Oura Ring 4 is a new version of the series smart rings from a manufacturer that has so far dominated this innovative market. But the entry of a giant like Samsung and its Galaxy Ring can undoubtedly change the playing field.

And here comes the new Oura, which Samsung certainly had in mind during development. Or maybe that’s why. Its functions continue to focus on the same as a quantifying wristband or smart watch, a device for monitoring, measuring, tracking and recording information related to health, fitness and sleep.

Oura Ring 4, (almost) the same but improved

The new version greatly enhances the experience of previous generations, rather than reinventing it. And a ring is still a ‘ring’ with limitations in size and design. Nevertheless, the company managed to get slimmer profilesomething to the price, because version 3 was already extremely compact.

The ring is made in titaniuma light and durable material that makes it possible to achieve a weight similar to a standard ring. It is available in a wider range of ring sizes, from 4 to 15, and will be available in six different colors, including “deeper black”.

The big difference is inside the ring, as the sensors that were previously raised are now recessed, creating a a more consistent and hopefully more comfortable experience. Although the sensors are more hidden on the finger, the new ring collects more accurate data than previous models. The new version includes an accelerometer for movement; Green, red and infrared LEDs for measuring heart and breathing rates; and a temperature sensor.

It is worth noting that the Oura Ring 4 is able to measure blood oxygen levels. Overall, the system can collect several dozen metrics, including more complex datasets such as cycle tracking, cardiovascular age, and stress levels. The company claims to have improved the signal quality for blood oxygen detection by 120%, which translates to a 30% increase in the accuracy of the average overnight SpO2 measurement.

One of the advantages of the type of passive tracking that this smart ring does is that it uses much less battery. The Oura rings have always had great battery life and this one increases the autonomy up to eight days and eight nights on one charge.

Oura Ring 4 is now available for pre-order. In Spain, it is available on its web portal in the mentioned six finishes, from the basic ones in gray or black with a price 399 euros. The gold version costs 549 euros. Buyers will have access to a free monthly subscription to the Oura software service. The company will keep the third-generation ring until current supplies run out.
