⭐⭐⭐⭐⭐ 5/5 – Game-changer for my fitness and wellbeing
I work out 5 days a week, and my Oura Ring Gen 4 has been an absolute game-changer for my routine and recovery. The sleep tracking alone has helped me understand how my body actually recovers, not just how hard I train. Seeing my sleep quality, readiness, and recovery metrics every morning has completely changed how I plan my workouts. What really stands out is how seamlessly it tracks my overall wellbeing—from sleep stages and recovery to daily readiness and trends over time. It’s helped me dial in better habits, know when to push hard, and when to prioritize rest. The insights feel meaningful and actionable, not just data for data’s sake. On top of that, it’s comfortable, unobtrusive, and easy to wear 24/7. The battery life is great, it runs easily for about 6-7 days with one full charge, plus it charges pretty quickly. If you’re serious about training, recovery, and long-term health, this ring is 100% worth it. I honestly can’t imagine my routine without it now. 💪

Amazing product & customer support service!!!!
I absolutely love this ring and all it offers. I’ve recommended it to everyone who has asked about it in the 11 months I’ve been wearing it (24/7). I know at least one person who has purchased one based off of my recommendation. Lately, within just the last few weeks, I’ve noticed the battery life has decreased sufficiently. Going from 5-6 days between charges to 2-3 days. Then the last week, I’ve begun having connectivity issues. While frustrating, I love this ring. So much so that I was seriously considering buying another one. But that $400.00 price tag is steep. Today I decided to submit a question for help through the app. Within 5 minutes tops, the virtual assistant determined I was indeed having issues, confirmed the ring I have is in stock and informed me that a replacement would be shipped with arrival time at 1-2 weeks. I am just under the year (purchased 4/8/2025 and today is 3/4/2026) but that was unexpected and honestly, amazing!!! I am so impressed. Enough so, I came to Amazon to write a review (which I never do). I will continue to recommend this product to anyone and everyone who asks!!!

Amazing data collection… but a very steep price and short life.
Note: This is a long term review, after owning the ring for 10 months. It disappoints me to have to give this a 1 star review, because when the ring works, it works. It’s very convenient, accurate, un-intrusive to wear, and gives you a ton of valuable data, especially related to your cardiovascular system. But, out of the blue about 10 months into my ownership, battery life has cratered, and even when it doesn’t run fully discharged, it has randomly started disconnecting, meaning it’s not harvesting the data that I expect and want it to, and even worse, without full days of data, it won’t build any trends, meaning the limited data it does collect is useless. Reading online it seems I am not the only person experiencing this disappointment. Oura’s customer service is non existent. I have yet to figure out how to get in contact with a human there. All their customer service is routed through “Finn” their AI assistant. After trying everything that “Finn” has recommended numerous times, and getting nowhere, it would be an understatement to say I am frustrated. One of “Finn’s” suggestions is to fully wipe the ring and app from your phone and reinstall it, and if that doesn’t work, the implication from the system is that it will then elevate it to a customer service rep. The issue with that is when you do that, a hard reset and reinstall, the record with “Finn” also seems to go with it, so the system will never engage a human, it comes across almost like it’s intentional firewall in their service. I am coming up on my 1 year membership renewal. I am at the point where I need to decide if I need to make the $72 annual investment again. I would gladly spend that again, but I’m not really looking at a $72 investment. Given my current ring performance, this means buying another ring. Between the membership and a new ring, with taxes, shipping, etc, etc, etc that’s a near $500 investment; and since it only made it 10 months, that really means it’s effectively closer to $600 a year. Battery powered wearables have a limited life; I went into this understanding that, but, I don’t think that after less than a year of usage, going from ~5 days of battery life and collecting non-stop data to less than 24 hours of life with random crashes is in any way acceptable. Apple or Garmin or Google would have mass recalls or replacements on their hands if their wearables behaved like this. Good health is priceless. The ring helped me tremendously in my fitness journey. I have lost over 65 lbs with its help. At this point, however, given I have hit and am maintaining my weight goal, and from my current experience as well as based on what I read from others online, I refuse to spend any more money with Oura, simply because of their poor customer service and poor product life. My final thoughts: the ring makes your fitness journey significantly easier. Data is king when you’re committed to self improvement. For that, I give it 5 stars; but if you buy one, understand that it most likely will not make it to a year without some sort of collection or battery issue. You have to decide for yourself if $500 for 10-ish months of data is a fair price to pay.

Amazing health tracker
Getting an Oura Ring has honestly been one of the most helpful tools in my health journey. Instead of going into appointments trying to explain symptoms from memory, I now have clear, daily data showing my heart rate trends, sleep disruptions, and recovery patterns. Because of the consistent tracking, I was able to show my doctor objective patterns rather than just saying “I feel off” or “my heart feels different.” The data helped validate what I was experiencing, which ultimately contributed to receiving an actual diagnosis instead of being dismissed. That alone made it worth it. It’s especially helpful seeing nighttime heart rate, HRV, and how my body responds on days when my symptoms flare. Having that timeline has made conversations with my care team more productive and taken a lot of the guesswork out of my treatment discussions. More than anything, it’s given me a sense of control during a really overwhelming health season. Instead of feeling in the dark, I can advocate for myself with real information — and that has helped guide a more informed, personalized plan toward my treatment and recovery.

Information Rich Health Monitoring.
My joints are larger than my fingers, causing sensors to disconnect at times. If sleep is poor and short, it refuses to report until sufficient time has passed. Naps do not get the same level of sleep mapping. Temperature readings vary by both sensor contact and position (under/over covers). Still, an absolutely amazing device. Continuous Improvment between versions.

I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it. First, the fit and metal colour are great, I couldn't be happier, the quality and durability is insane, i do everything with it, I rarely take it off. The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility. Now, you need to give it time to gather data about you, of course... it will not happen overnight which is quite right, but the intel you get afterwards is great. Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it. I highly recommend it if you are curious and want to be nudge in the right direction for better health.

10/10! I love this ring! I have been wearing this ring for months now! The app is incredibly user friendly and very easy to navigate. It’s approx $9 a month for the service but the amount of data collected is worth it in my opinion. My ring has scratched a bit but it’s to be expected with an almost mirror finish on the polished silver one. BE SURE TO BUY THE SIZING KIT! Wear the sizing rings for at least 24 hours to get a feel for the right size. I originally believed i would be a size 9 as i wanted to wear it on my middle finger. After 24 hours I could tell the 9 would be much too tight with regular movements and swelling of hands. the 10 fits great and it looks so pretty with a stacking ring on top of it!
