Oura Ring 4
Score: 81/100Rankings
The Fitbit Charge 6 is a slim, lightweight tracker with a bright AMOLED display, built-in GPS and a full suite of health sensors. Its main trade-offs are the mandatory Google account, proprietary charger and lack of an official IP rating. Best suited for beginners to intermediate fitness enthusiasts who value Google services and comprehensive health tracking.
The Oura Ring 4 is a titanium smart ring delivering 24/7 health tracking, including sleep staging, HRV, heart rate, SpO₂ and temperature, with up to eight-day battery life and 100 m water resistance. Its premium hardware is offset by a required subscription for advanced insights and the lack of on-device alerts. Ideal for users who prioritize discreet, high-accuracy health analytics over a free-of-charge experience.
