It doesn’t give you Blood Pressure
I subscribed based on advert that it gives blood pressure readings. However, it doesn’t; it only measures the heart rate and tells you if it is healthy. I also noticed that it gives inaccurate readings about stress and tension as it gives high while other devices such as Apple Watch, Garmin and Whoop gives normal readings. Unfortunately you will not be able to see metrics unless you subscribe at least for one week.
