Oura has presented its Smart Ring Generation 3 with new sensors and functions. Most notable is the continuous heart rate measurement thanks to a new optical sensor. The previous model only tracked the pulse during sleep at night. A monthly subscription plan is available for $ 6.99 and is free for six months for pre-orders. Subscription isn’t mandatory, but it does offer daily insights, personalized recommendations, and video tutorials.
The ring now uses seven health sensors, including blood oxygen measurement (SpO2), but they won’t be available until 2022. Interestingly, the company claims it can predict women’s cycle 30 days in advance using algorithms and body temperature measurements. You will receive a notification six days before your period starts. The Smart Ring learns from the measured values in order to be able to make more precise predictions.
The Oura Smart Ring is made of titanium, is waterproof up to 100 meters and weighs between 4 and 6 grams, depending on the size. Even with all tracking functions activated, the battery should last between 4 and 7 days, depending on whether the continuous heart rate measurement is running permanently.
The ring will hit the market on November 15th in silver, black and gold for 314 euros. Pre-orders are already possible.
