The Oura ring is the BEST!!
I absolutely LOVE my Oura ring. It has exceeded all of my expectations. As someone who previously wore a fitness watch, I say that the ring is much more comfortable, cute, and convenient. I wear it 24/7, including overnight for sleep tracking and rarely notice it there. This is coming from someone who used to take off all my jewelry before going to bed. The only time I take it off is when I am showering and that is when I charge it! The ring is able to go in water though which makes it super convenient for swimming and life with kids.The battery life is phenomenal, meaning I don’t have to constantly worry about charging it. It’s been very accurate for monitoring my cycle as well. You can double it with natural cycles as a very accurate form of natural birth control/cycle monitoring. It’s also surprisingly stylish and sleek. If you want an overall fitness/health tracker, this is the one for you!

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!

Amazing
The Oura Ring 4 really surprised me. It’s light, discreet, and so comfortable that I forget I’m wearing it. The sleep, activity, and heart rate tracking is very accurate, and the app explains everything in a clear, easy-to-understand way that actually helps in my daily routine.The battery lasts a long time, charges quickly, and the overall quality of the ring is excellent. If you want to track your health and wellness without wearing a watch all the time, this ring is perfect.I’m loving it and highly recommend it!

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.

Ich nutze den Oura Ring 4 nun seit einigen Wochen und bin rundum zufrieden. Die Verarbeitung ist hochwertig, der Tragekomfort hervorragend – selbst nachts stört der Ring überhaupt nicht. Die Messwerte zu Schlaf, Aktivität und Erholung sind erstaunlich präzise und helfen mir, meinen Alltag bewusster zu gestalten. Besonders die neuen Funktionen zur Hauttemperatur und Stressanalyse finde ich sehr gelungen. Wer eine unauffällige, aber leistungsstarke Alternative zu einer Smartwatch sucht, ist hier genau richtig.

事前にサイズキットを購入して１，２日候補となる指でつけて生活することはマストです。Ouraリングそのものはデータが好きな人間にとって最高のツールです。結構厚みもありますが、日常生活で邪魔に感じることはほとんどなく日常の一部になっています。

I discovered the Oura Ring 4 through the Clue period tracking app, and it’s been a total game-changer. I live with Chronic Fatigue Syndrome, Fibromyalgia, and AuDHD, and I was looking for something that could help me track sleep, stress, body temperature, and recovery. Oura delivers on all fronts—and then some.What I love most is the accuracy and depth of insight. It doesn’t just give you only the minimal data, like Deep, Light and REM sleep, but also things like how long it takes you to get to sleep (latency) and how restless you are —it then translates this into genuinely helpful feedback, like sleep and recovery scores, body temperature trends, and guided breathing for stress.The daily readiness score helps me pace myself, which is essential when managing fatigue and sensory overwhelm. The breathing and mindfulness sessions have been a great tool during flare-ups or overstimulation.A few things to note:There is a monthly app subscription, but it’s reasonably priced for what you get. I also got a month free when I signed up.The app is intuitive and easy to navigate, though some people might need a bit of time to explore all its features—there are a lot, and they’re all useful.It takes about 90 days for Oura to fully calibrate and understand your individual baseline, so the insights get better over time.Buying the sizing kit first is a MUST—you’ll want a good fit for accuracy and comfort.Tagging activities and meals is super simple (if you remember to do it).The Rest Mode is a thoughtful feature for days when you’re sick, in pain, or recovering, though I do wish stress tracking stayed active during this mode.Battery life is solid, syncing is quick, and the ring itself is lightweight and comfortable—even with sensory sensitivities. It also integrates beautifully with Clue for cycle tracking, which adds another layer of helpful data for me.If you’re managing chronic illness, neurodivergence, or just want a deeper, more holistic view of your health, I can’t recommend the Oura Ring 4 enough. It’s not just about fitness—it’s about understanding your body, honoring your limits, and supporting your wellbeing.

後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。２４時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない
