Oura

Oura pioneered the smart ring category, packing advanced health sensors—tracking sleep, resting heart rate, HRV, and temperature—into a lightweight, screen-free titanium band. Serving as the definitive European alternative in biometric wearables, it provides a highly focused, distraction-free alternative to notification-heavy American and South Korean smartwatches like the Apple Watch and Samsung Galaxy Ring.

Independent and privately held, heavily backed by both European and US venture capital.
