Ring vs watch

Ring — wear 24/7 (including showers, sleep). No screen distractions. 4-7 day battery.
Watch (Apple Watch, Garmin) — has screen, calls, texts, fall detection. Daily charge.
Many people wear both — watch by day, ring by night.

What rings actually track

Sleep — quality, stages, total hours. Most accurate at this.
Heart rate — resting and trends. Heart rate variability (HRV).
Skin temperature — useful early sickness/menstrual cycle indicator.
Activity — steps, calories. Less accurate than a watch.
Stress / readiness — daily score from sleep + HRV.

Subscription gotcha

Oura locks most insights behind a $5.99/month subscription after the first month. Over 5 years, that's $360 added to the $349 ring. Samsung Galaxy Ring and Ultrahuman are no-subscription. Worth the math.

Get the sizing kit first

Order the FREE sizing kit from any ring brand before buying. Wear the sample for 24 hours. Fingers swell at night and during exercise — pick the size that fits when warm. Wrong size = the ring sits on your nightstand.
