Overview

The Ultrahuman Sizing Kit comes with 10 high-grade mock rings to help you find the perfect Ring size. It is the only Sizing Kit that comes with true-to-life colors to help you visualize your preferred Ring color.

Size first before you buy
Ultrahuman Ring sizes differ from standard ring sizes. Purchase a sizing kit first to get the perfect ring AIR size. Ring AIR is available in 10 sizes from 5-14.

Trying the sizing ring
It is important to first use the sizing kit to determine the Ring AIR size. Wear the ring such that the engraved size number is toward the palm of your hand.

Take the two night test
Wear the Ultrahuman Sizing Kit ring over two nights or 48 hours to find your fit. This is an important step in understanding your ring size. The perfect ring size ensures that you have the most accurate readings.

Fit check
You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring. Here are a few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely.

Finding the correct finger
For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger.

Color choice
With the true-to-life color swatches, you can visualize and pick the color you like.

Choose your ring
After you've precisely determined your size and preferred color using our sizing kit, head over to Verizon to order your Ultrahuman Smart Ring.

Build quality
While our sizing kit is made of high-grade plastic, the Ultrahuman Ring is crafted from space-grade titanium and coated with tungsten Carbide, your Ultrahuman Smart Ring promises superior quality and durability.

[This review was collected as part of a promotion.] Stopped sending data to my app after about 2 months of use and the battery dies after a few hours - doesn’t last a full night. I tried resetting it, followed all of the prompts, but nothing will fix it. Basically completely useless and a total waste of money.

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] I’ve had my Ultrahuman Ring for almost a year now, and I’m still really enjoying it. It’s given me a lot of insightful data that’s helped me better understand my sleep patterns, identify foods my body doesn’t agree with digestively, and even recognize when my immune system might be compromised. The insights have made me much more aware of how my body responds to different habits and routines. And one of the best parts is that all of this comes without a monthly subscription.

Excellent sleep and cycle tracking!

Zombialinka . 4 months ago

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] I've been using the ring for over half an year now and Im super happy with it. The activity tracking for sports could be better but since I tend to use a sekretem device for this im not too bothered. Sleep tracking is excellent but I think cycle tracking was the biggest game charger for me. I never rememberd to track my cycle and now that ist done pretty much automatically I've started connecting my symptoms to my cycle and discovered my healh issues are due to perimenopause. The data collected made it so much easier to advocate for myself with my health provider! No subscription is also key here!

Got other wearables before

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] I used many other wearables in the past, but was impressed by the Ultrahuman Ring Air. A big plus for me was its affordable, subscription-free price. Initially, it was the practical form factor that attracted me, and pairing capabilities with the most popular smart watches and iOS and Android phones. Easy to wear, fashionable, super light, and comfortable to wear all the time. No need to remove around water, thanks for being waterproof. I discovered a new world of advice on better health and well-being. Impressed by the sleep, stress, cardio reporting, AFIB, recovery, and brain age, stress management data, and amused by the accurate caffeine window. Not perfect but improving daily, with WhatsApp 24/7 customer service when needed.

Best smart ring in the market

GurkGill . 4 months ago

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] The Ultrahuman Air Ring has become one of my favourite health gadgets. It feels like nothing on my finger, the build quality is excellent, and the recovery/sleep data has genuinely helped me make better training decisions. The app feels smarter and more intuitive than most wearables, and the daily insights are actually actionable. If you care about recovery without wearing a bulky watch 24/7, this is a no-brainer.
