The third-generation Ring Pro packs a 15-day battery (way longer than most), a dual-core processor for on-device smarts, and an upgraded PPG sensor for better sleep and recovery tracking.
It's made from titanium, comes in four colors (Bionic Gold, Space Silver, Aster Black, and Raw Titanium), and fits sizes 5-14.
The PRO Case adds 45-day power backup and supports Qi wireless charging.
Early US pre-orders start at $349 (shipping May 15), then they go up to $399.
About 2.6 million smart rings were sold in the US in 2025, but Ultrahuman has been losing ground to Oura, which now owns 85% of the market there.
The CEO is aiming for a comeback within six months, just as Oura has launched its Ring 4 in India.
