a new feel and look about the app with enhanced features. I had to contact Ultrahuman support via the app to help activate the code and they were really friendly and so fast to respond to message through the chat. Cannot recommend this Ring enough, especially at the price an official refurbished one is on their store through Amazon.

I’ve been using the Ultrahuman Ring Air for a few weeks now, and I’m genuinely impressed. It’s lightweight, super comfortable (I barely notice it’s there), and the build quality feels premium. What really sets it apart, though, is the depth of insights it gives me. The sleep tracking is spot-on, and the recovery and movement metrics have actually helped me make better choices day-to-day. The app is beautifully designed and easy to understand — it doesn’t just throw data at you, it interprets it in a way that feels actionable. Battery life has been great too; I’m getting almost a week per charge with regular use. I’ve used other fitness rings before, but the Ultrahuman Ring Air feels like a step up — both in comfort and in the quality of feedback. It’s stylish enough to wear all the time, and it’s genuinely motivated me to be more mindful about my health. Highly recommended for anyone looking to upgrade their wellness tracking without compromising on style or comfort!

I’ve been using my Ultrahuman Ring Air for just a couple of weeks now and I'm happy to say that I really like it. I like how it works, the insights it provides and the ring itself. The app is very detailed and tracks a lot of information, which I’m still getting used to and learning how to fully understand. Sleep tracking was my main focus and so far it’s been really impressive. The ring itself also does a good job of calculating my steps. I wore my Fitbit alongside it for the first few days to compare the difference and I was pleased with how accurate the ring was. I love the overall design as it’s super sleek and blends nicely with my other jewellery. I’d definitely recommend using the sizing kit before buying. I’m glad I did, as my ring fits well (size 7). My finger does expand and shrink throughout the day, so it can feel slightly loose at some points, but aside from that the overall fit is good and I am able to wear my ring on both my pointer and middle fingers. Overall, I highly recommend buying this! I bought mine during the Black Friday sale, which was a great time to get it as I saved a lot of money in the end!

Pros: Incredible insights especially on sleep quality and metrics. app interface is immaculate Ring is so lightweight I forget I'm wearing it. Cons: it's a bit bulky in comparison to rival brands but it doesn't bother me. Battery could be better. Needs charging on chill mode every 4 days on average.

The ring came nicely packaged and was very easy to connect to the app. Only used it for 1 day and I am very impressed. The amount of data this thing can create and the analysis it does such as the caffine window for optimum time to have a coffee, sleep, movement and recovery scores are some of the many data sources the app populates. Very easy to use and since using it yesterday I have walked more than I normally wood. I have a Apple Watch Ultra, but this app is so much better it tracks when it knows you are moving around and gives you an option to track it, as the watch does not always pop up to suggest if you are doing a workout. The battery was a bit strange I fully charged it (the charging light went off after flashing) but the app said it was not fully charged. I contacted their support and they promptly sent the latest firmware update directly to the ring, just had to restart the app on my phone and it was then showing the correct batter percentage. Overall its brilliant so far, looks very slick, well built and very good value for money even though it is renewed, it looks perfect. Very happy with this purchase (with the free 2 year warranty extension too).

I’ve been using the Ultrahuman Ring for a few weeks now, and I’m genuinely impressed by how much insight it gives into my health without feeling intrusive. It tracks sleep, recovery, and activity with remarkable accuracy, and the data actually means something - it’s not just numbers on a screen. The best part for me has been the sleep and recovery tracking - I’ve realised how small habits (like eating too late or using my phone before bed) affect my readiness the next day. The app breaks it all down in a way that’s simple but science-backed. It also feels premium - sleek, comfortable, and barely noticeable. I wear it 24/7 and honestly forget it’s there.

prodotto top per avere su un dito la propria salute.

I could not live without my Ultrahuman ring! It is the perfect alternative to bulky fitness watches, and tracks even more. I read a lot online about the battery, but I have had no issues. It lasts 5-6 days on a full charge. The customer service is also amazing and readily available for any questions!

Llevo tan solo unos días con el anillo pero por el momento muy contento con los datos que recoge y la información que presenta. Eso sí, la app por el momento no está totalmente traducida al español y a veces mezcla frases en inglés pero me imagino que será algo que se corrija. Yo soy una persona que no llevo anillos y las primeras horas con él me sentía algo raro pero ya me he acostumbrado y no me molesta nada. Es cierto que es algo ancho y grande pero estéticamente me parece un anillo sencillo pero bonito. Parece mentira la tecnología que lleva incorporada dentro de un anillo tan pequeño. Estuve mirando otros anillos de otras marcas pero finalmente me decanté por este por dos razones: Precio muy competitivo en un producto revisado (que en realidad está como nuevo). No tener que pagar una suscripción mensualmente para tener los datos.
