    Great product for health information on a daily basis. I can keep up with total steps,which is more accurate than my Apple Watch. Get sleep data, plus activity level, alone with information to let me know about any temp changes to alert me about potential infection.

    I got this ring to track my period and to use as birth control. It is still getting used to my body so i can’t yet if that worked, but i do like being able to see my sleep patterns, it also caught that i was sick. It measured my temp as well and that pretty cool.

    This is where the Oura Ring shines. It tracks a wide range of health metrics — including detailed sleep stages, readiness scores, heart rate, stress, and activity — all collected automatically while you wear it. The sleep tracking is especially detailed and insightful, often more nuanced than what you get from regular smart watches.

    I think it does what it says it does. I've only had one week. I like it- I struggle wearing a ring all the time but I'm getting used to it. It's very comfortable. I switch between my forefinger and middle finger. I'm still getting used to the app. I do think the steps are overestimated.
