A great alternative to a smart-watch
I was keen to utilise technology to help with my fitness, but love mechanical watches so a smart-watch wasn't an option. Came across this and after some research I gave it a punt. Very happy customer, the ring is a doddle to set up and works a treat. Battery life is a snadge less than advertised but not enough to make me dock points. It's a shame about the subscription, as I think the ring is costly enough that it's something of a liberty to charge for ongoing use, they could lose things like the guided meditation etc and give a free option, or bake in more value-add to the app. Enough moaning though, what it does it does really well, giving me insights into my sleep patterns and broader health. I am happy I bought it and check the app at least daily months after buying.

Great item, very efficient at tracking
I love this ring, it does everything and more that you could ever want from a fitness tracker. It also works really well alongside your Apple Watch. I would highly recommend and it was sent to me within 24 hours.

So So Happy!
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.

Good product if its in the box when delivered.
My wife and I bought two rings. Mine arrived complete, but my wife's was missing the ring. So I ordered another one, thinking it was just a mistake. Her second package arrived the next day with no ring in it AGAIN.

⭐️⭐️⭐️⭐️⭐️ Game-Changer for Chronic Illness & Neurodivergent Wellness Tracking
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.

Excellent product, limited durability.
Excellent product, but oh my lord does it scratch easily! I've had mine for a few weeks now and it's is absolutely covered in scratches!

Ich suchte eine Alternative zur Sportuhr / Smartwatch und wurde fündig. Der Ring macht nicht nur optisch etwas her, sondern liefert einem auch Daten über die eigene Gesundheit. Er ist ein guter Allrounder und macht einiges sichtbar, was man im Alltag doch gerne übergeht. Mit Hilfe des Ringes achte ich nun mehr auf Bewegung und Ruhezeiten. Die Auswertungen sind zudem hochinteressant. Ich kann den Ring jedem empfehlen der auf der Suche nach einem Gerät ist, welches den Fokus auf die Beobachtung der Gesundheit legt. Sollte der Schwerpunkt eher auf dem Sport liegen, würde ich zu einer Smartwatch tendieren.

睡眠の質と日々の健康状態を把握したくて購入。 現在使い始めて5ヶ月目。 普段はPixel Watch 4をつけているけど、両方使っても全く邪魔にならない。 つけている感覚があまりないから、寝る時も気にならないのがいいところ。 事前にサイジングキットで指の太さを測ってから買ったので、フィット感はばっちり。 キットの購入代金分がしっかり割引になったのも助かった。 最初のうちはただの記録だけど、30日くらい使い続けると自分のサイクルが見えてくる。 データが蓄積されて、日々の体感とストレス測定のグラフがぴったり合うようになる。 5ヶ月間使ってみて、とくによかったのはこんなところ。 ・時計と併用しても指や手首が快適 ・30日目あたりから自分の疲れのピークがわかる ・ストレス状態の測定精度がかなり高い ・体調不良の兆候を事前に教えてくれる 一番驚いたのは体調不良の予測。 実際に体調を崩し始めたタイミングで、アプリがしっかり不調を検知していた。 ついつい無理をして、自分から休みをとれない性格の人におすすめ。 客観的なデータで「そろそろ休んだほうがいい」とストップをかけてもらえる。 今ではすっかり手放せない、健康管理のお守りになっている。
