Oura Ring 4 is the fourth generation Oura Ring, and has a completely new design from the previous generation model. The third generation Oura Ring 3 had an edged appearance, but Oura Ring 4 is completely circular. Also, the inside of the ring was made of epoxy parts up until Oura Ring 3, but the Oura Ring 4 has titanium parts on the inside as well.
In addition, the Oura Ring 3 had a dome-shaped inner sensor that protruded about 1.3 mm, but the Oura Ring 4 has a sensor that is recessed about 0.3 mm. The built-in sensors are a blood oxygen sensor, an optical heart rate sensor, an infrared photoelectric volumetric pulse wave recording sensor, a skin temperature sensor, and a 3D accelerometer. Oura claims that its smart sensing technology with a new algorithm has improved signal quality by 120% and improved the accuracy of various sensors.
In addition, a new feature has been introduced, automatic activity detection, which can recognize and record more than 40 types of activities. Users can check the records on the linked smartphone app. In addition, a function for women has been added, and it is now possible to predict when you may be able to get pregnant.
The updated algorithm has also improved battery life, extending the battery life from a maximum of 7 days for the Oura Ring 3 to a maximum of 8 days for the Oura Ring 4. The nominal time required for a full charge is 20 to 80 minutes.
Sizes range from 4 to 15, and the body comes in six colors: silver, black, brushed silver, stealth gold, and rose gold.
The Oura Ring 4 is priced at $349 (approx. 51,000 yen) for silver and black, $399 (approx. 58,000 yen) for brushed silver and stealth, and $499 (approx. 73,000 yen) for gold and rose gold, and can be ordered from the official website .
