Oura Ring 4 unveiled: Meet the sleeker, more accurate smart ring

Oura has just unveiled its fourth-generation smart ring, introducing several upgrades to its popular wearable. The Oura Ring 4 costs a bit more than the previous version. However, thanks to its slimmer profile and new features, it’s still as portable and comfortable as before and offers higher accuracy. Starting October 15, shipments will be headed your way, starting at $349 for the revamped model, now available for preorder.

The Oura Ring 4 sports recessed sensors, creating a smoother interior that eliminates raised bumps like you experienced in previous models. This change makes the ring’s readings better at both comfort and accuracy. In its claim, Oura says it has a 30 percent increase in accuracy of SpO2 measurements and better heart rate measurements, with a 7 percent reduction in data gaps throughout the day and 31 percent fewer gaps at night. While they recessed the sensors, Oura continued to stress that the device had become more accurate overall.

Oura Ring 4 has improved sensor tech: accelerometers and photoplethysmography sensors that measure heart and respiratory rate. The ring also tracks blood oxygen, cycle tracking, cardiovascular age, and stress. This includes its long battery life, now up to eight excellent days between charges.

One of the previous models’ limitations is addressed by the expanded ring sizes to fit a wider range of users (4 to 15). It also comes in six colors, including the new “deeper black look,” ensuring both aesthetic appeal and functionality. The ring’s light titanium build remains, incorporating weight and durability balance as the ring weighs between 3.3 and 5.2 grams, depending on the size.

Oura also continues to innovate with software and hardware updates. Oura Labs will now be available to Android users as the company’s platform for experimental features. Within the Oura app, the new Aura Advisor feature takes AI to the next level, using health data and tailored guidance for the user to reach their health goals. Another feature called Symptom Radar sends them early warning when they risk getting sick.

And Oura’s newly redesigned app showcases their dedication to user experience. It now features three main tabs: Vitals and My Health, which offer flat UI and deep, in-depth data about the biometric data.
The Oura Ring 4 represents the same experience you know and love, but in a slimmer shape, with improved accuracy and a wider range of sizes to fit a wider range of users.
