    • Must Have Health Tracker
Color: Gold Size: 8
Review Image by Nikita Nikita
I’ve been using the Oura Ring for about a week now, and it’s already been a game-changer in understanding my health and daily habits. Here’s what stood out to me: Design and Comfort The sleek design makes it look like a regular ring, and it’s surprisingly lightweight. I often forget I’m wearing it, even while sleeping or working out. It’s also water-resistant, so I don’t have to take it off for washing hands or showering. Features and Insights The Oura Ring tracks sleep, activity, and readiness with remarkable accuracy. It even detects when I’ve taken a nap! The sleep insights are detailed, breaking down REM, deep, and light sleep stages. It’s helped me make small changes, like setting a consistent bedtime, that have improved my overall rest. The activity tracking motivates me to stay active without pushing too hard. I love how it adapts to my energy levels, giving personalized recommendations for recovery or exercise. Battery Life and App The battery lasts about 8 days, which is impressive compared to my Apple Watch. The companion app is intuitive, with easy-to-read metrics and actionable tips. Syncing with my phone has been seamless. What Could Be Better The price may feel steep, but considering the wealth of data it provides, I believe it’s worth it. Also, sizing can be tricky, so make sure to use the sizing kit they offer. The ring is HSA/FSA approved so it made the purchase more affordable since I had the money already set aside. Final Thoughts If you’re looking for a discreet, powerful health tracker, the Oura Ring is an excellent investment. It’s perfect for anyone who wants to optimize their sleep, monitor activity, and improve overall wellness without wearing a bulky device. 5/5 stars! Highly recommend. ... show more

    • Best Purchase Ever

Review Image by Azia Mortensen Azia Mortensen
I’ve had watches, Fitbit’s, you name it but this is the best thing I’ve come across so far. The amount of detail and insight I receive into my health is unmatched. I finally feel competitive with myself and want to better my habits based on how my numbers fluctuate. I love that this also gives insight into how my sleep habits are and when to best navigate bedtime based on my habits. I love that it changes and adapts to me and isn’t a one size fits all health approach. Worth every penny for the functionality as well as the sleek design. I initially purchased the 3 and quickly exchanged it for the 4 to rid of the bumps on the inside and it’s so comfortable I forgot I’m wearing it. The charging is so fast, the silver is nice and while has a couple scratches, stays very clean and shiny. ... show more

    • Give it time to feel normal and store data.
Color: Silver Size: 12
When I first put on the ring, I didn’t like it. It felt bulky and I was constantly changing fingers. Finally, after more than a week, I settled on the middle finger of my non-dominant hand. I sleep with it on, but I’m not sure how accurately it tracks my REM versus non-REM. I also JUST found the oxygen saturation metrics under the sleep screen. This ring does a LOT more than I initially thought. My ring is the polished silver and I am not having any issues with scratches or markings. The battery life seems good. I charge it about every 5 days or so. I like the sleep and activity reminders. The app is good and easy to use. It takes several days to track and store usable data for trends. Pairing the ring with the app was simple. Overall I’m happy. ... show more

    • Comfortable, Classy, & Helpful

Review Image by Dylan Martin Dylan Martin
I love this ring. I tried the Whoop Band for a bit and found it not comfortable enough for 24/7 wearing. The Oura Ring, though? Honestly, by the end of the first day, I got used to it. If you've ever worn a cheap, simple ring, this is about equally as thick. The titanium is nice, though. Feels very sturdy and I've already gotten compliments about the way the light shines against it. Now let's talk about the smartness. 2 days ago, it warned me that I might be getting sick. Today, I woke up with a cold and Oura was like, hey! Seems like you're sick. You should probably turn on rest mode! Now that's some wizardry. The Oura Advisor (currently under Oura Labs) is also freaky helpful. I even asked it if it was weird that this AI felt like a second therapist for me and it gave a thoughtful, insightful answer! I was pretty blown away. Especially as it supported my use of other help apps, as compared to simply telling me to do everything through Oura. Selfless, like a proper advisor should be. It also charged super fast. I've only taken it off for showers and that has been more than enough to keep it consistently above 50%. The other thing I liked over the Whoop is that the app is very simple and hands off. The whoop was very hands on and complicated. It felt like work to under how my body was doing, whereas Oura just gives it to you straight and doesn't ask much of you, which is much prefer. It's only been a few weeks, but I'm a big fan so far. ... show more
