    I jumped from an apple watch to the ring. I feel the ring tracks and provides more information. I absolutely recommend to anyone who is on the fence for it!!

    Great ring to track your health and activity. I went the ring route because it’s easier to sleep with it on opposed to a watch or bracelet. This thing picks up a lot of health stats. Happy with my purchase.

    Only had for 1 month so far and it has been amazing. It is so cute and matches with the rest of my jewelry. My husband thought it was silly at first but now I think he wants one lol.

    Gave the Oura Ring to my wife as a gift—she loved it! It tracks everything from sleep to workouts with amazing accuracy. The app interface is super easy to use and gives her great insights to support her gym routine. It’s sleek, smart, and honestly one of the best gifts I’ve ever given her!

    Great product so far!!!It's already giving me information on my sleep and gathering info on my overall health. It takes a few weeks to gather all of my info for even more accurate info and I am so excited about making 2026 my healthiest year to date!

    I’ve been using this for about a month. It does a great job giving me an idea of how my sleep has been and if I have any breathing irregularities. My main issue is that you can’t edit an activity from a previous day. It does a good job of recognizing when you are working out but sometimes it gets the length of the workout wrong. If you don’t edit it that day then you can’t the following day. Others have complained about this as well. Hopefully a software update will fix this oversight at some point.

    One of the best things I have invested in for myself. Tracking my sleep has helped me stay on track. The ring seems very accurate and stays charged for a week. To charge from 10% to 100% battery it takes roughly 45 mins to one hour.

    A gift for my sister. She loves this ring. Wears it everyday& says how much she loves it everytime I see her. You can track so many differnt things like a fitness watch but even more in depth. Great purchase.

    Great product!! Perfect ring for the healthy conscious. Know your heart, know yourself!! If overly too handy, get those silicon ring protectors … i hate any form of scratches!

    Great piece of tech that allows me to track my sleep and stress levels. However, make sure to open the app. I recently got sick and just kind of sat around all day, and it wasnt until the evening when I checked the app, it ended up registering that I slept all day.

    Cute. Good idea in theory. However I prefer my Apple Watch. No subscriptions. Tells time. And is strapped on and does not need to be adjusted every second. The main thing I liked was it can track your sleep score, and the Apple Watch is to bulky to wear to bed, and you can log your food.

    I haven’t owned the Oura Ring for a super long time but I do love having it! I think it does an amazing job tracking my sleep and it also picked up when i had gotten sick. I prefer this over my apple watch, better battery life and tracking capabilities. Only negative is the sizing doesn’t have half sizes. I was in between a size 8 and 9. Went with 9 because the 8 was just a tad too snug. I feel an 8.5 would have fit perfectly. Very comfortable on as someone who doesn’t wear rings to bed. Love it so far!
