Ultrahuman’s Ring Pro is a smart fitness tracking ring that weighs between 3.3 and 4.8 grams (about 0.1 ounces) (available in sizes 5 to 14. It’s the company’s first major hardware update since 2023’s Ring Air, and it’s been redesigned from the ground up. Two things prompted the change: First, the Ring Air infringed on a patent owned by Ora, which controversially blocked it from sale in the US. Second, Realizing that it had done everything it could with the Air and needed to radically increase the processing power of the Ring, the Pro has upgraded the silicon to provide lots of new insight into the future.
As a result, the new model comes with a dual-core chip with onboard machine learning and 250 days of internal storage. This is a huge leap from the Air’s single-core unit that only had four days of memory for tracking your vitals. Ultrahuman hopes that Z, the company’s new AI, will be able to dig deeper and draw a lot of conclusions based on these longer historical trends. Also, the company hopes that as the ecosystem matures, it will be able to launch a wider variety of paid add-ons – Power Plugs – to monitor specific statistics.
It’s immediately apparent that the Pro Air is a different beast, built with a titanium outer ring and an epoxy resin interior. When you looked down your finger at the edge of the ring you could see both materials together. The Pro is covered in titanium inside and out, except for the resin section that houses the PPG sensor. If you want to swap out your calipers, you’ll find that the Pro is just 0.25mm thicker than its predecessor. But the all-titanium body makes it feel Too thick. I didn’t notice any significant difference while wearing it, but people with more beautiful figures than me might have to wear this.
For tracking, you’ll get temperature, speed, and a PPG sensor that the company says has been redesigned for better accuracy. Given that almost all the laws of physics will allow you to incorporate them into a smart ring these days, there’s not much else to say about them. After all, it is not the data you collect but the insights you are able to generate from it that is important. Battery life is rated for 12 days in “Turbo Mode,” but you can extend that to 15 days with “Chill Mode,” which reduces the amount of tracking to increase longevity.
The Ring Pro does not charge wirelessly. Instead, it uses a physical pin connection on the charging case to reduce thermal problems caused by wireless charging. The ring is also designed in such a way that it can be easily cut open so that your finger can be quickly freed when the battery drains rapidly. Naturally, it’s rare for a wearable company to talk about these things, so Ultrahuman deserves support for pushing it forward.
I suspect people will be looking for a direct comparison between the Ring Pro and Oura 4. Depending on the size of your finger, they are both less than 3 mm (0.1 in) thick and virtually indistinguishable. Upon closer inspection, the Ora’s silver-coated titanium is a little shinier than the raw titanium found on the Pro, but that’s about it. The only real differences are in the Pro’s slightly more visible sensor zone or the Ora’s orientation notch.
