Ultrahuman’s Ring Pro is a smart fitness tracking ring that weighs between 3.3 and 4.8 grams (about 0.1 oz) (available in sizes 5 to 14. The company’s first major hardware update since 2023 is the Ring Air, and it’s been redesigned from the ground up. which saw it controversially banned from sale in the US. Second, the company realized it had done everything it could with the Spirit and needs to increase the processing power of the ring Pro has improved the silicon to hopefully provide many new details.
As a result, the new model comes with a dual-core chip with built-in machine learning and 250 days of internal storage. That’s a big jump from the Air’s single-core unit that had just four days of memory to keep track of your essentials. Ultrahuman hopes that Jade, the company’s new AI, will be able to dig deeper and draw more conclusions based on these long historical trends. Also, the company expects to be able to introduce a wider variety of Power Plugs – paid add-ons designed to monitor specific statistics – as the ecosystem grows.
It’s immediately clear that the Pro is a different beast to the Air, made with an outer ring of titanium and an inner epoxy resin. When you looked down at your finger on the side of the ring you saw two things together. The Pro is clad in titanium inside and out, except for the resin section that houses the PPG sensors. If you’re the type to remove your calipers, you’ll find the Pro is 0.25mm thicker than its predecessor. But the whole titanium body does to hear it’s much chunkier. I didn’t notice a noticeable difference while wearing it, but people have sharper digits than mine.
As for tracking, you’ll get a temperature, motion and PPG sensor that the company says has been redesigned for better accuracy. Given that pretty much all the laws of physics will allow you to wear a smart ring these days, there’s not much to say about it. After all, it’s not the data you collect but the information you can generate from it that matters. Battery life is limited to 12 days in “Turbo Mode,” but you can extend that to 15 days or more with “Cooling Mode,” which reduces the amount of tracking to extend longevity.
The Ring Pro does not charge wirelessly. Instead, it uses a portable pin on the charging case to reduce the thermal problems caused by wireless charging. The ring itself is also designed to open easily to free your finger quickly if the battery starts to swell. Naturally, it’s rare for a wearables company to talk about these things, so Ultrahuman deserves props for being the first to do so.
I suspect people will want a direct comparison between the Ring Pro and Oura 4. Depending on the size of your finger, they’re both a shade under 3mm (0.1 inch) thick and almost indistinguishable. Up close, the silver titanium of the Oura is more shiny than the titanium green found on the Pro, but that’s about it. The only real difference is in the less visible sensor position of the Pro or the positioning notch of the Oura.
