Is it reliable for Hong Niao Health Cloud mobile phone to measure blood pressure?

I think it's very reliable. I bought one. I saw it at CES last time. The built-in chips are very professional. I bought it when I returned to China. Personally, I think it is very valuable for daily monitoring of body data, such as blood pressure, blood sugar, blood oxygen, electrocardiogram, respiratory rate, alcohol content, body temperature and so on. Mainly it is very convenient to use. It can be used to measure blood sugar and blood pressure, and all the data can be stored in your own account. Doctors can use these data to evaluate their physical condition.
