    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.

    Great product. It’s very helpful and motivating to fix your sleep schedule. Battery lasts forever. If you don’t like smart watches this is the product for you. Try it you won’t be disappointed. Make sure you get the right size! Only con is the monthly app fee it’s like $6 but worth it to me.

    This is my newest oura ring. Followed them since I heard they were coming out. Bought a second gen one and had for 6 months. Wouldn't charge. Oura sent me a brand new ring and it lasted for year and half. Started losing charge more quickly so upgraded to the newest. I have learned so much about how my body works with sleep habits and my health and how my energy levels work from sleep and how my body reacts to stress and how to offset it. Love this ring and the monthly subscription is worth it to me. They are always adding new things to the app and still learning about my body, even after years of using the ring!
