Oura helps you understand how your cycle affects your body, so you can make better, informed decisions about your holistic health. Track the changes in your body throughout your cycle and predict your period up to 30 days in advance.
- Stress: Oura will help you identify signs of stress and understand how well your body handles it. You'll know when you need to incorporate more self-care practices and how to recover from long term stressors.

A: You get the membership for the first month for free just for buying the ring. If you choose not to renew you only are able to access sleep, readiness, and activity scores. You won’t get access to the symptom radar, stress insights or other features. I’m not even sure if without the membership if you can access the details of your sleep or it’s just a score. Hope this helps!
Q: Does the black get scuffed or scratched easily?
A: I have the 3 in black have not had it a year and it is all scratched up. It looks horrible. I hope the 4 is made better
Q: Do you know if a charger is included with the ring, or do you need to purchase it separately?
A: Charger was included with the ring.
Q: Can you get a trade in for a new Oura ring?
A: I went in today with the same ring and they offered me $22, Hope that helps!
Q: What finger do you need to wear the ring on.
A: The website says that it can be worn on any finger but for the most accurate data, wear it on your pointer, middle, or ring finger of either hand.
A: I was able to purchase at a Best Buy using my HSA debit card.
A: I read one review - can't remember where now, maybe thewirecutter.com - that said it hurt the reviewer's hand to wear while lifting, but was recommended otherwise. Regarding scratch protection, there are a ton of silicon covers available from third parties.
A: I got the protection because it covers everything except fire and theft I believe. Yeah the coverage was expensive but the ring itself was way way more. If the battery quits on me for whatever reason I would want a replacement

Amazing Insight into My Health and Sleep
I’ve been using the Oura Ring for a few months now, and I’m genuinely impressed. It’s sleek, comfortable, and so easy to wear that I often forget I have it on. The data it provides about sleep, readiness, and activity has really helped me understand my body better and make small changes that have a big impact. The sleep tracking is particularly accurate — it shows not just how long I sleep, but how well. I love being able to see my sleep stages, heart rate variability, and recovery score every morning. The app is intuitive and gives practical suggestions instead of just numbers. Battery life is excellent (about a week per charge), and the ring itself still looks brand new. It’s also nice that it can track temperature and even detect early signs of stress or illness. Overall, it’s one of the best wellness investments I’ve made. Highly recommend it to anyone serious about improving their sleep and overall health.

Amazing!!
I got the black oura ring and I love it! So far so great! Has shown me how certain events are stressing me out to high levels and others are relaxing me. Still a little too early to see cycle results however I'm hopeful. So glad I made this investment I forget that it's even on and I'm able to see how well I've been sleeping and what I need to improve for sleep! Glad I went with the 8 because even with some swelling from running around or sleeping it's big but not too snug and a 9 would have been too loose on my middle finger and too tight on my index finger. Battery life is great honestly has lasted me a long time I love that I don't have to charge it everyday!
