    Once you get past the bulky feeling, the Oura Ring 4 really feels like a constant health advisor that's available at quick glance. It provides excellent feedback regarding sleep score, cardiovascular age and even has a new symptoms add-on that will try to catch sickness early! Would highly recommend!

    I have Apple Ultra Watch 3. The ring and the watch results don’t match. I am not sure which one is correct. Thus, I use the average readings from both to see my results. Also, I don’t have to pay subscription for my Apple Watch. Oura requires subscription.
