You'll need to subscribe the app (pay regularly), to have full function support.
Size is accurate. However it's thicker than I imagined. Battery life is good, recharge ~5 days.

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!

Awesome product. Perfection in everything. Does not throw numbers and data and interpretations at you immediately. Comfortable to wear. Just make sure you have tried the sizing kit before hand for atleast 4 to 6 hours if not 24 hours. I am getting a battery life of 5 days plus.

I have been using it for the past 4 months and its very accurate, is not bulky and the battery lasts around 5 days. The key metrics are very useful and it allows me to see how alcohol, a bad sleep or extra caffeine can affect my body.
