The Oura Ring 4 has a new design, an updated app, and improved accuracy, as the company pushes to maintain its status as the smart ring to beat.
Following the release of various other new smart rings this year, Oura has announced the Oura Ring 4, the latest generation of probably the best-known smart ring. It comes with a wide range of changes and new features, plus a brand new design.
Related The Oura Ring 4 is made of titanium, and this time, the metal extends to the underside of the ring, replacing the epoxy resin used for the previous-0generation models. The dome-like 1.3mm-high nubbins have been removed, and the sensors are practically flat at 0.3mm high, increasing overall comfort. The Oura Ring 4 weighs between 3.3 and 5.2 grams, is 7.9mm wide, and is 2.88mm thick. It’s now available in more sizes, ranging between size 4 and size 15.
“We designed five years ago because of their usefulness for accuracy, and we’ve seen many smart ring makers leverage that same design. You also see some that don’t utilize those domes, which really comes at the expense of accuracy. We’re not willing to sacrifice accuracy, and that’s what’s really remarkable about as we’ve lowered the domes, not just while maintaining accuracy, but actually making a huge leap forward using a revolutionary new sensing platform called Smart Sensing.
There are three tabs along the bottom of the app: Today, Vitals, and My Health. Notably, shortcut tabs along the top of the Today screen show familiar Readiness, Sleep, Activity, Heart Rate, Stress, and Menstrual Cycle scores, while the main section below shows current biometrics and progress toward your goals. The Vitals screen provides more in-depth data, while the My Health screen has long-term health metrics such as Stress Resilience, Cardio Age, and ongoing trends.
