    It is really good product. If you are wearing smart watch then it is dependent on the smart watch for data. I wish ring itself comes up with the activities. So far I love the ring and its functionality. I am hoping to get rid of the smart watch so I can wear real wrist watches.

    I’m a gen3 owner and I switched to gen4. Way more comfortable, but the design and build quality seem lacking this generation.

    Very impressed with the metrics this collects. I have this alongside my Apple Watch and I feel this has helped me track my Menstrual cycle in better predictions and gives me great insight about my rest and recovery after sleep. I only subtracted 1 star because it requires a mandatory monthly subscription but otherwise fantastic tool for health insights.

    I decided on the Oura Ring over a smart watch and I am happy with its simplicity. So many options available within the app itself to help monitor your daily health, sleep, and activity.

    Love the ring bought it for my daughter. She swears buys it. Helps her monitor her sleeping habits and she can tell when she’s got a cold coming on. Her temperature actually rose when she got sick on her ring so it works.
