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.
Review: I love it! - I don't like wearing wrist watches, so having a smart ring is PERFECT for me! I love how durable it is, it's easy to clean, and the app that comes with it is GREAT! The tracking on this thing is flawless and it uses light sensors to track my vitals, so it doesn't even feel like a smart device, just a regular ring! It also charges very quickly, so if I'm using the bathroom or taking a shower at home, I just pop it on the charger for 10-15 minutes and it's good for a few days! I only do it daily just to establish a good routine, and I have forgotten before and let the battery get low, but still haven't had the power die on me yet! I can see it being an issue for lifting weights since it's coated in stainless still and a little bulky, but otherwise very comfortable for other forms of exercise! I can also see it being a problem because of the red and green light sensors at night, it might be disruptive to light sleepers in a dark room, but I just keep my hands under my blankets or pillows, and I sleep just fine! It doesn't light up all the time, just periodically throughout the night. If the tiny lights at night might bother you, you can probably put a thick sock or a glove over your hand at night to block the light. I'm personally not inconvenienced by it at night, and I like that I can't feel anything when it checks my vitals (heart rate, blood oxygen, temperature, just to name a few). I wound up subscribing to the app anually because I really liked how easy it was to set up and how thorough its analysis was for my overall health. UPDATE: Recently I noticed the ring was draining too fast between charges and I actually needed to charge it everyday! I reached out to customer service via the app, they asked a few questions, and shipped me another one immediately! It was refurbished, not brand new, but it works like new and I would never have known the difference if they didn't tell me! I keep the old one as a backup just in case since they said I don't need to send it back. I basically haven't stopped wearing the Oura ring since I put it on, and I've used it on long walks, swimming (fully submerged in water), and for general daily activities and it works great! I wash it with soap and water when I wash my hands and take it off to give it an.wxtra good wipe down before popping it on the charger or putting it back on!

### ⭐⭐⭐⭐⭐ Worth the Price!
*by R***S on January 18, 2026*

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
