Smart hardware players may also remember that there is a smart ring called Oura abroad. On October 27, the third generation of Oura 3 smart ring was officially released. A small ring integrates 7 sensors to support data detection such as heart rate/blood oxygen saturation, exercise, temperature, etc., and the battery life starts in 4 days.
Oura 3 smart ring is available in silver/gray/black/gold 4 colors, the outside is titanium alloy, the inside is transparent plastic material, 7.9mm wide, 2.55mm thick, 100 meters waterproof, different sizes of weight between 4 and 6g, using Bluetooth connection, integrated including heart rate, blood oxygen, temperature and other 7 kinds of sensors.
The function of oura 3 smart ring is consistent with the smart bracelet, supporting basic functions such as step counting, exercise and sleep monitoring, sports heart rate, route, distance, pace, heart rate recovery prediction and other functions are readily available, and also supports 24-hour heart rate measurement (the previous generation can only measure heart rate when sleeping), claiming that the heart rate measurement accuracy is 99.6%.
It also has a 24-hour temperature check and period prediction, claiming to be able to predict your period up to 30 days in advance and send notifications up to 6 days before your period begins. The oxygen saturation detection function is only turned on during sleep, and OTA is expected in 2022.
This generation is close to the size of ordinary rings and maintains a battery life of 4 to 7 days (depending on the size of the ring), and the charging time is between 20 and 80 minutes (also varies depending on the size of the ring). Oura 3 smart rings cost $299, or about $1,900, and go on sale on November 15.
