What to expect from the Oura Ring 4

Oura has largely dominated the smart ring market since its inception, but new players have entered the field, muddying the waters somewhat. Tech giant Samsung recently released its own smart ring, the Galaxy Ring, offering serious competition for Oura. Adding to the pressure is the fact that it released the Oura Ring 3 three years ago, which, in the tech world, equates to a nearly geriatric product.
