A: It says the State of California because it is the only state out of the 50 states that requires to let consumers know there are cancer causing materials or chemicals in the product. It doesn’t make it less important. It should be legal in all states to disclose this important information. Just because many products say this nowadays doesn’t make it less important. It just means that most of the products that we buy today have cancer, causing chemicals and all of that adds up. This ring is a fad with cool features, but is it worth being exposed on a daily basis?

A: Everything that comes from California has this warning on it.

A: The State of California places this label on just about everything you purchase.

A: Hi Flirtygirl1, thanks for reaching out about Oura Ring 4 Yes, the Oura Ring 4 can track blood oxygen levels (SpO2) If you have any additional questions, we welcome you to contact MyTGTtech at 833-848-8324 every day, between 7am-11pm CST.

A: Not exactly if you are looking for immediate Sp02 levels like an oximeter. I just checked my app and it shows that my oxygen is measured during my sleep only: “Average blood oxygen and breathing regularity are analyzed by looking at your blood oxygen levels with Blood Oxygen Sensing. Blood oxygen measurements are located in the Sleep tab and become available after your next sleep period of more than 3 hours.” I went to the Sleep tab and it shows an Average Oxygen Saturation %, ex. 97%. If you’re looking for direct Sp02 readings, I would rely on an oximeter and not the Oura ring.

A: I got rid of my Apple Watch and switched to Oura (Gen 3) and I’ve had it for 3 years now. Never looked back. It gives me so much info about my heart, how I’m sleeping, and my period cycle which is way more than the Health app through Apple and the Fitbit I tried. I have compared the Apple vs Oura data and Oura has been 100% more reliable. Very helpful since I have dysautonomia and autoimmune diseases that I need to have data readily available. Oura also syncs up with Apple health but provides more info. Anyways, I’m saying the $5.99/mo is worth it. You can also have the free version with less info provided to you.

A: YES if you're diving "recreationally". Like off a diving board, a cliff, or just into the ocean or a pool. Any diving that won't submerge you deeper than 330 feet is fine. Scuba diving is a NO.
