    Really helps with keeping my health on track. I also have the Apple Watch, but I find the Ring 4 information to be more accurate and more realistic.

    Got this ring for my wife’s Mother’s Day gift. She loves it. Had actually helped her with her daily tracking of stats and how to change some habits for better focus and sleep regimens. She absolutely loves it.

    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!

    Love it! I’m still learning what all it does. Keeps up with my sleep which is why I bought it. Helps me keep up with my sleep apnea, my steps, my stress levels and a whole lot more. Even tells me when I’m sick before I know it. Very happy with my ring.
