Beautifully packaged ring sizers to ensure perfect fit before purchasing Ultrahuman ring. Great communication and efficient design.

Der Ultrahuman Ring überzeugt mich durch sein elegantes, unauffälliges Design und die sehr präzisen Gesundheitsdaten. Schlaftracking, HRV und Aktivitätswerte werden übersichtlich dargestellt und helfen mir, meinen Alltag bewusster zu steuern. Besonders positiv finde ich, dass kein Abo nötig ist und der Ring angenehm leicht zu tragen ist – auch nachts. Die App ist klar strukturiert und liefert sinnvolle Insights ohne zu überfordern. Insgesamt ein hochwertiges Produkt für alle, die ihre Gesundheit datenbasiert verbessern möchten.

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!

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 AIR for a while now to track my daily activity and sleep, and it has genuinely changed how I approach my routine. As a "Certified Renewed" product, I was pleasantly surprised that it arrived looking brand new and has functioned perfectly. What I love about it: - Easy to setup and is waterproof. - Decent battery life (3-4 days). I usually just charge for 15 minutes every day when I'm at my desk. - It does an incredible job of recording sleep stages, movement, and recovery metrics like HRV and heart rate. Having all this data on my finger instead of a bulky watch is much more comfortable for 24/7 wear. - A "Sleep Quotient" or "Recovery Score" every morning. I’ve found that seeing an "unsatisfactory result" really acts as a psychological motivator to get to bed earlier the next night. It’s almost like a gentle punishment that holds you accountable for your habits. - It’s a good fit and so lightweight that I often forget I’m wearing it. Final Verdict: If you want deep health insights without a monthly subscription fee, this is a top-tier option. It has definitely helped me stay more disciplined with my bedtime. I highly recommend picking this up, especially if you can catch it on sale or as a renewed unit for the extra value!
