OUR VERDICT
Polar

Best for: Endurance runners and triathletes who want workout-focused accuracy and are willing to skip smartwatch extras like an app store.

Oura Ring

Best for: Someone who wants sleep and recovery tracking without a wrist device, and doesn't mind a small monthly fee for the full app experience.
