    Excellent wellness tracker. The more you wear it the more insides it gives you about your sleep patterns and how this affects your averall health. It helps you calibrate on your own your lowest heart rate so you can have over all cardiovascular health and a strong response to stress.

    If you want to monitor health, this ring helps you do so! It’s great quality and looks beautiful on my husbands ring finger. I hope there will eventually be a way to monitor blood pressure. But, I knew that wasn’t an option at this time when I made the purchase. There is a $5.99 subscription service for the ring. I also knew that when making the purchase. I am pleased with this purchase.

    i loveeeeee my oura ring! it’s so easy to set up, the instructions for how to best use it/charge it/how it tracks are so easy to follow. and if you have any questions, the app itself makes it so easy to find the information you’re looking for.
