Interest in smart rings is rapidly growing, but the question remains whether the Oura Ring 4 truly differs from other similar devices. The author conducted a month-long test of the Oura Ring 4, examining its functions, including sleep tracking, Readiness Score, activity monitoring, stress control, body temperature trends, and other health parameters.
The Oura Ring 4 is capable not only of recording sleep and activity but also of analyzing changes in bodily patterns, providing the user with early signals regarding their health. This means that when the body deviates from the norm, the first signs may appear in the ring's data.
However, an important question arises: is the purchase of the Oura Ring 4, priced over 30,000 rupees, justified? The necessity of subscribing to the device is also discussed.
