This is the first time the Oura Ring 4 has gone on sale, making it an especially attractive option.

Best Ring for Samsung Fans: Samsung Galaxy Ring
The Samsung Galaxy Ring (7/10, WIRED Recommends) is a sleek and lightweight smart ring offering accurate sleep, workout, cycle, and heart rate tracking. While optimal performance requires a Samsung watch or phone, the seamless integration within the Samsung ecosystem is a significant advantage.
