It is built around a breakthrough sensing technology, Smart Sensing, which adapts to your finger to deliver accurate, continuous data. With 5-8 days of battery life, you'll see a complete picture of your health. It's designed with recessed sensors on the interior, making it comfortable and gentle, even on sensitive skin. Oura Ring is FSA/HSA Eligible — we can accept FSA or HSA funds for the following: Oura Ring, additional chargers, and shipping. Oura Ring 4 Ceramic Polishing Pad: Keep your Oura Ring 4 Ceramic looking like new with the Ceramic Polishing Pad, redeemable once you sync your purchase in the Oura App. Due to the hardness of the zirconia ceramic, it can take on the color of softer metals, like a dumbbell or cookware. Over time, you may notice grey marks on your Oura Ring 4 Ceramic. Rest assured, it's not damaged — it's evidence of a metal transfer and easy to remove with proper cleaning. Use caution when handling metal objects and consider removing your Oura Ring for some activities. The Oura Ring 4 Ceramic Polishing Pad is your partner in keeping your ring in top condition. IMPORTANT: Size yourself with the Oura Ring Sizing Kit before you buy — Oura Rings are not US standard sizing, and finding the right size will result in the best experience possible. With a sizing kit purchase, a credit will automatically be applied to your Oura Ring at checkout.

Review: Worth the Price! - I got a size 8 and wear it on my right pointer finger—fit is true to size and very comfortable for all-day and night wear. I’m honestly amazed at how much this ring can track, from sleep and recovery to activity and overall health insights. A huge bonus is that I was able to purchase the ring with my HSA card, and even use HSA funds for the yearly subscription as well, which made this an even better value for me. The data is detailed, easy to understand, and actually useful. If you’re looking for a sleek, comfortable wearable with powerful health tracking, I highly recommend the Oura Ring
Review: Best health tracker I’ve used for sleep and recovery - The Oura Ring has been genuinely useful for tracking my sleep, HRV, resting heart rate and recovery trends. The data feels more accurate and meaningful than what I got from wrist trackers, and since it’s tiny and comfortable I forget I’m wearing it. The app breaks everything down in a clear way and makes it easy to spot patterns (stress, hydration, workouts, etc.). Battery life is solid and lasts several days before charging. It’s a premium device for sure, but if you care about sleep and recovery data more than steps and notifications, it’s worth it.

### ⭐⭐⭐⭐⭐ A great health tracker
*by J***U on February 16, 2026*

I highly recommend getting an Oura Ring if you like keeping track of your health and I don't say it lightly. I am a Samsung girly and while I love all my Samsung stuff, I am disappointed with their Ring version. I went through 2 Samsung Rings before getting the Oura. Both Samsung rings had charging issues and stopped holding a charge. Now I have only had my Oura ring for almost a week, but I can already see that it tracks way better. The only thing I wish it could connect to is my Libre app for my Freestyle Libre 3 CGM. It does connect to Stelo by dexcom for those CGM users. I just hope that it could someday connect with Libre. Overall I am much happier.
