Smart, Sleek, and Surprisingly Insightful!
I absolutely love my Oura Ring 4! It’s lightweight, stylish, and so comfortable that I forget I’m even wearing it. The sleep tracking is incredibly accurate and has helped me improve my bedtime routine. I also appreciate the readiness and activity scores — they make it easy to understand how my body is doing day to day.The battery life is impressive, lasting several days on a single charge, and the app is very user-friendly with clear insights and tips. I also love that it looks like a simple, elegant ring rather than a bulky fitness tracker.If you’re serious about improving your health, sleep, and daily performance, the Oura Ring 4 is worth every penny. It’s like having a personal wellness coach on your finger!

Would not connect
I loved the color-perfect fit-could not get it to connect-I tried for an hour-even used their virtual assistant-same result-I kept getting-“something went wrong”. Looked up Oura’s phone number -could not find one -only that they were receiving a higher than normal volume of calls-if you don’t have enough people to serve your customers that’s poor customer service-I will not tolerate poor customer service-I won’t buy again

🔥
I had a couple of watches with trackers, but the ring is something!!!! I’m so glad I bought it.It’s super light — I barely feel it on my finger, yet it tracks everything — sleep, readiness, heart rate, body temperature, even stress levels.The insights are so much more accurate than any smartwatch I’ve tried before.I love checking my sleep score in the morning — it actually helps me understand how my body feels that day.And the design? Minimal, elegant, and goes with literally any outfit.Totally worth it if you care about your health and want something that doesn’t scream “fitness tracker.”

Sleek design
I got the ceramic one in size 8, and it fits perfectly- comfortable enough to wear 24/7, even while sleeping. The design looks sleek and elegant, and it tracks my sleep, readiness, and daily activity so accurately. The app is super intuitive and really helps me understand my body better. Totally worth it!
