Leak: Oura Ring 5 launches on Thursday as world's smallest smart ring

After a leak recently revealed many details about the Oura Ring 5, Winfuture confirms this leak and provides a range of new information and images. The Oura Ring 5 is to be officially unveiled on Thursday, May 28, with deliveries expected to begin on June 4. The cheapest version of the ring will cost €429, which is €30 more than the list price of the Oura Ring 4 ($349 on Amazon).
Depending on the color, the ring will cost up to €529 and will be available in silver, black, gold or rose gold with a polished finish, or in silver or black with a matte finish. To use most of the features, a subscription must also be taken out, which costs €5.99 per month. The leaked marketing material advertises the Oura Ring 5 as the "world's smallest smart ring" – the more compact body is primarily intended to make it more comfortable to wear.
The battery life increases to one week. The ring is waterproof to a depth of 100 meters. If you take out a subscription, the Oura Ring 5 gives you access to over 50 health metrics, including sleep and workout tracking, a pedometer, round-the-clock heart rate monitoring, stress and cycle tracking and a "symptom radar" that is supposed to be able to detect the first signs of illness at an early stage.
Oura Ring 5 apparently comes with a dock for charging and a USB-C cable, but if you want a charging case for charging while traveling, you will have to buy this separately. Judging by the pictures, the built-in heart rate, SpO2 and skin temperature sensors are larger and could therefore provide more precise data, but Oura is unlikely to be using completely new sensors.
