    Readings are accurate as far as i can tell. More insight into overall health than Apple watch 11. One drawback is ive yet to get 8 days of charging from it. The most iver received was roughly 3.5 days. App is good and easy to understand

    I bought this for myself as a birthday present. I'm so glad I did! I wear it on my middle finger left hand. Love the rose gold. There is so much information to be gathered regarding daily life stats. Most that can be controlled. Really fascinating stuff.

    The ring fitting within the store was easy to navigate. My ring fits perfetly and the battery lasts a few days. To charge, it only takes about an hour. The OURA app is easy to navigate to get stats on your heartrate, stress, lseep patterns, excercise, and more. Highly recommend if you're interested in seeing more/ keeping track of your vitals. Note that the silver does scratch.

    The Oura Ring 4 is a game changer. It tracks my period cycle, steps, sleep quality, heart rate, and recovery with great accuracy. Comfortable to wear all day and night, and the insights really help me improve my health and workouts.

    I have been on the fence on whether to buy a smart ring or not and I’m glad I finally did. It helps immensely that, regardless of which OS your phone runs, the Oura Ring app both sync seamlessly with your phone’s native Health apps. It’s comfortable, light, durable, and the app has top-notch health insights and metrics (as a health IT specialist and informaticist myself, this is a massive positive for me). My only concern is the long term wear and tear of its coating/material but was able to grab some ring sleeves to lessen it especially when wearing it at the gym.

    Super product that provides multiple types of information on the health of the wearer. I use mine to track my steps, sleep, and heart rate. Oura tech is great, and frequently adds new types of information. Extremely easy to sync with a phone.

    I bought this for my dad and he absolutely loves it. He was using his phone before to calculate his steps but boy was he shocked by how many more steps he actually did when wearing this ring and leaving phone behind/charging/etc. It also tells him when to rest and his sleep - he just loves it. So happy as he is a hard person to buy for.
