What is a smart ring and what functions does it offer?
A smart ring is a small device with sensors that measure health variables such as heart rate, blood oxygen level, sleep quality, and physical activity.
They don't have a screen. They sync with an app on the phone, allowing their autonomy to extend up to a week or more.
How are they used?
They are designed to be worn all day, even while sleeping or showering. Most have water resistance with IP68 certification.
