Q: How does the Oura Ring track sleep, activity, and stress levels?

A: The Oura Ring uses advanced sensors to monitor your sleep, activity levels, temperature, stress, and heart rate.

Q: What is the maximum depth of water resistance for the Oura Ring?

A: The Oura Ring Gen3 has a maximum depth of water resistance of 328 feet.

Q: Can the Oura Ring be used to track blood oxygen levels?

A: The Oura Ring Gen3 tracks your blood oxygen levels.

Q: What kind of battery does the Oura Ring use?

A: The Oura Ring uses a lithium-ion battery.

Q: Does this ring work without paying for a monthly subscription? I saw these on display at my local Best Buy and I want to buy as my wedding ring, but would not pay $6 a month in perpetuity.

A: Yes, 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.

Q: Just curious about the negative impact this could have on my health, with the battery emitting radiation. My girlfriend had an Iwatch that burned her wrist,that kept me from getting one but I want to get something to track my heart/sleep

A: The 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.

Q: I'd like to know what is the return policy? I don't want to buy it unless I know exactly what the limitations might be. What if it doesn't work properly? What if its not really the vet size for me since they don't have half sizes?

A: You 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.

Q: All the pictures I’ve seen have the ring on index finger, is this recommended over any other finger?

A: The 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).
