    I purchased the Oura - Ring 4 - Smart Ring for my wife as an adjunct tool to monitor her cardiac rhythm. She wore a Holter Monitor prescribed by her physician for 2 weeks, and I also purchased an Apple Watch Ultra for her to monitor her cardiac rhythm. The Ring 4 is the easiest to wear, charge, and monitor via its app. As her husband physician it was the simplest device to track for her. Now that she no longer needs it, I wear the ring on a different finger, and I enjoy the physiologic insights it gives me about my body.

    Best.gift.ever. Battery lasts a long time. After four days it’s still at 50%. I’m tracking my sleep and trying to improve. Now that I have this ring, I understand my sleep patterns and have suggestions on how to improve. Looking forward to more health data in the future.
