The Ultrahuman Ring Pro is now in US stores, at Best Buy and Amazon, for $479. Ultrahuman announced it in February and opened US preorders in March. It reached shelves in the last week of October.

Oura won a patent fight in 2025 that kept the Ring Air, the Pro's predecessor, out of US stores. So the Ring Pro got a new unibody shell built to steer clear of Oura's patents. Mohit Kumar, Ultrahuman's founder and chief executive, said earlier this year that the company took the design through US Customs and came away with an order calling it non-infringing. Oura has since sued again over two different patents, but the ring stays on sale unless a court says otherwise.

$479 is $79 more than the cheapest Oura Ring 5. The gap closes because of the subscription. Oura charges $5.99 a month or $69.99 a year, and Ultrahuman's core features cost nothing extra, so the Ring Pro comes out cheaper after about 14 months. The price includes a charging case. There are four finishes, gold, silver, black and titanium, in sizes 5 to 14.

The shell also carries what Ultrahuman calls ProRelease, a design that lets paramedics or doctors cut the ring off quickly, for example if the battery swells.

Dan Bracaglia, who has worn one for a few days for Tom's Guide, weighed his size 11 at 4.52g, against about 2.5g for a comparable Oura Ring 5. The band is 2.6mm thick and about 4.8mm at the sensors. That makes it thicker and heavier than most rings he has tried, though after a day on his index finger he said he hardly noticed it.

Ultrahuman rates the battery at up to 15 days. Oura promises up to nine for the Ring 5, and Bracaglia puts real use closer to seven or eight. The metal case holds two full recharges. That's up to 45 days away from a wall socket, by Ultrahuman's count. The case also updates the ring's firmware and buzzes or beeps when charging is done.

Inside, Ultrahuman reworked the heart rate sensor and added more processing power for heart, sleep and recovery readings. The new chip can also run machine learning on the ring itself. The shell also carries what Ultrahuman calls ProRelease, a design that lets paramedics or doctors cut the ring off quickly, for example if the battery swells.

Bracaglia's full review is still to come, and heart rate accuracy and that 15-day figure are what he plans to test. For anyone who'd rather not pay Oura every month and doesn't mind a thicker ring, the Ring Pro is now a box on a Best Buy shelf rather than a preorder.
