Smart ring company Ultrahuman made its grand return to the US market on Tuesday, following a patent dispute with rival Oura that locked it out of the country since late 2025. Now, US Customs and Border Protection has cleared the company to operate in the US, and its newly announced Ring Pro is available to preorder immediately.

Back in August 2025, the US International Trade Commission ruled in Oura's favor in a patent dispute against both Ultrahuman and Ringconn over the internal architecture of their rings. Ringconn reached a royalties agreement with Oura, but Ultrahuman instead stopped selling its Ring Air while it worked on the design of Ring Pro. At the end of February, Ultrahuman unveiled its new creation and began selling it globally while awaiting US clearance.

That clearance has now come through, allowing Ultrahuman -- which, along with Samsung, has the second-biggest market share of the smart ring market after Oura -- to tempt American buyers with its wearable tech once more.

"We're delighted to be back in the US with Ring Pro," said the company's CEO, Mohit Kumar, over email. "Ultrahuman is an engineering company -- and we believe that the company that leads with engineering will ultimately win in this space."

If you've been considering taking the leap into the world of smart rings, Ultrahuman's Ring Pro has several compelling features that make it worth considering. First up is the astonishing 15 days of battery life on a single charge. This can be expanded to more than 45 days with the Pro charging case.

Ultrahuman, unlike Oura, also doesn't charge a subscription fee to access key health data, including sleep, recovery, movement, stress and circadian data (although some advanced metrics, available as software plugins, do require a subscription). The ring packs a redesigned heart-rate sensor, a dual-core processor for on-chip machine learning and 250 days of on-device health data storage. It's designed to free you from being constantly tethered to your phone.

The first 1,000 customers to preorder the Ring Pro will get the ring and charging case for $349. After preorders, the Ring Pro will be priced at $399 and include a mini charger, with the charging case costing $100 (or you can buy them as a bundle for $479). It's available in black, silver, gold and titanium, and features technology that allows it to be easily cut apart in case of accidents or finger swelling.

Ultrahuman is leveling up

Ultrahuman says it's returning stronger than ever to the US -- and not just because of its new ring. When I dropped by the company's booth at CES this year, I was impressed to see how the company had grown into a more well-rounded, holistic health company than it had been even 12 months earlier.

Not only has it launched a home device to ambiently monitor your sleeping environment, but it's expanded into cutting-edge ovulation tracking, on-ring AFib detection, FDA-approved migraine insights and real-time glucose monitoring through a separate wearable sensor. Ultrahuman now also performs blood tests that assess your biomarkers for a wide range of issues through its Blood Vision service.

Even without any rings on display, it was a show of the company's commitment to being not just a rival to Oura but a leader with its own fresh ideas in the burgeoning health tech space. 

Ultrahuman currently has around 9% of the smart ring market compared to Oura's 74%, according to a report from Omnia last November. But with the market continuing to expand, there's plenty of room for it to keep winning over new customers.
