Which should you choose?
Choose a smart ring if your priority is sleep, recovery and all-day comfort, and you don't want a screen on your wrist. Choose a smartwatch if you want notifications, apps, GPS workouts and a display. Some people wear both — a ring for sleep, a watch for the day.
Check ring sizing first
Smart rings must fit precisely. Most brands sell a free sizing kit or size guide — order that before committing, as fit affects sensor accuracy.
