The Oura Ring Gen3 and the Oura Membership ($5.99/mo plus tax) work hand-in-hand to help you feel your best. Monitor your sleep, activity levels, temperature, stress, heart rate, and more with the most trusted Smart Ring. Whether you’re focusing on your fitness or want to improve your sleep, Oura helps you take control of your health — in style.
Oura Membership
First month of membership is on us with your purchase, $5.99/mo plus tax afterwards. Offer available to new members only. Membership is tied to your account accessible via the Oura App, not your physical ring.
Size Before You Buy
Order an Oura Ring Gen3 Sizing Kit to find your optimal size, then return to BestBuy.con to buy your Oura Ring Gen3.
Sleep Score
Your Sleep Score answers, "how well did you sleep last night?", based on data points including: total sleep, how much time you spent in each sleep stage, HRV, and more.
Readiness Score
Readiness is a holistic picture of your health — taking into account your recent activity, sleep patterns, and key biometric signals.
Activity Score
Your Activity Score is comprised of three core pillars — inactivity, activity level, and recovery.
Stress
Oura will help you identify signs of stress and 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.
Resilience
Stress Resilience visualizes how well your body withstands stress over time and helps you build resilience to get through life’s challenges. A healthy amount of stress, sleep, and recovery keeps you prepared for whatever comes your way.

You may be eligible for reimbursement on your Oura Ring purchase. You can submit your Best Buy confirmation email to your FSA or HSA provider as proof of purchase.

Learn how your body responds to your daily habits and choices by following your heart rate from morning to night.
Automatic Activity Detection
You no longer need to manually start an activity. Whether you're running a marathon or running an errand, Oura automatically detects over 30 activities for you and delivers insights afterwards.
Activity Levels
Step count, calories burned, inactive times, training frequency, training volume, and more.
Activity Goals
Personalize goal types and baseline goal numbers in the Oura App. Activity Goals in Oura are still dynamic, which means that activity goals are increased on high readiness days and decreased on low readiness days.

By detecting your blood oxygen levels at night, Oura can tell if you're experiencing any breathing disturbances.

A: AnswerThe Oura Ring Gen3 tracks your blood oxygen levels.This question and answer was generated by AI based on customer and product data.Q: QuestionWhat kind of battery does the Oura Ring use?(1 answer)
A: AnswerThe Oura Ring uses a lithium-ion battery.This question and answer was generated by AI based on customer and product data.- A: AnswerYes, the Ring works, but the information without the subscription is nearly useless! Without the subscription, Oura withholds ALL basic source information provided by the Ring. Instead, Oura only displays "Activity Goal", "Readiness", and "Sleep" scores. These scores are nearly useless because they are based upon information provided by the Ring that you will no longer be able to see. For example, the "Activity Goal" score is based upon your individual goal for steps - but without the subscription, you will no longer be able to see, set, or update this goal! The "Sleep" score will be based up go-to-bed and wake-up times that may not be correct, but without the subscription, you will have no long have the ability to see that the information is wrong or be able to correct it. Therefore, if you want to continue to get the promised value from your Ring, you will HAVE to continue the subscription! This will bring a total three-year cost of the ring up to about $500!! Buyer beware! I bought my ring directly from Oura with a 6-month subscription included. Now that my subscription has run out, I am very disappointed to find out that there is almost no value to the ring without the subscription. I would not recommend the Ring unless you plan to pay for the subscription and include the subscription cost in your planned cost of the Ring.

- A: AnswerYou may return any fully functional and undamaged Oura product for any reason within 14 days for a full refund or exchange. Shipping and handling charges are not refundable. For exchanges, original orders are limited to one ring size, color, or model change within the same price range. If you have any concerns with your ring, you can also submit support requests through the Oura App and Oura website.
Answered by Oura Ring
- A: AnswerThe Oura Ring emits minimal electric and magnetic fields (EMFs) and allows users to enable Airplane Mode to limit contact even further. The limit for Specific Absorption Rate (SAR) for a device such as the Oura Ring is 2.0 W/kg for the head and body. The Oura Ring SAR level is 0.0003 W/kg. Additionally, Bluetooth is only active on the Oura Ring for short periods, well below 1% of the day. Data is transmitted more continuously when the ring syncs with the app and during firmware updates.
Answered by Oura Ring
- A: AnswerThe Oura Ring works on all fingers and can be worn on either hand. For optimal performance and accuracy, we recommend wearing your Oura Ring on your index finger. If you prefer another finger, the middle or ring fingers are the next best, but try to avoid fingers with large knuckles (where the base of your finger is narrower than the knuckle).

"Reliable Precision in a Sleek Package”
The Oura ring I purchased impressed me with its overall quality and reliability. The build is solid, featuring durable materials that give it a premium feel without being too heavy. It has a sleek, unobtrusive design that blends well with both casual and formal wear. In terms of reliability, the ring consistently delivered on its promises. The battery life was sufficient, lasting several days on a single charge, and it paired seamlessly with my smartphone, maintaining a stable connection. As for accuracy, the smart ring performed exceptionally well. It provided precise health metrics like heart rate, sleep patterns, and activity tracking, comparable to more traditional fitness wearables. The sensors appeared to be finely tuned, with data aligning closely to what I’ve seen from other trusted devices. Overall, this smart ring is a dependable and high-quality option for anyone looking to add smart features to their everyday jewelry.

Good for sleep/stress, not activity tracking
I got the Oura ring for 3 reasons: 1) Sleep analysis since I've always had a terrible time falling asleep and getting enough deep sleep. 2) I was also curious about the stress insights since I'm on the anxious side which surely contributes to my sleep issues and lack of energy. 3) I wanted a low profile wearable device that measures basal body temperature so I could track my ovulation trends. Long story short, it did all of these things well. Now onto the cons: 1) I didn't know your fingers swell when you sleep so I woke up with the circulation cut off my finger. I now move the ring to a smaller finger before bed. I wish the ring was an open design to to account for how much your fingers change size over the course of the day/night. 2) It is really bad at activity tracking. You cannot "start" / record a workout like on an Apple Watch or Whoop. It will "detect" a workout and ask you to confirm afterward (ex. "Did you do a 15 min walk?") but it rarely detects the right amount of time, if at all. 3) It is difficult to grip weights or dumbells tightly because of the ring's bulkiness. 4) The ring is useless without the $5.99 monthly subscription to access your data. So factor the cost of the subscription into this purchase. Overall, it gives me a lot of valuable insights and it excels in sleep and stress data.
