    I love using this for cycle tracking! I dont know how accurate the step count is but it seems pretty close to my apple watch. I also use it to record workouts so i can see my HR zones but i still use my apple watch as well. Definitely get the ring sizer to know which size to get if ordring online!

    I love my Oura ring. Very happy with my purchase! The ONLY issue is I wish is was not as bulky BUT I realize that there is a lot happening inside that little band, so it is amazing it is as small as it is.

    I wasn’t sure if I was going to like it. I tried it and for the 1st few days I was skeptical. After a week I noticed I did improve on my sleep and move habits. It’s also nice because it’s something different the wrist fitness trackers it’s both useful and fashionable.
