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.

โญ๏ธโญ๏ธโญ๏ธโญ๏ธโญ๏ธ Game-Changer for Chronic Illness & Neurodivergent Wellness Tracking
I discovered the Oura Ring 4 through the Clue period tracking app, and itโs 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 frontsโand then some. What I love most is the accuracy and depth of insight. It doesnโt 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 โit 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 itโs 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 featuresโthere are a lot, and theyโre 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 MUSTโyouโll 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 youโre 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 comfortableโeven 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 canโt recommend the Oura Ring 4 enough. Itโs not just about fitnessโitโs 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 fรผndig. Der Ring macht nicht nur optisch etwas her, sondern liefert einem auch Daten รผber die eigene Gesundheit. Er ist ein guter Allrounder und macht einiges sichtbar, was man im Alltag doch gerne รผbergeht. 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 Gerรคt ist, welches den Fokus auf die Beobachtung der Gesundheit legt. Sollte der Schwerpunkt eher auf dem Sport liegen, wรผrde ich zu einer Smartwatch tendieren.

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!
