Frequently Asked Questions
Is the subscription required?
Without the subscription, you get basic metrics (readiness, sleep, and activity scores). With it (EUR 5.99/month), you get detailed insights, trends, and personalized recommendations.
How do I find my ring size?
Oura sends a free sizing kit before purchase. Wear the test rings for 24 hours — your finger size can change throughout the day.
Can it replace a smartwatch?
No. It doesn't display notifications, can't make calls, or run apps. It's a focused health and sleep tracker. Many people wear both.
