Ultrahuman's $479 smart ring with no subscription is now sold in US stores

Ultrahuman's Ring Pro, a smart ring that tracks your health without a monthly fee, is now on sale in the US. It costs $479 and sells at Best Buy, Target, Walmart and Ultrahuman's own website. The launch comes with a catch. Rival Oura filed a new patent complaint six days earlier, seeking another US ban.

What it does

The ring tracks heart rate, heart rate variability (how the timing between heartbeats shifts), skin temperature, sleep, movement, stress, recovery and your circadian rhythm, which is your body's daily cycle. None of that requires a subscription. Optional add-ons called PowerPlugs cover things like respiratory health, cycle and ovulation, vitamin D and headaches. Some are free. Others cost up to $6.90 per month.

Battery and extras

• Battery lasts up to 15 days on one charge.
• The Pro Charging Case stretches that to at least 45 days.
• The ring stores up to 250 days of data, so it does not need constant syncing.
• It comes with a one-year warranty.
• Sizes run from 5 to 13, in four colors.

Ultrahuman also offers an AI assistant called Jade that uses your health data to give personalized guidance. CNET advises caution when trusting any company or AI tool with health information.

Where to buy it

The ring is available now at 300 Best Buy stores. In the coming weeks, it will roll out to more than 1,000 Target and Walmart stores. That means shoppers can try one on before buying.

What testing showed

CNET writer Vanessa Hand Orellana has tested the ring for months. She says its main advantage is the no-subscription setup, with the main features not locked behind a paywall as with Oura. She also notes the battery life is twice that of other smart rings.

There are downsides. The ring is thicker than the Oura Ring 5 and more prone to scratches. Automatic workout detection needs work. Heart rate readings during workouts are not reliable unless you pair the ring with a third-party device.

The legal fight

Ultrahuman has been through this before. In August 2025, its earlier ring, the Ring Air, was banned in the US after a US International Trade Commission ruling. Oura had filed that complaint in March 2024. The new complaint covers patents that were not part of the first one.

Ultrahuman unveiled the Ring Pro in February and received US Customs and Border Protection clearance a month later. A spokesperson says the court has not ruled on Oura's latest complaint, so the company will keep making and selling the ring in the US. It says it will defend its position vigorously. Whether another ban follows is not known yet.
