About this item

Highlights

  • TRY ON THE SIZING RING: It is important to first use the sizing kit to determine your Ultrahuman Ring PRO size. Wear your ring sizer for at least 24 hours to know your fit. Wear the ring such that the engraved size number is toward the palm of your hand.
  • FINDING THE CORRECT FINGER: For optimal comfort and advanced sleep tracking, we recommend that you wear the Ultrahuman Ring PRO on your index, middle, or ring finger.
  • FIT CHECK: You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring PRO. Here are a few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely.
  • CHOOSE YOUR RING: After you've precisely determined your size using the sizing kit, head over to Amazon to order your Ultrahuman Ring PRO.
  • BUILD QUALITY: While the sizing kit is made of high-grade plastic, the Ultrahuman Ring PRO stands leagues apart in its material composition. Crafted from space grade titanium with a unibody architecture, your Ultrahuman Ring PRO promises superior quality and long-term durability.
  • PICK YOUR COLOR: Once you know your size, you can now choose the color of your Ultrahuman Ring PRO from the swatch card provided in the box. The swatch card showcases all 4 color variants, find the perfect match for your style.

Great fitness tracker device on the finger!

[This review was collected as part of a promotion.] I bought this product a few months ago and have really loved it. What I especially appreciate is the sleep score and the way it provides personalized suggestions to improve sleep and recovery. The stress tracking and insights are equally helpful.

Ultrahuman - Absolute Beast

[This review was collected as part of a promotion.] The Ultrahuman Ring PRO has been one of those decisions in my life which I won't regret. I have been using it for the last 1 month and everything is on point. The health tracking, the battery, the UI everything. Most importantly, it is very efficient and easy to understand and UH has difinitely improved a lot of things from the Ring Air to Ring Pro.

My Experience with the Ultrahuman Ring PRO

[This review was collected as part of a promotion.] The Ultrahuman Ring PRO has been a great addition to my everyday routine. What I like most is that it goes beyond simply tracking activity and gives a much more complete picture of sleep, recovery, movement, and overall wellness. The sleep and recovery insights are particularly useful because the data is presented in a way that is easy to understand and act on. I also really like the Ultrahuman app, which makes it simple to follow trends and understand how my daily habits are affecting my recovery. The PowerPlugs are another feature I really appreciate. They add useful, focused insights without making the experience feel complicated. The overall combination of the Ring PRO, app, and PowerPlugs makes it feel like a genuinely connected health-tracking ecosystem rather than just another wearable. The ring itself is sleek, comfortable, and easy to wear throughout the day and night. Overall, the Ring PRO has been a very impressive experience, especially for anyone looking for a wearable that focuses on long-term health, sleep, and recovery rather than just counting steps.

(no review title)

I've been using the Ultrahuman Ring Pro, and it has genuinely elevated my approach to tracking personal health metrics. A single charge lasts up to an impressive 15 days, supported by a premium, highly durable charging case. Outstanding data accuracy and robust build quality ensure you get consistent, dependable health insights. And extremely lightweight and comfortable for continuous 24/7 wear, making daily health monitoring completely frictionless.

Better features and great battery life

I’ve been wearing the Ultrahuman Ring Pro for a while now and honestly, it’s been a nice step up from the Air. The battery lasting around two weeks (and even longer with the case) is the biggest win for me — I barely think about charging anymore. The titanium build feels more solid, the heart rate tracking seems cleaner at night, and having weeks of data stored on the ring itself is really convenient. The app is still solid with all the main sleep and recovery stuff included for free, and I only add the PowerPlugs I actually care about. It’s comfortable enough that I forget I’m wearing it most of the time. Overall I’m happy with it. If you liked the Air but wanted better battery and a bit more refinement, this feels like a worthwhile upgrade.
