    I was a bit sceptical at first but absolutely love the Oura Ring. I don't like wearing my apple watch around the clock but Oura ring is simple comfortable to wear. You must suscribe to the app but the daily insights are amazing when it comes to your health and daily activities. It is not just limited to working out but also sleep quality, stress, temperature, etc. Highly recommend.

    I loved my Oura ring. I have a hard time sleeping and knowing I got X amount of hours, specifically under 7, it forces me to try and sleep more when my score is low. It helped me prioritize that and definitely just overall rest when it detected stress on my body. Very insightful.
